Supporting Our Communities

DP&L and our employees have a long tradition of supporting the Miami Valley. The Dayton Power and Light Company Foundation reinvests in our communities and contributes to the overall quality of life. The DP&L Foundation annually donates more than $1 million to a variety of civic, cultural and youth organizations, with a particular emphasis on those that have an educational focus.

Regional Investments

By testing renewable energy sources, installing solar arrays and restoring natural prairie lands, we can make our region a cleaner, more environmentally-friendly place for us all.

Reliable Power

DP&L consistently exceeds reliability standards set by the Public Utilities Commission of Ohio. We are a member of the 13-state Regional Transmission Organization, PJM, that coordinates the movement of wholesale electricity and manages the high-voltage electric grid. For safety and reliability, Ohio and Federal regulations mandate tree trimming near power lines. DP&L trims trees along 2,100 miles of overhead distribution power lines per year on average.

With DP&L, tomorrow starts today.
