# Richard M. Flynn Power Plant NYISO power_plant · https://askthegrid.com/nyiso/assets/plant/richard-m-flynn-power-plant Richard M. Flynn Power Plant is a New York Power Authority-owned and operated natural-gas-fired combined-cycle power plant located at 607 Union Avenue in Holtsville, Brookhaven, Suffolk County, New York. It consists of one Siemens/KWU V84.2 dual-fired combustion turbine, a Nooter Eriksen two-pressure heat-recovery steam generator, and a condensing steam turbine generator, with fuel oil available as backup fuel. The plant was selected through a competitive bidding process by Long Island Lighting Company in 1990 and was the first power facility completed under New York's competitive-bidding system for new electric generating capacity. All electrical output was historically sold to LILCO under an exclusive power purchase agreement that expired in 2014; subsequent power output has been sold on a merchant basis in wholesale markets. Long Island Power Authority approved a 62-month capacity purchase agreement with NYPA effective November 2021 through December 2026 following major generator repairs in 2021. ## Key facts - Technology: Natural Gas Fired Combined Cycle - Power capacity: 170 MW ## Grid and market context - ISO/RTO: NYISO - Balancing authority: NYISO ## Source-backed facts - Technical.commercial operation date: May 1994 — nypa.gov · confidence: review_required - Technical.power mw: 170 MW — nypa.gov · confidence: review_required - Technical.energy mwh: 564000 MWh — nypa.gov · confidence: review_required - Identity.canonical name: Richard M.

LIPA reimburses NYPA for repair costs (lump sum payment) and purchases plant capacity at fixed price with availability guaranty. Total cost approximately $67 million. Term commences November 1, 2021 and ends December 31, 2026. LIPA has right to terminate prior to 2026 in event of significant plant failure.

The 170.0 MW figure is used as the official current capacity. A 2024 NYPA feasibility report modeled Flynn retirement in 2025 as a scenario assumption; however, the 2026 NYSDEC permit renewal explicitly describes continuation of an existing operational activity, and no retirement or deactivation notice has been published. The plant experienced a major generator failure on April 9, 2021, requiring significant repairs. NYPA indicated that merchant market revenues alone would not support these costs, leading to negotiation of a new capacity purchase agreement with LIPA approved August 2021. T. Main sharing overruns and underruns 50/50 with NYPA. No final actual construction cost is identified in the available evidence. The Siemens V84.2 gas turbine achieved 100,000 operating hours by January 6, 2005, with approximately 95 percent availability over its first decade. Only 73 units of this model exist worldwide. No acquisition price, sale consideration, portfolio transaction value, or ownership transfer before NYPA has been identified in the available evidence. - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] --- Canonical page: https://askthegrid.com/nyiso/assets/plant/richard-m-flynn-power-plant Source: Ask the Grid — https://askthegrid.com/
