Forward-Looking Statements

This report contains statements that do not directly or exclusively relate to historical facts. These statements are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements can typically be identified by the use of forward-looking words, such as "will," "may," "could," "project," "believe," "anticipate," "expect," "estimate," "continue," "intend," "potential," "plan," "forecast" and similar terms. These statements are based upon PacifiCorp's current intentions, assumptions, expectations and beliefs and are subject to risks, uncertainties and other important factors. Many of these factors are outside the control of PacifiCorp and could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These factors include, among others:

• general economic, political and business conditions, as well as changes in, and compliance with, laws and regulations, including reliability and safety standards, affecting PacifiCorp's operations or related industries;

• changes in, and compliance with, environmental laws, regulations, decisions and policies that could, among other items, increase operating and capital costs, reduce generating facility output, accelerate generating facility retirements or delay generating facility construction or acquisition;

• the outcome of rate cases and other proceedings conducted by regulatory commissions or other governmental and legal bodies and PacifiCorp's ability to recover costs in rates in a timely manner;

• changes in economic, industry or weather conditions, as well as demographic trends, new technologies and various conservation, energy efficiency and distributed generation measures and programs, that could affect customer growth and usage, electricity supply or PacifiCorp's ability to obtain long-term contracts with customers and suppliers;

• a high degree of variance between actual and forecasted load or generation that could impact PacifiCorp's hedging strategy and the cost of balancing its generation resources with its retail load obligations;

• performance and availability of PacifiCorp's generating facilities, including the impacts of outages and repairs, transmission constraints, weather, including wind and hydroelectric conditions, and operating conditions;

• hydroelectric conditions and the cost, feasibility and eventual outcome of hydroelectric relicensing proceedings, that could have a significant impact on generating capacity and cost and PacifiCorp's ability to generate electricity;

• changes in prices, availability and demand for wholesale electricity, coal, natural gas, other fuel sources and fuel transportation that could have a significant impact on generating capacity and energy costs;

• the financial condition and creditworthiness of PacifiCorp's significant customers and suppliers;

• changes in business strategy or development plans;

• availability, terms and deployment of capital, including reductions in demand for investment-grade commercial paper, debt securities and other sources of debt financing and volatility in the London Interbank Offered Rate, the base interest rate for PacifiCorp's credit facilities;

• changes in PacifiCorp's credit ratings;

• the impact of certain contracts used to mitigate or manage volume, price and interest rate risk, including increased collateral requirements, and changes in commodity prices, interest rates and other conditions that affect the fair value of certain contracts;

• the impact of inflation on costs and PacifiCorp's ability to recover such costs in rates;

• increases in employee healthcare costs, including the implementation of the Affordable Care Act;

• the impact of investment performance and changes in interest rates, legislation, healthcare cost trends, mortality and morbidity on pension and other postretirement benefits expense and funding requirements;

iii

• unanticipated construction delays, changes in costs, receipt of required permits and authorizations, ability to fund capital projects and other factors that could affect future generating facilities and infrastructure additions;

• the impact of new accounting guidance or changes in current accounting estimates and assumptions on PacifiCorp's consolidated financial results;

• other risks or unforeseen events, including the effects of storms, floods, fires, earthquakes, explosions, landslides, litigation, wars, terrorism, embargoes and other catastrophic events, including catastrophic events triggered by a breakdown or failure of PacifiCorp's operating assets; and

• other business or investment considerations that may be disclosed from time to time in PacifiCorp's filings with the SEC or in other publicly disseminated written documents.

Further details of the potential risks and uncertainties affecting PacifiCorp are described in its filings with the SEC, including Part II, Item 1A and other discussions contained in this Form 10-Q. PacifiCorp undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The foregoing factors should not be construed as exclusive.

PART I

Item 1. Financial Statements

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

PacifiCorp

Portland, Oregon

We have reviewed the accompanying consolidated balance sheet of PacifiCorp and subsidiaries ("PacifiCorp") as of September 30, 2013, and the related consolidated statements of operations for the three-month and nine-month periods ended September 30, 2013 and 2012, and of changes in shareholders' equity and cash flows for the nine-month periods ended September 30, 2013 and 2012. These interim financial statements are the responsibility of PacifiCorp's management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to such consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of PacifiCorp and subsidiaries as of December 31, 2012, and the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for the year then ended (not presented herein); and in our report dated March 1, 2013, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2012 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

PACIFICORP AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) General

PacifiCorp, which includes PacifiCorp and its subsidiaries, is a United States regulated electric company serving retail customers, including residential, commercial, industrial, irrigation and other customers in portions of the states of Utah, Oregon, Wyoming, Washington, Idaho and California. PacifiCorp owns, or has interests in, a number of thermal, hydroelectric, wind-powered and geothermal generating facilities, as well as electric transmission and distribution assets. PacifiCorp also buys and sells electricity on the wholesale market with public and private utilities, energy marketing companies, financial institutions and incorporated municipalities. PacifiCorp is subject to comprehensive state and federal regulation. PacifiCorp's subsidiaries support its electric utility operations by providing coal mining services. PacifiCorp is an indirect subsidiary of MidAmerican Energy Holdings Company ("MEHC"), a holding company based in Des Moines, Iowa that owns subsidiaries principally engaged in energy businesses. MEHC is a consolidated subsidiary of Berkshire Hathaway Inc. ("Berkshire Hathaway").

The unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Consolidated Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the Consolidated Financial Statements as of September 30, 2013 and for the three- and nine-month periods ended September 30, 2013 and 2012. The results of operations for the three- and nine-month periods ended September 30, 2013 are not necessarily indicative of the results to be expected for the full year.

The preparation of the unaudited Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Consolidated Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Consolidated Financial Statements. Note 2 of Notes to Consolidated Financial Statements included in PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2012 describes the most significant accounting policies used in the preparation of the unaudited Consolidated Financial Statements. There have been no significant changes in PacifiCorp's assumptions regarding significant accounting estimates and policies during the nine-month period ended September 30, 2013.

(2) New Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-04, which amends FASB Accounting Standards Codification ("ASC") Topic 405, "Liabilities." The amendments in this guidance require an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the amount the reporting entity agreed to pay plus any additional amounts the reporting entity expects to pay on behalf of its co-obligor. Additionally, the guidance requires the entity to disclose the nature and amount of the obligation, as well as other information about those obligations. This guidance is effective for interim and annual reporting periods beginning after December 15, 2013. PacifiCorp is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements.

In February 2013, the FASB issued ASU No. 2013-02, which amends FASB ASC Topic 220, "Comprehensive Income." The amendments in this guidance require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required by GAAP that provide additional detail about those amounts. PacifiCorp adopted this guidance on January 1, 2013. The adoption of this guidance did not have a material impact on PacifiCorp's disclosures included within Notes to Consolidated Financial Statements.

7

In December 2011, the FASB issued ASU No. 2011-11, which amends FASB ASC Topic 210, "Balance Sheet." The amendments in this guidance require an entity to provide quantitative disclosures about offsetting financial instruments and derivative instruments. Additionally, this guidance requires qualitative and quantitative disclosures about master netting agreements or similar agreements when the financial instruments and derivative instruments are not offset. In January 2013, the FASB issued ASU No. 2013-01, which also amends FASB ASC Topic 210 to clarify that the scope of ASU No. 2011-11 only applies to derivative instruments, repurchase agreements, reverse purchase agreements and securities borrowing and securities lending transactions that are either being offset or are subject to an enforceable master netting arrangement or similar agreement. PacifiCorp adopted the guidance on January 1, 2013. The adoption of the guidance did not have a material impact on PacifiCorp's disclosures included within Notes to Consolidated Financial Statements.

(3) Property, Plant and Equipment, Net

Property, plant and equipment, net consists of the following (in millions):

		As of
		September 30,			December 31,
	Depreciable Life	2013			2012
Property, plant and equipment	5-80 years	$	24,686		$	24,024
Accumulated depreciation and amortization		(7,564		)	(7,222		)
Net property, plant and equipment in service		17,122			16,802
Construction work-in-progress		1,215			1,255
Total property, plant and equipment, net		$	18,337		$	18,057

(4) Recent Financing Transactions

In June 2013, PacifiCorp issued $300 million of its 2.95% First Mortgage Bonds due June 2023. The net proceeds were used to fund capital expenditures and for general corporate purposes, including a portion of the common stock dividend paid to PPW Holdings LLC, a direct wholly owned subsidiary of MEHC and PacifiCorp's direct parent company, in June 2013.

In March 2013, PacifiCorp replaced its $630 million unsecured revolving credit facility, which had been set to expire in July 2013, with a $600 million unsecured revolving credit facility expiring in March 2018. The new credit facility, which supports PacifiCorp's commercial paper program, certain series of its tax-exempt bond obligations and provides for the issuance of letters of credit, has a variable interest rate based on the London Interbank Offered Rate or a base rate, at PacifiCorp's option, plus a spread that varies based on PacifiCorp's credit ratings for its senior unsecured long-term debt securities. As of September 30, 2013, PacifiCorp had no borrowings outstanding under this credit facility. The credit facility requires that PacifiCorp's ratio of consolidated debt, including current maturities, to total capitalization not exceed 0.65 to 1.0 as of the last day of each quarter. As of September 30, 2013, $270 million of letters of credit were issued under this credit agreement to support variable-rate tax-exempt bond obligations. These letters of credit were previously issued under the credit facility that was replaced.

In March 2013, PacifiCorp obtained $289 million of letters of credit to support variable-rate tax-exempt bond obligations. These letters of credit expire through March 2015 and replaced certain letters of credit previously issued under one of the revolving credit facilities.

As of December 31, 2012, PacifiCorp had $68 million of tax-exempt bond obligations with fixed interest rates, ranging from 3.90% to 4.13%, scheduled to reset to variable or fixed interest rates in June 2013. In June 2013, $17 million of these tax-exempt bond obligations were redeemed and retired prior to their scheduled 2014 maturity date. The interest rates for the remaining $51 million, with maturity dates ranging from 2014 to 2025, were reset to variable interest rates with a weighted average interest rate of 0.24% as of September 30, 2013.

(5) Employee Benefit Plans

Net periodic benefit cost for the pension and other postretirement benefit plans included the following components (in millions):

	Three-Month Periods						Nine-Month Periods
	Ended September 30,						Ended September 30,
	2013			2012			2013			2012
Pension:
Service cost	$	1		$	2		$	4		$	6

Net amortization	2			1			6			3
Net periodic benefit cost	$	3		$	3		$	9		$	7

Employer contributions to the pension and other postretirement benefit plans are expected to be $64 million and $13 million, respectively, during 2013. As of September 30, 2013, $62 million and $4 million of contributions had been made to the pension and other postretirement benefit plans, respectively.

(6)Risk Management and Hedging Activities

PacifiCorp is exposed to the impact of market fluctuations in commodity prices and interest rates. PacifiCorp is principally exposed to electricity, natural gas, coal and fuel oil commodity price risk as it has an obligation to serve retail customer load in its regulated service territories. PacifiCorp's load and generating facilities represent substantial underlying commodity positions. Exposures to commodity prices consist mainly of variations in the price of fuel required to generate electricity and wholesale electricity that is purchased and sold. Commodity prices are subject to wide price swings as supply and demand are impacted by, among many other unpredictable items, weather, market liquidity, generating facility availability, customer usage, storage, and transmission and transportation constraints. Interest rate risk exists on variable-rate debt and future debt issuances. PacifiCorp does not engage in a material amount of proprietary trading activities.

PacifiCorp has established a risk management process that is designed to identify, assess, monitor, report, manage and mitigate each of the various types of risk involved in its business. To mitigate a portion of its commodity price risk, PacifiCorp uses commodity derivative contracts, which may include forwards, options, swaps and other agreements, to effectively secure future supply or sell future production generally at fixed prices. PacifiCorp manages its interest rate risk by limiting its exposure to variable interest rates primarily through the issuance of fixed-rate long-term debt and by monitoring market changes in interest rates. Additionally, PacifiCorp may from time to time enter into interest rate derivative contracts, such as interest rate swaps or locks, to mitigate PacifiCorp's exposure to interest rate risk. No interest rate derivatives were in place during the periods presented. PacifiCorp does not hedge all of its commodity price and interest rate risks, thereby exposing the unhedged portion to changes in market prices.

There have been no significant changes in PacifiCorp's accounting policies related to derivatives. Refer to Note 7 for additional information on derivative contracts.

Credit Risk

PacifiCorp extends unsecured credit to other utilities, energy marketing companies, financial institutions and other market participants in conjunction with its wholesale energy supply and marketing activities. Credit risk relates to the risk of loss that might occur as a result of nonperformance by counterparties on their contractual obligations to make or take delivery of electricity, natural gas or other commodities and to make financial settlements of these obligations. Credit risk may be concentrated to the extent that one or more groups of counterparties have similar economic, industry or other characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in market or other conditions. In addition, credit risk includes not only the risk that a counterparty may default due to circumstances relating directly to it, but also the risk that a counterparty may default due to circumstances involving other market participants that have a direct or indirect relationship with the counterparty.

PacifiCorp analyzes the financial condition of each significant wholesale counterparty before entering into any transactions, establishes limits on the amount of unsecured credit to be extended to each counterparty and evaluates the appropriateness of unsecured credit limits on an ongoing basis. To mitigate exposure to the financial risks of wholesale counterparties, PacifiCorp enters into netting and collateral arrangements that may include margining and cross-product netting agreements and obtains third-party guarantees, letters of credit and cash deposits. Counterparties may be assessed fees for delayed payments. If required, PacifiCorp exercises rights under these arrangements, including calling on the counterparty's credit support arrangement.

Collateral and Contingent Features

In accordance with industry practice, certain wholesale derivative contracts contain credit support provisions that in part base certain collateral requirements on credit ratings for senior unsecured debt as reported by one or more of the three recognized credit rating agencies. These derivative contracts may either specifically provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features") or provide the right for counterparties to demand "adequate assurance" in the event of a material adverse change in PacifiCorp's creditworthiness. These rights can vary by contract and by counterparty. As of September 30, 2013, PacifiCorp's credit ratings from the three recognized credit rating agencies were investment grade.

The aggregate fair value of PacifiCorp's derivative contracts in liability positions with specific credit-risk-related contingent features totaled $74 million and $153 million as of September 30, 2013 and December 31, 2012, respectively, for which PacifiCorp had posted collateral of $12 million and $56 million, respectively, in the form of cash deposits and letters of credit. If all credit-risk-related contingent features for derivative contracts in liability positions had been triggered as of September 30, 2013 and December 31, 2012, PacifiCorp would have been required to post $53 million and $73 million, respectively, of additional collateral. PacifiCorp's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation or other factors.

(7) Fair Value Measurements

The carrying value of PacifiCorp's cash, certain cash equivalents, receivables, payables, accrued liabilities and short-term borrowings approximates fair value because of the short-term maturity of these instruments. PacifiCorp has various financial assets and liabilities that are measured at fair value on the Consolidated Financial Statements using inputs from the three levels of the fair value hierarchy. A financial asset or liability classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows:

• Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that PacifiCorp has the ability to access at the measurement date.

• Level 2 - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

• Level 3 - Unobservable inputs reflect PacifiCorp's judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. PacifiCorp develops these inputs based on the best information available, including its own data.

The following table presents PacifiCorp's assets and liabilities recognized on the Consolidated Balance Sheets and measured at fair value on a recurring basis (in millions):

(1) Represents netting under master netting arrangements and a net cash collateral receivable of $12 million and $55 million as of September 30, 2013 and December 31, 2012, respectively.

(2) Amounts are included in cash and cash equivalents, other current assets and other assets on the Consolidated Balance Sheets. The fair value of these money market mutual funds approximates cost.

12

Derivative contracts are recorded on the Consolidated Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchases or normal sales and qualify for the exception afforded by GAAP. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which PacifiCorp transacts. When quoted prices for identical contracts are not available, PacifiCorp uses forward price curves. Forward price curves represent PacifiCorp's estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates. PacifiCorp bases its forward price curves upon market price quotations, when available, or internally developed and commercial models, with internal and external fundamental data inputs. Market price quotations are obtained from independent energy brokers, exchanges, direct communication with market participants and actual transactions executed by PacifiCorp. Market price quotations for certain major electricity and natural gas trading hubs are generally readily obtainable for the first six years; therefore, PacifiCorp's forward price curves for those locations and periods reflect observable market quotes. Market price quotations for other electricity and natural gas trading hubs are not as readily obtainable for the first six years. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, PacifiCorp uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of underlying forward commodity prices, interest rates, currency rates, related volatility, counterparty creditworthiness and duration of contracts. Refer to Note 6 for further discussion regarding PacifiCorp's risk management and hedging activities.

PacifiCorp's investments in money market mutual funds are accounted for as available-for-sale securities and are stated at fair value. PacifiCorp uses a readily observable quoted market price to record the fair value.

PacifiCorp's long-term debt is carried at cost on the Consolidated Financial Statements. The fair value of PacifiCorp's long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying value of PacifiCorp's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates. The following table presents the carrying value and estimated fair value of PacifiCorp's long-term debt (in millions):

	As of September 30, 2013				As of December 31, 2012
	Carrying		Fair		Carrying		Fair

(8) Commitments and Contingencies

Legal Matters

PacifiCorp is party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. PacifiCorp does not believe that such normal and routine litigation will have a material impact on its consolidated financial results. PacifiCorp is also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines, penalties and other costs in substantial amounts and are described below.

USA Power

In October 2005, prior to MEHC's ownership of PacifiCorp, PacifiCorp was added as a defendant to a lawsuit originally filed in February 2005 in the Third District Court of Salt Lake County, Utah ("Third District Court") by USA Power, LLC, USA Power Partners, LLC and Spring Canyon Energy, LLC (collectively, the "Plaintiff"). The Plaintiff's complaint alleged that PacifiCorp misappropriated confidential proprietary information in violation of Utah's Uniform Trade Secrets Act and accused PacifiCorp of breach of contract and related claims in regard to the Plaintiff's 2002 and 2003 proposals to build a natural gas-fueled generating facility in Juab County, Utah. In October 2007, the Third District Court granted PacifiCorp's motion for summary judgment on all counts and dismissed the Plaintiff's claims in their entirety. In February 2008, the Plaintiff filed a petition requesting consideration by the Utah Supreme Court. In May 2010, the Utah Supreme Court reversed summary judgment and remanded the case back to the Third District Court for further consideration, which led to a trial that began in April 2012. In May 2012, the jury reached a verdict in favor of the Plaintiff on its claims. The jury awarded damages to the Plaintiff for breach of contract and misappropriation of a trade secret in the amounts of $18 million for actual damages and $113 million for unjust enrichment. In May 2012, the Plaintiff filed a motion seeking exemplary damages. Under the Utah Uniform Trade Secrets law, the judge may award exemplary damages in an additional amount not to exceed twice the original award. The Plaintiff also filed a motion to seek recovery of attorneys' fees in an amount equal to 40% of all amounts ultimately awarded in the case. In October 2012, PacifiCorp filed post-trial motions for a judgment notwithstanding the verdict and a new trial (collectively, "PacifiCorp's post-trial motions"). The trial judge stayed briefing on the Plaintiff's motions, pending resolution of PacifiCorp's post-trial motions. As a result of a hearing in December 2012, the trial judge denied PacifiCorp's post-trial motions with the exception of reducing the aggregate amount of damages to $113 million. In January 2013, the Plaintiff filed a motion for prejudgment interest. In the first quarter of 2013, PacifiCorp filed its responses to the Plaintiff's post-trial motions for exemplary damages, attorneys' fees and prejudgment interest. An initial judgment was entered in April 2013 in which the trial judge denied the Plaintiff's motions for exemplary damages and prejudgment interest and ruled that PacifiCorp must pay the Plaintiff's attorneys' fees based on applying a reasonable rate to hours worked rather than the Plaintiff's request for an amount equal to 40% of all amounts ultimately awarded. In May 2013, a final judgment was entered against PacifiCorp in the amount of $115 million, which includes the $113 million of aggregate damages previously awarded and amounts awarded for the Plaintiff's attorneys' fees. The final judgment also ordered that postjudgment interest accrue beginning as of the date of the April 2013 initial judgment. In May 2013, PacifiCorp posted a surety bond issued by a subsidiary of Berkshire Hathaway to secure its estimated obligation. Both PacifiCorp and the Plaintiff filed appeals with the Utah Supreme Court. PacifiCorp strongly disagrees with the jury's verdict and plans to vigorously pursue all appellate measures. The appeals are awaiting a briefing schedule to be set by the Utah Supreme Court. As of September 30, 2013, PacifiCorp had accrued $116 million for the final judgment and postjudgment interest, and believes the likelihood of any additional material loss is remote; however, any additional awards against PacifiCorp could also have a material effect on the consolidated financial results. Any payment of damages will be at the end of the appeals process, which could take as long as several years.

Northwest Refund Case

In October 2011, the Federal Energy Regulatory Commission ("FERC") issued an order on remand by the United States Court of Appeals for the Ninth Circuit, in which it determined that additional procedures are needed to address possible unlawful activity that may have influenced prices in the Pacific Northwest wholesale spot market during the period from December 2000 through June 2001. PacifiCorp was a participant in the Pacific Northwest wholesale spot market during this period. The FERC ordered an evidentiary, trial-type hearing before an administrative law judge to permit parties to present evidence of alleged unlawful market activity. However, the FERC held the hearing in abeyance pending settlement discussions among all parties. The plaintiff parties to the proceeding filed claims against multiple parties, including PacifiCorp. PacifiCorp entered into settlements with the plaintiff parties, and the resulting settlements were approved by the FERC. The outcome of such settlements did not have a material impact on PacifiCorp's consolidated financial results. The FERC, however, declined to dismiss PacifiCorp from the case entirely, noting that additional parties may, in the future, assert sequential claims against parties to the case, including PacifiCorp. PacifiCorp believes it is unlikely that the FERC will address sequential claims until after the primary cases have proceeded through the trial-type hearing. Due to the uncertainties associated with the sequential claims, PacifiCorp is unable to predict the outcome and the impact of any claims on its consolidated financial results.

Environmental Laws and Regulations

PacifiCorp is subject to federal, state and local laws and regulations regarding air and water quality, renewable portfolio standards, emissions performance standards, climate change, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact PacifiCorp's current and future operations. PacifiCorp believes it is in material compliance with all applicable laws and regulations.

Purchase Obligations

In August 2013, PacifiCorp amended an existing coal supply agreement for its coal-fueled generating facilities by exercising a five-year extension period. The amended coal supply agreement results in minimum future purchases of $95 million in 2016, $96 million in 2017 and $298 million in 2018 and thereafter.

(9) Shareholders' Equity

In May 2013, PacifiCorp redeemed and canceled the remaining shares of its $100 stated value 5.00% Serial Preferred Stock at the redemption price of $100 per share plus accrued and unpaid dividends.

In October 2013, PacifiCorp called for the redemption of all remaining outstanding redeemable shares of five of its series of preferred stock at stated redemption prices, which in aggregate total $36 million, plus accrued and unpaid dividends. The redemption and cancellation of the shares will take place in November 2013. Following this redemption, PacifiCorp will have two remaining non-redeemable preferred stock series outstanding with an aggregate stated value of $2 million.

(10) Related-Party Transactions

Berkshire Hathaway includes MEHC and its subsidiaries in its United States federal income tax return. Consistent with established regulatory practice, PacifiCorp's provision for income taxes has been computed on a stand-alone basis, and substantially all of its currently payable or receivable income taxes are remitted to or received from MEHC. For the nine-month period endedSeptember 30, 2013, PacifiCorp made net cash payments for income taxes to MEHC totaling $69 million. For the nine-month period endedSeptember 30, 2012, PacifiCorp received net cash payments for income taxes from MEHC totaling $210 million.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following is management's discussion and analysis of certain significant factors that have affected the consolidated financial condition and results of operations of PacifiCorp during the periods included herein. Explanations include management's best estimate of the impacts of weather, customer growth and other factors. This discussion should be read in conjunction with PacifiCorp's historical unaudited Consolidated Financial Statements and Notes to Consolidated Financial Statements in Item 1 of this Form 10-Q. PacifiCorp's actual results in the future could differ significantly from the historical results.

Results of Operations for the Third Quarter and First Nine Months of 2013 and 2012

Overview

Net income for the third quarter of 2013 was $216 million, an increase of $4 million, or 2%, as compared to 2012. Net income increased primarily due to higher retail prices approved by regulators, higher wholesale electricity revenue and higher retail customer load, partially offset by higher purchased electricity, lower REC revenue, higher operations and maintenance expense, and higher depreciation and amortization expense. Retail customer load increased 1% in the third quarter of 2013 compared to 2012 primarily due to the impacts of hotter weather and higher industrial customer usage, partially offset by lower residential and irrigation customer usage. Energy generated increased 4% in the third quarter of 2013 compared to 2012 due to higher natural gas-fueled and wind-powered generation, partially offset by lower hydroelectric generation.

Net income for the nine months of 2013 was $542 million, an increase of $49 million, or 10%, as compared to 2012. Net income increased primarily due to higher retail prices approved by regulators, lower natural gas costs, higher retail customer load and lower operations and maintenance expense, partially offset by higher purchased electricity, lower REC revenue, higher coal costs, higher income tax expense and higher depreciation and amortization expense. Retail load increased 2% in the first nine months of 2013 compared to 2012 primarily due to the impacts of hotter weather in the third quarter and colder weather in the first quarter and higher industrial and commercial customer usage, partially offset by lower residential customer usage. Energy generated increased 1% for the first nine months of 2013 compared to 2012 due to higher coal-fueled generation, partially offset by lower hydroelectric generation.

Operating revenue and energy costs are the key drivers of PacifiCorp's results of operations as they encompass retail and wholesale electricity revenue and the direct costs associated with providing electricity to customers. PacifiCorp believes that a discussion of gross margin, representing operating revenue less energy costs, is therefore meaningful.

(3) The average cost per MWh of energy generated includes the cost of fuel associated with the generating facilities and does not include other costs.

17

Gross margin increased $30 million, or 4%, for the third quarter of 2013 compared to 2012 primarily due to:

• $69 million of increases substantially due to higher retail prices approved by regulators;

• $8 million of higher wholesale electricity revenue due to higher average market prices;

• $7 million of higher retail customer load due to the impacts of hotter weather on residential and commercial customer load and higher industrial customer usage primarily in the eastern portion of PacifiCorp’s service territory, partially offset by lower residential and irrigation customer usage; and

• $7 million of lower natural gas costs due to lower average unit costs, partially offset by increased generation.

The increase in gross margin was partially offset by:

• $38 million of higher purchased electricity due to higher average market prices, partially offset by decreased volumes;

• $14 million of lower REC revenue;

• $6 million of higher coal costs; and

• $5 million of lower net deferrals of incurred power costs in accordance with established adjustment mechanisms.

Operations and maintenance increased $9 million, or 3%, for the third quarter of 2013 compared to 2012 in part due to charges related to certain fire and other damage claims.

Depreciation and amortization increased $8 million, or 5%, for the third quarter of 2013 compared to 2012 due to higher plant in-service and accelerated depreciation rates for Oregon's share of the Carbon coal-fueled generating facility ("Carbon Facility") expected to be retired in 2015.

Gross margin increased $101 million, or 4%, for the first nine months of 2013 compared to 2012 primarily due to:

• $183 million of increases substantially due to higher retail prices approved by regulators;

• $52 million of lower natural gas costs due to lower average unit costs, partially offset by increased generation;

• $42 million of higher retail customer load due to the impacts of hotter weather in the third quarter of 2013 and colder weather in the first quarter of 2013 on residential and commercial customer load, higher industrial customer usage primarily in the eastern portion of PacifiCorp’s service territory, an increase in the average number of residential customers and higher commercial customer usage, partially offset by lower residential customer usage; and

• $7 million of higher wholesale electricity revenue due to higher average market prices, partially offset by lower volumes.

The increase in gross margin was partially offset by:

• $81 million of higher purchased electricity due to higher average market prices and lower gains on electricity swaps, partially offset by decreased volumes;

• $60 million of lower REC revenue;

• $39 million of higher coal costs due to increased generation and higher unit costs; and

• $12 million of lower net deferrals of incurred power costs in accordance with established adjustment mechanisms.

Operations and maintenance decreased $22 million, or 3%, for the first nine months of 2013 compared to 2012 due to lower charges for certain litigation, fire and other damage claims and lower maintenance expense.

Depreciation and amortization increased $28 million, or 6%, for the first nine months of 2013 compared to 2012 primarily due to higher plant in-service and accelerated depreciation rates for Oregon's share of the Carbon Facility.

18

Income tax expense increased $37 million, or 19%, for the first nine months of 2013 compared to 2012 and the effective tax rates were 30% and 29%, respectively. The increase in PacifiCorp’s effective tax rate was primarily due to changes in unrecognized tax benefits in the prior period.

Liquidity and Capital Resources

As of September 30, 2013, PacifiCorp's total net liquidity was $1.036 billion as follows (in millions):

Cash and cash equivalents	$	157
Available unsecured revolving credit facilities(1)	1,200

Operating Activities

Net cash flows from operating activities for the nine-month periods ended September 30, 2013 and 2012 were $1.297 billion and $1.355 billion, respectively. The $58 million decrease was primarily due to cash paid for income taxes in the current year versus cash received for income taxes in the prior year primarily due to the effects of lower bonus depreciation in 2013, higher purchased electricity prices and lower REC sales, partially offset by higher collections from retail customers due to higher prices approved by regulators and increased retail customer load and lower fuel payments.

Investing Activities

Net cash flows from investing activities for the nine-month periods endedSeptember 30,2013 and 2012 were $(737) million and $(1.037) billion, respectively. Capital expenditures decreased $285 million and consisted of the following during the nine-month periods endedSeptember 30 and exclude amounts for non-cash equity AFUDC and other non-cash items:

• Transmission system investments totaling $181 million, including construction costs for the 170-mile single-circuit 345-kV Sigurd-Red Butte ("Sigurd-Red Butte") transmission line expected to be placed in-service in 2015 and the 100-mile high-voltage Mona-Oquirrh ("Mona-Oquirrh") transmission line that was placed in-service in May 2013.

• The construction of the Lake Side 2 645-MW combined-cycle combustion turbine natural gas-fueled generating facility ("Lake Side 2") totaling $116 million, which is expected to be placed in-service in 2014.

• Emissions control equipment on existing generating facilities totaling $31 million for installation or upgrade of sulfur dioxide scrubbers, low nitrogen oxide burners and particulate matter control systems.

• Distribution, generation, mining and other infrastructure totaling $424 million.

2012:

• Transmission system investments totaling $250 million, including construction costs for the Mona-Oquirrh transmission line.

• The development and construction of Lake Side 2 totaling $177 million.

• Emissions control equipment on existing generating facilities totaling $66 million for installation or upgrade of sulfur dioxide scrubbers, low nitrogen oxide burners and particulate matter control systems.

• Distribution, generation, mining and other infrastructure totaling $544 million.

Financing Activities

Net cash flows from financing activities for the nine-month period endedSeptember 30,2013 were $(483) million. Uses of cash totaled $782 million and consisted substantially of $500 million for common stock dividends paid to PPW Holdings and $268 million for the repayment of long-term debt. Sources of cash totaled $299 million and consisted of proceeds from the issuance of long-term debt.

Net cash flows from financing activities for the nine-month period endedSeptember 30,2012 were $(190) million. Uses of cash totaled $939 million and consisted substantially of $688 million for the net repayment of short-term debt, $150 million for common stock dividends paid to PPW Holdings and $90 million for the repayment of long-term debt. Sources of cash totaled $749 million and consisted of proceeds from the issuance of long-term debt.

Long-term Debt

In June 2013, PacifiCorp issued $300 million of its 2.95% First Mortgage Bonds due June 2023. The net proceeds were used to fund capital expenditures and for general corporate purposes, including a portion of the common stock dividend paid to PPW Holdings, in June 2013.

PacifiCorp currently has regulatory authority from the OPUC and the IPUC to issue an additional $550 million of long-term debt. PacifiCorp must make a notice filing with the WUTC prior to any future issuance.

Preferred Stock

In May 2013, PacifiCorp redeemed and canceled the remaining shares of its $100 stated value 5.00% Serial Preferred Stock at the redemption price of $100 per share plus accrued and unpaid dividends.

20

In October 2013, PacifiCorp called for the redemption of all remaining outstanding redeemable shares of five of its series of preferred stock at stated redemption prices, which in aggregate total $36 million, plus accrued and unpaid dividends. The redemption and cancellation of the shares will take place in November 2013. Following this redemption, PacifiCorp will have two remaining non-redeemable preferred stock series outstanding with an aggregate stated value of $2 million.

Future Uses of Cash

PacifiCorp has available a variety of sources of liquidity and capital resources, both internal and external, including net cash flows from operating activities, public and private debt offerings, the issuance of commercial paper, the use of unsecured revolving credit facilities, capital contributions and other sources. These sources are expected to provide funds required for current operations, capital expenditures, debt retirements and other capital requirements. The availability and terms under which PacifiCorp has access to external financing depends on a variety of factors, including PacifiCorp's credit ratings, investors' judgment of risk and conditions in the overall capital market, including the condition of the utility industry.

Capital Expenditures

PacifiCorp has significant future capital requirements. Capital expenditure needs are reviewed regularly by management and may change significantly as a result of these reviews, which may consider, among other factors, changes in environmental and other rules and regulations; impacts to customers' rates; outcomes of regulatory proceedings; changes in income tax laws; general business conditions; load projections; system reliability standards; the cost and efficiency of construction labor, equipment and materials; commodity prices; and the cost and availability of capital. Prudently incurred expenditures for compliance-related items, such as pollution-control technologies, replacement generation, hydroelectric relicensing, hydroelectric decommissioning and associated operating costs are generally incorporated into PacifiCorp's rates.

Forecasted capital expenditures, which exclude amounts for non-cash equity AFUDC and other non-cash items, are approximately $1.1 billion for the year ended December 31, 2013 and include the following:

• $247 million for transmission system investments, including projects for the Energy Gateway Transmission Expansion Program, which includes construction costs of $104 million for the Sigurd-Red Butte transmission line, $54 million for the Mona-Oquirrh transmission line that was placed in-service in May 2013 and $41 million for other segments that are expected to be placed in-service over the next several years, depending on siting, permitting and construction schedules.

• $157 million for construction of Lake Side 2, which is expected to be placed in-service in 2014.

• $68 million for environmental projects, which includes emissions control equipment to meet air quality and visibility targets, including the reduction of sulfur dioxide, nitrogen oxides and particulate matter emissions. This estimate includes the installation of new or the replacement of existing emissions control equipment at a number of units at several of PacifiCorp's coal-fueled generating facilities, including Hunter Unit 1 and Jim Bridger Units 3 and 4.

• Remaining amounts are for ongoing investments in distribution, generation, mining and other infrastructure needed to serve existing and expected demand.

Integrated Resource Plan

In April 2013, PacifiCorp filed its 2013 IRP with the state commissions. In September 2013, the WPSC accepted the 2013 IRP into its files and the IPUC acknowledged the 2013 IRP. PacifiCorp is awaiting acknowledgment of the 2013 IRP from the UPSC, the OPUC and the WUTC.

Contractual Obligations

As of September 30, 2013, there have been no material changes outside the normal course of business in contractual obligations from the information provided in Item 7 of PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2012 other than the 2013 debt issuance and capital expenditure matters previously discussed.

Regulatory Matters

PacifiCorp is subject to comprehensive regulation. The discussion below contains material developments to those matters disclosed in Item 7 of PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2012, and new regulatory matters occurring in 2013.

State Regulatory Matters

Utah

In March 2013, PacifiCorp filed its annual EBA with the UPSC requesting recovery of $17 million in deferred net power costs for the period January 1, 2012 through December 31, 2012 over a two-year period. In September 2013, PacifiCorp filed a stipulation with the UPSC providing for recovery of $15 million over a two-year period. In October 2013, the UPSC approved the stipulation with the new rates effective November 2013.

In March 2013, PacifiCorp filed with the UPSC to return $3 million to customers through the REC balancing account. In May 2013, the UPSC issued an order approving the new rates as filed effective June 2013 on an interim basis. In August 2013, the UPSC issued a final order approving the interim rates as final.

Oregon

In March 2013, PacifiCorp filed a general rate case with the OPUC requesting an annual increase of $56 million, or an average price increase of 5%. The request was reduced to $45 million, or an average price increase of 4%, as a result of the OPUC's approval of a separate tariff rider for the Mona-Oquirrh transmission line that was effective June 1, 2013. PacifiCorp's general rate case filing also included a request for a separate tariff rider for Lake Side 2. In July 2013, a multi-party stipulation was filed with the OPUC resolving all issues in the general rate case. The stipulation provides for an annual increase of $24 million, or an average price increase of 2%, which includes the impact of the revised depreciation rates. Refer to "Depreciation Rate Study" for discussion of the depreciation rate impacts. The stipulation also provides for the implementation of a separate tariff rider for Lake Side 2 when placed into service in mid-2014 with the final costs subject to a prudence determination. In addition, the stipulation specifies that January 2016 is the earliest effective date that PacifiCorp could seek an increase to customers' base rates through a general rate case. If the stipulation is approved by the OPUC, the new rates will be effective January 2014. The OPUC is expected to issue a decision no later than December 2013.

In March 2013, PacifiCorp made its initial filing for the annual TAM with the OPUC for an annual decrease of $1 million in anticipation of net power costs forecasted for calendar year 2014. In October 2013, the OPUC approved the TAM, with certain adjustments and subject to net power costs updates in November 2013. The new rates will become effective January 2014.

Wyoming

In March 2013, PacifiCorp filed its annual ECAM and RRA applications with the WPSC. The ECAM filing requested recovery of $18 million in deferred net power costs for the period January 1, 2012 to December 31, 2012 to be recovered over three years at $6 million per year pursuant to the settlement agreement in the 2012 ECAM case, which would result in a 1% increase in rates. The RRA filing requested a $15 million reduction in the RRA surcredit, or an increase in rates of 2%, to be recovered over one year. In May 2013, the WPSC approved the requested adjustments to rates on an interim basis subject to further investigation and hearing. In August 2013, PacifiCorp filed a stipulation with the WPSC in which the parties agreed to recovery of $17 million in deferred net power costs over three years and a $15 million reduction in the RRA surcredit. In September 2013, the WPSC approved the stipulation with the new rates effective November 2013.

Washington

In December 2012, PacifiCorp filed for judicial review of the WUTC's August and November 2012 orders regarding proceeds from the sales of RECs on or after January 1, 2009. In February 2013, PacifiCorp, WUTC staff and intervening parties submitted a joint filing with the WUTC proposing a tracking mechanism for REC sales revenues. In March 2013, the WUTC issued a notice stating that the February 2013 joint filing failed to comply with the WUTC's orders, primarily requiring PacifiCorp and other parties to clarify the period over which amortization of historical REC revenues (revenues from January 1, 2009 through April 2, 2011) would occur. In March 2013, PacifiCorp filed a response to the WUTC notice requesting that the WUTC not require amortization of historical REC revenues until after resolution of the pending judicial review of the WUTC's orders. WUTC staff and intervening parties submitted a joint response to the WUTC notice requesting the amortization of historical REC revenues begin on May 1, 2013 and be distributed as a one-time credit or amortized over one year. No action has been taken with regard to the parties' responses to the WUTC's notice. PacifiCorp is seeking judicial review of the WUTC's orders and in October 2013, filed its opening brief with the Washington State Court of Appeals.

In January 2013, PacifiCorp filed a general rate case with the WUTC requesting an annual increase of $43 million, or an average price increase of 14%. The requested increase includes the impacts associated with investments in PacifiCorp's facilities since the last general rate case filing, projected increases in net power costs and revised depreciation rates. In August 2013, PacifiCorp submitted rebuttal testimony reducing the requested increase to $37 million, or an average price increase of 12%. The WUTC is expected to issue a final decision by December 2013.

Idaho

In February 2013, PacifiCorp filed its annual ECAM application with the IPUC requesting recovery of $16 million of deferred net power costs, of which $9 million will be collected over a one-year period and the remainder collected over a three-year period. In March 2013, the IPUC approved the new rates, which became effective April 2013.

In June 2013, PacifiCorp filed a multi-party stipulation with the IPUC that would increase base rates $2 million effective January 2014 and approve the deferral of any removal costs incurred associated with the retirement of the Carbon Facility and any incremental depreciation expense associated with the revised depreciation rates reflected in the depreciation rate study, with timing of recovery to be determined in a future proceeding. Refer to "Depreciation Rate Study" for discussion of the depreciation rate impacts. In addition, a resource adder to provide a means for recovery of costs associated with Lake Side 2 would be included in the ECAM effective January 2015 for an estimated $5 million annually. This deferral would continue until Lake Side 2 is included in base rates. The stipulation also specifies that January 2016 is the earliest effective date that PacifiCorp could seek an increase to customers' base rates. In October 2013, the IPUC approved the stipulation.

California

In June 2013, PacifiCorp filed for a rate increase of $1 million, or 1%, pursuant to its PTAM for major capital additions to add Mona-Oquirrh to rates. In July 2013, the CPUC approved the rate increase effective July 2013.

In October 2013, PacifiCorp filed its annual PTAM attrition adjustment with the CPUC requesting an increase of $1 million, or an average price increase of 1%. If approved by the CPUC, the new rates will be effective January 2014.

Depreciation Rate Study

In January 2013, PacifiCorp filed applications for depreciation rate changes with the UPSC, the OPUC, the WPSC, the WUTC and the IPUC based on PacifiCorp's most recent depreciation study. In September 2013, the OPUC issued an order approving a multi-party stipulation to implement revised depreciation rates that will result in an annual increase in depreciation expense of $30 million in Oregon. To the extent depreciation rates for other than coal-fueled generating facilities agreed to in PacifiCorp's other state jurisdictions are lower than those approved in the Oregon order, PacifiCorp will be required to defer any excess revenue collected from Oregon customers until such time that customer rates are adjusted in a future proceeding. In Oregon, PacifiCorp is currently recovering costs associated with the Carbon Facility through 2015. In August and September 2013, PacifiCorp filed all-party stipulations with the UPSC, the WPSC and the IPUC that would result in an annual increase in depreciation expense of $10 million in Utah, $10 million in Wyoming and $2 million in Idaho, including deferrals related to the Carbon Facility. In September and October 2013, the UPSC and WPSC approved the stipulation.

23

FERC

As a result of a 2007 multi-party settlement with the FERC regarding long-term shared usage, coordinated operation and maintenance, and planning of certain 500-kV transmission lines, PacifiCorp agreed to file a Federal Power Act Section 205 rate change filing for its system-wide transmission service rates no later than June 1, 2011. In May 2011, PacifiCorp filed its Federal Power Act Section 205 rate case seeking to modify its transmission and ancillary services rates and to adopt a formula transmission rate. In August 2011, the FERC issued an order accepting PacifiCorp's filing and allowing the proposed rates to become effective December 25, 2011, subject to refund. Billing using the new rates commenced in early 2012. The FERC established settlement proceedings to encourage the parties to reach agreement on final rates. In February 2013, agreement with the parties was reached and PacifiCorp filed a settlement agreement with the FERC resolving all issues in the transmission rate case. The settlement agreement includes modifications to the formula used to determine transmission rates. The FERC approved interim rates for real power loss factors and certain ancillary services to be effective March 1, 2013 and for a new reactive power service rate to be effective May 1, 2013. In May 2013, the FERC approved PacifiCorp's settlement agreement resolving all issues for the transmission rate case. The transmission rates will continue to be updated every June according to the formula rate process.

Environmental Laws and Regulations

PacifiCorp is subject to federal, state and local laws and regulations regarding air and water quality, RPS, emissions performance standards, climate change, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact PacifiCorp's current and future operations. In addition to imposing continuing compliance obligations, these laws and regulations provide regulators with the authority to levy substantial penalties for noncompliance including fines, injunctive relief and other sanctions. These laws and regulations are administered by the EPA and various other state and local agencies. All such laws and regulations are subject to a range of interpretation, which may ultimately be resolved by the courts. Environmental laws and regulations continue to evolve, and PacifiCorp is unable to predict the impact of the changing laws and regulations on its operations and consolidated financial results. PacifiCorp believes it is in material compliance with all applicable laws and regulations. Refer to "Liquidity and Capital Resources" for discussion of PacifiCorp's forecasted environmental-related capital expenditures. The discussion below contains material developments to those matters disclosed in Item 7 of PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2012.

Clean Air Act Regulations

Regional Haze

The EPA has initiated a regional haze program intended to improve visibility in designated federally protected areas ("Class I areas"). Some of PacifiCorp's coal-fueled generating facilities in Utah, Wyoming and Arizona are subject to the Clean Air Visibility Rules. In accordance with the federal requirements, states are required to submit SIPs that address emissions from sources subject to best available retrofit technology ("BART") requirements and demonstrate progress towards achieving natural visibility requirements in Class I areas by 2064.

The state of Utah issued a regional haze SIP requiring the installation of sulfur dioxide, nitrogen oxides and particulate matter controls on Hunter Units 1 and 2, and Huntington Units 1 and 2. In December 2012, the EPA approved the sulfur dioxide portion of the Utah regional haze SIP and disapproved the nitrogen oxides and particulate matter portions. Certain groups have appealed the EPA's approval of the sulfur dioxide portion. The state of Utah and PacifiCorp filed petitions for review of the EPA's final rule on the BART determinations in Utah's regional haze SIP in March 2013. In addition, and separate from the EPA's approval process and related litigation, the Utah Division of Air Quality is undertaking an additional BART analysis for Hunter Units 1 and 2, and Huntington Units 1 and 2, which will be provided to the EPA as a supplement to the existing Utah SIP. It is unknown whether and how this supplemental analysis will impact the EPA's decision regarding the existing SIP.

24

The state of Wyoming issued two regional haze SIPs requiring the installation of sulfur dioxide, nitrogen oxides and particulate matter controls on certain PacifiCorp coal-fueled generating facilities in Wyoming. The EPA approved the sulfur dioxide SIP in December 2012, but initially proposed in June 2012 to disapprove portions of the nitrogen oxides and particulate matter SIP and instead issue a FIP. The EPA withdrew its initial proposed actions on the nitrogen oxides and particulate matter SIP and the proposed FIP, and in June 2013, published a re-proposed rule to disapprove portions of the SIP and instead issue a FIP. The EPA proposed to approve the installation of selective catalytic reduction equipment at Jim Bridger Unit 3 by December 31, 2015; to approve the installation of selective catalytic reduction equipment at Jim Bridger Unit 4 by December 31, 2016; to approve the installation of selective catalytic reduction equipment at Jim Bridger Unit 2 by December 31, 2021; to approve the installation of selective catalytic reduction equipment at Jim Bridger Unit 1 by December 31, 2022; and to approve the installation of selective catalytic reduction equipment and a baghouse at Naughton Unit 3 by December 31, 2014. However, the EPA accepted comments on PacifiCorp's planned conversion of Naughton Unit 3 to natural gas. Until the EPA approves the natural gas conversion, PacifiCorp remains under an obligation to comply with the SIP. The EPA also proposed to reject the SIP for the Wyodak facility, Naughton Units 1 and 2 and Dave Johnston Units 3 and 4; and to require within five years, the installation of selective non-catalytic reduction equipment at the Wyodak facility and Dave Johnston Unit 4, and selective catalytic reduction equipment at Naughton Units 1 and 2 and Dave Johnston Unit 3. The EPA also proposed to require the installation of low-nitrogen oxides burners and overfire air systems at Dave Johnston Units 1 and 2 by July 31, 2018. The EPA held three public hearings in June and July 2013, and the public comment period closed August 26, 2013. The EPA is under a consent decree entered into with environmental groups to take final action on its proposed action by November 2013. In the meantime, certain groups have appealed the EPA's approval of the sulfur dioxide SIP, and PacifiCorp has intervened in that appeal.

The state of Arizona issued a regional haze SIP requiring, among other things, the installation of sulfur dioxide, nitrogen oxides and particulate matter controls on Cholla Unit 4. The EPA approved in part, and disapproved in part, the Arizona SIP and issued a FIP for the disapproved portions. PacifiCorp filed an appeal in the United States Court of Appeals for the Ninth Circuit ("Ninth Circuit") regarding the FIP as it relates to Cholla Unit 4, and the Arizona Department of Environmental Quality and other affected Arizona utilities filed separate appeals of the FIP as it relates to their interests. The Ninth Circuit has not made any decisions in regard to these appeals. In April 2013, the EPA granted in part PacifiCorp's February 2013 petition for reconsideration relating to the compliance methodology for nitrogen oxides at Cholla Unit 4. The EPA plans to publish a notice of proposed rulemaking seeking comment on an alternative compliance methodology for nitrogen oxides at Cholla Unit 4, and PacifiCorp will have an opportunity to submit comments on that methodology.

A case is pending before the United States Court of Appeals for the Tenth Circuit ("Tenth Circuit") with regard to a similar appeal of a FIP issued by the EPA in New Mexico. A three-judge panel of the Tenth Circuit issued a ruling on an appeal of a FIP issued by the EPA rejecting portions of the Oklahoma SIP, denying the state's and utility's challenge. In September 2013, the state and utility filed petitions for review by the full court of the Tenth Circuit's decision in the Oklahoma case. Legal challenges of the EPA's final action on the Utah or Wyoming FIP would be filed in the Tenth Circuit. The United States Court of Appeals for the Eighth Circuit ("Eighth Circuit") recently issued a ruling on an appeal of a FIP issued by the EPA rejecting portions of the North Dakota SIP. The Eighth Circuit denied the state's and utilities' challenge in certain respects, but vacated and remanded a portion of the EPA's action relating to the EPA's refusal to take into consideration any existing pollution control technology in use at the source when it issued its FIP. PacifiCorp has raised similar concerns regarding the existing controls in use at the source to the EPA in the issuance of its Wyoming FIP and has filed comments relating to the Eighth Circuit decision with the EPA.

Until the EPA takes final action in each state and decisions have been made on each appeal, PacifiCorp cannot fully determine the impacts of the Regional Haze regulation on its generating facilities.

Climate Change

GHG Performance Standards

Under the Clean Air Act, the EPA may establish emissions standards that reflect the degree of emissions reductions achievable through the best technology that has been demonstrated, taking into consideration the cost of achieving those reductions and any non-air quality health and environmental impact and energy requirements. The EPA entered into a settlement agreement with a number of parties, including certain state governments and environmental groups, in December 2010 to promulgate emissions standards covering GHG. In April 2012, the EPA proposed new source performance standards for new fossil-fueled generating facilities that would limit emissions of carbon dioxide to 1,000 pounds per MWh. In June 2013, the President announced a national climate change strategy and issued a presidential memorandum requiring the EPA to issue a re-proposed GHG new source performance standard for fossil-fueled generating facilities by September 2013. Rather than re-propose the April 2012 proposal, the EPA issued a new proposal. The September 2013 GHG new source performance standards released by the EPA set different standards for coal-fueled and natural gas-fueled generating facilities. The proposed standard for natural gas-fueled generating facilities considers the size of the unit and the electricity sent to the grid from the unit, establishing a standard of 1,000 to 1,100 pounds of carbon dioxide per MWh. The standard proposed for coal-fueled generating facilities is 1,100 pounds of carbon dioxide per MWh on an annual basis or 1,000 to 1,050 pounds of carbon dioxide per MWh averaged over a seven-year period, both of which would require partial carbon capture and sequestration. The proposed standards have not yet been published in the Federal Register; once they are published, a 60-day public comment period will commence prior to the EPA finalizing the standard. Any new fossil-fueled generating facilities constructed by PacifiCorp will be required to meet the final GHG new source performance standards.

In addition to requiring the EPA to re-propose standards for new fossil-fueled sources, the presidential memorandum requires the EPA to propose standards or guidelines for existing and modified fossil-fueled generating facilities by June 2014, to finalize those standards or guidelines by June 2015, and to require states to submit SIPs that comply with those standards or guidelines by June 2016. The EPA has scheduled listening sessions in its regional offices during October and November 2013 to gather pre-rulemaking input into the existing source standards or guidelines and has issued a five-page framing document to gather stakeholder feedback. Until the standards or guidelines for existing, modified or reconstructed units are proposed and finalized, the impact on PacifiCorp's existing facilities cannot be determined.

Regional and State Activities

Over the past several years, the states of California, Washington and Oregon have adopted GHG emissions performance standards for base load electricity generating resources. Under the laws in California and Oregon, the emissions performance standards provide that emissions must not exceed 1,100 pounds of carbon dioxide per MWh. Effective April 2013, Washington's amended emissions performance standards provide that GHG emissions for base load electricity generating resources must not exceed 970 pounds of carbon dioxide per MWh. These GHG emissions performance standards generally prohibit electric utilities from entering into long-term financial commitments (e.g., new ownership investments, upgrades, or new or renewed contracts with a term of five or more years) unless any base load generation supplied under long-term financial commitments comply with the GHG emissions performance standards.

GHG Litigation

In October 2009, the United States District Court for the Northern District of California ("Northern District of California") granted the defendants' motions to dismiss in the case of Native Village of Kivalina v. ExxonMobil Corporation, et al. The plaintiffs filed their complaint in February 2008, asserting claims against 24 defendants, including electric generating companies, oil companies and a coal company, for public nuisance under state and federal common law based on the defendants' GHG emissions. The Northern District of California dismissed all of the plaintiffs' federal claims, holding that the court lacked subject matter jurisdiction to hear the claims under the political question doctrine, and that the plaintiffs lacked standing to bring their claims. The Northern District of California declined to hear the state law claims and the case was dismissed without prejudice to their future presentation in an appropriate state court. In November 2009, the plaintiffs appealed the case to the Ninth Circuit. In September 2012, the Ninth Circuit issued its opinion affirming the Northern District of California's dismissal of the plaintiffs' complaint. The Ninth Circuit held that the Clean Air Act displaced the plaintiffs' federal common law claims. In October 2012, the plaintiffs filed a petition for a full rehearing by the Ninth Circuit, which was denied by the Ninth Circuit in November 2012. In February 2013, the plaintiffs filed a petition with the United States Supreme Court to review the Ninth Circuit's decision. In May 2013, the United States Supreme Court denied the petition.

Collateral and Contingent Features

Debt and preferred securities of PacifiCorp are rated by credit rating agencies. Assigned credit ratings are based on each rating agency's assessment of PacifiCorp's ability to, in general, meet the obligations of its issued debt or preferred securities. The credit ratings are not a recommendation to buy, sell or hold securities, and there is no assurance that a particular credit rating will continue for any given period of time. As of September 30, 2013, PacifiCorp's credit ratings for its senior secured debt and its issuer credit ratings for senior unsecured debt from the three recognized credit rating agencies were investment grade.

PacifiCorp has no credit rating downgrade triggers that would accelerate the maturity dates of outstanding debt and a change in ratings is not an event of default under the applicable debt instruments. PacifiCorp's unsecured revolving credit facilities do not require the maintenance of a minimum credit rating level in order to draw upon their availability. However, commitment fees and interest rates under the credit facilities are tied to credit ratings and increase or decrease when the ratings change. A ratings downgrade could also increase the future cost of commercial paper, short- and long-term debt issuances or new credit facilities. Certain authorizations or exemptions by regulatory commissions for the issuance of securities are valid as long as PacifiCorp maintains investment grade ratings on senior secured debt. A downgrade below that level would necessitate new regulatory applications and approvals.

In accordance with industry practice, certain wholesale agreements, including derivative contracts, contain credit support provisions that in part base certain collateral requirements on credit ratings for senior unsecured debt as reported by one or more of the three recognized credit rating agencies. These agreements may either specifically provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features") or provide the right for counterparties to demand "adequate assurance" in the event of a material adverse change in PacifiCorp's creditworthiness. These rights can vary by contract and by counterparty. If all credit-risk-related contingent features or adequate assurance provisions for these agreements had been triggered as of September 30, 2013, PacifiCorp would have been required to post $216 million of additional collateral. PacifiCorp's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation, or other factors. Refer to Note 6 of Notes to Consolidated Financial Statements in Item 1 of this Form 10-Q for a discussion of PacifiCorp's collateral requirements specific to PacifiCorp's derivative contracts.

New Accounting Pronouncements

For a discussion of new accounting pronouncements affecting PacifiCorp, refer to Note 2 of Notes to Consolidated Financial Statements in Item 1 of this Form 10-Q.

Critical Accounting Estimates

Certain accounting measurements require management to make estimates and judgments concerning transactions that will be settled several years in the future. Amounts recognized on the Consolidated Financial Statements based on such estimates involve numerous assumptions subject to varying and potentially significant degrees of judgment and uncertainty and will likely change in the future as additional information becomes available. Estimates are used for, but not limited to, the accounting for the effects of certain types of regulation, derivatives, pension and other postretirement benefits, income taxes and revenue recognition - unbilled revenue. For additional discussion of PacifiCorp's critical accounting estimates, see Item 7 of PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2012. There have been no significant changes in PacifiCorp's assumptions regarding critical accounting estimates since December 31, 2012.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For quantitative and qualitative disclosures about market risk affecting PacifiCorp, see Item 7A of PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2012. PacifiCorp's exposure to market risk and its management of such risk has not changed materially since December 31, 2012. Refer to Note 6 of Notes to Consolidated Financial Statements in Item 1 of this Form 10-Q for disclosure of PacifiCorp's derivative positions as of September 30, 2013.

Item 4. Controls and Procedures

At the end of the period covered by this Quarterly Report on Form 10-Q, PacifiCorp carried out an evaluation, under the supervision and with the participation of PacifiCorp's management, including the Chief Executive Officer (principal executive officer) and the Chief Financial Officer (principal financial officer), of the effectiveness of the design and operation of PacifiCorp's disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended). Based upon that evaluation, PacifiCorp's management, including the Chief Executive Officer (principal executive officer) and the Chief Financial Officer (principal financial officer), concluded that PacifiCorp's disclosure controls and procedures were effective to ensure that information required to be disclosed by PacifiCorp in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and is accumulated and communicated to management, including PacifiCorp's Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. There has been no change in PacifiCorp's internal control over financial reporting during the quarter ended September 30, 2013 that has materially affected, or is reasonably likely to materially affect, PacifiCorp's internal control over financial reporting.

MINE SAFETY VIOLATIONS AND OTHER LEGAL MATTER DISCLOSURES

PURSUANT TO SECTION 1503(a) OF THE DODD-FRANK WALL STREET

REFORM AND CONSUMER PROTECTION ACT

PacifiCorp and its subsidiaries operate certain coal mines and coal processing facilities (collectively, the "mining facilities") that are regulated by the Federal Mine Safety and Health Administration ("MSHA") under the Federal Mine Safety and Health Act of 1977 (the "Mine Safety Act"). MSHA inspects PacifiCorp's mining facilities on a regular basis. The total number of reportable Mine Safety Act citations, orders, assessments and legal actions for the three-month period ended September 30, 2013 are summarized in the table below and are subject to contest and appeal. The severity and assessment of penalties may be reduced or, in some cases, dismissed through the contest and appeal process. Amounts are reported regardless of whether PacifiCorp has challenged or appealed the matter. Coal reserves that are not yet mined and mines that are closed or idled are not included in the information below as no reportable events occurred at those locations during the three-month period ended September 30, 2013. There were no mining-related fatalities during the three-month period ended September 30, 2013. PacifiCorp has not received any notice of a pattern, or notice of the potential to have a pattern, of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under Section 104(e) of the Mine Safety Act during the three-month period ended September 30, 2013.

(1) Citations for alleged violations of mandatory health and safety standards that could significantly or substantially contribute to the cause and effect of a safety or health hazard under Section 104 of the Mine Safety Act. One of the citations at Deer Creek was subsequently modified by MSHA to a non-significant and substantial citation.

(2) For alleged failure to totally abate the subject matter of a Mine Safety Act Section 104(a) citation within the period specified in the citation.

(3) For alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence) to comply with a mandatory health or safety standard.

(4) For alleged flagrant violations (i.e., reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury).

(5) For the existence of any condition or practice in a coal or other mine which could reasonably be expected to cause death or serious physical harm before such condition or practice can be abated.

(6) Amounts include 22 contests of proposed penalties under Subpart C and three labor-related complaints under Subpart E of the Federal Mine Safety and Health Review Commission's procedural rules. The pending legal actions are not exclusive to citations, notices, orders and penalties assessed by MSHA during the reporting period.

Recent Financing Transactions [Abstract]

Debt Disclosure [Text Block]

(4) Recent Financing Transactions

In June 2013, PacifiCorp issued $300 million of its 2.95% First Mortgage Bonds due June 2023. The net proceeds were used to fund capital expenditures and for general corporate purposes, including a portion of the common stock dividend paid to PPW Holdings LLC, a direct wholly owned subsidiary of MEHC and PacifiCorp's direct parent company, in June 2013.

In March 2013, PacifiCorp replaced its $630 million unsecured revolving credit facility, which had been set to expire in July 2013, with a $600 million unsecured revolving credit facility expiring in March 2018. The new credit facility, which supports PacifiCorp's commercial paper program, certain series of its tax-exempt bond obligations and provides for the issuance of letters of credit, has a variable interest rate based on the London Interbank Offered Rate or a base rate, at PacifiCorp's option, plus a spread that varies based on PacifiCorp's credit ratings for its senior unsecured long-term debt securities. As of September 30, 2013, PacifiCorp had no borrowings outstanding under this credit facility. The credit facility requires that PacifiCorp's ratio of consolidated debt, including current maturities, to total capitalization not exceed 0.65 to 1.0 as of the last day of each quarter. As of September 30, 2013, $270 million of letters of credit were issued under this credit agreement to support variable-rate tax-exempt bond obligations. These letters of credit were previously issued under the credit facility that was replaced.

In March 2013, PacifiCorp obtained $289 million of letters of credit to support variable-rate tax-exempt bond obligations. These letters of credit expire through March 2015 and replaced certain letters of credit previously issued under one of the revolving credit facilities.

As of December 31, 2012, PacifiCorp had $68 million of tax-exempt bond obligations with fixed interest rates, ranging from 3.90% to 4.13%, scheduled to reset to variable or fixed interest rates in June 2013. In June 2013, $17 million of these tax-exempt bond obligations were redeemed and retired prior to their scheduled 2014 maturity date. The interest rates for the remaining $51 million, with maturity dates ranging from 2014 to 2025, were reset to variable interest rates with a weighted average interest rate of 0.24% as of September 30, 2013.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Accounting Changes [Text Block]

(2) New Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-04, which amends FASB Accounting Standards Codification ("ASC") Topic 405, "Liabilities." The amendments in this guidance require an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the amount the reporting entity agreed to pay plus any additional amounts the reporting entity expects to pay on behalf of its co-obligor. Additionally, the guidance requires the entity to disclose the nature and amount of the obligation, as well as other information about those obligations. This guidance is effective for interim and annual reporting periods beginning after December 15, 2013. PacifiCorp is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements.

In February 2013, the FASB issued ASU No. 2013-02, which amends FASB ASC Topic 220, "Comprehensive Income." The amendments in this guidance require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required by GAAP that provide additional detail about those amounts. PacifiCorp adopted this guidance on January 1, 2013. The adoption of this guidance did not have a material impact on PacifiCorp's disclosures included within Notes to Consolidated Financial Statements.

In December 2011, the FASB issued ASU No. 2011-11, which amends FASB ASC Topic 210, "Balance Sheet." The amendments in this guidance require an entity to provide quantitative disclosures about offsetting financial instruments and derivative instruments. Additionally, this guidance requires qualitative and quantitative disclosures about master netting agreements or similar agreements when the financial instruments and derivative instruments are not offset. In January 2013, the FASB issued ASU No. 2013-01, which also amends FASB ASC Topic 210 to clarify that the scope of ASU No. 2011-11 only applies to derivative instruments, repurchase agreements, reverse purchase agreements and securities borrowing and securities lending transactions that are either being offset or are subject to an enforceable master netting arrangement or similar agreement. PacifiCorp adopted the guidance on January 1, 2013. The adoption of the guidance did not have a material impact on PacifiCorp's disclosures included within Notes to Consolidated Financial Statements.

Legal Matters

PacifiCorp is party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. PacifiCorp does not believe that such normal and routine litigation will have a material impact on its consolidated financial results. PacifiCorp is also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines, penalties and other costs in substantial amounts and are described below.

USA Power

In October 2005, prior to MEHC's ownership of PacifiCorp, PacifiCorp was added as a defendant to a lawsuit originally filed in February 2005 in the Third District Court of Salt Lake County, Utah ("Third District Court") by USA Power, LLC, USA Power Partners, LLC and Spring Canyon Energy, LLC (collectively, the "Plaintiff"). The Plaintiff's complaint alleged that PacifiCorp misappropriated confidential proprietary information in violation of Utah's Uniform Trade Secrets Act and accused PacifiCorp of breach of contract and related claims in regard to the Plaintiff's 2002 and 2003 proposals to build a natural gas-fueled generating facility in Juab County, Utah. In October 2007, the Third District Court granted PacifiCorp's motion for summary judgment on all counts and dismissed the Plaintiff's claims in their entirety. In February 2008, the Plaintiff filed a petition requesting consideration by the Utah Supreme Court. In May 2010, the Utah Supreme Court reversed summary judgment and remanded the case back to the Third District Court for further consideration, which led to a trial that began in April 2012. In May 2012, the jury reached a verdict in favor of the Plaintiff on its claims. The jury awarded damages to the Plaintiff for breach of contract and misappropriation of a trade secret in the amounts of $18 million for actual damages and $113 million for unjust enrichment. In May 2012, the Plaintiff filed a motion seeking exemplary damages. Under the Utah Uniform Trade Secrets law, the judge may award exemplary damages in an additional amount not to exceed twice the original award. The Plaintiff also filed a motion to seek recovery of attorneys' fees in an amount equal to 40% of all amounts ultimately awarded in the case. In October 2012, PacifiCorp filed post-trial motions for a judgment notwithstanding the verdict and a new trial (collectively, "PacifiCorp's post-trial motions"). The trial judge stayed briefing on the Plaintiff's motions, pending resolution of PacifiCorp's post-trial motions. As a result of a hearing in December 2012, the trial judge denied PacifiCorp's post-trial motions with the exception of reducing the aggregate amount of damages to $113 million. In January 2013, the Plaintiff filed a motion for prejudgment interest. In the first quarter of 2013, PacifiCorp filed its responses to the Plaintiff's post-trial motions for exemplary damages, attorneys' fees and prejudgment interest. An initial judgment was entered in April 2013 in which the trial judge denied the Plaintiff's motions for exemplary damages and prejudgment interest and ruled that PacifiCorp must pay the Plaintiff's attorneys' fees based on applying a reasonable rate to hours worked rather than the Plaintiff's request for an amount equal to 40% of all amounts ultimately awarded. In May 2013, a final judgment was entered against PacifiCorp in the amount of $115 million, which includes the $113 million of aggregate damages previously awarded and amounts awarded for the Plaintiff's attorneys' fees. The final judgment also ordered that postjudgment interest accrue beginning as of the date of the April 2013 initial judgment. In May 2013, PacifiCorp posted a surety bond issued by a subsidiary of Berkshire Hathaway to secure its estimated obligation. Both PacifiCorp and the Plaintiff filed appeals with the Utah Supreme Court. PacifiCorp strongly disagrees with the jury's verdict and plans to vigorously pursue all appellate measures. The appeals are awaiting a briefing schedule to be set by the Utah Supreme Court. As of September 30, 2013, PacifiCorp had accrued $116 million for the final judgment and postjudgment interest, and believes the likelihood of any additional material loss is remote; however, any additional awards against PacifiCorp could also have a material effect on the consolidated financial results. Any payment of damages will be at the end of the appeals process, which could take as long as several years.

Northwest Refund Case

In October 2011, the Federal Energy Regulatory Commission ("FERC") issued an order on remand by the United States Court of Appeals for the Ninth Circuit, in which it determined that additional procedures are needed to address possible unlawful activity that may have influenced prices in the Pacific Northwest wholesale spot market during the period from December 2000 through June 2001. PacifiCorp was a participant in the Pacific Northwest wholesale spot market during this period. The FERC ordered an evidentiary, trial-type hearing before an administrative law judge to permit parties to present evidence of alleged unlawful market activity. However, the FERC held the hearing in abeyance pending settlement discussions among all parties. The plaintiff parties to the proceeding filed claims against multiple parties, including PacifiCorp. PacifiCorp entered into settlements with the plaintiff parties, and the resulting settlements were approved by the FERC. The outcome of such settlements did not have a material impact on PacifiCorp's consolidated financial results. The FERC, however, declined to dismiss PacifiCorp from the case entirely, noting that additional parties may, in the future, assert sequential claims against parties to the case, including PacifiCorp. PacifiCorp believes it is unlikely that the FERC will address sequential claims until after the primary cases have proceeded through the trial-type hearing. Due to the uncertainties associated with the sequential claims, PacifiCorp is unable to predict the outcome and the impact of any claims on its consolidated financial results.

Environmental Laws and Regulations

PacifiCorp is subject to federal, state and local laws and regulations regarding air and water quality, renewable portfolio standards, emissions performance standards, climate change, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact PacifiCorp's current and future operations. PacifiCorp believes it is in material compliance with all applicable laws and regulations.

Purchase Obligations

In August 2013, PacifiCorp amended an existing coal supply agreement for its coal-fueled generating facilities by exercising a five-year extension period. The amended coal supply agreement results in minimum future purchases of $95 million in 2016, $96 million in 2017 and $298 million in 2018 and thereafter.

Fair Value Measurements [Abstract]

Fair Value Disclosures [Text Block]

(7) Fair Value Measurements

The carrying value of PacifiCorp's cash, certain cash equivalents, receivables, payables, accrued liabilities and short-term borrowings approximates fair value because of the short-term maturity of these instruments. PacifiCorp has various financial assets and liabilities that are measured at fair value on the Consolidated Financial Statements using inputs from the three levels of the fair value hierarchy. A financial asset or liability classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows:

• Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that PacifiCorp has the ability to access at the measurement date.

• Level 2 - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

• Level 3 - Unobservable inputs reflect PacifiCorp's judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. PacifiCorp develops these inputs based on the best information available, including its own data.

The following table presents PacifiCorp's assets and liabilities recognized on the Consolidated Balance Sheets and measured at fair value on a recurring basis (in millions):

(1) Represents netting under master netting arrangements and a net cash collateral receivable of $12 million and $55 million as of September 30, 2013 and December 31, 2012, respectively.

(2) Amounts are included in cash and cash equivalents, other current assets and other assets on the Consolidated Balance Sheets. The fair value of these money market mutual funds approximates cost.

Derivative contracts are recorded on the Consolidated Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchases or normal sales and qualify for the exception afforded by GAAP. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which PacifiCorp transacts. When quoted prices for identical contracts are not available, PacifiCorp uses forward price curves. Forward price curves represent PacifiCorp's estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates. PacifiCorp bases its forward price curves upon market price quotations, when available, or internally developed and commercial models, with internal and external fundamental data inputs. Market price quotations are obtained from independent energy brokers, exchanges, direct communication with market participants and actual transactions executed by PacifiCorp. Market price quotations for certain major electricity and natural gas trading hubs are generally readily obtainable for the first six years; therefore, PacifiCorp's forward price curves for those locations and periods reflect observable market quotes. Market price quotations for other electricity and natural gas trading hubs are not as readily obtainable for the first six years. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, PacifiCorp uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of underlying forward commodity prices, interest rates, currency rates, related volatility, counterparty creditworthiness and duration of contracts. Refer to Note 6 for further discussion regarding PacifiCorp's risk management and hedging activities.

PacifiCorp's investments in money market mutual funds are accounted for as available-for-sale securities and are stated at fair value. PacifiCorp uses a readily observable quoted market price to record the fair value.

PacifiCorp's long-term debt is carried at cost on the Consolidated Financial Statements. The fair value of PacifiCorp's long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying value of PacifiCorp's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates. The following table presents the carrying value and estimated fair value of PacifiCorp's long-term debt (in millions):

	As of September 30, 2013				As of December 31, 2012

Derivative Instruments and Hedging Activities Disclosure [Text Block]

(6)Risk Management and Hedging Activities

PacifiCorp is exposed to the impact of market fluctuations in commodity prices and interest rates. PacifiCorp is principally exposed to electricity, natural gas, coal and fuel oil commodity price risk as it has an obligation to serve retail customer load in its regulated service territories. PacifiCorp's load and generating facilities represent substantial underlying commodity positions. Exposures to commodity prices consist mainly of variations in the price of fuel required to generate electricity and wholesale electricity that is purchased and sold. Commodity prices are subject to wide price swings as supply and demand are impacted by, among many other unpredictable items, weather, market liquidity, generating facility availability, customer usage, storage, and transmission and transportation constraints. Interest rate risk exists on variable-rate debt and future debt issuances. PacifiCorp does not engage in a material amount of proprietary trading activities.

PacifiCorp has established a risk management process that is designed to identify, assess, monitor, report, manage and mitigate each of the various types of risk involved in its business. To mitigate a portion of its commodity price risk, PacifiCorp uses commodity derivative contracts, which may include forwards, options, swaps and other agreements, to effectively secure future supply or sell future production generally at fixed prices. PacifiCorp manages its interest rate risk by limiting its exposure to variable interest rates primarily through the issuance of fixed-rate long-term debt and by monitoring market changes in interest rates. Additionally, PacifiCorp may from time to time enter into interest rate derivative contracts, such as interest rate swaps or locks, to mitigate PacifiCorp's exposure to interest rate risk. No interest rate derivatives were in place during the periods presented. PacifiCorp does not hedge all of its commodity price and interest rate risks, thereby exposing the unhedged portion to changes in market prices.

There have been no significant changes in PacifiCorp's accounting policies related to derivatives. Refer to Note 7 for additional information on derivative contracts.

The following table, which reflects master netting arrangements and excludes contracts that have been designated as normal under the normal purchases or normal sales exception afforded by GAAP, summarizes the fair value of PacifiCorp's derivative contracts, on a gross basis, and reconciles those amounts to the amounts presented on a net basis on the Consolidated Balance Sheets (in millions):

Credit Risk

PacifiCorp extends unsecured credit to other utilities, energy marketing companies, financial institutions and other market participants in conjunction with its wholesale energy supply and marketing activities. Credit risk relates to the risk of loss that might occur as a result of nonperformance by counterparties on their contractual obligations to make or take delivery of electricity, natural gas or other commodities and to make financial settlements of these obligations. Credit risk may be concentrated to the extent that one or more groups of counterparties have similar economic, industry or other characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in market or other conditions. In addition, credit risk includes not only the risk that a counterparty may default due to circumstances relating directly to it, but also the risk that a counterparty may default due to circumstances involving other market participants that have a direct or indirect relationship with the counterparty.

PacifiCorp analyzes the financial condition of each significant wholesale counterparty before entering into any transactions, establishes limits on the amount of unsecured credit to be extended to each counterparty and evaluates the appropriateness of unsecured credit limits on an ongoing basis. To mitigate exposure to the financial risks of wholesale counterparties, PacifiCorp enters into netting and collateral arrangements that may include margining and cross-product netting agreements and obtains third-party guarantees, letters of credit and cash deposits. Counterparties may be assessed fees for delayed payments. If required, PacifiCorp exercises rights under these arrangements, including calling on the counterparty's credit support arrangement.

Collateral and Contingent Features

In accordance with industry practice, certain wholesale derivative contracts contain credit support provisions that in part base certain collateral requirements on credit ratings for senior unsecured debt as reported by one or more of the three recognized credit rating agencies. These derivative contracts may either specifically provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features") or provide the right for counterparties to demand "adequate assurance" in the event of a material adverse change in PacifiCorp's creditworthiness. These rights can vary by contract and by counterparty. As of September 30, 2013, PacifiCorp's credit ratings from the three recognized credit rating agencies were investment grade.

The aggregate fair value of PacifiCorp's derivative contracts in liability positions with specific credit-risk-related contingent features totaled $74 million and $153 million as of September 30, 2013 and December 31, 2012, respectively, for which PacifiCorp had posted collateral of $12 million and $56 million, respectively, in the form of cash deposits and letters of credit. If all credit-risk-related contingent features for derivative contracts in liability positions had been triggered as of September 30, 2013 and December 31, 2012, PacifiCorp would have been required to post $53 million and $73 million, respectively, of additional collateral. PacifiCorp's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation or other factors.

Fair Value, by Balance Sheet Grouping [Table Text Block]

PacifiCorp's long-term debt is carried at cost on the Consolidated Financial Statements. The fair value of PacifiCorp's long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying value of PacifiCorp's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates. The following table presents the carrying value and estimated fair value of PacifiCorp's long-term debt (in millions):
