Dayton Power & Light Seeks Bids for Renewable Energy

DAYTON, Ohio, July 25th, 2008 – Dayton Power & Light Company (DP&L), a subsidiary of DPL Inc. (NYSE: DPL), has issued a request for proposals (RFP) for renewable energy resources.

“DP&L is taking this initial step to expand our portfolio of generation to include renewable energy resources,” said Paul Barbas, DPL president and chief executive officer.  “Our goal, as it has always been, is to act in an environmentally responsible and compliant manner while controlling costs for our customers.  Soliciting competitive bids to meet our renewable needs should help drive the development of economically viable renewable alternatives.”

In keeping with the recently passed Ohio energy legislation, Ohio Amended Substitute Senate Bill 221 (S.B. 221), DP&L is seeking a minimum of 38,000 megawatt-hours (MWh) of energy from renewable energy resources by the end of 2009.  Six hundred twenty five (625) MWh of this energy is to include solar photovoltaic or solar thermal energy.  Within cost limits set forth in the bill, these requirements will continue to grow to an approximate need of 552,000 MWh of renewable energy resources by the end of 2015, which includes approximately 24,000 MWh of solar energy.  In selecting bids, DP&L will consider the requirement that at least 50% of its renewable energy come from within the state.

Renewable energy resources, as defined by S.B. 221, include wind, solar, hydro, geothermal, and fuel derived from solid waste.  The Public Utilities Commission of Ohio (PUCO) will soon issue proposed rules related to alternative energy portfolio standards.  DP&L reserves the right to modify its RFP based on the PUCO rules.

All proposals submitted in response to this RFP must be received by DP&L no later than September 12, 2008.  Complete RFP information can be found at www.dplinc.com/renewablerfp.pdf.
