Supplemental Analysis

In December 2025, NYSERDA published the 2025 New York State (NYS) State Energy Plan (SEP). During the process, stakeholders and board members identified additional topics to explore as continuation of the State Energy Plan Pathways Analysis.

Resource Cost and Fuel Price and High Large Load Growth Sensitivities

The memorandum [PDF] summarizes the findings from the Resource Cost and Fuel Price and High Large Load Growth sensitivities on impacts to the energy system through 2040.

 Two supplemental annexes offer detail on the modeling methodology, input data, data sources, scenario assumptions and results:

• Pathways Analysis Technical Supplement: Inputs and Assumptions – March 2026 [XLSX]
• Pathways Analysis Technical Supplement: Key Drivers and Outputs – April 2026 [XLSX]
