The US storage sector experienced significant growth in 2024 and 2025. Approximately 12 gigawatts (GW) of utility-scale storage capacity was deployed in 2024, representing one of the largest annual increases on record. Growth continued in 2025, with approximately 19 GW forecasted to be installed. Industry forecasts project that installations may falter slightly in 2026, but development will pick up again in the near term with approximately 93 GW expected to be installed in the next five years.

Technology diligence, construction risk allocation, merchant revenue underwriting, and evolving tax equity rules are shaping how energy storage projects are financed worldwide. Both the US and global energy storage markets have experienced rapid growth over the last year and are expected to continue expanding rapidly in order to support grid resiliency.

Procurement mandates, incentive programs, regulatory reforms, and safety standards continue to shape state-level energy storage deployment across the United States. Energy storage resources have become an increasingly important component of the US energy mix as traditional fossil fuel baseload generation gives way to renewable energy resources. As of 2025, 24 states, plus the District of Columbia and Puerto Rico, have adopted 100% clean or carbon-free energy goals.
