AI Data Centers to Spark Energy Storage Boom: UBS

​AI Power Surge Driving Energy Storage Demand
A new UBS Securities report predicts that AI-driven data centers in the U.S. will fuel a massive energy storage “boom cycle” over the next five years, as the grid races to keep up with soaring electricity needs.

UBS analyst Yan Yishu said global energy storage demand could grow 40% year-on-year by 2026, with the U.S. leading the charge. “The demand for AI data centers in the U.S. is very robust, but electricity is the biggest bottleneck,” Yan told reporters.

Batteries: The Backbone of Renewable Power
Renewables are expected to be the only major power segment to grow significantly in the next half-decade, UBS noted. But their intermittent nature — wind and solar only produce power when conditions allow — means grids need vast new battery capacity to stabilize supply.

This surge is expected to create huge opportunities for energy storage manufacturers, especially in China, where companies already hold about 20% of the U.S. market.

Global Growth Hotspots
While the U.S. remains a key profit center, UBS sees emerging markets in the Middle East, Latin America, Africa, and Southeast Asia growing even faster — up to 30% to 50% annually. These regions, UBS said, are rapidly installing renewable power and need battery systems to match.

Political Risks and Policy Tailwinds
UBS warned that China’s position could face headwinds from President Trump’s “One Big Beautiful Bill”, which restricts the participation of foreign-controlled companies in the U.S. energy sector.

At the same time, China’s domestic reforms — particularly new market-based pricing for renewable power — could further boost its energy storage sector. The reforms allow storage projects to charge batteries when prices are low and sell power when rates rise, making them more profitable.

Yan added that even a 0.4 yuan ($0.06) per kilowatt-hour price difference can make independent storage projects financially viable. UBS also expects Chinese provinces to roll out capacity payments, rewarding battery owners for being on standby during peak demand.

The Bottom Line
UBS sees the next five years as a “boom cycle” for global energy storage, powered by AI’s explosive energy needs and the accelerating transition to renewables.

​For manufacturers, utilities, and investors, it’s not just about meeting demand — it’s about keeping the lights on in the age of artificial intelligence.
