Kilroot — During 2015, the Company tested the recoverability of long-lived assets at Kilroot, a coal- and oil-fired plant in the U.K., when the regulator established lower capacity prices for the Irish Single Electricity Market. The Company determined that the carrying amount of the asset group was not recoverable. The Kilroot asset group was determined to have a fair value of $70 million using the income approach. As a result, the Company recognized asset impairment expense of $121 million. Kilroot is reported in the Europe SBU reportable segment.

Buffalo Gap III — During 2015, the Company tested the recoverability of its long-lived assets at Buffalo Gap III, a wind farm in Texas. Impairment indicators were identified based on a decline in forward power curves coupled with the near term expiration of favorable contracted cash flows. The Company determined that the carrying amount was not recoverable. The Buffalo Gap III asset group was determined to have a fair value of $118 million using the income approach. As a result, the Company recognized asset impairment expense of $116 million. Buffalo Gap III is reported in the US SBU reportable segment.

U.K. Wind (Development Projects) — During 2015, the Company decided to no longer pursue two wind projects in the U.K. based on recent regulatory clarifications specific to these projects, resulting in a full impairment. Impairment indicators were also identified at four other wind projects based on their current development status and a reassessment of the likelihood that each project would be pursued given aviation concerns, regulatory changes, economic considerations and other factors. The Company determined that the carrying amounts of each of these asset groups, which totaled $38 million, were not recoverable. In aggregate, the asset groups were determined to have a fair value of $1 million using the market approach and, as a result, the Company recognized asset impairment expense of $37 million. The U.K. Wind (Development Projects) are reported in the Europe SBU reportable segment.

Ebute — During 2014, the Company identified impairment indicators at Ebute in Nigeria, resulting from the continued lack of gas supply, the increased likelihood of selling the asset group before the end of its useful life, and indications about the potential proceeds that could be received from a future sale. The Company determined that the carrying amount of the asset group was not recoverable. The Company recognized asset impairment of $67 million, which represents the difference between the carrying amount of $103 million and fair value less cost to sell of $36 million. In November 2014, the Company completed the sale of its interest in Ebute. See Note 24—Dispositions for additional details. Prior to its sale, Ebute was reported in the Europe SBU reportable segment.

U.K. Wind (Newfield) — During 2014, the Company tested the recoverability of long-lived assets at its Newfield wind development project in the U.K. after their government refused to grant a permit necessary for the project to continue. The Company determined that the carrying amount of the asset group was not recoverable. The Newfield asset group was determined to have no fair value using the income approach. As a result, the Company recognized asset impairment expense of $12 million. U.K. Wind (Newfield) is reported in the Europe SBU reportable segment.

East Bend (DP&L) — During 2014, the Company identified impairment indicators at East Bend, a coal-fired plant in Ohio jointly owned by DP&L, resulting from the increased likelihood that the asset group would be disposed prior to the end of its useful life. The Company determined that the carrying amount of the asset group was not recoverable. The East Bend asset group was determined to have a fair value of $2 million using the market approach, and the Company recognized asset impairment expense of $12 million. The Company's interest in East Bend was sold in December 2014. Prior to its sale, East Bend was reported in the US SBU reportable segment.

Beaver Valley — During 2013, Beaver Valley, a wholly-owned coal-fired plant in Pennsylvania, entered into an agreement to early terminate its PPA with the offtaker in exchange for a lump-sum payment of $60 million. The termination of the PPA resulted in a significant reduction in the future cash flows of the asset group and was considered an impairment indicator. The carrying amount of the asset group was not recoverable. The carrying amount of the asset group exceeded the fair value of the asset group, resulting in asset impairment expense of $46 million. Beaver Valley is reported in the US SBU reportable segment.

Conesville (DP&L) — During 2013, the Company tested the recoverability of long-lived assets at Conesville, a coal-fired plant in Ohio jointly-owned by DP&L. Gradual decreases in power prices as well as lower estimates of future capacity prices in conjunction with the DP&L reporting unit failing Step 1 of the annual goodwill impairment test were determined to be impairment indicators. The Company performed a long-lived asset impairment test and determined that the carrying amount of the asset group was not recoverable. The Conesville asset group was determined to have zero fair value using discounted cash flows under the income approach. As a result, the Company recognized asset impairment expense of $26 million. Conesville is reported in the US SBU reportable segment.

Itabo (San Lorenzo) — During 2013, the Company tested the recoverability of long-lived assets at San Lorenzo, a LNG fueled plant of Itabo. Itabo was informed by Super-Intendencia de Electridad ("SIE"), the system regulator in the Dominican Republic, that it would not receive capacity revenue going forward. This communication in combination with current adverse market conditions were determined to be an impairment indicator. The Company performed a long-lived asset impairment test considering different scenarios and determined that, based on undiscounted cash flows, the carrying amount of San Lorenzo was not recoverable. The fair value of San Lorenzo was determined using the market approach based on a broker quote and it was determined that its carrying amount of $23 million exceeded the estimated fair value of $7 million. As a result, the Company recognized asset impairment expense of $16 million. Itabo is reported in the MCAC SBU reportable segment.
