# Data Center Microgrid Market > Data Center Microgrid Market: USD 1.17 billion in 2026, USD 3.12 billion by 2035, 17.01% CAGR from 2025 as AI campuses island from the grid. Publisher: DC Market Insights Author: Amit Jain, DC Market Insights Published: 2026-10-18 Last updated: 2026-10-18 Next review: Apr 2027 Page: https://www.dcmarketinsights.com/report/data-center-microgrid-market ## Key takeaways - Air Permits for the Generators Set the Microgrid Timeline **Frequently Asked Questions** **What is the size of the Data Center Microgrid Market in 2026?** USD 1.17 billion in 2026, up 80.4% from USD 648.05 million in 2025, according to DC Market Insights estimates. The market is projected to reach USD 3.12 billion by 2035, a CAGR of 17.01% from 2025. **How fast is the Data Center Microgrid Market growing?** 17.01% a year from 2025 to 2035, after 72.24% a year from 2020 to 2025, because islanded and bridge-to-grid microgrid capacity commissioned at data centers rises from 2,000 MW in 2025 to 6,300 MW in 2035. **What is a data center microgrid?** A data center microgrid is a set of onsite generators, batteries and loads that one controller runs as a single system, with or without the grid. DC Market Insights values its control, switchgear, integration and operating layer at USD 648.05 million in 2025. **How much does a data center microgrid cost per kW?** About USD 260 per kW for the microgrid layer of an islanded campus in 2025, or USD 26.0 million for 100 MW, before generators and batteries (DC Market Insights estimate). A grid-parallel resilience microgrid layer costs about USD 110 per kW. **Which component leads the Data Center Microgrid Market?** 41.6% of 2025 value, or USD 269.64 million, goes to switchgear, protection and islanding equipment. Operations and optimisation services grow fastest at 34.84% a year as the installed microgrid base reaches 84,844 MW in 2035. **Why are data centers building microgrids?** Grid connections for large campuses can take three to ten years, so 2,000 MW of islanded and bridge-to-grid microgrids were commissioned at data centers in 2025. Rules in Ireland and Texas also ask large loads to bring onsite dispatchable capacity. **Which region leads the Data Center Microgrid Market?** 74.0% of 2025 value, or USD 479.56 million, is spent in North America. Asia Pacific grows fastest at 26.18% a year, and India is the fastest-growing country in the top 12 at 32.63% a year. **Who are the leading data center microgrid companies?** About 12% of 2025 value is held by Schneider Electric, and the top five suppliers hold about 42% (DC Market Insights assessment). Siemens, ABB, Eaton and Hitachi Energy follow, with Caterpillar, Enchanted Rock and VoltaGrid as integrators. **What are the largest data center microgrid projects?** 9,310 MW of named projects include 4,000 MW for Joule Capital Partners in Utah, up to 2,450 MW of fuel cells for Oracle in New Mexico and 2,300 MW from VoltaGrid for Oracle in Texas. Their microgrid layer is worth about USD 2.42 billion. **Why do Data Center Microgrid Market estimates differ?** USD 1.17 billion in 2026 is the DC Market Insights figure for the microgrid layer only. Estimates that add the generators, fuel cells and batteries inside the microgrid, or fuel and electricity sales, are several times larger. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 648.05 | USD million | | Revenue CAGR | 17.01 | % | | Market size 2035 | 3,120 | USD million | ## Frequently asked questions ### What is the size of the Data Center Microgrid Market in 2026?
