NEW YORK (Standard&Poor's) July 28, 2009--Standard&Poor's Ratings Services today affirmed its 'AAA/A-1+' ratings on eight Exelon Generation Co. LLC jointly-supported bond issues and removed the ratings from CreditWatch with negative implications (see list). The ratings on the eight affected issues are based on the joint credit support provided by Exelon Generation Co. LLC ('BBB/A-2') and either Wachovia Bank N.A. ('AA/A-1+') or BNP Paribas ('AA/A-1+'). These entities provide both credit and liquidity support for the full and timely payment of interest and principal. Today's rating actions follow the July 22, 2009, affirmation of our 'BBB/A-2' rating on Exelon Generation Co. LLC and our removal of that rating from CreditWatch negative, where it was placed Oct. 21, 2008.
