# Edgewood Energy LLC NYISO power_plant · https://askthegrid.com/nyiso/assets/plant/edgewood-energy-llc Edgewood Energy LLC is an 88 MW natural-gas-fired simple-cycle combustion-turbine power plant located in Brentwood, New York, within the Long Island submarket of NYISO. The facility comprises two GE LM6000 PC Sprint turbine generators, each rated 50 MW, and includes selective catalytic reduction (SCR) units, generator step-up transformers, gas-compression equipment, mechanical and electrical support buildings, water-injection systems, a sound wall, and an oil tank farm. Constructed between February and July 2002 by Phoenix Power Group under a fast-track schedule for Pennsylvania Power & Light, the plant has operated continuously since July 2002. Its output is sold to the Long Island Power Authority to meet peak-load demand and provide local grid reliability in western Suffolk County. The facility interconnects to LIPA's 69 kV grid at the Brentwood transmission node and is part of the NYISO balancing authority and Long Island submarket. As of January 2025, Edgewood is owned and operated by MPH Cross Island Power LLC, a special-purpose vehicle controlled by Hull Street Energy and operating within the Milepost Power generation portfolio. ## Key facts - Technology: Natural Gas Fired Combustion Turbine - Power capacity: 100 MW ## Grid and market context - ISO/RTO: NYISO - Balancing authority: NYISO ## Source-backed facts - Technical.commercial operation date: July 2002 — jpowerusa.com · confidence: review_required - Technical.power mw: 100 MW — climate.ny.gov · confidence: review_required - Technical.unit count: 2 — jpowerusa.com · confidence: review_required - Operations.resource type: Natural-gas-fired simple-cycle combustion turbine — lipower.org · confidence: review_required - Operations.grid role: Peak-load generation providing local reliability support in western Suffolk County on Long Island — lipower.org · confidence: review_required - Operations.balancing authority: New York Independent System Operator (NYISO) — jpowerusa.com · confidence: review_required - Operations.market resource ids: PTID 24216 (CT01) and PTID 24217 (CT02) — ethree.com · confidence: review_required ## Timeline - 2002-02 — Edgewood construction commenced Phoenix Power Group and partner construction company began construction of the Edgewood simple-cycle power plant on a fast-track design-build basis.

Phoenix Power Group lists 80 MW (project design), J-Power USA lists 88 MW (official project page), the New York PSC petition describes approximately 85 MW (summer rating), and state inventory plus unit-level records support 100 MW (two 50 MW units nameplate). All are valid under their respective rating methodologies. The J-Power figure (88 MW) is the plant owner's published capacity and is treated as the primary reference; the 100 MW nameplate is supported by independent government data. Capacity factor data: The New York State power-plant inventory reports 2018 and 2019 capacity factors (12.4% and 6.9%, respectively), indicating variable utilization as a peak-load asset. These do not conflict with the plant's peaking role. Project client identification: Phoenix Power Group identifies Pennsylvania Power & Light as the project client; LIPA records confirm PPL subsidiary ownership of the original facility until 2009 sale to J-Power USA. PPA expiration: The 2018 LIPA document describes a five-year extension of the power purchase agreement extending operation through 2023. Current status post-2023 is not explicitly documented in the provided sources but regulatory filings and transaction announcements describe the facility as operating in 2024–2025. The acquisition is fully documented in public sources. No material conflicts: The identity of Edgewood Energy LLC (EIA 55786) is unambiguous and consistently referenced across official sources including J-Power, NYISO, NYPSC, EIA, and EPA records. - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] --- Canonical page: https://askthegrid.com/nyiso/assets/plant/edgewood-energy-llc Source: Ask the Grid — https://askthegrid.com/
