DPL SETS NEW RECORD PEAK ELECTRIC DEMAND

DAYTON, Ohio, August 8, 2007 – DPL Inc.’s (NYSE: DPL) principal subsidiary, The Dayton Power and Light Company, set a new record for electric peak demand today of approximately 3,300 megawatts, surpassing the previous record of 3,243 megawatts set on July 25, 2005.

“Our planning process takes into consideration the potential for extreme temperatures like we are experiencing this week,” said Paul Barbas, President and Chief Executive Officer of DPL Inc. “System reliability is an ongoing focus throughout the company. Our employees are monitoring our system and regional conditions around the clock. And, the investments we make in our system year to year support our mission to deliver reliable service to our customers irrespective of weather conditions.”

The record demand is being driven by the extended period of mid-90 degree heat and high humidity.  DPL encourages customers to use energy wisely throughout the year and especially in periods of increased demand.  By taking a few simple steps, customers can reduce their energy usage, lessening the impact of extreme temperatures.

“Most importantly, we encourage everyone to take the necessary precautions to stay safe during this intense heat,” concluded Barbas.

Energy Saving Tips from DP&L

·For homes with air conditioning, set the thermostat to the highest comfortable temperature.  Raising the thermostat by 1 degree can save 2% in cooling costs.

·Make sure air conditioning units are clean and well-maintained to ensure the most efficient use of energy.

·Keep blinds and drapes closed on windows during the day.

·Avoid using the stove and humidity producing appliances, like dishwashing, when possible.

·Turn off unnecessary lights.  They add to the heat in the home.  Consider switching to cooler, energy-efficient fluorescent bulbs.

·Use ceiling fans and portable floor fans to move the air around in the home. Make sure ceiling fans are blowing down.  Fans should turn counter-clockwise in summer.  If the home does not have air conditioning, fans are essential for cooling.  In homes with air conditioning, fans enable residents to raise the thermostat and save energy without affecting comfort.
