Gemma Power Systems gains EPC contract on West Virginia CCGT project

Gemma Power Systems will oversee construction of a 625-MW natural gas-fired power plant in Harrison County, West Virginia.

Gemma, a subsidiary of Argan Inc., entered into a contract with ESC Harrison County Power LLC for engineering, procurement and construction services at the plant. The Harrison County Power Project is a planned combined-cycle facility which will include a GE 7HA.02 combustion turbine generator connected to a heat recovery steam generator.

When operating, the plant will provide enough power for approximately 425,000 homes through the PJM interconnection. Construction for the facility is scheduled to begin in the summer with completion scheduled in 2022.

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

Caithness Energy, L.L.C partnered with Energy Solutions Consortium, LLC (“ESC”) to develop the project.

“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 kW of any recent project in the region,” said Ross Ain, President of Caithness.
