Gemma Power Systems said it received full notice to proceed on an engineering, procurement and construction services contract with Clean Energy Future-Trumbull, the developer of the Trumbull Energy Center, a $1.2 billion, 950 MW natural gas-fired power plant in Lordstown, Ohio. 

CEF-Trumbull is a consortium made up of Korea Southern Power Co. (KOSPO), Korea Overseas Infrastructure & Urban Development Corp. (KIND) and Siemens Energy.

The combined cycle power station will consist of two Siemens Energy SGT6-8000H gas fired, high efficiency, combustion turbines with two heat recovery steam generators and a single steam turbine. 

The project was first proposed in 2015 with a projected in-service date of 2020. The pandemic slowed progress as did details related to property acquisition, foreign ownership and water supply agreements. The plant now may enter service in 2026.

Gemma is an EPC services company that has been involved in 15 GW of installed capacity including combined cycle and simple cycle natural gas power generating plants, biomass-fired power plants, solar facilities, wind farms, biofuel plants and other environmental facilities. 

The facility will consist of two combined cycle combustion turbines (3,025 mmBtu/hr heat input turbine at ISO conditions and 237 mmBtu/hr heat input duct burner) with dry low NOx combustors, selective catalytic reduction, and catalytic oxidizer, a 37.8 mmBtu/hr natural gas fired auxiliary boiler with low-NOx burners and flue gas recirculation, a 1,140 kW (mechanical) emergency diesel-fired generator, a 300 hp emergency diesel-fired fire pump, and a 10-cell wet cooling tower equipped with a high efficiency drift eliminator.

The combined cycle combustion turbines will be equipped with dry low NOx combustors, selective catalytic reduction, and catalytic oxidation. The auxiliary boiler will be equipped with low-NOx burners and flue gas recirculation. The wet cooling tower will be equipped with a high efficiency drift eliminator.

Project finance was recently finalized, allowing the notice to proceed to occur. The project received a 100%, 15-year local tax abatement, but the company agreed to make payments in lieu of taxes to the Lordstown Local School District and to the village. The district and village will also evenly split income tax from the power plant.
