Carroll County Energy LLC is working at PJM Interconnection on needed clearances to interconnect its 742-MW, gas-fired project in Ohio to the grid.
The company proposes to install PJM queue project #Y2-050, a 742 MW (672 MW capacity) natural gas-fired 2×1 F class combined cycle plant, said a November 2013 system impact study from PJM. The proposed point of interconnection is located approximately 17 miles from the Canton Central station on the Canton Central-Tidd 345-kV line. The location of the generating facility site is in Carroll County, Ohio, approximately 0.75 miles from the proposed 345-kV switching station.
The requested in-service date for the power project is Aug. 31, 2017.
The objective of the impact study is to determine budgetary cost estimates and approximate construction timelines for identified transmission facilities required to connect the proposed generating facilities to the American Electric Power (NYSE: AEP) transmission system. This project entered the PJM project queue in August 2012 and is still several steps short of PJM approval, including the working out of an Interconnection Service Agreement.
The company also has a November 2013 siting application pending at the Ohio Power Siting Board, which plans a March 6 local public hearing on the project and a March 13 adjudicatory hearing at the board’s offices in Columbus, Ohio.
This project is scheduled for commencement of commercial operation by May 2017 in order to meet the anticipated summer peak load demands within the PJM marketplace. In order to meet this schedule, Carroll County Energy is requesting issuance of an Ohio Power Siting Board site certificate by April 2014 to support commencement of construction in February 2015, the company said in the November 2013 application filed with the board.
Carroll County Energy is within the organizational structure of Advanced Power AG, an international developer of independent power projects. The management of Advanced Power has led the development of over 13,500 MW of power projects worldwide.
“The Facility will help meet energy demand in the region, particularly in light of the retirement of aging generating capacity, with the retirement of 6.3 gigawatts (GW) of capacity announced for retirement in Ohio before 2016,” the application said about mostly coal-fired capacity. “The Facility will help meet this need by providing additional base load and peaking capacity via its natural gas-fired combined-cycle technology.”
The facility will utilize two General Electric (GE) 7F 5-Series natural gas turbines, each with a heat recovery steam generator (HRSG), and a single GE steam turbine generator (STG). The facility will have a nominal net output of 742 MW (full duct fired operation with inlet air cooling at 59°F ambient temperature). The facility’s fuel will be natural gas supplied from the existing Tennessee Gas Pipeline system, owned by Kinder Morgan Energy Partners.
The Ohio Environmental Protection Agency in November 2013 issued a final air permit-to-install to Carroll County Energy for this project.
