DP&L Plans to Retire Six Coal Units

LCG, May 16, 2013--Dayton Power & Light (DP&L), a subsidiary of AES Corp., announced earlier this week plans to retire six, coal-fired power generating units by June 2015. The retirements, totaling nearly 600 MW of electric generating capacity, are driven by existing and expected environmental regulations, including the Mercury and Air Toxics Standards (MATS).

DP&L will retire five units with a combined capacity of approximately 390 MW at its 414-MW Hutchings facility in Miamisburg, Ohio, by June 2015. The aging units were commissioned between 1948 and 1953. Hutchings Unit 4, which has a damaged turbine, will be retired next month.

A sixth coal-fired unit, co-owned with Duke Energy Ohio, will also be retired by June 2015. DP&L's share is approximately 207 MW of Beckjord Unit 6. DP&L currently does not plan to replace the units to be retired.

Another AES subsidiary, Indianapolis Power & Light Co.(IPL), also recently announced plans to retire a total of approximately 600 MW of coal-fired units, including four at its Eagle Valley Generating Station and four at the Harding Street Generating Station, where switching from coal to natural gas is under consideration. The retirements are again driven by the Environmental Protection Agency's (EPA's) new MATS regulations.
