(a)Included in Property, plant and equipment, net as of December 31, 2013, on the Consolidated Balance Sheets.
(b) Includes Lee Units 1 and 2. Excludes 170 MW Lee Unit 3 that is expected to be converted to gas in 2014. Duke Energy Carolinas expects to retire or convert these units by December 2020 in conjunction with a settlement agreement associated with the Cliffside Unit 6 air permit.
(c)Includes Crystal River Units 1 and 2.
(d)Includes Beckjord Units 4 through 6 and Miami Fort Unit 6. 150 MW Beckjord Station Unit 4 was retired on February 17, 2014. Beckjord units have no remaining book value.
(e)Includes Wabash River Units 2 through 6. Wabash River Unit 6 is being evaluated for potential conversion to gas. Duke Energy Indiana committed to retire or convert these units by June 2018 in conjunction with a settlement agreement associated with the Edwardsport air permit.
                   
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.
