As the transition to renewable energy accelerates in New York, we must monitor several factors to understand the impacts of this monumental change on electric system reliability. One of the biggest items to watch is progress with the Champlain Hudson Power Express (CHPE) transmission facility, and the impact the project could have on declining reliability margins in New York City.

The Reliability Needs Assessment (RNA) forecasts system conditions over the next ten years to determine whether the grid will have sufficient generating capacity and transmission capability to meet expected demand. If it does not, a reliability need is declared and the NYISO takes action to resolve it. The identification of reliability needs through this assessment is guided by mandatory reliability rules set by independent reliability organizations or accepted by regulators, including the North American Electric Reliability Corporation, the Northeast Power Coordinating Council, the New York State Reliability Council, and the Federal Energy Regulatory Commission.

This two-page datasheet provides the key takeaways from the 2022 Reliability Needs Assessment (RNA).
