Gemma Power Systems says it completed construction of Competitive Power Venture’s (CPV) Towantic Energy Center, a 785 MW combined-cycle electric generating facility in Oxford, Connecticut.

The CPV Towantic Energy Center is a 2 × 1 combined-cycle project composed of two General Electric 7HA.01 combustion turbine generators, two heat recovery steam generators and one steam turbine generator. The facility is primarily fueled by clean natural gas. Substantial completion was achieved on May 7 and the facility entered commercial service May 21.

The plant will employ 22 permanent employees.

The Towantic project is the second major facility to be completed by Gemma for CPV — the first was an 800 MW facility in Palm Springs, California, in 2013. The Towantic project is part of 3,000 MW under construction by GPS in five states.

Gemma also reached substantial completion of the 475 MW NTE Middletown Energy Center in Middletown, Ohio. The plant was dispatched to the grid on May 21.

The project features a Mitsubishi Hitachi Power Systems Americas M501GAC combustion turbine generator, a Vogt Power International supplementary-fired heat recovery steam generator and a Toshiba America Energy Systems steam turbine generator.

The Ohio project is the sister project to the Kings Mountain Energy Center, also a 475 MW facility, located in Kings Mountain, North Carolina. It is scheduled to be completed later this year.

The Middletown Energy Center will employ approximately 25 permanent workers.
