States are increasingly prioritizing long-duration energy storage (LDES) to support decarbonization, with California and New York leading in ambition:
- California:
- LDES procurement: 2 GW by 2031–2037 (1 GW for ≥12-hour storage and 1 GW for multi-day storage).
- Existing progress: ~2,500 MW of battery storage deployed by 2021, now shifting focus to LDES (≥8 hours).
- Funding: A $2 million grant approved in December 2024 for LDES projects.
- New York:
- Storage target: 6 GW by 2030 (doubled from 3 GW in 2022).
- Policy focus: LDES integration in recent roadmaps to address multi-day renewable intermittency.
Other states with notable targets include:
- Massachusetts: 1,000 MWh by 2025 (though shorter duration and smaller scale).
- National goal: SEIA’s 700 GWh target by 2030 (includes all storage types).
California and New York stand out for pairing aggressive LDES policies with funding and procurement mandates specifically targeting multi-day storage capabilities.
