NYISO Q2 STAR Report Shows Future Reliability Margin Breach

Albany, NY – The New York Independent System Operator (NYISO) today released its Q2 Short-Term Assessment of Reliability Report (STAR), which is a quarterly assessment of the reliability of the bulk electric system. This has become increasingly important with the electric grid’s transition as New York strives to achieve its climate goals. These assessments help to identify reliability needs that may arise within a five-year window.

This report confirms the anticipated reliability needs shown by the Q1 report, issued in April. The Q2 report studied the period of April 15, 2023, through April 15, 2028, and found that reliability margins could become deficient in New York City as soon as 2025. Reliability margins are expected to continue narrowing due to the planned retirement of certain generators in compliance with the New York State Department of Environmental Conservation’s “Peaker Rule.”

IPPNY President and CEO Gavin J. Donohue said: “The pace of play is not keeping up with pace of promises, and this report makes that clear. There have been repeated cautions from the NYISO regarding grid reliability, and this report highlights the reality that generator retirement cannot outpace the addition of new generation with the attributes needed by the NYISO to maintain reliability. This report should draw attention from state officials in shaping realistic public policies. I encourage the NYISO to identify solutions that are market-based so we can set ourselves on the pathway to a cleaner energy future, while maintaining the reliability of our grid at affordable rates.”

The Independent Power Producers of New York, Inc. (IPPNY) is the premier trade association dedicated to representing the largest fleet of clean energy generation in New York and its members are key proponents towards helping the state transition to a clean energy future. IPPNY supports the clean energy transition, as well as the development and implementation of an economywide Cap-and-Invest program.  


IPPNY, established in 1986, is a premier trade association dedicated to the representation of the State’s electric generation fleet, which powers New York’s economy. IPPNY Members produce clean electricity generation in this state; our Members have been successfully awarded more than half of the renewable energy credit contract awards from the New York State Energy Research and Development Authority, are leading proponents of meeting the State’s energy goals, while maintaining reliability, and are operating the facilities and making investments in additional ones to achieve the Climate Leadership and Community Protection Act’s targets. IPPNY Members also produce more than 75 percent of the State’s power from a multitude of fuel sources, such as: wind, solar, hydro, energy storage, natural gas, low sulfur oil, waste-to-energy, biomass, and nuclear. In combination, these resources maintain electric system reliability and “keep the lights on” for more than 19 million New Yorkers every day. Additionally, IPPNY’s Members have invested more than $10 billion in capital improvements at their facilities, employ over 10,000 people across the State, and pay approximately $1.7 billion in local property taxes annually. IPPNY does not represent investor-owned utilities or power authorities.
