NYISO Releases Power Trends 2025

RENSSELAER, NY (06/02/2025) (readMedia)-- The New York Independent System Operator (NYISO) today released Power Trends 2025, the company's annual state of the grid and markets report. Power Trends 2025 details how reliability margins continue to decline as fossil-based generation retires and new supply resources are not keeping pace with expected demand growth. Further, the report examines the impact on the electric system from an increase in large loads, such as semiconductor manufacturing, generative AI and data center projects.

"The grid is undergoing rapid and instrumental change," said Rich Dewey, President and CEO of the New York Independent System Operator. "We continue to observe declining reliability margins while forecasting a dramatic increase in load. It's imperative during this period of transition that we maintain adequate supply to meet growing consumer demand for electricity."

Power Trends 2025 also warns about the reliance on fossil-fuel generators that are fifty years of age or older, while highlighting the strength of competitive markets to attract the investment necessary to support the continued reliability of the grid.

"We recently streamlined the interconnection process for new generation and launched new market products intended to bring more power onto the grid at the most efficient cost." said Emilie Nelson, Executive Vice President and COO of the New York Independent System Operator. "Assessing short-term and long-term reliability risks, we will continue to collaborate with market participants, stakeholders and policymakers to develop sound solutions for the challenges ahead."

Key messages in Power Trends 2025 include:

• Generator deactivations are outpacing new supply additions. Electrification programs and new large-load customers associated with economic development initiatives are pushing projected demand higher. Together, these forces are also narrowing reliability margins across New York and increasing the risk of future reliability needs.

• As public policy goals seek to decarbonize the grid, fossil-fired generation will be needed for reliable power system operations until the capabilities it offers can be supplied by other resources. Energy efficiency and demand-side management (DSM) will continue to play a key role in reducing energy consumption, lowering costs, and mitigating environmental impacts.

• Repowering aging power plants can lower emissions, meet rising consumer demand, and provide reliability benefits to the grid that are needed to integrate additional clean energy resources.

• New York is projected to become a winter-peaking electric system by the 2040s, driven primarily by electrification of space heating and transportation. On the coldest days, the availability of natural gas for power generation can be limited, and interruptions to natural gas supply will introduce further challenges for reliable electric grid operations.

• New supply, load, and transmission projects are seeking to interconnect to the grid at record levels. NYISO's interconnection processes continue to evolve to balance developer flexibility with the need to manage the process to more stringent timeframes.

• Competitive wholesale electricity markets administered by the NYISO support reliability while minimizing costs to consumers.
