The Guernsey Power Station (GPS) is a 1,875 megawatt, natural gas fired energy generation facility that will produce electricity equivalent to the power needs of approximately one million homes.

GPS will be located in southern Guernsey County in Southeastern Ohio, in the heart of the state’s Utica and Marcellus shale gas development area.

Using state-of-the-art combined cycle technology and a dry (air) cooling system, GPS will be a cost-efficient, fuel-efficient plant that protects air quality and conserves water. It will also boost the local economy through job creation and tax revenue for the local community and schools.

GPS has been jointly developed by Caithness Energy, L.L.C. and Apex Power Group, LLC.

Caithness Energy, L.L.C. is an independent power producer engaged in the development of power plants from renewable energy and natural gas in the United States.  Over the last 40 years, Caithness has successfully developed, operated and owned interests in more than 42 power projects across the United States using wind, geothermal, solar and natural gas.  Caithness recently partnered with Moxie Energy LLC to develop the Caithness Moxie Freedom Generating Station in Luzerne County, Pennsylvania, a 1,029 megawatt natural gas fired generating facility which reached commercial operations in 2018.

Apex is a privately held power generation development company committed to providing efficient, reliable, and environmentally friendly energy.  Apex recently developed two natural gas fired plants in California, the Panoche Energy Center and Pio Pico Energy Center.  In addition to GPS, Apex is developing Neches Station, a plant in Cherokee County, Texas.
