Key Updates:
The Solar Energy Industries Association (SEIA) has announced a bold plan for the United States to significantly expand its energy storage capabilities. The goal is to install 10 million distributed energy storage systems and achieve a total storage capacity of 700 gigawatt-hours (GWh) by the year 2030.
To support this initiative, SEIA released a national energy storage policy guide that provides insights into current laws, deployment targets, incentives from states and utilities, demonstration programs, and protections for consumers engaging with energy storage.
With increasing demands for power and a growing percentage of renewable energy, the SEIA emphasizes the urgent need for enhanced energy storage capacity. Abigail Ross Hopper, SEIA’s President and CEO, remarked that achieving these targets is critical for ensuring the reliability of power across communities and adapting to evolving grid challenges.
Current Energy Storage Landscape:
Currently, there are nearly 500,000 distributed energy storage systems in operation in the U.S., amounting to about 83 GWh of total capacity, according to SEIA’s data from Wood Mackenzie. The recent targets indicate a more than 20-fold increase in installations and an eight-fold increase in total capacity needed by 2030, which exceeds current forecasts.
The latest Energy Storage Monitor from Wood Mackenzie highlights that U.S. storage deployments hit a record 9.9 GWh in the fourth quarter of 2024, showing a remarkable growth of 58% compared to the same period the previous year. For all of 2024, a 30% increase in deployments was noted, making it a breakthrough year for the industry. Wood Mackenzie’s analysis suggests that maintaining such growth rates may be challenging due to early-stage development constraints, forecasting an average annual growth of 10% from 2025 to 2028.
Segments and Future Development:
Utility-scale storage systems dominate the current market, making up about 9 GW of total deployments in late 2024. In contrast, community and commercial installations saw only a modest growth, totaling 29 MW, which represented a decline from the previous year.
SEIA states that more storage solutions are crucial for enhancing grid reliability, especially in light of the anticipated growth in renewable energy integration by 2030. Their recent whitepaper indicates a recommended distribution of energy storage, suggesting that 20% should be located in residential, commercial, and community areas, with 80% linked to transmission systems.
As of late 2023, lower raw material costs have brought down the prices of both residential and utility-scale energy storage systems significantly. SEIA anticipates that new battery technologies, such as iron-air batteries, could further accelerate installations.
However, reaching these ambitious targets will require solid policy support. SEIA urges for quicker implementation of specific federal regulatory orders and more favorable valuations of storage’s contributions. They advocate for states to spearhead storage procurement with effective incentives, amid efforts to secure federal clean energy tax credits.
