Gemma has received interim notice to proceed (INTP) from NTE Ohio to commence EPC activities at the Middletown natural gas-fired power plant Ohio.

The facility will comprise an advanced Mitsubishi Hitachi Power Systems Americas (MHPSA) M501GAC combustion turbine generator, a Vogt Power International supplementary-fired heat recovery steam generator and a Toshiba America Energy Systems-built steam turbine generator.

The $300m Middletown energy center is expected to create 300 jobs during construction phase.

Under the contract with NTE Carolinas, Gemma Power will build the Kings Mountain natural gas electric generating facility in North Carolina.

The project will feature Mitsubishi’s GAC turbine technology in a combined-cycle configuration to recover exhaust heat from the gas turbine to produce steam.

The steam is then passed through a steam turbine, which uses the initial fuel to generate additional energy.

The two contracts are valued at $550m and the projects are scheduled to be completed in spring of 2018.

Gemma Power Systems has so far handled 11,000MW power projects, including combined cycle and simple cycle gas turbine generating plants, biomass, solar facilities, wind farms, biofuel plants and environmental facilities.
