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 Kearny Generating Station consists of 10 simple cycle units on the banks of the Hackensack River in South Kearny, New Jersey.  It is a top performing diverse station, consisting of dual fuel and fast start optionality, has black start capability, and provides synchronous condensing for grid stability. 

The Keys Energy Center is a best-in-class combined cycle facility yielding the most efficient operation in the Maryland region of PJM.  The facility is located in Brandywine, Maryland and features the most advanced Siemens F-Class combustion turbine (CT) generators.  The station was designed to operate in daily cycling mode and to run continuously as base load.  Keys’ unique design allows for full bypass operation if required, operating CTs in simple-cycle and fast unit startups with one hour to dispatch.

The Linden facility is a best-in-class combined cycle asset, providing capacity to the PJM and NYISO grids.  With dual combined cycle configurations, Linden provides a wide range of load flexibility between 150MW and 1,300MW.  The simple cycle combustion turbines provide black start capability for grid resiliency.  Fuel oil is used as a backup to enhance reliability and fuel optionality.

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.

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.

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.

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.

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.
