He earned his bachelor of science degree in chemical engineering from Cornell University. Porter and his family will relocate to the Dayton area from Panama this year. He will continue DPL’s practice of executive involvement in issues and organizations critical to the future of the Miami Valley region.

Competitive Generation led by Herrington in his role as chief operating officer of the U.S. Strategic Business Unit will be headquartered in Dayton. Herrington will remain based in Dayton.

Before coming to DPL in 2012, Herrington was president of Global Wind Generation for AES, managing the company’s wind generation portfolio. Prior to that, he held leadership positions in a global energy company in California which ran competitive power generation businesses with assets in coal, natural gas and wind.
