State-specific regulations significantly influence utility-scale energy storage deployment through procurement mandates, regulatory adaptations, and financial incentives designed to integrate storage into grid infrastructure.
Procurement Targets
Twelve states—including California, Nevada, and New York—have implemented binding storage procurement targets requiring utilities to acquire specified storage capacities by deadlines (e.g., California’s 1,825 MW by 2020 and Nevada’s 1,000 MW by 2030). These mandates drive immediate investment and demonstrate storage’s viability for grid services.
Regulatory Adaptation
States like Arizona, Colorado, and Massachusetts now require integrated resource plans (IRPs) to include storage, ensuring utilities evaluate storage as part of long-term grid planning. Additionally, updated rate structures and market rules in states such as California enable storage to participate in wholesale markets for ancillary services, enhancing project economics.
Financial Incentives and Policy Synergy
Many states with storage policies (e.g., Oregon, Maryland) pair mandates with renewable portfolio standards (RPS) or tax credits, creating complementary revenue streams. For example, Hawaii addresses cost uncertainties through pilot programs and regulatory carve-outs to encourage longer-duration storage.
Key Challenges
- Market Design: Storage’s dual role as generation/load requires regulatory clarity on participation rules.
- Cost Recovery: States must define how utilities recover storage investments, balancing ratepayer impacts and deployment speed.
- Scalability: Policies often lack mechanisms to transition from initial procurement targets to market-driven deployment.
States prioritizing technology-neutral mandates and flexible market integration (e.g., California’s AB 2514) have seen faster adoption, while others rely on pilot projects to build stakeholder confidence.
