Who is proposing to build the Guernsey Power Station?

An Ohio natural-gas fired power project is being developed by Apex Power Group.  Based in Indiana, Apex is a privately held power generation development company committed to providing efficient, reliable, and environmentally friendly energy.

For this project, Apex has partnered with Caithness Energy, L.L.C.

Caithness is an independent power producer engaged in the development of power plants from renewable energy and natural gas in the United States.  Caithness has successfully developed, operated and owned interests in over 42 power projects utilizing wind, geothermal, solar and clean natural gas.


Where will the Guernsey Power Station be built?

The plant will be located in the heart of Ohio’s shale development activity – Valley Township in Guernsey County in Southeast Ohio.


What benefits will the project provide to the local economy?

Tax revenues: Over its lifetime, the Guernsey Power Station will contribute substantial dollars in local taxes to the local community and the Rolling Hills Local School District.

Local services: The Village of Byesville will supply the plant with water and receive wastewater from the plant for treatment.  We anticipate partnering with local vendors to meet specific facility needs such as natural gas supply; routine services; and construction, maintenance and safety equipment. 

Local jobs: Plant construction will take approximately 30 months. The project will generate up to 500 construction jobs during peak construction phases.  Once the plant is online, it will employ approximately 25 long-term professional workers.


What are the environmental effects of such a plant?

Air: Modern power plants are cleaner and more efficient than out-of-date facilities. Modern plants burn one-third less fuel per unit of electricity generated than older plants. In addition, the advanced gas turbine technology available today is cleaner, reducing emissions of key air quality substances 90 percent or more per unit of electricity generated. As more modern power plants come online, the region will experience significant air quality benefits.

Water consumption: The cooling system for the steam turbine will be a closed cycle air-cooled condenser rather than a traditional water-cooled condenser. While more expensive, air-cooled condensers reduce water consumption by as much as 95 percent, minimizing the need for additional water treatment chemicals and significantly reducing wastewater generation.


What type of power plant will Apex and Caithness build?

Size: 1,650 MW – enough to power nearly 1.5 million homes

Generating technology: (3) 1×1 Combined-cycle units

Fuel: Natural Gas

Guernsey Power Station will be a state-of-the-art electric generating facility using the latest combined-cycle technology.  Combined-cycle natural gas plants result in the most efficient use of energy.  Using advanced technology, excess heat generated by the gas turbines power its steam turbines, thus producing more electricity with less fuel. The plant will be built to the highest possible standards using the latest emissions-control and noise-reducing technologies, while ensuring public safety and protecting the environment. 


When is construction expected to begin?

Construction of Guernsey Power Station is anticipated to begin in the first quarter of 2018.


When is the plant expected to come on line?

Guernsey Power Station is anticipated to be online in the third quarter of 2020.


What is the source of the natural gas?

The Rockies Express (REX) Pipeline is located on-site and will likely be the primary source natural gas.  The REX–East starts in Clarington, Monroe County, Ohio and runs through Ohio, Indiana and Illinois to Missouri.  The natural gas from the Utica and Marcellus shale in eastern Ohio and western Pennsylvania, which goes into the pipeline at the Clarington Hub, is a primary consideration to fuel the Guernsey Power Station.


What approvals are required for the project?

GPS is committed to protecting public health and the environment and will meet all state and federal laws and regulations concerning the building and operation of the plant. Doing so requires approvals from a variety of agencies before we begin construction, during the construction process, and indefinitely once the plant is in operation. These agencies include the Ohio Power Siting Board, the Ohio EPA, and our Regional Transmission Organization PJM Interconnection.
