UBS: AI Data Centres to Power Global Energy Storage Boom Over Next Five Years
The surge in AI data centre power demand across the United States is set to trigger a “boom cycle” for energy storage over the next five years, according to a new report from UBS Securities.
UBS analyst Yan Yishu, speaking at a media briefing in Hong Kong, said global energy storage demand could grow 40% year-on-year in 2026, as the U.S. grid increasingly depends on batteries to manage fluctuations from wind and solar power.
“The demand for AI data centres in the U.S. is very robust, but electricity is the biggest bottleneck,” Yan said. As renewables remain the only U.S. power segment expected to expand significantly in the coming years, large-scale energy storage systems will be critical to balancing intermittent supply with rising consumption.
The U.S. remains a key market for Chinese energy storage firms, which hold about 20% market share there, drawn by high profit margins. However, Yan warned that President Trump’s One Big Beautiful Bill, which restricts Chinese participation in U.S. energy infrastructure, could pose serious risks to future exports.
Meanwhile, emerging markets including the Middle East, Latin America, Africa, and Southeast Asia are expected to record 30–50% growth rates or higher as renewable integration accelerates.
In China, policy reforms encouraging market-based electricity pricing are also driving new storage investments. Yan noted that a peak-to-valley price gap of 0.4 yuan ($0.06) per kWh is already enough to make standalone storage projects profitable. UBS expects provincial governments to introduce capacity payments, rewarding battery operators for availability during peak demand, further fueling growth.
