Rolling Hills Generating Station Receives Wastewater Discharge Permit

Planned Combined-cycle and Peaking Facility Positioned to Fill Future PJM Need

Wilkesville, Ohio—Rolling Hills Generating Station near Wilkesville in Vinton County, Ohio, has received its National Pollutant Discharge Elimination System (NPDES) wastewater permit for a planned conversion of the facility from a peaking facility to a combined-cycle and peaking facility.

The State of Ohio Environmental Protection Agency (EPA) issued the wastewater permit on Feb. 17.

“Safety, including protecting the environment, is an important priority,” said Jeff James, project manager. “Ohio EPA’s approval of the Rolling Hills Generating Station wastewater discharge permit is a significant milestone in our plan to convert the facility to a combined-cycle and peaking plant. As aging coal plants are retired, we anticipate that this strategically located plant will increasingly be called upon by PJM to meet additional baseload power requirements in this region.”

Rolling Hills Generating Station, in operation since 2003, is an 850-megawatt (MW), natural gas-fueled peaking power plant that is being converted to a 1,414-MW combined-cycle and peaking facility. The conversion is planned as a result of a resurgence among industry and manufacturing in the U.S. and a number of anticipated coal plant retirements in the PJM Interconnection market. Both market factors could increase the need for natural gas-fueled power generation.

Additionally, facilities such as the converted Rolling Hills combined-cycle configuration will help Ohio to meet the U.S. Environmental Protection Agency’s proposed Clean Power Plan greenhouse gas emissions goal. Market need will ultimately determine the timeline for the project. The earliest construction is expected to begin is in 2015, with commercial operation commencing three years after the start of construction.

The Rolling Hills project received a Certificate of Environmental Compatibility and Public Need from the State of Ohio Siting Board in 2013. The project is expected to receive its Prevention of Significant Deterioration (PSD) air quality permit within the next few weeks.
