The market is projected to reach USD 1.31 billion by 2035, a CAGR of 10.29% from 2025. **How fast is the data center load bank market growing?** 10.29% a year from 2025 to 2035, after 19.69% a year from 2020 to 2025, because new IT capacity commissioned each year rises from 12.0 GW to 27.0 GW and installed capacity from 116 GW to 311 GW. **What is a load bank used for in a data center?** USD 273.60 million of 2025 spend paid for commissioning and integrated systems testing, where load banks make full rated heat and power draw before servers arrive. The rest paid for generator and UPS tests and permanently installed units. **How much does load bank testing cost per MW?** About USD 20,000 per new MW for an air-cooled hall and USD 28,000 per MW for a liquid-cooled AI hall in 2025 (DC Market Insights estimates). A 10 MW hall costs about USD 200,000 or USD 280,000 to commission. **How often must a data center generator be load bank tested?** Monthly for 30 minutes at 30% of nameplate under NFPA 110, or an annual test at 50% for 30 minutes and 75% for one hour. EPA rules allow 100 hours a year of testing, so load banks make each run count. **What is a liquid-cooled load bank?** A load bank that puts 240 kW to 720 kW of heat straight into a facility coolant loop. Liquid-cooled units grow fastest, 16.11% a year from USD 33.60 million in 2025 to USD 149.69 million in 2035. **Is it better to rent or buy load banks for data center commissioning?** Rental with operators took 69.1% of 2025 spend, USD 339.74 million, because a hall needs its full load bank capacity for only three or four weeks. Operators commissioning four or more halls a year increasingly buy. **Which region leads the data center load bank market?** North America, with USD 221.19 million or 45.0% of 2025 spend. Asia Pacific grows fastest at 12.98% a year, and India is the fastest large country at 17.66% a year. **Who are the leading data center load bank suppliers?** Avtron Power Solutions (Legrand), Aggreko with Crestchic, Sunbelt Rentals, United Rentals and Herc Rentals hold about 55% of 2025 spend (DC Market Insights estimate). Avtron expected nearly USD 350 million of 2025 revenue. **Why do data center load bank market estimates differ?** USD 581.73 million in 2026 is the DC Market Insights figure for data center load bank purchase, hire and permanent units only. Estimates that add hospital, marine and military load banks or commissioning agent fees come out larger. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 491.52 | USD million | | Revenue CAGR | 10.29 | % | | Market size 2035 | 1,310 | USD million | ## Frequently asked questions ### What is the size of the Data Center Load Bank Market in 2026?
