Reliability Needs Assessment (RNA)
NYISO said it is no longer concerned about a violation of reliability criteria in New York City in 2033 and has canceled its search for a solution.
NYISO’s early 2025 will likely be dominated by the Reliability Needs Assessment process again, but the year will also bring other issues.
NYISO published the final, approved version of the 2024 Reliability Needs Assessment, which identifies a reliability need in New York City beginning in 2033.
The NYISO Board of Directors announced that it approved the ISO’s 2025 budget and incentive goals, along with the 2025-2029 Demand Curve Reset and the 2024 Reliability Needs Assessment.
The NYISO Management Committee passed the draft Reliability Needs Assessment and recommended that the Board of Directors approve it at its next meeting.
NYISO's transmission planning requirements result in a need for more capacity than is required in the ISO’s market rules, according to Potomac Economics, the Market Monitoring Unit.
In response to stakeholder criticism, NYISO updated its draft Reliability Needs Assessment to include an executive summary and appendices, and extended the comment period on the report.
NYISO released the first draft of its 2024 Reliability Needs Assessment showing a capacity deficiency in New York City beginning in 2033 and proposing to declare a reliability need for its zone.
NYISO made significant updates to its assumptions as part of its final Reliability Needs Assessment, which now shows no concern of a capacity deficiency and a loss-of-load expectation of less than 0.1 in 2034.
NYISO's update to its draft Reliability Needs Assessment still shows an expected capacity shortfall by 2034, though it is slightly less than what was initially presented in July.
