Pinelawn Power LLC is a 82 MW dual-fuel natural-gas/oil combined-cycle generating facility located at 380 Patton Avenue, West Babylon, Suffolk County, New York. The plant entered service in 2005 with simple-cycle operation beginning in July 2005 and full combined-cycle operation in October 2005. The facility comprises a GE LM6000 gas turbine (50 MW), an Innovative Steam Technologies once-through steam generator with natural-gas duct burners, and a Siemens steam turbine (32 MW) in a 1×1 combined-cycle configuration. The plant originally supplied power to the Long Island Power Authority under a 20-year power-purchase agreement. Hull Street Energy acquired the asset from J-Power USA in 2024, and the facility is now part of the Milepost Power fleet. As of June 2025, a NYISO-completed deactivation notice identified a proposed retirement with an earliest possible retirement date of May 15, 2026.

## Data quality

- Capacity reporting varies by source and definition. NYISO nameplate: 82.0 MW. Former owner project page: 79.9 MW. EIA unit sum: 50 MW + 32 MW = 82 MW. Construction report: ~80 MW. Current Milepost portfolio: 75 MW. The selected 82.0 MW nameplate reflects the most recent NYISO regulatory designation. Operating status after May 15, 2026 ISP termination date is not confirmed in retrieved sources. The asset was authorized to deactivate but the retrieved evidence does not independently confirm physical retirement. Simple-cycle operation began July 2005; full combined-cycle operation began October 2005. The facility operated in simple-cycle mode for approximately 3 months while construction continued. The 20-year PPA with LIPA would expire in 2025 if dated from 2005 commercial operation, but the retrieved evidence does not explicitly confirm the PPA end date or whether LIPA continued purchasing after 2025. Original Pinelawn Power LLC joint-venture participants (DiFazio Electric Incorporated and Harbert Power LLC) are not explicitly identified in current ownership records; their roles ended in the initial development phase. The $35 million figure represents the original construction project cost, not the 2024 acquisition price, which was not disclosed in the available sources.
