10. Commitments and Contingencies

 

Energy Purchase Commitments

 

(PPL, LKE, LG&E and KU)

 

Pursuant to a power purchase agreement with OVEC, extended in February 2011 to 2040, pending KPSC and VSCC approvals, LG&E and KU are conditionally responsible for their pro-rata share of certain obligations of OVEC under defined circumstances. These contingent liabilities may include unpaid OVEC indebtedness as well as shortfall amounts in certain excess decommissioning costs and other post-employment benefit costs. LKE's contingent proportionate share of OVEC's outstanding debt was $111 million at June 30, 2011, consisting of LG&E's share of $77 million and KU's share of $34 million.

(PPL and PPL Electric)

 

In 2009, the PUC approved PPL Electric's procurement plan for the period January 2011 through May 2013. Through July 2011, PPL Electric has conducted eight of its 14 planned competitive solicitations. The solicitations include a mix of long-term and short-term purchases ranging from five months to ten years to fulfill PPL Electric's obligation to provide for customer supply as a PLR. See Note 6 for a discussion of the default service supply procurement provisions of Act 129.

Legal Matters

 

(PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

PPL and its subsidiaries are involved in legal proceedings, claims and litigation in the ordinary course of business.

 

(PPL, LKE, LG&E and KU)

 

Trimble County Unit 2 Construction

 

In June 2006, LG&E and KU entered into a construction contract regarding the TC2 project. The contract is generally in the form of a turnkey agreement for the design, engineering, procurement, construction, commissioning, testing and delivery of the project, according to designated specifications, terms and conditions. The contract price and its components are subject to a number of potential adjustments which may serve to increase or decrease the ultimate construction price. During 2009 and 2010, LG&E and KU received several contractual notices from the TC2 construction contractor asserting historical force majeure and excusable event claims for a number of adjustments to the contract price, construction schedule, commercial operations date, liquidated damages or other relevant provisions. In September 2010, LG&E, KU and the construction contractor agreed to a settlement to resolve the force majeure and excusable event claims occurring through July 2010, under the TC2 construction contract, which settlement provided for a limited, negotiated extension of the contractual commercial operations date and/or relief from liquidated damage calculations. With limited exceptions, LG&E and KU took care, custody and control of TC2 in January 2011. LG&E and KU and the contractor have agreed to certain amendments to the construction agreement whereby the contractor will complete certain actions relating to identifying and completing any necessary modifications to allow operation of TC2 on all fuels in accordance with initial specifications prior to certain dates, and amending the provisions relating to liquidated damages. The remaining issues are still under discussion with the contractor. PPL, LKE, LG&E and KU cannot currently predict the outcome of this matter or the potential impact on the capital costs of this project.

 

Trimble County Unit 2 Transmission

 

LG&E's and KU's Certificate of Public Convenience and Necessity (CCN) and condemnation rights relating to a transmission line associated with the TC2 construction have been challenged by certain property owners in Hardin County, Kentucky. Certain proceedings relating to CCN challenges and federal historic preservation permit requirements have concluded with outcomes in LG&E's and KU's favor. With respect to the remaining issues in dispute, during 2008 KU obtained various successful rulings at the Hardin County Circuit Court confirming its condemnation rights. In August 2008, several landowners appealed such rulings to the Kentucky Court of Appeals. In May 2010, the Kentucky Court of Appeals issued an Order affirming the Hardin Circuit Court's finding that KU had the right to condemn easements on the properties. In May 2010, the landowners filed a petition for reconsideration with the Kentucky Court of Appeals. In July 2010, the Kentucky Court of Appeals denied that petition. In August 2010, the landowners filed for discretionary review of that denial by the Kentucky Supreme Court. In March 2011, the Kentucky Supreme Court issued an order declining the discretionary review request, thus closing this matter.

 

Argentina Matters (LKE, LG&E and KU)

 

In connection with an administrative proceeding alleging a violation by a former Argentine subsidiary under that country's 2002-2003 emergency currency exchange laws, claims were brought against the subsidiary's then directors, including two individuals who are executive officers of LKE, in a specialized Argentine financial criminal court. Under applicable Argentine laws, directors of a local company may be liable for monetary penalties for a subject company's violations of the currency laws. In February 2011, the Argentine court issued an order acquitting the former subsidiary and its directors of all claims, which order has become final.

 

(PPL and PPL Energy Supply)

 

Spent Nuclear Fuel Litigation

 

Federal law requires the U.S. government to provide for the permanent disposal of commercial spent nuclear fuel, but there is no definitive date by which a repository will be operational. As a result, it was necessary to expand Susquehanna's on-site spent fuel storage capacity. To support this expansion, PPL Susquehanna contracted for the design and construction of a spent fuel storage facility employing dry cask fuel storage technology. The facility is modular, so that additional storage capacity can be added as needed. The facility began receiving spent nuclear fuel in 1999. PPL Susquehanna estimates that there is sufficient storage capacity in the spent nuclear fuel pools and the on-site dry cask storage facility at Susquehanna to accommodate spent fuel discharged through approximately 2017 under current operating conditions. If necessary, on-site dry cask storage capability can be expanded, assuming appropriate regulatory approvals are obtained, such that, together, the spent fuel pools and the expanded dry fuel storage facilities will accommodate all of the spent fuel expected to be discharged through the current licensed life of each unit, 2042 for Unit 1 and 2044 for Unit 2.

 

In 1996, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) ruled that the Nuclear Waste Policy Act imposed on the DOE an unconditional obligation to begin accepting spent nuclear fuel on or before January 31, 1998. In 1997, the D.C. Circuit Court ruled that the contracts between the utilities and the DOE provide a potentially adequate remedy if the DOE failed to begin accepting spent nuclear fuel by January 31, 1998. The DOE did not, in fact, begin to accept spent nuclear fuel by that date. The DOE continues to contest claims that its breach of contract resulted in recoverable damages. In January 2004, PPL Susquehanna filed suit in the U.S. Court of Federal Claims for unspecified damages suffered as a result of the DOE's breach of its contract to accept and dispose of spent nuclear fuel. In May 2011, the parties entered into a settlement agreement which resolved all claims of PPL Susquehanna through December 2013. Under the settlement agreement, PPL Susquehanna received approximately $50 million for its share of claims to recover costs to store spent nuclear fuel at the Susquehanna station through September 30, 2009, and will be eligible to receive payment of annual claims for allowed costs, as set forth in the settlement agreement, that are incurred thereafter through the December 31, 2013 termination date of the settlement agreement. In exchange, PPL Susquehanna has waived any claims against the United States government for costs paid or injuries sustained related to storing spent nuclear fuel at PPL Susquehanna through December 31, 2013.

 

Montana Hydroelectric Litigation

 

In November 2004, PPL Montana, Avista Corporation (Avista) and PacifiCorp commenced an action for declaratory judgment in Montana First Judicial District Court seeking a determination that no lease payments or other compensation for their hydroelectric facilities' use and occupancy of certain riverbeds in Montana can be collected by the State of Montana. This lawsuit followed dismissal on jurisdictional grounds of an earlier federal lawsuit seeking such compensation in the U.S. District Court of Montana. The federal lawsuit alleged that the beds of Montana's navigable rivers became state-owned trust property upon Montana's admission to statehood, and that the use of them should, under a 1931 regulatory scheme enacted after all but one of the hydroelectric facilities in question were constructed, trigger lease payments for use of land beneath. In July 2006, the Montana state court approved a stipulation by the State of Montana that it was not seeking compensation for the period prior to PPL Montana's December 1999 acquisition of the hydroelectric facilities.

 

Following a number of adverse trial court rulings, in 2007 Pacificorp and Avista each entered into settlement agreements with the State of Montana providing, in pertinent part, that each company would make prospective lease payments for use of the State's navigable riverbeds (subject to certain future adjustments), resolving the State's claims for past and future compensation.

 

Following an October 2007 trial of this matter on damages, in June 2008, the Montana District Court awarded the State retroactive compensation of approximately $35 million for the 2000-2006 period and approximately $6 million for 2007 compensation. Those unpaid amounts continue to accrue interest at 10% per year. The Montana District Court also deferred determination of compensation for 2008 and future years to the Montana State Land Board. In October 2008, PPL Montana appealed the decision to the Montana Supreme Court, requesting a stay of judgment and a stay of the Land Board's authority to assess compensation for 2008 and future periods.

 

In March 2010, the Montana Supreme Court substantially affirmed the June 2008 Montana District Court decision. As a result, in the first quarter of 2010, PPL Montana recorded a pre-tax charge of $56 million ($34 million after tax or $0.08 per share, basic and diluted, for PPL), representing estimated rental compensation for the first quarter of 2010 and prior years, including interest. Rental compensation was estimated for periods subsequent to 2007, although such estimated amounts may differ from amounts ultimately determined by the Montana State Land Board. The portion of the pre-tax charge that related to prior years totaled $54 million ($32 million after tax). The pre-tax charge recorded on the Statement of Income was $49 million in "Other operation and maintenance" and $7 million in "Interest Expense." PPL Montana continues to accrue interest expense for the prior years and rent expense for the current year. PPL Montana's total loss accrual at June 30, 2011 was $81 million.

 

In August 2010, PPL Montana filed a petition for a writ of certiorari with the U.S. Supreme Court requesting the Court's review of this matter. In June 2011, the Supreme Court granted PPL Montana's petition. This matter will be briefed on its merits, with oral argument likely to occur in late November or early December 2011 and a decision likely to be rendered by the Court by June 30, 2012. The stay of the judgment granted during the proceedings before the Montana Supreme Court has been extended by agreement with the State of Montana, to cover the anticipated period of the proceeding before the U.S. Supreme Court. PPL and PPL Energy Supply cannot predict the outcome of this matter, but do not expect to incur material losses beyond the estimated losses recorded.

 

PJM/MISO Billing Dispute (PPL, PPL Energy Supply and PPL Electric)

 

In 2009, PJM reported that it had discovered a modeling error in the market-to-market power flow calculations between PJM and MISO. The error was a result of incorrect modeling of certain generation resources that have an impact on power flows across the PJM/MISO border. Informal settlement discussions on this issue terminated in March 2010. Also in March 2010, MISO filed two complaints with the FERC concerning the modeling error and related matters with a demand for $130 million of principal plus interest. In April 2010, PJM filed answers to the complaints and filed a related complaint against MISO. In its answers and complaint, PJM denies that any compensation is due to MISO and seeks recovery in excess of $25 million from MISO for alleged violations by MISO regarding market-to-market power flow calculations. PPL participates in markets in both PJM and MISO. In June 2010, the FERC ordered the complaints to be consolidated and set for settlement discussions, followed by hearings if the discussions are unsuccessful. In January 2011, the parties to this dispute filed a settlement with the FERC under which no compensation would be paid to either PJM or MISO and providing for certain improvements in how the calculations are administered going forward. The settlement was contested by several parties and in June 2011 the FERC issued an order approving the contested settlement, which order has become final and is not subject to rehearing and appeal.

 

Regulatory Issues (PPL, PPL Electric, LKE, LG&E and KU)

 

See Note 6 for information on regulatory matters related to utility rate regulation.

 

Enactment of Financial Reform Legislation (PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

In July 2010, the Dodd-Frank Act was signed into law. Of particular relevance to PPL and PPL Energy Supply, the Dodd-Frank Act includes provisions that will likely impose derivative transaction reporting requirements and will require most over-the-counter derivative transactions to be executed through an exchange or to be centrally cleared. The Dodd-Frank Act, however, provides an exemption from mandatory clearing and exchange trading requirements for over-the-counter derivative transactions used to hedge or mitigate commercial risk. Although the phrase "to hedge or mitigate commercial risk" is not defined in the Dodd-Frank Act, the 2010 rules proposed by the Commodity Futures Trading Commission (CFTC) set forth an inclusive, multi-pronged definition for the phrase. Based on this proposed definition and other requirements in the proposed rule, it is anticipated that transactions utilized by PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU should qualify if they are not entered into for speculative purposes. The Dodd-Frank Act also provides that the CFTC may impose collateral and margin requirements for over-the-counter derivative transactions, including those that are used to hedge commercial risk. However, during drafting of the Dodd-Frank Act, certain members of Congress adopted report language and issued a public letter stating that it was not their intention to impose margin and collateral requirements on counterparties that utilize these transactions to hedge commercial risk. Final rules on major provisions in the Dodd-Frank Act, including imposition of collateral and margin requirements, will be established through rulemakings and the CFTC has postponed implementation until December 31, 2011. PPL and PPL Energy Supply may be required to post additional collateral if they are subject to margin requirements as ultimately adopted in the implementing regulations of the Dodd-Frank Act. PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU will continue to evaluate the provisions of the Dodd-Frank Act and monitor developments related to its implementation. At this time, PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU cannot predict the impact that the new law or its implementing regulations will have on their businesses or operations, or the markets in which they transact business, but currently do not expect to incur material costs related to this matter.

 

New Jersey Capacity Legislation (PPL, PPL Energy Supply and PPL Electric)

 

In January 2011, New Jersey enacted a law that intervenes in the wholesale capacity market exclusively regulated by the FERC: S. No. 2381, 214th Leg. (N.J. 2011) (the Act). To create incentives for the development of new, in-state electric generation facilities, the Act implements a "long-term capacity agreement pilot program (LCAPP)." The Act requires New Jersey utilities to pay a guaranteed fixed price for wholesale capacity, imposed by the New Jersey Board of Public Utilities (BPU), to certain new generators participating in PJM, with the ultimate costs of that guarantee to be borne by New Jersey ratepayers. PPL believes the intent and effect of the LCAPP is to encourage the construction of new generation in New Jersey even when, under the FERC-approved PJM economic model, such new generation would not be economic. The Act could depress capacity prices in PJM in the short term, impacting PPL Energy Supply's revenues, and harm the long-term ability of the PJM capacity market to incent necessary generation investment throughout PJM. In February 2011, the PJM Power Providers Group (P3), an organization in which PPL is a member, filed a complaint before the FERC seeking changes in PJM's capacity market rules designed to ensure that subsidized generation, such as may result from the implementation of the LCAPP, will not be able to set capacity prices artificially low as a result of their exercise of buyer market power. In April 2011, the FERC issued an order granting in part and denying in part P3's complaint and ordering changes in PJM's capacity rules consistent with a significant portion of P3's requested changes. PPL, PPL Energy Supply and PPL Electric cannot predict the outcome of this proceeding or the economic impact on their businesses or operations, or the markets in which they transact business.

 

In addition, in February 2011, PPL, with several other generating companies and utilities, filed a complaint in Federal Court in New Jersey challenging the Act on the grounds that it violates well-established principles under the Supremacy Clause and the Commerce Clause of the U.S. Constitution. In this action, the Plaintiffs request declaratory and injunctive relief barring implementation of the Act by the Commissioners of the BPU. PPL, PPL Energy Supply and PPL Electric cannot predict the outcome of this proceeding or the economic impact on their businesses or operations, or the markets in which they transact business.

 

California ISO and Western U.S. Markets (PPL and PPL Energy Supply)

 

Through its subsidiaries, PPL Energy Supply made $18 million of sales to the California ISO during the period October 2000 through June 2001, $17 million of which has not been paid to PPL subsidiaries. Also, there has been further litigation about additional claims of refunds for periods prior to October 2000. In January 2011, PPL and the "California Parties" (collectively, three California utility companies, the California Public Utility Commission and certain California state authorities) filed a settlement under which PPL would receive approximately $1 million of its $17 million claim, plus interest of $1 million. In June 2011, the FERC approved the settlement; therefore PPL released its reserve and wrote-off the related receivable. Settlement proceeds were received in July.

 

In June 2003, the FERC took several actions as a result of several related investigations beyond the California ISO litigation. The FERC terminated proceedings to consider whether to order refunds for spot market bilateral sales made in the Pacific Northwest, including sales made by PPL Montana, during the period December 2000 through June 2001. In August 2007, the U.S. Court of Appeals for the Ninth Circuit reversed the FERC's decision and ordered the FERC to consider additional evidence. The FERC also commenced additional investigations relating to "gaming" and bidding practices during 2000 and 2001, but neither PPL EnergyPlus nor PPL Montana believes it is a subject of these investigations.

 

Although PPL and its subsidiaries believe that they have not engaged in any improper trading or marketing practices affecting the western markets, PPL and PPL Energy Supply cannot predict the outcome of the above-described investigations, lawsuits and proceedings or whether any subsidiaries will be the subject of any additional governmental investigations or named in other lawsuits or refund proceedings. Consequently, PPL and PPL Energy Supply cannot estimate a range of reasonably possible losses, if any, related to these matters.

 

PJM RPM Litigation (PPL, PPL Energy Supply and PPL Electric)

 

In May 2008, a group of state public utility commissions, state consumer advocates, municipal entities and electric cooperatives, industrial end-use customers and a single electric distribution company (collectively, the RPM Buyers) filed a complaint before the FERC objecting to the prices for capacity under the PJM Reliability Pricing Model (RPM) that were set in the 2008-09, 2009-10 and 2010-11 RPM base residual auctions. The RPM Buyers requested that the FERC reset the rates paid to generators for capacity in those periods to a significantly lower level. Thus, the complaint requests that generators be paid less for those periods through refunds and/or prospective changes in rates. The relief requested in the complaint, if granted, could have a material effect on PPL, PPL Energy Supply and PPL Electric. PJM, PPL and numerous other parties responded to the complaint, strongly opposing the relief sought by the RPM Buyers. In September 2008, the FERC entered an order denying the complaint. In August 2009, the RPM Buyers appealed the FERC's decision to the U.S. Court of Appeals for the Fourth Circuit, and the appeal was subsequently transferred to the U.S. Court of Appeals for the District of Columbia Circuit. In February 2011, the U.S. Court of Appeals for the District of Columbia Circuit issued an order denying the appeal. No party sought review of the order denying the appeal. FERC's September 2008 denial of the complaint is therefore final.

 

In December 2008, PJM submitted amendments to certain provisions governing its RPM capacity market. The amendments were intended to permit the compensation available to suppliers that provide capacity, including PPL Energy Supply, to increase. PJM sought approval of the amendments in time for them to be implemented for the May 2009 capacity auction (for service in June 2012 through May 2013). Numerous parties, including PPL, protested PJM's filing. Certain of the protesting parties, other than PPL, proposed changes to the capacity market auction that would result in a reduction in compensation to capacity suppliers. The changes proposed by PJM and by other parties in response to PJM proposals could significantly affect the compensation available to suppliers of capacity participating in future RPM auctions. In March 2009, the FERC entered an order approving in part and disapproving in part the changes proposed by PJM. In August 2009, the FERC issued an order granting rehearing in part, denying rehearing in part and clarifying its March 2009 order. No request for rehearing or appeal of the August 2009 order was timely filed. In October 2010, the August 2009 Order became final and will not have a material impact on PPL, PPL Energy Supply or PPL Electric.

 

FERC Market-Based Rate Authority (PPL, PPL Energy Supply, LKE, LG&E and KU)

 

In December 1998, the FERC authorized PPL EnergyPlus to make wholesale sales of electric power and related products at market-based rates. In that order, the FERC directed PPL EnergyPlus to file an updated market analysis within three years after the order, and every three years thereafter. Since then, periodic market-based rate filings with the FERC have been made by PPL EnergyPlus, PPL Electric, PPL Montana and most of PPL Generation's subsidiaries. These filings consisted of a Northwest market-based rate filing for PPL Montana and a Northeast market-based rate filing for most of the other PPL subsidiaries in PJM's region. In December 2010, PPL filed its market-based rate update for the Eastern region. In January 2011, PPL filed the market-based rate update for the Western region. In June 2011, PPL filed its market-based rate update for the Southeast region, including LG&E and KU in addition to PPL EnergyPlus. In June 2011, the FERC issued an order approving LG&E's and KU's request for a determination that they no longer be deemed to have market power in the Big Rivers Electric Corporation balancing area and removing restrictions on their market-based rate authority in such region.

 

Currently, a seller granted market-based rate authority by the FERC may enter into power contracts during an authorized time period. If the FERC determines that the market is not workably competitive or that the seller possesses market power or is not charging "just and reasonable" rates, it may institute prospective action, but any contracts entered into pursuant to the FERC's market-based rate authority remain in effect and are generally subject to a high standard of review before the FERC can order changes. Recent court decisions by the U.S. Court of Appeals for the Ninth Circuit have raised issues that may make it more difficult for the FERC to continue its program of promoting wholesale electricity competition through market-based rate authority. These court decisions permit retroactive refunds and a lower standard of review by the FERC for changing power contracts, and could have the effect of requiring the FERC in advance to review most, if not all, power contracts. In June 2008, the U.S. Supreme Court reversed one of the decisions of the U.S. Court of Appeals for the Ninth Circuit, thereby upholding the higher standard of review for modifying contracts. The FERC has not yet taken action in response to these court decisions. At this time, PPL, PPL Energy Supply, LKE, LG&E and KU cannot predict the impact of these court decisions on the FERC's future market-based rate authority program or on their businesses.

 

Energy Policy Act of 2005 - Reliability Standards (PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

The NERC is responsible for establishing and enforcing mandatory reliability standards (Reliability Standards) regarding the bulk power system. The FERC oversees this process and independently enforces the Reliability Standards.

 

The Reliability Standards have the force and effect of law and apply to certain users of the bulk power electricity system, including electric utility companies, generators and marketers. The FERC has indicated it intends to vigorously enforce the Reliability Standards using, among other means, civil penalty authority. Under the Federal Power Act, the FERC may assess civil penalties of up to $1 million per day, per violation, for certain violations. The first group of Reliability Standards approved by the FERC became effective in June 2007.

 

LG&E, KU, PPL Electric and certain subsidiaries of PPL Energy Supply continue to self-report potential violations of certain applicable reliability requirements and submit accompanying mitigation plans. The resolution of a number of these potential violation reports is pending. Any regional reliability entity determination concerning the resolution of violations of the Reliability Standards remains subject to the approval of the NERC and the FERC. PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU cannot predict the outcome of these matters, and cannot estimate a range of reasonably possible losses, if any, other than the amounts currently recorded.

 

In the course of implementing its program to ensure compliance with the Reliability Standards by those PPL affiliates subject to the standards, certain other instances of potential non-compliance may be identified from time to time.

Environmental Matters - Domestic

 

(PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

Due to the environmental issues discussed below or other environmental matters, PPL subsidiaries may be required to modify, curtail, replace or cease operating certain facilities or operations to comply with statutes, regulations and other requirements of regulatory bodies or courts.

 

(PPL, PPL Energy Supply, LKE, LG&E and KU)

 

Air

 

The Clean Air Act addresses, among other things, emissions causing acid deposition, installation of best available control technologies for new or substantially modified sources, attainment of national ambient air quality standards, toxic air emissions and visibility standards in the U.S. Amendments to the Clean Air Act requiring additional emission reductions had been proposed but are unlikely to be introduced or passed in this Congress. The Clean Air Act allows states to develop more stringent regulations and in some instances, as discussed below, Kentucky, Pennsylvania and Montana have done so.

 

To comply with air related requirements and other environmental requirements as described below, PPL's forecast for capital expenditures reflects a best estimate projection of expenditures that may be required within the next five years. Such projections are a combined $3.1 billion for LG&E and KU (which includes $600 million currently approved in its ECR plans during the 2011 through 2013 time period to achieve emissions reductions and manage coal combustions residuals and $2.5 billion recently requested through the 2011 ECR Plan for additional expenditures to comply with new clean air rules and manage coal combustion residuals) and $400 million for PPL Energy Supply. Actual costs may be significantly lower or higher depending on the final requirements. Certain environmental compliance costs incurred by LG&E and KU in serving KPSC jurisdictional customers are subject to recovery through the ECR. See Note 6 for additional information on the ECR plan.

 

Cross State Air Pollution Rule (CSAPR) formerly Clean Air Transport Rule

 

In July 2011, the EPA signed the CSAPR which finalizes and renames the Clean Air Transport Rule (Transport Rule) proposed in August 2010. The CSAPR replaces the EPA's previous Clean Air Interstate Rule (called CAIR) which was struck down by the U.S. Court of Appeals for the District of Columbia Circuit (the Court) in July 2008. CAIR subsequently was effectively reinstated by the Court in December 2008, pending finalization of the Transport Rule. Like CAIR and the proposed Transport Rule, the CSAPR only applies to PPL's generation facilities located in Kentucky and Pennsylvania.

 

The CSAPR is meant to facilitate attainment of ambient air quality standards for ozone and fine particulates by requiring reductions in sulfur dioxide and nitrogen oxides. The CSAPR establishes a new sulfur dioxide emission allowance cap and trade program that is completely independent of and more stringent than the current Acid Rain Program. The CSAPR also establishes new nitrogen oxide emission allowance cap and trade programs to replace the current programs that are also more restrictive than the existing programs. All trading is more restrictive than previously under CAIR. The CSAPR will be implemented in two phases. The first phase of the sulfur dioxide and nitrogen oxide emissions caps becomes effective in 2012. The second phase, lowering both of these caps, becomes effective in 2014.

 

With respect to PPL's competitive generation in Pennsylvania, greater reductions in sulfur dioxide emissions will be required beginning in 2012 under CSAPR than were required under CAIR starting in 2015. For the initial phase of the rule beginning in 2012, PPL Energy Supply's sulfur dioxide allowance allocations are expected to meet the forecasted emissions based on present operations of existing scrubbers and coal supply. For the second phase beginning in 2014, the further reduction in allocations will most likely be met with increased operations of the existing scrubbers. With respect to nitrogen oxide, CSAPR provides a slightly higher amount of allowances for PPL Energy Supply's Pennsylvania plants, but still less than PPL Energy Supply's current forecasted emissions. With uncertainty surrounding the trading program, other compliance options are being analyzed for the Pennsylvania fleet, such as the installation of new technology or modifications of plant operations.

 

With respect to LG&E and KU, greater reductions in sulfur dioxide emissions will also be required under the CSAPR beginning in 2012 than were required under CAIR starting in 2015. For the initial phase of the rule beginning in 2012, sulfur dioxide allowance allocations are expected to meet the forecasted emissions based on present operations of existing scrubbers and coal supply. However, by the second phase beginning in 2014, LG&E and KU will likely have to take additional measures with respect to the operation and dispatch of their generation fleet, including upgrades or installation of new scrubbers for certain generating units or retirement of certain units. With respect to nitrogen oxide, the CSAPR allocates a slightly lower amount of allowances compared to those allocated under CAIR. With uncertainty surrounding the trading program, other compliance options are being analyzed for the Kentucky fleet, such as the installation of new technology, the retirement of certain units and modifications of plant operations. LG&E and KU are seeking recovery of their expected costs to comply with the CSAPR and certain other EPA requirements through the ECR plan filed with the KPSC in June 2011. See Note 6 for additional information.

 

In addition to the reductions in sulfur dioxide and nitrogen oxide emissions required under the CSAPR for the Pennsylvania and Kentucky plants, PPL's plants, including those in Montana, may face further reductions in sulfur dioxide and nitrogen oxide emissions as a result of more stringent national ambient air quality standards for ozone, nitrogen oxide, sulfur dioxide and/or fine particulates. The EPA has recently finalized a new one-hour standard for sulfur dioxide, and states are required to identify areas that meet those standards and areas that are in non-attainment. For non-attainment areas, states are required to develop plans by 2014 to achieve attainment by 2017. For areas in attainment or unclassifiable, states are required to develop maintenance plans by mid-2013 that demonstrate continued attainment. PPL, PPL Energy Supply, LKE, LG&E and KU anticipate that some of the measures required for compliance with CSAPR such as upgraded or new scrubbers at some of their plants or retirements of certain units may also be necessary to achieve compliance with new sulfur dioxide standards. If additional reductions were to be required, the economic impact to each could be significant.

 

Mercury and other Hazardous Air Pollutants

 

Citing its authority under the Clean Air Act, in 2005, the EPA issued the Clean Air Mercury Rule (CAMR) affecting coal-fired power plants. Since the CAMR was overturned in a 2008 U.S. Circuit Court decision, the EPA is now proceeding to develop standards imposing MACT for mercury emissions and other hazardous air pollutants from electric generating units. Under a recently approved settlement, the EPA is required to issue final MACT standards by November 2011. In order to develop these standards, the EPA has collected information from coal- and oil-fired electric utility steam generating units. In May 2011, the EPA published a proposed MACT regulation providing for stringent reductions of mercury and other hazardous air pollutants. The proposed rule also provides for a three-year compliance deadline, with the potential for a one-year extension as provided under the statute. Based on their assessment of the need to install pollution control equipment to meet this rule, LG&E and KU have filed requests with the KPSC for environmental cost recovery to facilitate moving forward with plans to install environmental controls including sorbent injection and fabric-filter baghouses to remove certain hazardous air pollutants. The cost for these controls is reflected in the $2.5 billion cost noted under "Air" above. LG&E and KU are also evaluating the potential for shutdown of certain units for which retrofits would not be cost-effective. The potential economic impact on PPL Energy Supply plants, including plant closures or other actions, cannot be estimated at this time, however, such impact could be significant. PPL Energy Supply, LG&E and KU are continuing to conduct in-depth reviews of the proposed rule.

 

Regional Haze and Visibility

 

The Clean Air Visibility Rule was issued by the EPA in June 2005 to address regional haze or regionally-impaired visibility caused by multiple sources over a wide area. The rule requires Best Available Retrofit Technology (BART) for certain electric generating units. Under the BART rule, PPL submitted to the PADEP its analyses of the visibility impacts of particulate matter emissions from Martins Creek Units 3 and 4, Brunner Island Units 2 and 3 and Montour Units 1 and 2. No analysis was submitted for sulfur dioxide or nitrogen oxides, because the EPA determined that meeting the requirements for the CAIR also satisfies the BART requirements for those pollutants. Although the EPA has not yet expressly stated that a similar approach will be taken under the CSAPR, the EPA has not requested any further studies. PPL's analyses have shown that, because PPL had already upgraded its particulate emissions controls at Montour Units 1 and 2 and Brunner Island Units 2 and 3, further controls are not justified as there would be little corresponding visibility improvement. PPL has not received comments from the PADEP on these submissions.

 

Also under the BART rule, PPL submitted to the EPA its analyses of the visibility impacts of sulfur dioxide, nitrogen oxides and particulate matter emissions for Colstrip Units 1 and 2 and Corette. PPL's analyses concluded that further reductions are not warranted. The EPA responded to PPL's reports for Colstrip and Corette and requested further information and analysis. PPL completed further analysis and submitted addendums to its initial reports for Colstrip and Corette. In February 2009, PPL received an information request for additional data related to the Colstrip generating plant non-BART-affected emission sources. PPL responded to this request in March 2009.

 

In November 2010, PPL Montana received a request from the EPA Region 8, under EPA's Reasonable Further Progress goals of the Regional Haze Rules, to provide further analysis with respect to Colstrip Units 3 and 4. Colstrip's Units 3 and 4 are not BART eligible units. PPL completed a high-level analysis of various control options to reduce emissions of sulfur dioxide and particulate matter, and submitted that analysis to the EPA in January 2011. The analysis shows that any incremental reductions would not be cost effective and that further analysis is not warranted. PPL also concluded that further analysis for nitrogen oxides was not justifiable as these units installed controls under a Consent Decree in which the EPA had previously agreed that, when implemented, would satisfy the requirements for installing BART for nitrogen oxides. The EPA has indicated that it does not agree with all of PPL's conclusions and has requested additional information to which PPL is responding. Additionally, the EPA recently informally indicated to PPL Montana that substantially more reductions in both nitrogen oxide and sulfur dioxide emissions may be required.

 

PPL and PPL Energy Supply cannot predict whether any additional reductions in emissions will be required in Pennsylvania or Montana. If additional reductions are required, the economic impact could be significant depending on what is required.

 

LG&E and KU also submitted analyses of the visibility impacts of their Kentucky BART-eligible sources to the Kentucky Division for Air Quality (KDAQ). Only LG&E's Mill Creek plant was determined to have a significant regional haze impact. The KDAQ has submitted a regional haze state implementation plan (SIP) to the EPA which requires the Mill Creek plant to reduce its sulfuric acid mist emissions from Units 3 and 4. After approval of the Kentucky SIP by the EPA and revision of the Mill Creek plant's Title V air permit, LG&E intends to install sorbent injection controls at the plant to reduce sulfuric acid mist emissions. In the event that the EPA determines that compliance with CSAPR would be insufficient to meet BART requirements, it would be necessary for LG&E and KU to reassess their planned compliance measures.

 

New Source Review (NSR)

 

The EPA has resumed its NSR enforcement efforts targeting coal-fired power plants. The EPA has asserted that modification of these plants has increased their emissions and, consequently, that they are subject to stringent NSR requirements under the Clean Air Act. In April 2009, PPL received EPA information requests for its Montour and Brunner Island plants. The requests are similar to those that PPL received several years ago for its Colstrip, Corette and Martins Creek plants. PPL and the EPA have exchanged certain information regarding this matter. In January 2009, PPL and other companies that own or operate the Keystone plant in Pennsylvania received a notice of violation from the EPA alleging that certain projects were undertaken without proper NSR compliance. PPL and PPL Energy Supply cannot predict the outcome of these matters, and cannot estimate a range of reasonably possible losses, if any.

 

In addition, in August 2007, LG&E and KU received information requests for their Mill Creek, Trimble County, and Ghent plants, but have received no further communications from the EPA since providing their responses. PPL, LKE, LG&E and KU cannot predict the outcome of these matters, and cannot estimate a range of reasonably possible losses, if any.

 

In March 2009, KU received a notice of violation alleging that KU violated certain provisions of the Clean Air Act's rules governing NSR and prevention of significant deterioration by installing flue gas desulfurization and SCR controls at its Ghent generating station without assessing potential increased sulfuric acid mist emissions. KU contends that the work in question, as pollution control projects, was exempt from the requirements cited by the EPA. In December 2009, the EPA issued an information request seeking additional information on this matter. KU has exchanged settlement proposals and other information with the EPA regarding imposition of additional permit limits and emission controls and anticipates continued settlement negotiations. In addition, any settlement or future litigation could potentially encompass a September 2007 notice of violation alleging opacity violations at the plant. Depending on the provisions of a final settlement or the results of litigation, if any, resolution of this matter could involve significant increased operating and capital expenditures. PPL, LKE and KU are currently unable to predict the final outcome of this matter, and cannot estimate a range of reasonably possible losses, if any.

 

If PPL subsidiaries are found to have violated NSR regulations, PPL would, among other things, be required to meet permit limits reflecting Best Available Control Technology (BACT) for the emissions of any pollutant found to have significantly increased due to a major plant modification. The costs to meet such limits, including installation of technology at certain units, could be significant.

 

States and environmental groups also have initiated enforcement actions and litigation alleging violations of the NSR regulations by coal-fired plants, and PPL is unable to predict whether such actions will be brought against any of PPL's plants.

 

Pursuant to the 2007 U.S. Supreme Court decision on global climate change, as discussed below, the EPA issued regulations governing carbon dioxide emissions from new or modified stationary sources under its NSR regulations. The regulations became effective beginning January 2011. The NSR regulations require major new or modified sources of regulated pollutants to receive pre-construction and operating permits with limits that prevent the significant deterioration of air quality in areas that are in attainment of the ambient air quality standards for certain pollutants. In May 2010, the EPA published a final rule establishing thresholds for regulating GHG emissions from major new or modified sources. Combined carbon dioxide emissions or carbon dioxide equivalent emissions of 100,000 tons or more per year will classify a source as major for permitting applicability purposes. The threshold for a major modification of a major source is an increase of carbon dioxide or carbon dioxide equivalent emissions of 75,000 tons per year, although a significant increase in non carbon dioxide regulated pollutants is also required for modifications undertaken prior to July 2011. If a modification results in emissions increases exceeding the threshold, the plant will need to conduct an analysis of BACT for GHG and meet limits based on BACT. To date, the EPA has not provided final guidance on what constitutes BACT for GHG emissions, but has indicated in draft guidance that it may consider efficiency projects and other options as possible best available control technology for carbon dioxide emissions from power plants. In addition, in December 2010, the EPA announced that it intends to promulgate New Source Performance Standards addressing GHG emissions from new and existing power plants, with a proposed rule currently anticipated to be published in September 2011 and a final rule issued in May 2012. The implications of these developments, including the outcome of any litigation challenging these regulations, are uncertain.

 

Trimble County Unit 2 Air Permit (PPL, LKE, LG&E and KU)

 

The Sierra Club and other environmental groups petitioned the Kentucky Environmental and Public Protection Cabinet to overturn the air permit issued for the TC2 baseload generating unit, but the agency upheld the permit in an Order issued in September 2007. In response to subsequent petitions by environmental groups, the EPA ordered certain non-material changes to the permit which were incorporated into a final revised permit issued by the KDAQ in January 2010. In March 2010, the environmental groups petitioned the EPA to object to the revised state permit. Until the EPA issues a final ruling on the pending petition and all available appeals are exhausted, PPL, LKE, LG&E and KU cannot currently predict the outcome of this matter or the potential impact on the capital costs of this project.

 

(PPL, PPL Energy Supply, LKE, LG&E and KU)

 

Global Climate Change

 

There is concern nationally and internationally about global climate change and the possible contribution of GHG emissions including, most significantly, carbon dioxide, from the combustion of fossil fuels. This has resulted in increased demands for carbon dioxide emission reductions from investors, environmental organizations, government agencies and the international community. These demands and concerns have led to federal legislative proposals, actions at regional, state and local levels, litigation relating to GHG emissions and the EPA regulations on GHGs.

 

Greenhouse Gas Legislation

 

While climate change legislation was considered during the 111th Congress, the outcome of the 2010 elections has halted the debate on such legislation in the current 112th Congress. The timing and elements of any future legislation addressing GHG emission reductions are uncertain at this time. In the current Congress, legislation barring EPA from regulating GHG emissions under the existing authority of the Clean Air Act has been passed by the U.S. House of Representatives. Various bills providing for barring or delaying the EPA from regulating GHG emissions have been introduced in the U.S. Senate, but the prospects for passage of such legislation remain uncertain. At the state level, the 2010 elections in Pennsylvania have also reduced the likelihood of GHG legislation in the near term, and there are currently no prospects for such legislation in Kentucky or Montana.

 

Greenhouse Gas Regulations and Tort Litigation

 

As a result of the April 2007 U.S. Supreme Court decision that the EPA has the authority to regulate GHG emissions from new motor vehicles under the Clean Air Act, in April 2010, the EPA and the U.S. Department of Transportation issued new light-duty vehicle emissions standards that will apply beginning with 2012 model year vehicles. The EPA has also clarified that this standard triggers regulation of GHG emissions from stationary sources under the NSR and Title V operating permit provisions of the Clean Air Act starting in 2011. This means that any new sources or major modifications to existing sources causing a net significant emissions increase requires BACT permit limits for GHGs. The EPA recently proposed guidance for conducting a BACT analysis for projects that trigger such a review. In addition, New Source Performance Standards for new and existing power plants are expected to be proposed in September 2011 and finalized in May 2012.

 

At the regional level, ten northeastern states signed a Memorandum of Understanding (MOU) agreeing to establish a GHG emission cap-and-trade program, called the Regional Greenhouse Gas Initiative (RGGI). The program commenced in January 2009 and calls for stabilizing carbon dioxide emissions, at base levels established in 2005, from electric power plants with capacity greater than 25 MW. The MOU also provides for a 10% reduction in carbon dioxide emissions from base levels by 2019.

 

Pennsylvania has not stated an intention to join RGGI, but has enacted the Pennsylvania Climate Change Act of 2008 (PCCA). The PCCA established a Climate Change Advisory Committee to advise the PADEP on the development of a Climate Change Action Plan. In December 2009, the Advisory Committee finalized its Climate Change Action Report which identifies specific actions that could result in reducing GHG emissions by 30% by 2020. Some of the proposed actions, such as a mandatory 5% efficiency improvement at power plants, could be technically unachievable. To date, there have been no regulatory or legislative actions taken to implement the recommendations of the report. In addition, legislation has been introduced and amendments filed to several bills that would, if enacted, significantly increase renewable and solar supply requirements. It is unlikely that this legislation will achieve passage in the 2011 legislative session.

 

Eleven Western states, including Montana and certain Canadian provinces, are members of the Western Climate Initiative (WCI). The WCI has established a goal of reducing carbon dioxide emissions 15% below 2005 levels by 2020 and is currently developing GHG emission allocations, offsets, and reporting recommendations.

 

In November 2008, the Governor of Kentucky issued a comprehensive energy plan including non-binding targets aimed at promoting improved energy efficiency, development of alternative energy, development of carbon capture and sequestration projects, and other actions to reduce GHG emissions. In December 2009, the Kentucky Climate Action Plan Council was established to develop an action plan addressing potential GHG reductions and related measures. A final plan is expected in 2011. The impact of any such plan is not now determinable, but the costs to comply with the plan could be significant.

 

A number of lawsuits have been filed asserting common law claims including nuisance, trespass and negligence against various companies with GHG emitting facilities, and the law remains unsettled on these claims. In September 2009, the U.S. Court of Appeals for the Second Circuit in the case of AEP v. Connecticut reversed a federal district court's decision and ruled that several states and public interest groups, as well as the City of New York, could sue five electric utility companies under federal common law for allegedly causing a public nuisance as a result of their emissions of GHGs. In June 2011, the U.S. Supreme Court overturned the lower court and held that such federal common law claims were displaced by the Clean Air Act and regulatory actions of the EPA. In Comer v. Murphy Oil, the U.S. Court of Appeals for the Fifth Circuit recently declined to overturn a district court ruling that plaintiffs did not have standing to pursue state common law claims against companies that emit GHGs. The complaint in the Comer case named the previous indirect parent of LKE as a defendant based upon emissions from the Kentucky plants. In January 2011, the Supreme Court denied a pending petition to reverse the Court of Appeals' ruling. In May 2011, the plaintiffs in the Comer case filed a substantially similar complaint in federal district court in Mississippi against 87 companies, including KU and three other indirect subsidiaries of LKE, under a Mississippi statute that allows the re-filing of an action in certain circumstances. Additional litigation in federal and state courts over these issues is continuing. PPL, LKE and KU cannot predict the outcome of this litigation or estimate a range of reasonably possible losses, if any.

 

PPL continues to evaluate options for reducing, avoiding, off-setting or sequestering its carbon dioxide emissions. In 2010, PPL's power plants, including PPL's share of jointly owned assets, emitted approximately 37 million tons of carbon dioxide (including 6 million tons of emissions from the LKE plants after their acquisition on November 1, 2010) compared to 29 million tons in 2009 without LG&E and KU emissions. LG&E's and KU's generating fleets, including their share of jointly owned assets, emitted approximately 19 million tons and approximately 18 million tons of carbon dioxide in 2010, compared to approximately 17 million tons and approximately 16 million tons in 2009. All tons are U.S. short tons (2,000 lbs/ton).

 

Renewable Energy Legislation (PPL and PPL Energy Supply)

 

There has been interest in renewable energy legislation at both the state and federal levels. At the federal level, House and Senate bills proposed in the 111th Congress would have imposed mandatory renewable energy supply and energy efficiency requirements in the 15% to 20% range by approximately 2020. Earlier in the year, there were discussions regarding a Clean Energy Standard (CES) that addressed not only renewables but also encouraged clean energy requirements (as yet to be defined). At this time, neither the renewable energy debate nor the CES discussion is expected to gain momentum at the federal or state levels (beyond what is otherwise already required in Pennsylvania and Montana) in the near term.

 

PPL believes there are financial, regulatory and logistical uncertainties related to GHG reductions and the implementation of renewable energy mandates. These will need to be resolved before the impact of such requirements on PPL can be meaningfully estimated. Such uncertainties, among others, include the need to provide back-up supply to augment intermittent renewable generation, potential generation oversupply that could result from such renewable generation and back-up, impacts to PJM's capacity market and the need for substantial changes to transmission and distribution systems to accommodate renewable energy. These uncertainties are not directly addressed by proposed legislation. PPL and PPL Energy Supply cannot predict at this time the effect on their future competitive position, results of operation, cash flows and financial position, of any GHG emissions, renewable energy mandate or other global climate change requirements that may be adopted, although the costs to implement and comply with any such requirements could be significant.

 

Water/Waste

 

Coal Combustion Residuals (CCRs) (PPL, PPL Energy Supply, LKE, LG&E and KU)

 

In June 2010, the EPA proposed two approaches to regulating the disposal and management of CCRs under the Resource Conservation and Recovery Act (RCRA). CCRs include fly ash, bottom ash and scrubber wastes. The first approach would regulate CCRs as a hazardous waste under Subtitle C of the RCRA. This approach would have very significant impacts on any coal-fired plant, and would require plants to retrofit their operations to comply with full hazardous waste requirements from the generation of CCRs and associated waste waters through transportation and disposal. This would also have a negative impact on the beneficial use of CCRs and could eliminate existing markets for CCRs. The second approach would regulate CCRs as a solid waste under Subtitle D of the RCRA. This approach would mainly affect disposal and most significantly affect any wet disposal operations. Under this approach, many of the current markets for beneficial uses would not be affected. Currently, PPL expects that several of its plants in Kentucky and Montana could be significantly impacted by the requirements of Subtitle D of the RCRA, as these plants are using surface impoundments for management and disposal of CCRs.

 

The EPA has issued information requests on CCR management practices at numerous plants throughout the power industry as it considers whether or not to regulate CCRs as hazardous waste. PPL has provided information on CCR management practices at most of its plants in response to the EPA's requests. In addition, the EPA has conducted follow-up inspections to evaluate the structural stability of CCR management facilities at several PPL plants and PPL has implemented certain actions in response to recommendations from these inspections.

 

The EPA is continuing to evaluate the unprecedented number of comments it received on its June 2010 proposed regulations and in July 2011 issued a notice of data availability requesting additional comments on certain information collected as part of the regulatory development process. In addition, the House Energy and Commerce Committee approved a bill to modify Subtitle D of the RCRA to provide for the proper management and disposal of CCRs and that would preclude the EPA from regulating CCRs under Subtitle C of the RCRA.

 

In June 2009, the EPA's Office of Enforcement and Compliance Assurance issued a much broader information request to Colstrip and 18 other non-affiliated plants, seeking information under the RCRA, the Clean Water Act and the Emergency Planning and Community Right-to-Know Act. PPL responded to the EPA's broader information request. Although the EPA's enforcement office issued the request, the EPA has not necessarily concluded that the plants are in violation of any EPA requirements. The EPA conducted a multi-media inspection at Colstrip in August 2009 and issued a report in December 2010 stating that the EPA did not identify any violations of the applicable compliance standards for the Colstrip facility.

 

PPL, PPL Energy Supply, LKE, LG&E and KU cannot predict at this time the final requirements of the EPA's CCR regulations or potential changes to the RCRA and what impact they would have on their facilities, but the economic impact could be significant.

 

Martins Creek Fly Ash Release (PPL and PPL Energy Supply)

 

In 2005, there was a release of approximately 100 million gallons of water containing fly ash from a disposal basin at the Martins Creek plant used in connection with the operation of the plant's two 150 MW coal-fired generating units. This resulted in ash being deposited onto adjacent roadways and fields, and into a nearby creek and the Delaware River. PPL determined that the release was caused by a failure in the disposal basin's discharge structure. PPL conducted extensive clean-up and completed studies, in conjunction with a group of natural resource trustees and the Delaware River Basin Commission, evaluating the effects of the release on the river's sediment, water quality and ecosystem.

 

The PADEP filed a complaint in Pennsylvania Commonwealth Court against PPL Martins Creek and PPL Generation, alleging violations of various state laws and regulations and seeking penalties and injunctive relief. PPL and the PADEP have settled this matter. The settlement also required PPL to submit a report on the completed studies of possible natural resource damages. PPL subsequently submitted the assessment report to the Pennsylvania and New Jersey regulatory agencies and has continued discussing potential natural resource damages and mitigation options with the agencies.

 

Through June 30, 2011, PPL Energy Supply has spent $28 million for remediation and related costs and an insignificant remediation liability remains on the balance sheet. PPL and PPL Energy Supply cannot be certain of the outcome of the natural resource damage assessment or the associated costs, the outcome of any lawsuit that may be brought by citizens or businesses or the exact nature of any other regulatory or other legal actions that may be initiated against PPL, PPL Energy Supply or their subsidiaries as a result of the disposal basin release. However, PPL and PPL Energy Supply currently do not expect such outcomes to result in material losses above the amounts currently recorded.

 

Basin Seepage – Pennsylvania and Kentucky (PPL, PPL Energy Supply, LKE, LG&E and KU)

 

Seepages have been detected at active and retired wastewater basins at various PPL plants. PPL has completed or is completing assessments of seepages at various facilities and is working with agencies to implement abatement measures for those seepages, where required. A range of reasonably possible losses cannot currently be estimated.

 

Basin Seepage - Montana (PPL and PPL Energy Supply)

 

In 2007, six plaintiffs filed a lawsuit in the Montana Sixteenth Judicial District Court against the Colstrip plant owners asserting property damage claims from seepage from wastewater ponds at Colstrip. A tentative settlement agreement was reached in July 2010. The settlement is not yet final, and may not be honored by the plaintiffs, but PPL Montana's share is not expected to be significant.

 

Conemaugh River Discharges (PPL and PPL Energy Supply)

 

In April 2007, PennEnvironment and the Sierra Club brought a Clean Water Act citizen suit in the U.S. District Court for the Western District of Pennsylvania (the Western District Court) against GenOn Northeast Management Company (then known as Reliant Energy Northeast Management Company) (GenOn), as operator of Conemaugh Generating Station (CGS), seeking civil penalties and injunctive relief for alleged violations of CGS's NPDES water discharge permit. A PPL Energy Supply subsidiary holds a 16.25% undivided, tenant-in-common ownership interest in CGS.

 

Throughout the relevant time period, the operators of CGS have worked closely with the PADEP to ensure that the facility is operated in a manner that does not cause any adverse environmental impacts to the Conemaugh River, a waterway already significantly impacted by discharges from abandoned coal mines and other historical industrial activity with respect to which neither PPL nor CGS had any involvement.  Pursuant to a Consent Order and Agreement between the PADEP and GenOn (the CGS COA), a variety of studies have been conducted, a water treatment facility for cooling tower blowdown has been designed and built, and a second treatment facility for flue gas desulfurization effluent has been designed (and is awaiting final PADEP approval for construction), all in order to comply with the stringent limits set out in CGS's NPDES permit.

 

In the lawsuit, GenOn has argued that the CGS COA should preclude the plaintiffs from maintaining their lawsuit, but the Western District Court has disagreed and there is no binding precedent on the matter. The Western District Court initially dismissed plaintiffs' lawsuit in December 2009 for lack of standing, but in September 2010 granted plaintiffs' motion for reconsideration and reinstated the lawsuit. In both cases, the Western District Court disagreed that the CGS COA precluded the lawsuit.

 

In March 2011, the Western District Court entered a partial summary judgment in the plaintiffs' favor, declaring that discharges from CGS violated the NPDES permit. The case was originally scheduled for a non-jury trial starting in June 2011, at which time the Western District Court was expected to determine what, if any, civil penalties and injunctive relief might be appropriate. The non-jury trial was subsequently postponed and the parties are engaged in settlement discussions. In the event of an adverse verdict at trial, an appeal is likely. If the plaintiffs are ultimately successful, PPL Energy Supply could incur its share of any civil penalties and costs to implement additional discharge reductions. PPL and PPL Energy Supply cannot predict the outcome of this matter but do not expect any potential losses to be significant.

 

Other Issues (PPL, PPL Energy Supply, LKE, LG&E and KU)

 

In 2006, the EPA significantly decreased to 10 parts per billion (ppb) the drinking water standards related to arsenic. In Pennsylvania, Montana and Kentucky, this arsenic standard has been incorporated into the states' water quality standards and could result in more stringent limits in NPDES permits for its Pennsylvania, Montana and Kentucky plants. Subsequently, the EPA developed a draft risk assessment for arsenic that increases the cancer risk exposure by more than 20 times, which would lower the current standard from 10 ppb to 0.1 ppb. If the lower standard becomes effective, costly treatment would be required to attempt to meet the standard and, at this time, there is no assurance that it could be achieved. PPL, PPL Energy Supply, LKE, LG&E and KU cannot predict the outcome of the draft risk assessment and what impact, if any, they would have on their facilities, but the costs could be significant.

 

The EPA is reassessing its polychlorinated biphenyls (PCB) regulations under the Toxics Substance Control Act, which currently allow certain PCB articles to remain in use. In April 2010, the EPA issued an Advanced Notice of Proposed Rulemaking for changes to these regulations. This rulemaking could lead to a phase-out of all PCB-containing equipment. PPL, PPL Energy Supply, LKE, LG&E and KU cannot predict at this time the outcome of these proposed EPA regulations and what impact, if any, they would have on their facilities, but the costs could be significant.

 

The EPA finalized requirements in 2004 for new or modified cooling water intake structures. These requirements affect where generating facilities are built, establish intake design standards and could lead to requirements for cooling towers at new and modified power plants. Another rule, finalized in 2004, that addressed existing structures was withdrawn following a 2007 decision by the U.S. Court of Appeals for the Second Circuit. In 2009, however, the U.S. Supreme Court ruled that the EPA has discretion to use cost-benefit analysis in determining the best technology available for minimizing adverse environmental impact to aquatic organisms. The EPA published the proposed rule in the Federal Register in April 2011. The comment period ends in August 2011. The final rule is to be issued by July 2012. The industry and PPL are reviewing the proposed rule and will be submitting comments. The proposed rule contains two requirements to reduce impact to aquatic organisms. The first requires all existing facilities to meet standards for the reduction of mortality of aquatic organisms that become trapped against water intake screens regardless of the levels of mortality actually occurring or the cost of achieving the requirements. A form of cost-benefit analysis is allowed for the second requirement when determining mortality of aquatic organisms that are pulled through the plant's cooling water system. This process involves a site-specific evaluation based on nine factors including impacts to energy delivery reliability and remaining useful life of the plant. Since the rule is written to allow for certain site-specific determinations of the best technology available, state implementation of the rule could impose requirements that could result in significant costs to PPL plants ranging from installation of fine mesh screens on cooling water intakes to construction of cooling towers. PPL, PPL Energy Supply, LKE, LG&E and KU will be unable to determine the exact impact until a final rule is issued and the required studies have been completed.

 

In October 2009, the EPA released its Final Detailed Study of the Steam Electric Power Generating effluent limitations guidelines and standards. Final regulations are expected to be effective in 2013. PPL expects the revised guidelines and standards to be more stringent than the current standards, which could result in more stringent discharge permit limits.

 

PPL has signed a Consent Order and Agreement (the Brunner COA) with the PADEP under which it agreed, under certain conditions, to take further actions to minimize the possibility of fish kills at its Brunner Island plant. Fish are attracted to warm water in the power plant discharge channel, especially during cold weather. Debris at intake pumps can result in a unit trip or reduction in load, causing a sudden change in water temperature. PPL has committed to construct a barrier to prevent debris from entering the river water intake area, pending receipt of regulatory permits, at a cost of approximately $4 million.

 

PPL has also investigated alternatives to exclude fish from the discharge channel and submitted three alternatives to the PADEP. According to the Brunner COA, once the cooling towers at Brunner Island became operational, PPL must implement one of these fish exclusion alternatives if a fish kill occurs in the discharge channel due to thermal impacts from the plant. Following start-up of the cooling towers in April 2010, several hundred dead fish were found in the cooling tower intake basket although there were no sudden changes in water temperature. In the third quarter of 2010, PPL discussed this matter with the PADEP and both parties agreed that this condition was not one anticipated by the Brunner COA, thereby concluding it did not trigger a need to implement a fish exclusion project. At this time, no fish exclusion project is planned.

 

In May 2010, the Kentucky Waterways Alliance and other environmental groups filed a petition with the Kentucky Energy and Environment Cabinet challenging the Kentucky Pollutant Discharge Elimination System permit issued in April 2010, which covers water discharges from the Trimble County station. In November 2010, the Cabinet issued a final order upholding the permit. In December 2010, the environmental groups appealed the order to Trimble Circuit Court. PPL, LKE and LG&E are unable to predict the outcome of this matter or estimate a range of reasonably possible losses, if any.

 

(PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

Superfund and Other Remediation

 

PPL is a potentially responsible party at several sites listed by the EPA under the federal Superfund program, including the Columbia Gas Plant site, the Metal Bank site and the Ward Transformer site. Clean-up actions have been or are being undertaken at all of these sites, the costs of which have not been significant to PPL. However, should the EPA require different or additional measures in the future, or should PPL's share of costs at multi-party sites increase significantly more than currently expected, the costs to PPL could be significant.

 

PPL is remediating or has completed the remediation of several sites that were not addressed under a regulatory program such as Superfund, but for which PPL may be liable for remediation. These include a number of former coal gas manufacturing facilities in Pennsylvania and Kentucky previously owned or operated or currently owned by predecessors or affiliates of PPL. There are additional sites, formerly owned or operated by PPL predecessors or affiliates, for which PPL lacks information on current site conditions and is therefore unable to predict what, if any, potential liability it may have.

 

In June 2011, Lepore-Moyers Partnership (LMP) filed a complaint in federal district court against PPL Electric, UGI Corporation and a neighboring property owner relating to contamination allegedly emanating from the former Mount Joy Manufactured Gas Plant (MGP) site located in Lancaster County, Pennsylvania. LMP owns property adjacent to the Mount Joy MGP site and claims that environmental testing done on its property indicates the presence of volatile organic compounds in the soil and/or groundwater. LMP claims that defendants are responsible for, among other things, the reimbursement of costs, future response costs, investigation and remediation of the contamination, and damages caused by the contamination. PPL and PPL Electric cannot estimate a range of reasonably possible losses, if any, or predict the outcome of this matter.

 

Depending on the outcome of investigations at sites where investigations have not begun or been completed or developments at sites for which PPL currently lacks information, the costs of remediation and other liabilities could be substantial. PPL and its subsidiaries also could incur other non-remediation costs at sites included in current consent orders or other contaminated sites which could be significant. PPL is unable to estimate a range of reasonably possible losses, if any, related to these matters.

 

The EPA is evaluating the risks associated with polycyclic aromatic hydrocarbons and naphthalene, chemical by-products of coal gas manufacturing. As a result of the EPA's evaluation, individual states may establish stricter standards for water quality and soil cleanup. This could require several PPL subsidiaries to take more extensive assessment and remedial actions at former coal gas manufacturing facilities PPL cannot estimate a range of reasonably possible losses, if any, related to these matters.

 

Under the Pennsylvania Clean Streams Law, subsidiaries of PPL Generation are obligated to remediate acid mine drainage at former mine sites and may be required to take additional steps to prevent potential acid mine drainage at previously capped refuse piles. One PPL Generation subsidiary is pumping mine water at two mine sites and treating water at one of these sites. Another PPL Generation subsidiary has installed a passive wetlands treatment system at a third site. At June 30, 2011, PPL Energy Supply had accrued a discounted liability of $26 million to cover the costs of pumping and treating groundwater at the two mine sites for 50 years and for operating and maintaining passive wetlands treatment at the third site. PPL Energy Supply discounted this liability based on risk-free rates at the time of the mine closures. The weighted-average rate used was 8.16%. Expected undiscounted payments are estimated at $2 million for 2011, $1 million for each of the years from 2012 through 2014, $2 million for 2015, and $137 million for work after 2015.

 

From time to time, PPL undertakes remedial action in response to spills or other releases at various on-site and off-site locations, negotiates with the EPA and state and local agencies regarding actions necessary for compliance with applicable requirements, negotiates with property owners and other third parties alleging impacts from PPL's operations, and undertakes similar actions necessary to resolve environmental matters which arise in the course of normal operations. Based on analyses to date, resolution of these general environmental matters is not expected to have a material adverse impact on PPL's operations.

 

Future cleanup or remediation work at sites currently under review, or at sites not currently identified, may result in material additional costs for PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU.

 

Electric and Magnetic Fields

 

Concerns have been expressed by some members of the public regarding potential health effects of power frequency EMFs, which are emitted by all devices carrying electricity, including electric transmission and distribution lines and substation equipment. Government officials in the U.S. and the U.K. have reviewed this issue. The U.S. National Institute of Environmental Health Sciences concluded in 2002 that, for most health outcomes, there is no evidence that EMFs cause adverse effects. The agency further noted that there is some epidemiological evidence of an association with childhood leukemia, but that the evidence is difficult to interpret without supporting laboratory evidence. The U.K. National Radiological Protection Board (part of the U.K. Health Protection Agency) concluded in 2004 that, while the research on EMFs does not provide a basis to find that EMFs cause any illness, there is a basis to consider precautionary measures beyond existing exposure guidelines. The Stakeholder Group on Extremely Low Frequency EMF, set up by the U.K. Government, has issued two reports, one in April 2007 and one in June 2010, describing options for reducing public exposure to EMF. The U.K. Government responded to the first report in 2009, agreeing to some of the proposals, including a proposed voluntary code to optimally phase 132 kilovolt overhead lines to reduce public exposure to EMF where it is cost effective to do so. The U.K. Government is currently considering the second report which concentrates on EMF exposure from distribution systems. PPL and its subsidiaries believe the current efforts to determine whether EMFs cause adverse health effects should continue and are taking steps to reduce EMFs, where practical, in the design of new transmission and distribution facilities. PPL and its subsidiaries are unable to predict what effect, if any, the EMF issue might have on their operations and facilities either in the U.S. or the U.K., and the associated cost, or what, if any, liabilities they might incur related to the EMF issue.

Environmental Matters - WPD (PPL)

 

WPD's distribution businesses are subject to environmental regulatory and statutory requirements. PPL believes that WPD has taken and continues to take measures to comply with the applicable laws and governmental regulations for the protection of the environment.

 

The U.K. Government has implemented a project to alleviate the impact of flooding on the U.K. utility infrastructure, including major electricity substations. WPD has agreed with the Ofgem to spend $46 million on flood prevention, which will be recovered through rates during the five-year period commencing April 2010. WPD is currently liaising on site-specific proposals with local offices of a U.K. Government agency.

 

U.K. legislation has been passed that imposes a duty on certain companies, including WPD, to report on climate change adaptation. The first information request was received by WPD in March 2010 and submissions for all four distribution network operators were made in June 2011. WPD has worked with other U.K. electricity network operators to undertake research with the internationally recognized U.K. Met Office (the national weather service) and to report using common agreed methodology.

 

There are no other material legal or administrative proceedings pending against or related to WPD with respect to environmental matters. See "Electric and Magnetic Fields," above, for a discussion of EMFs.

Nuclear Insurance (PPL and PPL Energy Supply)

 

PPL Susquehanna is a member of certain insurance programs that provide coverage for property damage to members' nuclear generating plants. Facilities at the Susquehanna plant are insured against property damage losses up to $2.75 billion under these programs. PPL Susquehanna is also a member of an insurance program that provides insurance coverage for the cost of replacement power during prolonged outages of nuclear units caused by certain specified conditions.

 

Under the property and replacement power insurance programs, PPL Susquehanna could be assessed retroactive premiums in the event of the insurers' adverse loss experience. At June 30, 2011, this maximum assessment was $44 million.

 

In the event of a nuclear incident at the Susquehanna plant, PPL Susquehanna's public liability for claims resulting from such incident would be limited to $12.6 billion under provisions of The Price-Anderson Act Amendments under the Energy Policy Act of 2005. PPL Susquehanna is protected against this liability by a combination of commercial insurance and an industry assessment program.

 

In the event of a nuclear incident at any of the reactors covered by The Price-Anderson Act Amendments under the Energy Policy Act of 2005, PPL Susquehanna could be assessed up to $235 million per incident, payable at $35 million per year.

 

At June 30, 2011, the property, replacement power and nuclear incident insurers maintained an A.M. Best financial strength rating of A ("Excellent").

 

Employee Relations (PPL, LKE and KU)

 

In July 2011, KU and its employees represented by the United Steelworkers of America agreed to a six-month extension of their current collective bargaining agreement, previously scheduled to expire in August 2011, which extension includes a 3% wage increase consistent with market conditions through the new expiration date. In July 2011, KU and its employees represented by IBEW Local 2100 completed annual reopener negotiations and agreed to a 3% wage increase consistent with market conditions.

Guarantees and Other Assurances

 

(PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

In the normal course of business, PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU enter into agreements that provide financial performance assurance to third parties on behalf of certain subsidiaries. Such agreements include, for example, guarantees, stand-by letters of credit issued by financial institutions and surety bonds issued by insurance companies. These agreements are entered into primarily to support or enhance the creditworthiness attributed to a subsidiary on a stand-alone basis or to facilitate the commercial activities in which these subsidiaries enter.

 

(PPL)

 

PPL fully and unconditionally guarantees all of the debt securities of PPL Capital Funding.

 

(PPL, PPL Energy Supply and LKE)

 

The table below details guarantees provided as of June 30, 2011. The total recorded liability at June 30, 2011 and December 31, 2010, was $16 million and $14 million for PPL and $11 million for both periods for LKE. Other than as noted in the descriptions for "WPD guarantee of pension and other obligations of unconsolidated entities," the probability of expected payment/performance under each of these guarantees is remote.

(a)       Represents the estimated maximum potential amount of future payments that could be required to be made under the guarantee.

(b)       PPL has provided indemnification to the purchaser of PPL Gas Utilities and Penn Fuel Propane, LLC for damages arising out of any breach of the representations, warranties and covenants under the related transaction agreement and for damages arising out of certain other matters, including certain pre-closing unknown environmental liabilities relating to former manufactured gas plant properties or off-site disposal sites, if any, outside of Pennsylvania. The indemnification provisions for most representations and warranties, including tax and environmental matters, are capped at $45 million, in the aggregate, and are triggered (i) only if the individual claim exceeds $50,000, and (ii) only if, and only to the extent that, in the aggregate, total claims exceed $4.5 million. The indemnification provisions for most representations and warranties expired on September 30, 2009 without any claims having been made. Certain representations and warranties, including those having to do with transaction authorization and title, survive indefinitely, are capped at the purchase price and are not subject to the above threshold or deductible. The indemnification provision for the tax matters representations survives for the duration of the applicable statute of limitations, and the indemnification provision for the environmental matters representations survives for a period of three years after the transaction closing. The indemnification relating to unknown environmental liabilities for manufactured gas plants and disposal sites outside of Pennsylvania could survive more than three years, but only with respect to applicable property or sites identified by the purchaser prior to the third anniversary of the transaction closing. The indemnification for covenants survives until the applicable covenant is performed and is not subject to any cap.

(c)       WPD Midlands Holdings Limited (formerly Central Networks Limited) had agreed prior to the acquisition to indemnify certain former directors of a Turkish entity in which WPD Midlands Holdings Limited previously owned an interest for any liabilities that may arise as a result of an investigation by Turkish tax authorities, and PPL WEM has received a cross-indemnity from E.ON AG with respect to these indemnification obligations. Additionally, PPL subsidiaries agreed to provide indemnifications to subsidiaries of E.ON AG for certain liabilities relating to properties and assets owned by affiliates of E.ON AG that were or are to be transferred to WPD Midlands in connection with the acquisition. The maximum exposure and expiration of these indemnifications cannot be estimated because the maximum potential liability is not capped by and there is no expiration date in the transaction documents.

(d)       In connection with the liquidation of wholly owned subsidiaries that have been deconsolidated upon turning the entities over to the liquidators, certain affiliates of PPL Global have agreed to indemnify the liquidators, directors and/or the entities themselves for any liabilities or expenses arising during the liquidation process, including liabilities and expenses of the entities placed into liquidation. In some cases, the indemnifications are limited to a maximum amount that is based on distributions made from the subsidiary to its parent either prior or subsequent to being placed into liquidation. In other cases, the maximum amount of the indemnifications is not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases in which the agreements provide for a specific limit on the amount of the indemnification, and the expiration date was based on an estimate of the dissolution date of the entities.

 

       In connection with their sales of various businesses, WPD and its affiliates have provided the purchasers with indemnifications that are standard for such transactions, including indemnifications for certain pre-existing liabilities and environmental and tax matters. In addition, in connection with certain of these sales, WPD and its affiliates have agreed to continue their obligations under existing third-party guarantees, either for a set period of time following the transactions or upon the condition that the purchasers make reasonable efforts to terminate the guarantees. Finally, WPD and its affiliates remain secondarily responsible for lease payments under certain leases that they have assigned to third parties.

(e)       As a result of the privatization of the utility industry in the U.K., certain electric associations' roles and responsibilities were discontinued or modified. As a result, certain obligations, primarily pension-related, associated with these organizations have been guaranteed by the participating members. Costs are allocated to the members based on predetermined percentages as outlined in specific agreements. However, if a member becomes insolvent, costs can be reallocated to and are guaranteed by the remaining members. At June 30, 2011, WPD has recorded an estimated discounted liability based on its current allocated percentage of the total expected costs for which the expected payment/performance is probable. Neither the expiration date nor the maximum amount of potential payments for certain obligations is explicitly stated in the related agreements. Therefore, they have been estimated based on the types of obligations.

(f)       Two WPD unconsolidated affiliates were refinanced during 2005. Under the terms of the refinancing, WPD has indemnified the lender against certain tax and other liabilities.

(g)       Other than the letters of credit, all guarantees of PPL Energy Supply, on a consolidated basis, also apply to PPL on a consolidated basis for financial reporting purposes.

(h)       Standby letter of credit arrangements under PPL Energy Supply's credit facilities for the purposes of protecting various third parties against nonperformance by PPL. This is not a guarantee by PPL on a consolidated basis.

(i)       PPL Susquehanna is contingently obligated to pay this amount related to potential retrospective premiums that could be assessed under its nuclear insurance programs. See "Nuclear Insurance," above for additional information.

(j)       This is the maximum amount PPL Susquehanna could be assessed for each incident at any of the nuclear reactors covered by this Act. See "Nuclear Insurance," above for additional information.

(k)       PPL Energy Supply's maximum exposure with respect to certain indemnifications and the expiration of the indemnifications cannot be estimated because, in the case of certain indemnification provisions, the maximum potential liability is not capped by the transaction documents and the expiration date is based on the applicable statute of limitations. The exposure and expiration dates noted are only for those cases in which the agreements provide for specific limits.

 

       A subsidiary of PPL Energy Supply has agreed to provide indemnification to the purchaser of the Long Island generation business for damages arising out of any breach of the representations, warranties and covenants under the related transaction agreement and for damages arising out of certain other matters, including liabilities relating to certain renewable energy facilities which were previously owned by one of the PPL subsidiaries sold in the transaction but which were unrelated to the Long Island generation business. The indemnification provisions are subject to certain customary limitations, including thresholds for allowable claims, caps on aggregate liability, and time limitations for claims arising out of breaches of most representations and warranties.

 

       A subsidiary of PPL Energy Supply has agreed to provide indemnification to the purchasers of the Maine hydroelectric facilities for damages arising out of any breach of the representations, warranties and covenants under the respective transaction agreements and for damages arising out of certain other matters, including liabilities of the PPL Energy Supply subsidiary relating to the pre-closing ownership or operation of those hydroelectric facilities. The indemnification obligations are subject to certain customary limitations, including thresholds for allowable claims, caps on aggregate liability, and time limitations for claims arising out of breaches of representations and warranties. The indemnification provisions for certain representations and warranties expired in the second quarter of 2011.

 

       Subsidiaries of PPL Energy Supply have agreed to provide indemnification to the purchasers of certain non-core generation facilities sold in March 2011 (see Note 8 for additional information) for damages arising out of any breach of the representations, warranties and covenants under the related transaction agreements and for damages arising out of certain other matters relating to the facilities that were the subject of the transaction, including certain reduced capacity payments (if any) at one of the facilities in the event specified PJM rule changes are proposed and become effective. The indemnification provisions are subject to certain customary limitations, including thresholds for allowable claims, caps on aggregate liability, and time limitations for claims arising out of breaches of most representations and warranties.

(l)       In December 2007, a subsidiary of PPL Energy Supply executed revised owners agreements for two jointly owned facilities, the Keystone and Conemaugh generating stations. The agreements require that in the event of any default by an owner, the other owners fund contributions for the operation of the generating stations, based upon their ownership percentages. The maximum obligation among all owners, for each station, is currently $20 million. The non-defaulting owners, who make up the defaulting owner's obligations, are entitled to the generation entitlement of the defaulting owner, based upon their ownership percentage. The agreements do not have an expiration date.

(m)       A PPL Energy Supply subsidiary owned a one-third equity interest in Safe Harbor Water Power Corporation (Safe Harbor) that was sold in March 2011. Beginning in 2008, PPL Energy Supply guaranteed one-third of any amounts payable with respect to certain senior notes issued by Safe Harbor. Under the terms of the sale agreement, PPL Energy Supply continues to guarantee the portion of Safe Harbor's debt, but received a cross-indemnity from the purchaser in the event PPL Energy Supply is required to make a payment under the guarantee. Exposure noted reflects principal only. See Note 8 for additional information on the sale of this interest.

(n)       All guarantees of LKE, on a consolidated basis, also apply to PPL on a consolidated basis for financial reporting purposes.

(o)       LKE provides certain indemnifications, the most significant of which relate to the termination of the WKE lease in July 2009. These guarantees cover the due and punctual payment, performance and discharge by each party of its respective present and future obligations. The most comprehensive of these guarantees is the LKE guarantee covering operational, regulatory and environmental commitments and indemnifications made by WKE under the WKE Transaction Termination Agreement. This guarantee has a term of 12 years ending July 2021, and a cumulative maximum exposure of $200 million. Certain items such as non-excluded government fines and penalties fall outside the cumulative cap. Another guarantee with a maximum exposure of $100 million covering other indemnifications expires in 2023. Certain matters are currently under discussion among the parties, including one matter currently in arbitration and a further matter for which LKE is contesting the applicability of the indemnification requirement, the outcomes of which cannot be predicted at this time. Additionally, LKE has indemnified various third parties related to historical obligations for other divested subsidiaries and affiliates. The indemnifications vary by entity and the maximum amount limits range from being capped at the sale price to no specified maximum; however, LKE is not aware of formal claims under such indemnities made by any party at this time. LKE could be required to perform on these indemnifications in the event of covered losses or liabilities being claimed by an indemnified party. No additional material loss is anticipated by reason of such indemnification.        

 

(PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

 

PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU and their subsidiaries provide other miscellaneous guarantees through contracts entered into in the normal course of business. These guarantees are primarily in the form of indemnification or warranties related to services or equipment and vary in duration. The amounts of these guarantees often are not explicitly stated, and the overall maximum amount of the obligation under such guarantees cannot be reasonably estimated. Historically, PPL and its subsidiaries have not made any significant payments with respect to these types of guarantees and the probability of payment/performance under these guarantees is remote.

 

PPL, on behalf of itself and certain of its subsidiaries, maintains insurance that covers liability assumed under contract for bodily injury and property damage. The coverage requires a maximum $4 million deductible per occurrence and provides maximum aggregate coverage of $200 million. This insurance may be applicable to obligations under certain of these contractual arrangements.
