Battery Storage Firms Target AI Data Center Boom as Grid and Supply Chain Delays Slow Expansion
May 18, 2026 — Battery storage companies in the United States are seeing a major new growth opportunity from the rapid rise of artificial intelligence data centers, but the industry is also facing serious obstacles linked to grid connection delays, supply chain limits, and dependence on China for key battery materials.
According to a Reuters report, AI data centers are creating intense demand for reliable electricity because they require large amounts of power to run servers, cooling systems, and advanced computing equipment. Battery energy storage systems are now being viewed as one possible solution to help stabilize electricity use, reduce pressure on the grid, and support faster data center development.
Why AI Data Centers Need Battery Storage
AI data centers consume electricity around the clock. Unlike ordinary buildings, they often have sudden changes in power demand when computing workloads rise or fall. This makes energy management more complex.
Battery storage systems can help by storing electricity when supply is strong and releasing it when demand rises. These systems are especially useful in areas with high renewable energy use, such as California, where solar power production falls in the evening while electricity demand remains high.
For data centers, batteries can be used in two main ways. When placed in front of the meter, they can support the wider grid and improve use of transmission lines. When installed behind the meter, they can help a data center manage demand spikes, reduce grid stress, provide temporary backup power, and lower reliance on diesel generators.
Power Demand Is Expected to Rise Sharply
Industry estimates show that data centers could account for a much larger share of U.S. electricity demand by 2030. The Electric Power Research Institute has estimated that data centers may consume between 9% and 17% of U.S. electricity supply by the end of the decade, compared with about 4% today.
This expected jump is creating strong interest in battery storage. The U.S. added a record 57.6 gigawatt-hours of new battery storage capacity in 2025, bringing total deployed capacity to 166.1 gigawatt-hours, according to the Solar Energy Industries Association. The group expects annual battery storage deployments to reach 110 gigawatt-hours by 2030.
Major Companies Are Moving Into the Market
Battery storage firms are already seeing strong demand from data center operators and large technology companies. Fluence, a major energy storage company, has said it is involved in more than 30 gigawatt-hours of data center-related projects worldwide, with a meaningful share located in the United States.
Tesla has also benefited from the trend. Reuters reported that Tesla generated $430 million in revenue last year from selling storage systems to xAI, Elon Musk’s artificial intelligence company.
Another example is Calibrant Energy, which has agreed to provide a 31-megawatt / 62-megawatt-hour battery energy storage system for an Aligned data center campus in the Pacific Northwest.
Grid Connection Delays Remain a Major Problem
Even though demand is rising, battery storage companies cannot always move quickly. One of the biggest challenges is the long wait to connect new projects to the electricity grid.
In some parts of the United States, data centers can be built in about 18 to 24 months, but connecting them to the grid can take three to seven years. This delay makes it harder for battery storage projects to support AI power demand at the speed the market needs.
PJM Interconnection, the largest grid operator in the U.S., paused new grid connection applications in 2022 after becoming overloaded with project requests. It has only recently started accepting new applications again.
Supply Chain Dependence on China Creates Another Hurdle
Another major challenge is the battery supply chain. The U.S. is trying to expand domestic lithium iron phosphate battery manufacturing, but many key materials still depend heavily on China.
This creates a difficult situation for companies that want to qualify for U.S. tax incentives, especially as rules increasingly encourage or require non-China sourcing. Analysts say the shift could help grow American battery manufacturing, but the supply base outside China still needs more development.
Why Batteries May Work With Natural Gas Power
Battery systems may also play an important role alongside natural gas generation. Many data centers are exploring onsite gas-fired power because of their large and steady electricity needs.
However, gas generators may not respond quickly enough to sudden changes in AI computing demand. Batteries can fill that gap by reacting faster, helping smooth out power swings and keeping energy supply stable.
Industry Outlook
The battery storage industry appears to be entering a new phase of growth as AI data centers expand across the United States. Demand from technology companies could become one of the strongest drivers of future battery deployment.
Still, the opportunity depends on solving major infrastructure problems. Faster grid interconnection, stronger domestic manufacturing, and more secure supply chains will be key factors in determining how quickly battery storage can meet AI-related power demand.
