Energy storage policy summary september 2025

How can energy storage be used in future states?

Target future states collaboratively developed as visions for the beneficial use of energy storage. Click on an individual state to explore identified gaps to achievement. Energy storage is essential to a clean and modern electricity grid and is positioned to enable the ambitious goals for renewable energy and power system resilience.

What are the different types of energy storage policy?

Approximately 16 states have adopted some form of energy storage policy, which broadly fall into the following categories: procurement targets, regulatory adaption, demonstration programs, financial incentives, and consumer protections. Below we give an overview of each of these energy storage policy categories.

Why was the energy storage roadmap updated in 2022?

The Energy Storage Roadmap was reviewed and updated in 2022 to refine the envisioned future states and provide more comprehensive assessments and descriptions of the progress needed (i.e., gaps) to achieve the desired 2025 vision.

What is the future of energy storage?

Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.

Should energy storage be co-optimized?

Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible. Goals that aim for zero emissions are more complex and expensive than net-zero goals that use negative emissions technologies to achieve a reduction of 100%.

How much storage capacity does Texas have in 2023?

At the end of 2023, Texas had 7.3 GW of installed storage capacity, while California had 3.2 GW of installed capacity. In 2022, CAISO, ERCOT, NYISO, PJM, and ISO-NE collectively had approximately 4.3 GW of standalone storage capacity, with another collective 24 GW expected to come online between 2024 and 2025.
