Powering Long Island
Past Powering Projects
This section describes some of the actions LIPA has taken to provide a reliable supply of electricity for its customers.
Caithness LI Energy Center (2009 PROJECT)
The Caithness Long Island Energy Center (CLIEC) is the most energy efficient and environmentally friendly power plant on Long Island. It produces up to 350 megawatts of electricity utilizing its combined cycle design. Learn more
Neptune Regional Transmission System (2008 PROJECT)
The Neptune Regional Transmission System is an electric transmission cable system that links Long Island to diverse, lower cost sources of energy supply in New Jersey, Pennsylvania and eleven other states in the mid-Atlantic and Ohio River Valley regions. It provides up to 660 megawatts of electricity to help meet Long Island's needs. Learn more
Southampton - Bridgehampton Transmission Line (2008 PROJECT)
The Long Island Power Authority Southampton to Bridgehampton Transmission Line Project is the construction of a 69 kilovolt (kV) transmission line between the Southampton and Bridgehampton Substations. Learn more
Northport to Norwalk Cable Replacement (2008 PROJECT)
LIPA and Connecticut Light & Power Company (CL&P) replaced the 300 megawatt electric transmission cable system that connects Long Island, New York with southwest Connecticut as part of a settlement agreement between the two states that allowed commercial operation of the Cross-Sound Cable between Shoreham, New York and New Haven, Connecticut.

Pinelawn Power Electric Generating Facility (2005 PROJECT)
The 79.9 megawatt Pinelawn Power electric generating facility in West Babylon was one of two state-of-the-art combined cycle power plants completed on Long Island in 2005. It is one of the most efficient power plants on Long Island. LIPA purchases the power generated by the facility under a 20-year Power Purchase Agreement. The facility is located in an industrial area adjacent to a municipal landfill and uses state-of-the-art pollution control equipment. It is fueled primarily with natural gas, with liquid fuel as backup. The facility’s equipment includes a General Electric LM 6000 combustion turbine generator, a once-through steam generator equipped with duct burners, a steam turbine generator, and a two-cell evaporative cooling tower.
Calpine Bethpage Energy Center 3 (2005 PROJECT)
The 79.9 megawatt Calpine Bethpage Energy Center 3 was one of two state-of-the-art combined cycle power plants completed on Long Island in 2005. It is one of the most efficient power plants on Long Island. LIPA purchases the power generated by the facility under a 20-year Power Purchase Agreement. The facility is located adjacent to existing Calpine power generation facilities and uses state-of-the-art pollution control equipment. It is fueled with natural gas. The facility’s equipment includes a GE LM 6000 combustion turbine generator, an IST once-through steam generator equipped with duct burners, a Siemens Westinghouse steam turbine generator, and a five-cell cooling tower.
Newbridge Road Connector Project (2004 PROJECT)
LIPA has built an underground electric transmission line to connect three substations that form part of the backbone of Long Island's transmission system. The Newbridge Road Connector has enhanced system reliability by reinforcing and increasing the capability of existing transmission capacity. Learn more
Cross-Sound Cable (2002 PROJECT)
The Cross-Sound Cable (CSC) is a 330 megawatt high voltage direct current (HVDC) electric transmission cable between Shoreham, New York and New Haven, Connecticut. It was completed in 2002 but did not begin commercial operation due to opposition from the State of Connecticut. Following the blackout of August 2003, the federal Department of Energy issued an emergency order that allowed the cable to operate until May of 2004. CSC finally began regular commercial operations in June of 2004 under a settlement negotiated between New York and Connecticut. CSC provides LIPA with access to lower cost sources of electricity in New England and has improved electric system reliability on both sides of the Long Island Sound. In conjunction with the Neptune cable between Sayreville, New Jersey and New Cassel, New York, the Cross-Sound Cable has opened up an electric transmission corridor from the Midwest to Long Island and on into New England and Canada.
Power Generation Projects 2002-2004
During the summer of 2001, LIPA determined that due to Long Island's rapidly growing demand for electricity, there was an urgent need to add at least 400 megawatts (MW) of new electric power generation capacity on Long Island. LIPA followed a rigorous environmental review and public outreach process which successfully added six new electric generating facilities around Long Island in 2002. LIPA increased competition in the power plant business on Long Island by selecting four different developers for the six projects. Calpine built a 44 MW facility in Bethpage; Florida Power & Light built a 53 MW facility in Far Rockaway; KeySpan built 79.9 MW facilities in Glenwood Landing and Port Jefferson; and Pennsylvania Power & Light built 79.9 MW facilities in Brentwood and Shoreham. Additional facilities were built in 2003-04 to meet continuing growth in summer peak demand for electricity on Long Island: the 54 MW Hawkeye Greenport Generating Facility; the 55 MW Jamaica Bay Energy Center built by Florida Power & Light in Far Rockaway; and twin 46 MW facilities built by Equus Power in the Village of Freeport.
