NEW YORK (Standard&Poor's) Feb. 5, 2007--Standard&Poor's Ratings Services said today that it raised its corporate credit ratings on DPL Inc. and its regulated subsidiary, Dayton Power&Light Co., to 'BBB' from 'BB+'. The outlook is stable. Dayton, Ohio-based DPL has about $1.7 billion of debt outstanding. "The upgrade incorporates the prospect for continued improvement in the consolidated financial profile with further debt reduction and greater utility cash flow," said Standard&Poor's credit analyst Todd Shipman.

Ratings stability for DPL is premised on full implementation of its strategy
