Consolidation, Policy [Policy Text Block]

Organization and Principles of Consolidation

Effective January 1, 2019, SCANA became a wholly-owned subsidiary of Dominion Energy under the terms of the Merger Agreement. See additional discussion in Note 2 and Note 11.

The Company

SCANA, a South Carolina corporation, is a holding company created in 1984. The Company primarily engages in the generation and sale of electricity to wholesale and retail customers in South Carolina, and the purchase, sale and transportation of natural gas to wholesale and retail customers in South Carolina, North Carolina and Georgia.

The accompanying consolidated financial statements reflect the accounts of SCANA and the following wholly-owned subsidiaries.



Regulated businesses		Nonregulated businesses
South Carolina Electric & Gas Company		SCANA Energy Marketing, Inc.
South Carolina Fuel Company, Inc.		SCANA Services, Inc.
South Carolina Generating Company, Inc.		SCANA Corporate Security Services, Inc.
Public Service Company of North Carolina, Incorporated		SCANA Communications Holdings, Inc.

SCANA reports certain investments using the cost or equity method of accounting, as appropriate. Intercompany balances and transactions have been eliminated in consolidation, with the exception of profits on intercompany sales to regulated affiliates if the sales price is reasonable and the future recovery of the sales price through the rate-making process is probable, as permitted by accounting guidance. Discussions regarding the Company's financial results necessarily include the results of Consolidated SCE&G.

Consolidated SCE&G

SCE&G, a public utility, is a South Carolina corporation organized in 1924 and a wholly-owned subsidiary of SCANA. Consolidated SCE&G primarily engages in the generation and sale of electricity to wholesale and retail customers in South Carolina and in the purchase, sale and transportation of natural gas to retail customers in South Carolina.

SCE&G has determined that it has a controlling financial interest in GENCO and Fuel Company (which are considered to be VIEs) and accordingly, Consolidated SCE&G's consolidated financial statements include the accounts of SCE&G, GENCO and Fuel Company. The equity interests in GENCO and Fuel Company are held solely by SCANA, SCE&G’s parent. As a result, GENCO’s and Fuel Company’s equity and results of operations are reflected as noncontrolling interest in Consolidated SCE&G’s consolidated financial statements.

GENCO owns a coal-fired electric generating station with a 605 MW net generating capacity (summer rating). GENCO’s electricity is sold, pursuant to a FERC-approved tariff, solely to SCE&G under the terms of a power purchase agreement and related operating agreement. The effects of these transactions are eliminated in consolidation. Substantially all of GENCO’s property (carrying value of approximately $500 million) serves as collateral for its long-term borrowings. Fuel Company acquires, owns and provides financing for SCE&G’s nuclear fuel, certain fossil fuels and emission and other environmental allowances. See also Note 5.

Property, Plant and Equipment, Planned Major Maintenance Activities, Policy [Policy Text Block]

Major Maintenance

Planned major maintenance costs related to certain fossil fuel turbine equipment and nuclear refueling outages are accrued in periods other than when incurred in accordance with approval by the SCPSC for such accounting treatment and rate recovery of expenses accrued thereunder. The difference between such cumulative major maintenance costs and cumulative collections is classified as a regulatory asset or regulatory liability on the consolidated balance sheet. Other planned major maintenance is expensed when incurred.

SCE&G is authorized to collect $18.4 million annually through electric rates to offset certain turbine maintenance expenditures. For the years ended December 31, 2018, and 2017, SCE&G incurred $16.3 million and $26.1 million, respectively, for turbine maintenance.

Nuclear refueling outages are scheduled 18 months apart. As approved by the SCPSC, SCE&G accrues $17.2 million annually for its portion of the nuclear refueling outages scheduled from the spring of 2014 through the spring of 2020. Refueling outage costs incurred for which SCE&G was responsible totaled

Nuclear Decommissiong [Policy Text Block]

Nuclear Decommissioning

Based on a decommissioning cost study, SCE&G’s two-thirds share of estimated site-specific nuclear decommissioning costs for Unit 1, including the cost of decommissioning plant components both subject to and not subject to radioactive contamination, totals $625.8 million, stated in 2018 dollars. Santee Cooper is responsible for decommissioning costs related to its one-third ownership interest in Unit 1. The cost estimate assumes that the site will be maintained over a period of approximately 60 years in such a manner as to allow for subsequent decontamination that would permit release for unrestricted use.

Under SCE&G’s method of funding decommissioning costs, SCE&G transfers to an external trust fund the amounts collected through rates ($3.2 million pre-tax in each period presented), less expenses. The trust invests the amounts transferred into insurance policies on the lives of certain company personnel. Insurance proceeds are reinvested in insurance policies. The asset balance held in trust reflects the net cash surrender value of the insurance policies and cash held by the trust. Management intends for the fund, including earnings thereon, to provide for all eventual decommissioning expenditures for Unit 1 on an after-tax basis.

Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]

Receivables

Customer receivables reflect amounts due from customers arising from the delivery of energy or related services and include both billed and unbilled amounts earned pursuant to revenue recognition practices described in Note 3. Customer receivables are generally due within one month of receipt of invoices which are presented on a monthly cycle basis. Unbilled revenues totaled $217.5 million at December 31, 2018 and $220.9 million at December 31, 2017 for the Company. Unbilled revenues totaled $129.3 million at December 31, 2018 and $140.3 million at December 31, 2017 for Consolidated SCE&G.

Other receivables consist primarily of amounts due from Santee Cooper related to the jointly owned nuclear generating facilities at Summer Station.

Asset Management and Supply Service Agreements [Policy Text Block]

PSNC Energy, a subsidiary of SCANA, utilizes an asset management and supply service agreement with a counterparty for certain natural gas storage facilities. Such counterparty held, through an agency relationship, 46% and 39% of PSNC Energy’s natural gas inventory at December 31, 2018 and December 31, 2017, respectively, with a carrying value of $13.9 million and $11.5 million, respectively. Under the terms of this agreement, PSNC Energy receives storage asset management fees of which 75% are credited to customers. This agreement has been extended and expires October 31, 2020.

regulatory assets and regulatory liabilities [Policy Text Block]

Regulatory Assets and Regulatory Liabilities

The Company’s rate-regulated utilities, including Consolidated SCE&G, record costs that have been or are expected to be allowed in the ratemaking process in periods that differ from those in which the costs would be charged to expense, or record revenues in periods that differ from those in which the revenues would be recorded, by a nonregulated enterprise. These expenses deferred for future recovery from customers or obligations for refunds to customers are primarily classified on the balance sheet as regulatory assets and regulatory liabilities (see Note 2) and are amortized consistent with the treatment of the related costs or revenues in the ratemaking process. Certain deferred amounts expected to be recovered or repaid within 12 months are classified on the balance sheet as Receivables - Customer or Customer deposits and customer prepayments, respectively.

Environmental Costs, Policy [Policy Text Block]

Environmental

An environmental assessment program is maintained to identify and evaluate current and former operations sites that could require environmental clean-up. As site assessments are initiated, estimates are made of the amount of expenditures, if any, deemed necessary to investigate and remediate each site. Environmental remediation liabilities are accrued when the criteria for loss contingencies are met. These estimates are refined as additional information becomes available; therefore, actual expenditures could differ significantly from the original estimates. Probable and estimable costs are accrued related to environmental sites on an undiscounted basis. Amounts estimated and accrued to date for site assessments and clean-up relate solely to regulated operations. Amounts expected to be recovered through rates are recorded in regulatory assets and, if applicable, amortized over approved amortization periods. Other environmental costs are expensed as incurred.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

Revenues are recorded during the accounting period in which services are provided to customers and include estimated amounts for electricity and natural gas delivered but not billed.

Fuel costs, emission allowances and certain environmental reagent costs for electric generation are collected through the fuel cost component in retail electric rates. The SCPSC establishes this component during fuel cost proceedings. Any difference between actual fuel costs and amounts contained in the fuel cost component is adjusted through revenue and is deferred and included when determining the fuel cost component during subsequent proceedings.

SCE&G customers subject to a PGA are billed based on a cost of gas factor calculated in accordance with a gas cost recovery procedure approved by the SCPSC and subject to adjustment monthly. Any difference between actual gas costs and amounts contained in rates is adjusted through revenue and is deferred and included when making the next adjustment to the cost of gas factor. PSNC Energy’s PGA mechanism authorized by the NCUC allows the recovery of all prudently incurred gas costs, including the results of its hedging program, from customers. Any difference between actual gas costs and amounts contained in rates is deferred and included when establishing gas costs during subsequent PGA filings or in annual prudence reviews.

Taxes billed to and collected from customers are recorded as liabilities until they are remitted to the respective taxing authority. Such taxes are not included in revenues or expenses in the statements of operations.

New Accounting Matters [Policy Text Block]

New Accounting Matters

Recently Adopted

In the first quarter of 2018, the Company and Consolidated SCE&G adopted the following accounting guidance, as applicable, issued by the FASB. The adoption of this guidance had no impact or no significant impact on their respective financial statements except as indicated.


•	Goodwill impairment guidance, issued in January 2017, removed Step 2 of the goodwill impairment test.

•

Guidance for revenue arising from contracts with customers uses a five-step analysis in determining when and how revenue is recognized, and requires that revenue recognition depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. As permitted, this guidance was adopted using the modified retrospective method whereby amounts and disclosures for prior periods were not restated. Revenue recognition patterns did not change as a result of adopting this guidance, and no cumulative effect adjustment to Retained Earnings was required. For additional required disclosures, see Note 3.

•

The required presentation of net periodic pension and postretirement benefit costs has been changed to distinguish between service cost components and non-service cost components. Service cost components continue to be included within operating income and are presented in the same line item as other compensation costs arising from services rendered by employees. Non-service cost components are now excluded from operating income. This guidance has been applied retrospectively for the presentation of the service cost components and other components, and resulted in the following changes to amounts reported in 2017 and 2016.



Increase (Decrease) Millions of dollars	The Company						Consolidated SCE&G
Year Ended December 31	2017			2016			2017			2016
Other operation and maintenance	$	(9	)	$	(14	)	$	(7	)	$	(12	)
Total Operating Expenses	(9		)	(14		)	(7		)	(12		)
Operating Income	9			14			7			12
Other Income (Expense), Net	(9		)	(14		)	(7		)	(12		)

In addition, this guidance limits eligibility for capitalization of net periodic pension and postretirement benefit costs to only the service cost component, and requires this change to be applied prospectively. Accordingly, no reclassifications were made related to the capitalization of service costs. Effective January 1, 2018, amounts which otherwise would have been capitalized to plant accounts under prior guidance are now being deferred within regulatory assets.


•	Guidance issued in January 2016 changed how entities measure certain equity investments and financial liabilities, among other things.


•	Guidance issued in August 2016 is intended to reduce diversity in cash flow statement classification related to certain transactions, and entities must apply the guidance retrospectively to all periods presented.


•	Guidance issued in November 2016 clarified how restricted cash should be presented on the statement of cash flows, and entities were to apply the guidance retrospectively to all periods presented.

Pending Adoption

The Company and Consolidated SCE&G will adopt the following accounting guidance issued by the FASB when indicated below.

In February 2016, the FASB issued revised accounting guidance for the recognition, measurement, presentation and disclosure of leasing arrangements. The update requires that a liability and corresponding right-of-use asset are recorded on the balance sheet for all leases, including those leases currently classified as operating leases, while also refining the definition of a lease. In addition lessees will be required to disclose key information about the amount, timing, and uncertainty of cash flows arising from leasing arrangements. Lessor accounting remains largely unchanged.

The guidance is effective for the Company's and Consolidated SCE&G's interim and annual reporting periods beginning January 1, 2019. This revised accounting guidance will be adopted using a modified-retrospective approach, which requires lessees and lessors to recognize and measure leases at the date of adoption. Under this approach, the Company and Consolidated SCE&G are permitted to utilize the transition practical expedient to maintain historical presentation for periods before January 1, 2019. The Company and Consolidated SCE&G will apply the other practical expedients, which would require no reassessment of whether existing contracts are or contain leases, no reassessment of lease classification for existing leases and no reassessment of existing or expired land easements that were not previously accounted for as leases. The Company and Consolidated SCE&G anticipate that the adoption of this guidance will result in approximately $30 million to $35 million and $15 million to $20 million, respectively, of offsetting right-of-use assets and liabilities added to their consolidated balance sheets for operating leases in effect at the adoption date. No material changes are expected to the Company's and Consolidated SCE&G's results of operations.

In August 2017, the FASB issued accounting guidance intended to simplify the application of hedge accounting. Among other things, the new guidance will enable more hedging strategies to qualify for hedge accounting, will allow entities more time to perform an initial assessment of hedge effectiveness, and will permit an entity to perform a qualitative assessment of effectiveness for certain hedges instead of a quantitative one. For cash flow hedges that are highly effective, all changes in the fair value of the derivative hedging instrument will be recorded in other comprehensive income and will be reclassified to earnings in the same period that the hedged item impacts earnings. Fair value hedges will continue to be recorded in current earnings, and any ineffectiveness will impact the income statement. In addition, changes in the fair value of a derivative will be recorded in the same income statement line as the earnings effect of the hedged item, and additional disclosures will be required related to the effect of hedging on individual income statement line items. The guidance must be applied to all outstanding instruments using a modified retrospective method, with any cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. The Company and Consolidated SCE&G will adopt this guidance when required in the first quarter of 2019 and do not expect it to have a significant impact on their respective financial statements.

In February 2018, the FASB issued accounting guidance allowing entities to reclassify from AOCI to retained earnings any amounts for stranded tax effects resulting from the Tax Act. The guidance must be applied either in the period of adoption or retrospectively to each period in which the effect of the change was recognized. The Company and Consolidated SCE&G will adopt this guidance when required in the first quarter of 2019 on a prospective basis. Upon adoption, the Company and Consolidated SCE&G expect to record cumulative effect adjustments to retained earnings and AOCI in their statements of changes in common equity (in the amount of $8 million and $1 million at the Company and Consolidated SCE&G, respectively) and do not expect any other significant impact on their financial statements. The amounts to be reclassified reflect the impact of the reduction in the federal income tax rate arising from the Tax Act, and the related federal benefit of state income taxes, on the components of the Company’s and Consolidated SCE&G’s AOCI.

In June 2016, the FASB issued accounting guidance requiring the use of a current expected credit loss impairment model for certain financial instruments. The new model is applicable to trade receivables and most debt instruments, among other financial instruments, and in certain instances may result in impairment losses being recognized earlier than under current guidance. The Company and Consolidated SCE&G must adopt this guidance beginning in 2020, including interim periods, though the guidance may be adopted in 2019. A modified-retrospective approach is required upon adoption, whereby a cumulative-effect adjustment to retained earnings is made as of the beginning of the first reporting period in which the guidance is effective. The Company and Consolidated SCE&G have not determined when this guidance will be adopted or what impact it will have on their respective financial statements.

In August 2018, the FASB issued accounting guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance must be applied retrospectively to all periods presented. The Company and Consolidated SCE&G must adopt this guidance beginning in 2020, including interim periods, though the guidance may be adopted earlier. The Company and Consolidated SCE&G have not determined when this guidance will be adopted or what impact it will have on their respective statements of financial position.

Significant Accounting Policies

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Nuclear Decommissiong [Policy Text Block]

Nuclear Decommissioning

Based on a decommissioning cost study, SCE&G’s two-thirds share of estimated site-specific nuclear decommissioning costs for Unit 1, including the cost of decommissioning plant components both subject to and not subject to radioactive contamination, totals $625.8 million, stated in 2018 dollars. Santee Cooper is responsible for decommissioning costs related to its one-third ownership interest in Unit 1. The cost estimate assumes that the site will be maintained over a period of approximately 60 years in such a manner as to allow for subsequent decontamination that would permit release for unrestricted use.

Management intends for the fund, including earnings thereon, to provide for all eventual decommissioning expenditures for Unit 1 on an after-tax basis.

Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]

Receivables

Customer receivables reflect amounts due from customers arising from the delivery of energy or related services and include both billed and unbilled amounts earned pursuant to revenue recognition practices described in Note 3. Customer receivables are generally due within one month of receipt of invoices which are presented on a monthly cycle basis. Unbilled revenues totaled $217.5 million at December 31, 2018 and $220.9 million at December 31, 2017 for the Company. Unbilled revenues totaled $129.3 million at December 31, 2018 and $140.3 million at December 31, 2017 for Consolidated SCE&G.

Other receivables consist primarily of amounts due from Santee Cooper related to the jointly owned nuclear generating facilities at Summer Station.

Income Tax, Policy [Policy Text Block]

Income Taxes

SCANA files consolidated federal income tax returns. Under a joint consolidated income tax allocation agreement, each subsidiary’s current and deferred tax expense is computed on a stand-alone basis. Deferred tax assets and liabilities are recorded for the tax effects of all significant temporary differences between the book basis and tax basis of assets and liabilities at currently enacted tax rates. Deferred tax assets and liabilities are adjusted for changes in such tax rates through charges or credits to regulatory assets or liabilities if such impacts are expected to be recovered from, or passed through to, customers of the Company’s regulated subsidiaries; otherwise, such adjustments are charged or credited to deferred income tax expense. Also, see Note 6 for a discussion of the impact of adjustments recorded in connection with enactment of the Tax Act.

Consolidated SCE&G is included in the consolidated federal income tax returns of SCANA for all periods presented. Also, under provisions of an income tax allocation agreement, certain tax benefits of the parent holding company are distributed in cash to tax paying affiliates, including Consolidated SCE&G, in the form of capital contributions.

Debt Premium, Discount, and Expense [Policy Text Block]

Debt Issuance Premiums, Discounts and Other Costs

Premiums, discounts and debt issuance costs are presented within long-term debt and are amortized as components of interest charges over the terms of the respective debt issues. For regulated subsidiaries, gains or losses on reacquired debt that is refinanced are recorded in other deferred credits or debits and are amortized over the term of the replacement debt, also as interest charges.

Income Statement policy [Policy Text Block]

Statement of Operations Presentation

Revenues and expenses arising from regulated businesses and, in the case of the Company, the retail natural gas marketing business (including those activities of segments described in Note 12) are presented within Operating Income (Loss), and all other activities are presented within Other Income (Expense).
