Who is proposing to build the Guernsey Power Station?

Guernsey Power Station (“GPS”) is a natural-gas fired power project is being developed by Caithness Energy and Apex Power Group.

Where will the Guernsey Power Station be built?

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

What benefits will the project provide to the local economy?

Tax revenues: Over its lifetime, the GPS 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 more than 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 benefits 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Air: Modern power plants are cleaner and more efficient than out-of-date facilities.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: 1,875 MW – produces electricity equivalent to the power needs of approximately one million homes

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

Fuel: Natural Gas

GPS 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 the 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 water conservation strategies, protecting the environment.

When is construction expected to begin?

Construction of GPS began in Q3 2019.

When is the plant expected to come on line?

GPS is anticipated to be online in the third quarter of 2022.

What is the source of the natural gas?

The Rockies Express (REX) Pipeline is located on-site and will transport natural gas to the project.  The REX–East starts in Clarington, Monroe County, Ohio and runs through Ohio, Indiana and Illinois to Missouri.  Large quantities of natural gas from the Utica and Marcellus shale in eastern Ohio and western Pennsylvania are injected into the pipeline at the Clarington Hub, upstream of the GPS.

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 required approvals from a variety of agencies before the construction process began, and remain in effect 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.
