Duke Energy Carolinas has committed to retire 1,667 MW in conjunction with a Cliffside air permit settlement, of which 587 MW have already been retired as of March 31, 2013. Duke Energy Carolinas retired 710 MW for Riverbend Units 4 through 7 and Buck Units 5 and 6 on April 1, 2013. Excludes 170 MW Lee Unit 3 that is expected to be converted to gas in 2014. The Lee Unit 3 conversion will be considered a retirement toward meeting the 1,667 MW retirement commitment. | | (c) | Includes Sutton Station, which is expected to be retired by the end of 2013. | | (d) | Includes Crystal River Units 1 and 2. | | (e) | Net book value of Duke Energy Carolinas' Buck Units 5 and 6 of $68 million, and Duke Energy Progress' Sutton Station of $62 million is included in Generation facilities to be retired, net, on the Condensed Consolidated Balance Sheets at March 31, 2013. | | (f) | Includes Beckjord Station Units 2 through 6 and Miami Fort Unit 6. Beckjord has no remaining book value. Beckjord Unit 1 was retired May 1, 2012. | | (g) | Includes Wabash River Units 2 through 6. | | | | | | | | | | | | | | | | | | | | | | Duke Energy continues to evaluate the potential need to retire these coal-fired generating facilities earlier than the current estimated useful lives, and plans to seek regulatory recovery for amounts that would not be otherwise recovered when any of these assets are retired. However, such recovery, including recovery of carrying costs on remaining book values, could be subject to future regulatory approvals and therefore cannot be assured. | | | | | | | | | | | | | | | | | | | | |
