Caithness LI Energy Center Stands Ready to Keep the Power Flowing During Summer Peak Demand

 Record of reliability, cost efficiency saved Long Island’s electric ratepayers $108 million in fuel costs over the last three years 

YAPHANK, NY  June 19, 2014 During the sweltering days of summer, the demand for power on Long Island reaches its peak as Long Islanders rely on ever more air conditioning and any other means they can to stay cool. With some observers predicting a hotter than normal summer, Caithness Long Island, LLC confirmed today that its Caithness Long Island Energy Center remains ready and available to help meet the increased demand for electricity on Long Island during the peak summer period. The New York Independent System Operator (NYISO) reported in its 2014 Power Trends report that New York State recorded an all-time record peak demand in July 2013 and that the peak demand is expected to continue to rise at about 2% per year.
The Caithness Long Island Energy Center, which began commercial operation in August 2009, has a proven record of highly reliable operations, having exceeded 99% availability to the Long Island Power Authority (LIPA) during 2012 and 2013. The 350-megawatt (MW) gas-fired, combined cycle power plant is the cleanest, most efficient and most water conserving power plant on Long Island and over the last two years has generated more than 20% of the power produced on Long Island and approximately 10% of the total electricity consumed by LIPA’s customers.
Because of the Caithness Long Island Energy Center’s high efficiency and reliability, it is most often called upon to produce electricity before the older, inefficient, more polluting power generating resources on Long Island. Thanks to Caithness’s economic efficiency, Long Island’s electric ratepayers have saved $108 million in fuel costs over the past three years. This state-of-the-art, combined cycle power plant produces electricity 33% more efficiently than the decades-old steam-turbines based plants that Long Island otherwise relies on.
Combined cycle power plants, like the Caithness Long Island Energy Center, utilize both natural gas and steam turbines. The gas turbine generates electricity, while the steam turbine produces additional electricity using waste heat from the gas turbine. The process is highly efficient because the exhaust heat produced by the gas turbine, that would otherwise be lost through the exhaust stack, is re-used to generate additional electricity, producing 50% percent more electricity using the same amount of fuel.
