Fore River Energy Center

Located about 12 miles southeast of Boston, the Fore River Energy Center is a 731 megawatt, combined-cycle plant purchased by Calpine in November 2014. The plant consists of two combustion turbines, two heat recovery steam generators and one steam turbine. 

While Fore River primarily operates on clean-burning natural gas, it can also run on ultralow-sulfur diesel fuel oil, depending on market conditions. This flexible, dual-fuel capability is increasingly important to enhance power reliability in the region.

Highly efficient, combined-cycle facilities like Fore River consume 40 percent less fuel per megawatt-hour produced than older plants, making them cost-effective, low-carbon sources of electricity. Fore River is equipped with advanced emission control technologies including selective catalytic reduction systems, oxidation catalysts and dry, low-NOx combustors. In addition, its design minimizes wastewater discharge.

All of Fore River’s energy, capacity and ancillary services are sold into the competitive wholesale power markets administered by ISO-New England.
