Installed Capacity Working Group
The final meeting of the Installed Capacity Working Group for the year, held Dec. 16, focused on proposed manual changes for several projects.
These include the alternative ICAP market parameters and the Control Area System Resource capacity market participation projects, which are to facilitate the integration of the Champlain Hudson Power Express transmission line. The parameters are to accommodate the line if it is late in beginning operation, as it will have a major impact on market prices and reliability. The CASR revisions would patch a few linguistic holes regarding how the manual addresses equipment failures.
NYISO will seek approval of the changes from the Business Issues Committee at its next meeting in January. Both projects have related tariff revisions pending before FERC.
The ISO also presented its Market Vision plan to stakeholders, emphasizing familiar themes of a changing grid, decreasing reliability margins, and the role of capacity and energy markets in meeting the energy and reliability needs of New York. The plan is a high-level overview of the timeline of major projects the ISO is undertaking, including the capacity market structure review, CHPE integration and handling the grid’s transition to winter peaking, among many other projects.
NYISO also presented improvements it is working to develop for the Thunderstorm Alert Settlement system because of issues that arose in July. Currently TSA settlements are reviewed manually, which can be time consuming.
Finally, the ISO presented a brief update confirming that it would continue the Storage as Transmission project into 2026.
Management Committee
The Management Committee on Dec. 17 approved two motions recommending the Board of Directors approve and file the tariff revisions for the Improved Duct-Firing Modeling project and the Hydro Quebec-NYISO interconnection agreement.
The committee also heard brief presentations of the accomplishments of NYISO under the 2025 Strategic Plan, and a repeat of the November Operations Report.
Transmission Planning Advisory Subcommittee
The Transmission Planning Advisory Subcommittee on Dec. 18 received a project update on the model development for the 2025-2044 System and Resource Outlook study. The study has nailed down a model for the base case and inputs for several other cases. Cost modeling will be finalized for all cases in the coming weeks.
TPAS also received an extremely short update on NYISO’s compliance with FERC Order 1920. Stakeholders were informed of the timeline of tariff revision development with a tentative filing date of April 30, 2026. (See NYISO Presents Preliminary FERC Order 1920 Plan to Stakeholders.)
Load Forecasting Task Force
The Load Forecasting Task Force heard a presentation Dec. 19 on the 2026 peak load forecast.
NYISO forecasts a peak load of 31,578.6 MW, roughly half of which (15,312 MW) is located in the New York City suburbs, Long Island and the city itself.
