Astoria Generating Station
The Astoria Generating Station is a 959 MW natural gas fired plant located in Astoria, in the Queens borough of New York City, bounded by the East River and Luyster Creek. It consists of four generating units (Units 2, 3, 5 and GT-1) with an aggregate average capacity rating of 957 MW. Units 3 and 5 have the ability to operate on ULSD No. 2 fuel oil as a backup during periods gas system constraints. Astoria’s dispatch level is intermediate.
The plant is part of a larger complex that is comprised of approximately 300 acres, most of which is used for various utility purposes including power generation, indoor storage, oil storage, liquefied natural gas storage, vehicle storage and servicing and office space.
The Narrows Generating Station is a 322 MW floating power station located in Brooklyn along the east side of Upper New York Bay. The facility consists of 16 simple-cycle combustion turbine units on two floating power barges. All of the units at Narrows have dual-fuel capability. The units at Narrows also provide critical system peaking capacity and can be started in fifteen minutes or provide Black Start capability for system restoration. Throughout the year the units serve as peaking resources.
The Gowanus Generating Station is a 640 MW floating power station located on Gowanus Bay in Brooklyn along the east side of the Upper New York Bay. The facility consists of 32 simple cycle combustion turbine units situated equally across four generating barges. The facility is one of the largest floating generating stations in the world. The site also includes approximately 25 acres of piers and submerged land.
The Gowanus facility can start with as little as fifteen minutes notice. The units are flexible from an operating perspective and are available year-round to offer system- peaking capacity. With 16 of 32 units equipped for dual-fuel firing, the site has additional optionality regarding fuel selection. In addition, the facility has black-start capability and was the first generating station to resume operations following the Black Out in August 2003.
The Montville Generating Station is an approximately 500 MW peaking plant providing enough power to support over 400,000 homes during peak electric demand periods. The plant’s four units are either dual-fuel (gas or oil), oil-fueled or diesel-fueled generators. The 49-acre facility along the Thames River supplies power to ISO-NE. Generation Bridge acquired the station from NRG in 2021.
The Middletown Generating Station, situated along the Connecticut River in the Maromas section of Middletown, CT, is an approximately 762 MW plant consisting of three steam units and one combustion turbine capable of powering 600,000 homes. Middletown supplies power to ISONE. Generation Bridge acquired the station from NRG in 2021.
The Devon Generating Station, located on the Housatonic River near the Long Island Sound, consists of five fast-start peaking units with a total approximate capacity of 175 MW. The facility includes four 50-MW dual-fueled combustion turbines, enough to power more than 160,000 homes. Generation Bridge acquired the facility from NRG in 2021.
Generation Bridge’s Connecticut Jets consists of four remote jet engine stations located in Cos Cob, Branford, Torrington (Franklin Drive) and Torrington Terminal. The stations comprise 167 MW of capacity in aggregate and are capable of rapidly dispatching to meet demand. Generation Bridge acquired the Jets in 2021 from NRG.
The Arthur Kill Generating Station is an 866 MW natural gas fired plant consisting of two steam turbines and one gas turbine located in the Staten Island borough of New York City. Steam units 2 and 3 were built in 1959 and 1969, respectively. Generation Bridge acquired the station from NRG in 2021.
The Oswego Generating Station is located on 93 acres along the south shore of Lake Ontario and can generate enough electricity to support over 1.3 million homes. The 1,641 MW facility consists of two large steam generators that are primarily oil-fueled. Unit 5 was built in 1975 and unit 6 in 1979. Both are currently operating as peaking units and sell power to the NYISO. Generation Bridge acquired the station from NRG in 2021.
The Sunrise Generating Station is a 586 MW 2×1 natural gas-fired combined cycle plant located in Fellows, California. The plant consists of two GE Frame 7FA gas turbines and one Alstom steam turbine with Selective Catalytic Reduction technology. The plant commenced commercial operation in 2001/2003 and was purchased from NRG by Generation Bridge in 2021.
The Long Beach Generating Station, located in Los Angeles County, consists of four simple-cycle natural gas-fired turbines totaling 252 MW of installed capacity. The facility was repowered in 2007 by NRG before Generation Bridge acquired the asset in 2021.
Bridgeport Harbor Station 5 is an approximately 500 MW highly efficient combined cycle generating station that began commercial operations in Bridgeport, CT, in 2019. The station is dual-fuel capable, running primarily on natural gas with ultra-low sulfur distillate as a reliability back-up fuel, and is equipped with the latest state-of-the art emissions control technologies. Generation Bridge II acquired the station from PSEG in February 2022.
New Haven Harbor
New Haven Harbor consists of generation units 1-4 located in New Haven, CT. Unit 1 is an approximately 435 MW dual fuel capable steam turbine generating station which first began commercial operations in 1975. Units 2-4 are gas fired peaking turbines with an aggregate generating capacity of approximately 140 MW. Generation Bridge II acquired the facilities from PSEG in February 2022.
Bethlehem Energy Center
The Bethlehem Energy Center is an approximately 900 MW combined cycle generating station located in Bethlehem, New York, that entered service in 2005. The station is dual-fuel capable, running primarily on natural gas with ultra-low sulfur distillate as a reliability back-up fuel, and is equipped with emissions control technologies. Generation Bridge II acquired the facility from PSEG in February 2022.
