A 11402

Establishes a long-duration energy storage procurement target in New York state

2025 Regular Session

New York must contract at least 3,000 MW of long-duration energy storage by 2030 (1,500 MW inter-day and 1,500 MW multi-day) to support reliable, clean power.

Bill Summary · A 11402

Overview

A 11402 proposes establishing a long-duration energy storage (LDES) procurement target for New York state. The bill aims to ensure a defined level of LDES capacity to support affordability, reliability, decarbonization, and resilience, with specific definitions, milestones, and a coordinated roadmap and procurement programs led by the New York State Energy Research and Development Authority (NYSERDA) and the New York Public Service Commission (PSC).

Main purpose and intent

  • Create a statewide procurement target for long-duration energy storage to support a cost-effective, reliable, and clean electricity system.
  • Facilitate deployment of storage technologies that enable 100% zero-emission electricity by 2040.
  • Provide regulatory certainty and stimulate investment and economic development in LDES technologies.
  • Coordinate policy and permitting/interconnection efforts across agencies to meet the target.

Key provisions and changes

  • Definitions:

    • Long-duration energy storage (LDES): storage systems capable of storing/discharging electricity for 10 or more hours at nameplate capacity (includes inter-day and multi-day LDES).
    • Inter-day LDES: 10–24 hours at nameplate.
    • Multi-day LDES: 24+ hours at nameplate.
    • Procurement target: the incremental LDES capacity contracted under this section.
    • Authority: New York State Energy Research and Development Authority (NYSERDA).

  • Procurement target obligation:

    • By December 31, 2030, NYSERDA must contract at least 3,000 MW of incremental LDES capacity.
    • This target is split as:
    • At least 1,500 MW of inter-day LDES.
    • At least 1,500 MW of multi-day LDES.

  • Roadmap development:

    • By July 1, 2027, the PSC, in consultation with NYSERDA, must publish an LDES roadmap.
    • The roadmap will outline plans and timelines to meet the procurement target and describe mechanisms such as competitive solicitations, incentive programs, or other procurement approaches.
    • The roadmap will coordinate with relevant agencies to ensure timely permitting and interconnection.

  • Procurement programs:

    • The PSC must adopt one or more procurement programs to achieve the target.
    • These programs must commence no later than July 1, 2028.

  • Flexibility and expansion:

    • The procurement target sets minimum commitments but does not limit additional LDES deployment beyond 3,000 MW.

  • Effective date:

    • The act takes effect immediately upon enactment.

Who/what would be affected

  • State energy planners, regulators, and agencies (PSC and NYSERDA) responsible for planning, soliciting, and approving LDES projects.
  • LDES developers, manufacturers, and investors seeking to deploy inter-day and multi-day storage projects in New York.
  • Electric utilities and grid operators involved in interconnection and permitting processes.
  • Ratepayers and the broader New York economy, through potential impact on electricity costs, reliability, and resilience.

Procedural and timeline aspects

  • Roadmap publication: by July 1, 2027.
  • Procurement programs: must be adopted and begin by July 1, 2028.
  • Target deadline: December 31, 2030, for contracting at least 3,000 MW of incremental LDES capacity (1,500 MW inter-day + 1,500 MW multi-day).
  • The target is a minimum requirement; additional LDES deployment beyond 3,000 MW is permitted.

Notes

  • The bill emphasizes diversification of storage durations as part of meeting clean energy goals.
  • It seeks to balance reliability, affordability, and resilience while advancing New York’s long-term decarbonization objectives.
