Government policies play a central role in accelerating long-duration energy storage (LDES) adoption by providing regulatory frameworks, funding mechanisms, and procurement mandates to address technical and economic barriers.
Regulatory Mandates and Procurement Targets
States like California have implemented binding procurement requirements, such as the CPUC’s 1 GW LDES mandate (12+ hour duration) by 2031–2037 to meet its 100% carbon-free electricity goal by 2045. Over a dozen states now include energy storage in policy frameworks, with recent LDES-specific targets emerging in some regions.
Financial Incentives and R&D Funding
California’s $330 million LDES program directly funds pilot projects and technological innovation, while federal initiatives like the U.S. Department of Energy’s LDES programs prioritize cost reductions and scalability. These efforts aim to bridge the gap between demonstration projects and commercial viability.
Grid Planning and Market Reforms
Policies increasingly focus on modeling LDES requirements for high-renewable grids. For example, California’s 2016 analysis identified the need for 2 GW of 10+ hour storage to achieve 60% renewable penetration by 2030, directly informing later mandates. State-level procurement strategies also create predictable demand, encouraging private investment.
Equity and Accessibility
Emerging policies incorporate equity provisions, such as prioritizing disadvantaged communities in procurement processes or requiring location-specific deployment to enhance grid resilience.
By aligning mandates, funding, and market signals, governments reduce risks for developers and utilities, enabling LDES to scale as a critical solution for grid reliability during deep decarbonization.
