The conversation during a five-hour meeting on changes to NYISO’s transmission planning processes became heated at times, as stakeholders challenged ISO officials on exactly how they will develop the possible scenarios they propose to determine reliability needs.

NYISO is proposing to use a set of multiple scenarios rather than relying on a single base case in its Reliability Planning Process to avoid study-by-study fluctuations in determining reliability needs.

NYISO began what is expected to be a yearlong effort of revising its Reliability Planning Process at a Transmission Planning Advisory Subcommittee meeting.

New York generators had to rely on oil as gas was scarce throughout the Eastern Interconnection during the Jan. 25-27 winter storm, NYISO said in a preliminary analysis.

NYISO staff presented more of their initial ideas for improving the Demand Curve Reset process, centered on alternative shapes, slopes and points of the curve.

NYISO kicked off the demand curve reset reform process with a discussion of how to improve the overall process and what could be done to strengthen the definition of the proxy unit.

The NYISO Transmission Planning Advisory Subcommittee discussed stakeholder comments on possible improvements to the cluster study process and the system deliverability test process.

If the Champlain Hudson Power Express comes in as expected, it will have an impact on both LCR and CAFs downstate.

NYISO's Installed Capacity Working Group's final meeting of 2025 focused on proposed manual changes for several projects.

The NYISO Market Monitoring Unit told the Installed Capacity Working Group that more data is necessary to verify the need for out-of-market actions on the part of transmission owners for reliability.
