In 1990, New York Power Authority (NYPA), was selected to provide 150 MW of electrical power to Long Island Lighting Company (LILCO), using a combined gas and steam turbine cycle. The gas turbine chosen was a Siemens V84.2 with a design ISO rating of 103 MW. NYPA, acting as an independent power producer, would build, operate and maintain the facility. The power plant would be dispatched by LILCO for a period of twenty years from the beginning of its commercial operation on May 1, 1994. The construction was completed in 20 months and the unit started commercial operation on schedule. The formal performance acceptance tests, conducted in June 1994, indicated a better net output power and a lower net heart rate than the guaranteed figures for operation with natural gas and light distillate as the backup fuel. Stack emissions compliance tests conducted in October 1995, successfully demonstrated NOx emissions of 9 ppmvd (15% O{sub 2}) for dry combustion of natural gas. In its first year of operation the plant achieved a rolling average equivalent availability rate (EAF) of 94.6%; NYPA`s target is 90.42% for a twenty year contract term. This article will review Siemens NOx abatement technology to obtain single digit emissions and describe the operational experience with the dry low NOx system at the Richard M. Flynn Power Plant.
