PJM issues new impact study on 685-MW ESC Brooke County project in W.Va.

ESC Brooke County Power I LLC has proposed a combined-cycle generating facility located approximately 10.4 miles south of the Wylie Ridge substation on the Tidd-Wylie Ridge 345 kV line located in Brooke County, West Virginia.

PJM Interconnection has issued a revised System Impact Study on the project dated August 2016, which updates an April 2016 version of the study. The intent of the System Impact Study is to determine a plan, with approximate cost and construction time estimates, to connect the subject generation interconnection project to the PJM network at a location specified by ESC Brooke County.

The installed facilities will have a total capability of 685 MW with 685 MW of this output being recognized by PJM as capacity. The proposed in-service date for this project is June 1, 2020. This study does not imply a Monongahela Power commitment to this in-service date. This project, under PJM queue #AA2-121, will interconnect to the Mon Power transmission system through a new three breaker ring bus station on the Tidd-Wylie Ridge 354 kV line. Project AA2-121 was studied with a commercial probability of 100%.

ESC Brooke County Power I applied in March with the West Virginia Department of Environmental Protection for an air permit allowing it to construct, install, and operate this natural gas- and ethane-fueled combined-cycle combustion turbine (CT) plant. The project site is located in Follansbee, Brooke County, West Virginia. The site is zoned for industrial use. This project would have a nominal gross electrical generating capacity of 750 MW, the permit application shows.

The emission sources associated with the project are:

  • Two General Electric Frame 7HA.01 combustion turbines (CTs), fueled by natural gas (raw or pipeline quality), ethane, or a blend of these fuels;
  • Two Heat Recovery Steam Generators (HRSGs), one for each CT;
  • One Auxiliary Boiler with a maximum heat input of 111.9 million British Thermal Units per hour (MMBtu/hr), burning natural gas (raw or pipeline quality), ethane, or a blend of these fuels;
  • One Fuel Gas Heater with a maximum heat input of 5.4 MMBtu/hr, burning natural gas (raw or pipeline quality), ethane, or a blend of these fuels;
  • One 2,000 kW diesel Emergency Generator fueled by ultra-low sulfur diesel (ULSD) fuel;
  • One 315 horsepower (hp) emergency diesel Fire Water Pump fueled by ULSD;
  • One wet, mechanical draft Cooling Tower; and
  • Diesel fuel, lubricating oil, and aqueous ammonia storage tanks.

ESC said in the application that it wishes to obtain WVDEP air permit approval by October 2016 to provide sufficient time for equipment ordering, fabrication, construction, and installation, and achieve commercial operation in June 2020.

A company logo in the air permit application shows this is a project of Energy Solutions Consortium LLC, which says on its website that it is focused on developing gas-based projects in Appalachia.
