OPSB approves Rolling Hills Facility Expansion in Vinton County

COLUMBUS, OHIO (May 1, 2013) – The Ohio Power Siting Board (OPSB) today authorized Rolling Hills Generating, LLC (Case No. 12-1669-EL-BGA) to increase the capacity of its existing natural gas-fired electric generating facility in Wilkesville, Ohio from 860 megawatts (MW) to 1,414 MW. 

To achieve this capacity increase, Rolling Hills will convert four of the facility’s five existing combustion turbines from simple-cycle to combined-cycle mode.  Upon completion, Rolling Hills will use the upgraded turbines to serve intermediate or base load power demands and continue to use the remaining simple-cycle turbine to provide electric peaking power to the wholesale power market.   

On June 1, 2012, Rolling Hills filed an application for an amendment of a Certificate of Environmental Compatibility and Public Need for the Rolling Hills Generating Station Combined-Cycle Conversion project.  On Jan. 14, 2013, the OSPB staff filed a report of investigation regarding the project.  An agreement was filed between Rolling Hills and the OPSB staff on Feb. 4, 2013.

The Board’s order today authorizes the changes to the facility, subject to 19 conditions, as well as the conditions outlined in the original certificate granted by the Board in 2001.
