The Ohio Environmental Protection Agency on Nov. 5 issued a final air permit-to-install to Carroll County Energy LLC for a 742 MW (nominal) gas-fired combined-cycle plant to be built in Washington Township of Carroll County.
The facility would include two General Electric 7FA combined cycle combustion turbines (each 2,045mmBtu/hr heat input turbine at ISO conditions and 566mmBtu/hr heat input duct burner, HHV) with dry low NOx combustors, selective catalytic reduction and catalytic oxidizers for emissions control.
Carroll County Energy on Aug. 7 filed a pre-application notice with the Ohio Power Siting Board that it plans to build a 700-MW, gas-fired combined-cycle power plant in Carroll County. The project as of Nov. 6 was still in the pre-application stage, with a full siting application eventually needed.
“The proposed 700 MW combined cycle generation facility will be powered by natural gas and will be located on approximately 77 acres of privately owned land which is adjacent to a 23 acre site available for construction lay down,” said the brief Aug. 7 notice. “The site will be in Washington Township, Carroll County, Ohio with access off of State Route 9 and will be located near an [American Electric Power] 345 KV transmission line.”
The notice added: “The proposed project will utilize two General Electric 7 FA Series 5 gas combustion turbine generators each with a heat recovery steam generator (HRSG), and a single steam turbine generator.”
Carroll County Energy Project Manager Jonathan Winslow has told GenerationHub that he expects construction on the estimated $800m project to start in mid-2015. Winslow is also director of development for Advanced Power Services (NA). Advanced Power Services is a leading energy development company based in Boston, Mass.
