Gemma Power wins EPC contract to build 625MW power plant in West Virginia

WCN Editorial Team 20 May 2019 NORTH AMERICA ENERGY & UTILITIES

Gemma Power Systems, a subsidiary of Argan, has secured an engineering, procurement and construction (EPC) contract from ESC Harrison County Power to build a 625MW natural gas-fired power plant in Harrison County, West Virginia.

The Harrison County Power Project will generate enough electricity to power about 425,000 homes, transmitted through the PJM interconnect grid.

Caithness Energy partnered with Energy Solutions Consortium (ESC) to develop the project.

The project is a combined-cycle facility which will be powered by a GE7HA.02 combustion turbine generator (CTG), connected to a heat recover steam generator (HRSG).

The HRSG will harness the exhaust heat from the CTG to produce superheated steam, which will drive a steam turbine to generate electricity in a clean and efficient manner. An air-cooled condenser (ACC) at the plant is expected to reduce the usage of water to less than 3%, for a similar sized facility.

Gemma Power Systems CEO William Griffin, Jr., said “We are thrilled to have the opportunity to help deliver cleaner, reliable energy to Harrison County and the greater West Virginia community.”

Gemma stated that it has received a limited notice to proceed with the project planning and engineering activities. The facility’s construction is scheduled to begin this summer and is expected to be completed in 2022.

Caithness president Ross Ain said: “Caithness has selected Gemma to construct this important project for a number of reasons. Gemma recently completed our 1,080 MW Freedom natural gas-fired power plant which was constructed for the lowest cost per installed kilowatt of any recent project in the region.

“Gemma has been a good member of the local communities in which it does business. Gemma also has maintained an excellent safety record in constructing these plants. We believe Gemma will serve the project and the community well in this large undertaking.”

When completed, the facility is expected to use up to $111m of natural gas annually, while hundreds of jobs are created in the region.

About 2,453 jobs will be created during the construction phase. When operational, the plant will create about 30 full-time jobs and 714 jobs in terms of requirements for maintenance, suppliers and other needed local services.

The project will also generate indirect economic benefits to the local community, including $880m in overall construction.
