How Reliability Needs are Identified on New York’s Grid
For some time now, the NYISO has been reporting on declining reliability margins on New York’s grid, noting that New York City, in particular, is at increased risk of outages as soon as 2025. On July 14, 2023, we published the findings from our second quarter 2023 Short-Term Assessment of Reliability (STAR) report. We found that through updates to our analysis margins in New York City disappear altogether in summer 2025.
