# Jamaica Bay Peaking NYISO power_plant · https://askthegrid.com/nyiso/assets/plant/jamaica-bay-peaking Jamaica Bay Peaking is a 60.5 MW simple-cycle, dual-fuel (natural gas and petroleum liquids) combustion-turbine peaking plant located in Far Rockaway, Queens County, New York. It is interconnected to the 69 kV system in Long Island Power Authority's service territory at the Far Rockaway substation and participates in the New York Independent System Operator wholesale market. After the PPA expired, the facility operated on a merchant basis in the NYISO wholesale market. As of 2024–2025, emissions-control equipment underperformance resulted in deration to approximately 47 MW and prompted a planned retirement notice; however, the facility returned to market service in May 2026 under an interim service agreement with NYISO, reflecting its critical role in supporting Long Island bulk-power-system reliability. ## Key facts - Technology: Petroleum Liquids - Power capacity: 60.5 MW ## Grid and market context - ISO/RTO: NYISO - Balancing authority: NYISO ## Source-backed facts - Technical.commercial operation date: 2003-07-02 — documents.dps.ny.gov · confidence: review_required - Technical.power mw: 60.5 MW — mbrweb.ferc.gov · confidence: review_required - Technical.site acres: 2 acres — documents.dps.ny.gov · confidence: review_required - Technical.interconnection voltage kv: 69 kV — documents.dps.ny.gov · confidence: review_required - Identifiers.eia plant id: 56141 — mbrweb.ferc.gov · confidence: review_required - Identifiers.ferc tariff docket: ER03-623 — elibrary.ferc.gov · confidence: review_required ## Timeline - 2002-12-19 — CPCN Authorization The New York Public Service Commission granted Jamaica Bay Peaking Facility, LLC a Certificate of Public Convenience and Necessity to construct and operate a proposed 48 MW electric generating facility in Far Rockaway.

Capacity ratings vary by context: the original 2002 PSC order authorized 48 MW; later PSC records describe 54.5 MW summer rating; current FERC and NYISO registers show 60.5 MW. These differences reflect changes in rating methodology and operating experience rather than conflicting factual claims. The 60.5 MW is the current nameplate capacity. The facility is consistently described as dual-fuel (natural gas and petroleum liquids) and is capable of switching between fuels. The PSC order and DEC permit confirm dual-fuel operation, while the EIA petroleum-liquids classification is an artifact of fuel categorization and does not contradict gas capability. The purchase price was not disclosed publicly, and the PSC purchase-and-sale agreement was marked confidential. The facility did not retire on its October 31, 2025 identified retirement date. Instead, it continued operations under an NYISO Interim Service Provider agreement and returned to market service on May 1, 2026. This reflects the asset's critical role in Far Rockaway load-pocket reliability. The 2025 LIPA CPA is proposed but not yet executed. The estimated $91 million cost is LIPA's projected 10-year payment obligation, separate from the original project financing of approximately $50 million. Emissions-control equipment degradation and planned repairs are documented as of 2024–2025, but the record does not confirm completion of all repairs or equipment replacement by July 25, 2026. - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] --- Canonical page: https://askthegrid.com/nyiso/assets/plant/jamaica-bay-peaking Source: Ask the Grid — https://askthegrid.com/
