U.S. Energy Storage Market Analysis
The U.S. energy storage market generated 48.3 GW in 2024, and this is expected to increase to 120.3 GW by 2032, advancing at a CAGR of 12.2% during 2025–2032.
This is due to the increasing integration of renewable sources of energy, such as wind and solar, which require energy storage for supply efficiency and grid stability. Tax credits and grants are other factors encouraging the adoption of energy storage systems since they are aimed at energy security and sustainability. In addition, the enhancements in lithium-ion and solid-state batteries and hydrogen storage technologies improve the efficiency and reduce the cost of electricity storage and supply.
However, the market faces certain challenges, including high fixed costs, regulatory matters, and technical complexities in the integration of distributed energy resources into the electrical grid. There is a large growth potential, with the Solar Energy Industries Association predicting battery energy storage capacity additions to rise to 119 GWh by 2030 from 18 GWh in 2022.
U.S. Energy Storage Market Emerging Trends & Growth Drivers
Grid-Scale Energy Storage Systems Are Trending
Grid-scale energy storage systems are the biggest trend in the market, as they are critical to balance the variable nature of solar and wind plants.
Bigger battery systems facilitate the balancing of supply and demand, as they eliminate power quality & frequency fluctuations help to prevent power outages, and provide stable power flow.
Grid-scale energy storage allows utilities to capture energy during low-usage times and dispense it during high-usage periods.
An increase in storage capacity supports the transition to a cleaner energy mix and helps achieve state and federal decarbonization goals.
The innovations in battery technologies, from solid-state to flow, make grid-scale storage more efficient and scalable.
One of the largest battery storage projects in the world is the Moss Landing Energy Storage Facility in California.
Completed in 2023 by Vistra, the facility has a total electricity storage capacity of 750 MW/3,000 MWh.
Supportive Policies and Falling Battery Prices Drive Market Growth
The U.S. energy storage systems market is driven by federal and state-level policies and incentives, such as the Investment Tax Credit (ITC).
These policies help offset the high initial costs and promote investment in the sector.
The ITC reimburses up to 30% of the cost for the installation of energy storage systems, making them more affordable for both residential and commercial owners.
State-level initiatives, such as California's Self Generation Incentive Program with rebates and incentives on energy storage installations, are adding to this market growth.
Over the last few years, the cost of lithium-ion batteries has drastically dropped, mainly due to economies of scale, technological advancements, increased competition, and government support.
As production ramps up, manufacturers achieve lower per-unit costs, making these batteries more affordable.
Cost reductions are also a result of the improvements in the battery technology, such as enhanced energy density and longer cycle life.
As per reports, prices dropped by 20% from 2023, reaching USD 115 per kWh in 2024.
