released its Short-Term Reliability Process Report on April 15, 2026, selecting solutions to address generator deactivation reliability needs in New York City, Long Island, and the Lower Hudson Valley through 2030.
New York City faces summer peak deficiencies of 410 to 650 MW this year, growing to over 1,100 MW by 2030. The Gowanus and Narrows barges have been extended through May 2029 — the maximum allowed under the NYS DEC Peaker Rule — but they are not enough on their own. Without Champlain Hudson Power Express in service this summer, NYC could still be short by up to 187 MW at peak, and operators would be left managing the gap with emergency procedures.
New York City faces summer peak deficiencies of 410 to 650 MW this year, growing to over 1,100 MW by 2030. The Gowanus and Narrows barge operations have been extended through May 2029 — the maximum allowed under the NYS DEC Peaker Rule — but they are not enough on their own. Without Champlain Hudson Power Express, the Gowanus-Greenwood 345/138 kV feeder, Empire Wind, and the Propel NY transmission project in service, NYC could still be short by up to 187 MW at peak under a barges-only scenario, and operators would be left managing the gap with emergency procedures.
Statewide, the system margin goes negative as early as summer 2027 under current demand forecasts. NYISO describes this as a leading indicator of the system's inability to securely serve demand under normal operations. Emergency procedure usage is projected to triple over the next decade without new dispatchable generation coming online.
The longer-term numbers are harder to ignore. About 3,000 MW of New York's fossil fleet is expected to be unavailable by 2034, with 60% of that risk sitting in New York City. No permanent solution proposed through the solicitation process was found viable for NYC beyond 2029.
The NYISO quarterly Short Term Assessment of Reliability (STAR) process will continue to track how planned projects are progressing.
