Eversource working to interconnect 63-MW Beacon Falls fuel cell project

Eversource Energy Service Co., on behalf of affiliate Connecticut Light and Power (CL&P), on Sept. 29 filed with FERC an executed Agreement for Engineering, Design and Procurement Services with Beacon Falls Energy Park LLC, which is developing a fuel cell project in Connecticut.

Beacon Falls is proposing to construct an approximately 63.3-MW fuel cell project located on approximately eight acres of a 25-acre former sand and gravel mine along Lopus Road in Beacon Falls, Connecticut, and to interconnect the facility to CL&P’s existing 115-kV transmission system. CL&P and Beacon Falls are in the process of completing a Standard Large Generator Interconnection Agreement (LGIA).

ISO New England has completed studies on its regional transmission system regarding the facility’s impact, and such studies identified the need for construction of Interconnection Facilities by both CL&P and Beacon Falls. The purpose of this agreement is to set forth the terms and conditions under which CL&P would undertake to provide design and/or engineering necessary to complete a plus or minus 25% cost estimate to modify CL&P’s Beacon Falls substation and construct the 115 kV electrical interconnection to the facility’s switchyard.

The Connecticut Siting Council sent a Jan. 11 letter to Beacon Falls Energy Park LLC saying that the council on Jan. 7 approved this 63.3-MW fuel cell project. In August 2015, the company requested that the council issue a declaratory ruling for the location, construction, operation and maintenance of a 63.3-MW fuel cell project and associated ground equipment, an ancillary building and a 115-kV interconnection located on about eight acres of a former sand and gravel mine along Lopus Road in Beacon Falls, Connecticut. Natural gas as feedstock for the fuel cells would be provided by a new 8-inch-diameter gas line.

Beacon Falls Energy Park LLC is a wholly owned subsidiary of O&G Industries Inc. The project consists of:

  • Five FCE HEFC molten carbonate fuel cells, each rated at approximately 3.7 MW
  • Sixteen FCE DFC3000 molten carbonate fuel cells, each rated at approximately 2.8 MW
  • Switchyard facilities
  • A metering facility

O&G Industries, based in Torrington, Connecticut, will be the Engineer Procure Construct (EPC) contractor for the project. O&G is a large and experienced EPC contractor and has built and completed energy generating facilities. O&G owns the property upon which the project will be located.

FuelCell Energy Inc., based in Connecticut, will manufacture, supply, construct and operate the fuel cells.
