11 May 2010-- Exelon Power will retire Unit 2 at both the Cromby and Eddystone cosl-fired power plants in Pennsylvania sooner than previously announced because of a revised analysis from the PJM Interconnection.

PJM's analysis showed that transmission system upgrades can be completed sooner than the original analysis indicated, which will allow the coal-fired units to retire earlier.

PJM determined that Cromby must remain in operation until Dec. 31, 2011, almost a year earlier than planned. The Eddystone unit can remain in operation until Dec. 31, 2012, a full year earlier, to support transmission system reliability.

Exelon announced in 2009 would retire the two units for economic reasons, but agreed to extend operations for system reliability reasons.
