Hell Gate is a 94 MW natural-gas-fired power station located at 910 East 134th Street, Bronx, New York, owned and operated by the New York Power Authority. emergency generation program. As of March 2026, NYISO's C24 cluster records identify a proposed 90 MW energy-storage repowering project (C24-331) that would retire both existing Hell Gate gas turbines and redevelop the site with battery storage by December 2028.

## Timeline

- 2001-07 — Hell Gate GT#1 and GT#2 commercial operation
  Hell Gate units 1 and 2 entered commercial operation as part of NYPA's PowerNow! program. EPA places the 11-unit portfolio's commercial operation between July 25 and August 17, 2001; the plant record identifies Hell Gate's initial operation as July 2001.

## Data quality

- The $640 million construction cost reported by the New York State Comptroller applies to the entire 11-unit PowerNow! portfolio (Harlem River Yard, Hell Gate, 23rd and 3rd, Vernon Boulevard, Pouch terminal, North 1st, and Brentwood), not to Hell Gate alone. No Hell Gate-specific construction-cost allocation was found in the available evidence. EPA places the commercial operation of the 11 PowerNow! turbines, including Hell Gate, within the window of July 25–August 17, 2001. Plant-level EIA-derived data identifies Hell Gate's initial operation as July 2001, but does not specify a day or precise date. The similarly named former Consolidated Edison Hell Gate Station is a different historic asset and is excluded from this record. As of the latest operating evidence (December 2025 NYISO existing-generating-facilities list), both Hell Gate units remain listed as existing facilities. The Comptroller's 2004 statement that at least one of the 11 PowerNow! units 'may be shut down' at end of 2004 is a historical observation and does not confirm that either Hell Gate unit was retired; Hell Gate remains in operation through 2026 per NYISO records. The plant record identifies energy storage as absent; Hell Gate is a natural-gas combustion-turbine generation facility, not a battery or hybrid resource. The proposed C24-331 repowering is a future project, not an existing battery-storage facility.
