USA, New York: NYISO found a deficit of 446 MW in reliability margins for the New York City area beginning in summer 2025.
The New York Independent System Operator (NYISO) has released its Short-Term Assessment of Reliability (STAR) of the bulk electric system for the period April 15, 2023, through April 15, 2028, which found a deficit of 446 MW in reliability margins for the New York City area beginning in summer 2025 due to an increase in peak demand and the unavailability of certain generators. New York City’s reliability margin will improve with the completion of Champlain Hudson Power Express transmission line by spring 2026.
Increased electrification of the transportation and building sectors, continued economic growth, and the unavailability or retirement of select generators under the New York State Department of Environmental Conservation’s emissions limits, effective May 2023, are the main causes for the New York City’s reliability need in 2025.
“The reliability of the electric system is essential to the health and safety for all New Yorkers as well as the state’s economy,” said Zach Smith, NYISO’s Vice President of System and Resource Planning. “The NYISO will now work to identify solutions to the reliability need identified in New York City.”
The reliability need is based on a deficiency in transmission security. NYISO will initiate steps to bring reliability margins back to acceptable operating levels by working with the local utility and the marketplace to identify and evaluate possible solutions.
