The global battery storage for data centers market size was USD 3.72 Billion in 2025 and is expected to register a revenue CAGR of 24.6% during the forecast period. Market revenue growth is supported by the International Energy Agency's projection, cited in Electrovaya's July 2026 product filing, that data center electricity demand will more than double by 2030, at a time when JLL's 2026 Global Data Center Outlook reports that the average wait time for a utility grid connection in primary data center hubs now exceeds four years. Regulatory drivers including Texas Senate Bill 6, which incentivizes on-site dispatchable power for loads exceeding 50 MVA, and the National Electrical Manufacturers Association's January 2026 publication of Data Center Design Considerations for Energy Storage Systems, are giving operators standardized reference architectures for integrating battery energy storage into new campus power topologies rather than relying on bespoke, one-off engineering for every site. Hyperscaler capital commitments at gigawatt scale, including Energy Vault's August 2026 agreement to supply 1.25 gigawatts of integrated battery storage and grid-forming power infrastructure for a Texas AI data center, are converting battery storage from a backup line item into a primary capital allocation decision. These are some of the key factors driving revenue growth of the market.
Lithium-ion battery cabinets and grid-scale BESS units, nickel-zinc and alternative long-duration chemistry systems, and the power conversion, controls software and EPC integration services that connect them to a data center's electrical topology are the commercial categories that constitute the battery storage for data centers market, with hyperscale operators increasingly specifying storage capacity and duration at the masterplanning stage rather than value-engineering it in later. For instance, in August 2026, Energy Vault, United States, announced a strategic commercial agreement to supply battery energy storage systems, grid-forming power conversion systems and AI infrastructure control software for an initial 1.25 gigawatt deployment backed by a hyperscaler customer contract in Texas, with the company disclosing an expected revenue impact of USD 500 million to USD 600 million across the second half of 2026 and 2027.
However, the reliance on lithium-ion chemistry at gigawatt scale is being challenged by fire safety code compliance requirements and supply chain constraints, prompting a shift toward nickel-zinc and other non-lithium alternatives that mitigate thermal runaway risk while matching the discharge rates AI load ramping requires. Federal tax credit eligibility under the 48E Investment Tax Credit carries foreign entity of concern compliance requirements that add sourcing and documentation complexity to battery procurement, while the Federal Energy Regulatory Commission's still-pending rules on transmission cost allocation for storage assets co-located with data center facilities leave open how much grid-services revenue a given battery deployment can actually earn. Alternative long-duration chemistries such as iron-air and ultra-long-duration systems remain commercially unproven at scale relative to lithium-ion, with the largest disclosed deployments only reaching first construction or reservation agreements during 2026. These factors substantially limit battery storage for data centers market growth over the forecast period.
Based on chemistry type, the global battery storage for data centers market is segmented into lithium-ion (LFP) technology, lead-acid and VRLA legacy technology, nickel-zinc technology, alternative long-duration chemistry, and other emerging chemistries. The lithium-ion (LFP) technology segment commands the largest revenue share because it is the default chemistry for the utility-scale battery energy storage systems hyperscalers are deploying at gigawatt scale, with Tesla's Megablock configuration, built on its third-generation Megapack, delivering 20 megawatt-hour clusters from a Houston, Texas manufacturing facility with capacity to produce up to 50 gigawatt-hours of Megapack and Megablock units per year. Lithium iron phosphate chemistry's thermal stability, established supply chain and multi-decade manufacturing scale give it a cost and lead-time advantage over newer chemistries for the standard two-to-four-hour duration systems most data center behind-the-meter deployments currently specify.
The alternative long-duration chemistry segment is expected to register a rapid revenue growth rate in the global battery storage for data centers market over the forecast period. Google's February 2026 agreement with Form Energy to build a 300 megawatt, 30 gigawatt-hour iron-air battery capable of delivering its rated power for 100 hours to a new Minnesota data center, and Meta's April 2026 agreement with Noon Energy reserving up to 100 gigawatt-hours of ultra-long-duration energy storage capacity for its data center infrastructure, illustrate how AI workloads' need for continuous, multi-day power availability is pulling capital toward chemistries that lithium-ion's typical duration range cannot economically match.
Based on regional analysis, the battery storage for data centers market in North America accounted for the largest revenue share in 2025. The United States is the dominant country, with Google's 1.9 gigawatt clean power agreement in Minnesota, including the 300 megawatt, 30 gigawatt-hour Form Energy iron-air battery announced in February 2026, and Meta's 2.5 gigawatt renewable energy portfolio with NextEra Energy, structured as 13 individual contracts including two dedicated energy storage agreements, representing the largest disclosed hyperscaler storage commitments in the region. Microsoft's grid-interactive EnergyAware uninterruptible power supply agreement with Eaton, confirmed in February 2026, lets the company's data center UPS battery banks respond to utility control signals and participate in grid-stabilizing initiatives across key markets rather than sitting idle between outages. Texas has emerged as a primary deployment hub under Senate Bill 6's on-site dispatchable power incentive, with Energy Vault's 1.25 gigawatt hyperscaler agreement and multiple additional gigawatt-scale projects concentrated in the Electric Reliability Council of Texas service territory. The region's regulatory uncertainty centers on how the Federal Energy Regulatory Commission ultimately allocates transmission costs for battery assets co-located with data center facilities.
The European battery storage for data centers market is expected to register rapid revenue growth over the forecast period. Tesla's June 2026 agreement with NatPower secured a defined multi-year Megapack rollout tied to grid reliability and renewable integration goals in Italy and the United Kingdom, structured as a 25 gigawatt-hour deployment pipeline that gives Tesla's European energy storage business a committed order book independent of any single data center campus. European Union data center capacity is expanding from a smaller installed base than the United States, and data center operators face additional pressure to pair battery storage with renewable power procurement to meet corporate and regulatory sustainability commitments that are more binding in the European Union than in North America. The region's data center energy storage buildout remains concentrated in markets with the strongest existing renewable generation infrastructure, since battery storage economics for data centers improve substantially when paired with co-located wind or solar rather than deployed as a standalone grid-charged asset.
The battery storage for data centers market in Asia Pacific is expected to register rapid revenue growth, though from a smaller base of disclosed hyperscaler-specific storage contracts than North America. China's domestic battery storage sector underwent a structural policy shift during 2025 and 2026, with Ember's July 2026 analysis confirming the end of mandatory storage co-location for renewables in 2025 and the expansion of capacity remuneration to include battery energy storage systems in 2026, moving the country's stationary storage market from an administratively mandated model toward a more market-driven one that data center operators can increasingly participate in directly. Singapore's data center market, valued at USD 3.25 Billion in 2025, continues to expand following the 2022 lifting of its construction moratorium, though land scarcity and power constraints are pushing new campuses toward higher-density designs that increase the battery storage capacity required per megawatt of IT load. Japan and South Korea's data center operators remain more reliant on grid power and diesel backup than on dedicated battery energy storage relative to their North American counterparts, reflecting more stable grid interconnection timelines in both markets.
The battery storage for data centers market in Latin America is expected to register moderate revenue growth from a low base, with Brazil and Mexico representing the primary data center markets attracting hyperscaler investment in the region. Grid reliability challenges in several Latin American power markets create a stronger underlying case for behind-the-meter battery storage than in regions with more stable utility interconnection processes, but the region has not yet produced a disclosed hyperscaler battery storage agreement at the gigawatt scale confirmed in the United States, Texas or Minnesota deployments covered elsewhere in this report. Data center operators in the region continue to rely primarily on diesel generator backup and shorter-duration uninterruptible power supply battery banks rather than the grid-services-oriented battery energy storage systems increasingly standard in North American and European hyperscale campuses.
The battery storage for data centers market in the Middle East and Africa is expected to register limited revenue growth from a low base, with the United Arab Emirates and Saudi Arabia representing the region's most active data center investment markets as both countries pursue sovereign AI infrastructure ambitions. Regional data center operators have prioritized securing firm power generation capacity, including gas and nuclear, ahead of battery energy storage system deployment, reflecting an earlier stage of grid interconnection maturity than the queue-driven battery adoption pattern seen in North America. This report does not extend the Strait of Hormuz-related supply chain disruption referenced in other Faradex Partners battery reports to the battery storage for data centers market, since the region's data center battery deployments remain too early-stage for a regional shipping disruption to have a material, currently disclosed impact on project timelines.
