NYISO Warns of Power Shortfalls in NYC and Long Island Starting Summer 2026

Delays to key projects leave the region dependent on interim fixes.

Overview

  • NYISO’s five-year assessment projects New York City could be 410–650 MW short during peak hours in 2026, rising to about 1,130 MW by 2030.
  • Long Island is forecast to face deficits of 39–116 MW beginning in 2027, reaching roughly 175 MW by 2030.
  • Reliability margins improve if the Champlain Hudson Power Express enters service in 2026 and later additions like Empire Wind and Propel NY arrive, though Empire Wind now faces a turbine-installation vessel contract issue after an earlier federal pause.
  • To cover near-term gaps, NYISO ordered the Far Rockaway turbines and the Pinelawn unit to provide interim service under regulated rates starting December 25, 2025.
  • The draft 10-year plan cites aging plants, rising large-load demand and difficult project development, and says several thousand megawatts of new dispatchable capacity may be needed, with worst-case shortages up to about 10,000 MW by 2034.
