Business Editors

DAYTON, Ohio--(BUSINESS WIRE)--June 21, 2000

DPL Inc. (NYSE:DPL) today announced that it has completed the process to obtain approval from the Public Utilities Commission of Ohio (PUCO) for its Customer Choice transition plan. Labeled one of the most progressive in the country, the DPL plan provides both the customer and the Company the opportunity to move quickly to a competitive generation supply market.

The transition plan filing is a requirement of the Ohio legislation passed in July 1999 that will deregulate the Ohio electric utility industry beginning January 1, 2001. DPL reached agreement with major groups participating in the filing, including the Staff of the PUCO, prior to yesterday's conclusion of the hearing process. Final PUCO approval of the DPL plan is expected in the third quarter.

"Since Ohio electric restructuring legislation was passed less than a year ago, we have moved aggressively and swiftly to put in place the elements needed to take advantage of the new competitive world," said Allen Hill, President and CEO of DPL Inc. "The DPL plan is an ideal complement to our business strategy and enhances our ability to reach a new growth plateau."

The DPL transition plan which begins in January provides a three-year transition period ending December 31, 2003, at which time DPL's generation business unit will be fully deregulated. The plan also provides the organizational and financial flexibility for the Company to continue its corporate realignment initiatives. DPL functionally separated its generation, transmission, and distribution business units and has announced the sale of its natural gas retail distribution operations.

The following groups have signed the transition plan agreement: The Staff of the PUCO; The Office of the Ohio Consumers' Counsel; The Ohio Manufacturers' Association; Industrial Energy Users - Ohio; Ohio Council of Retail Merchants; American Municipal Power-Ohio; WPS Energy Services, Inc.; Exelon Energy; The Association for Hospitals and Health Systems, the Ohio Hospital Association; New Energy Midwest, L.L.C.; Columbia Energy Services Corporation; Columbia Energy Power Marketing Corporation; Strategic Energy, L.L.C.; Supporting Council of Preventative Effort (SCOPE); Montgomery County Prosecutors' Office; Ohio Department of Development; Ohio Partners for Affordable Energy; Buckeye Power, Inc.; and Ohio Rural Electric Cooperatives, Inc.
