The AI Data Center Power Infrastructure Market was valued at USD 32.60 billion in 2025 and is projected to reach USD 244.10 billion by 2035, reflecting a 22.3% compound annual growth rate from 2026 to 2035, according to SNS Insider. Growth is being driven by expanding hyperscale AI campuses, GPU rack power density rising from approximately 60 kW to 130 kW, adoption of 800-volt DC systems and increased use of onsite generation. Utilities are also investing in dedicated transmission lines, while data center operators are procuring high-capacity UPS systems, switchgear, transformers and distribution equipment. North America was the largest regional market, while Asia Pacific is forecast to grow at a 26.90% CAGR. The United States market was estimated at USD 13.49 billion in 2025 and is expected to reach USD 97.00 billion in 2035 at approximately 21.8% CAGR. Bloom Energy signed a master services agreement with Oracle for up to 2.8 gigawatts of solid oxide fuel cell capacity for AI data center campuses, expanding from an earlier 1.2-gigawatt agreement. Eaton disclosed nearly 20 pilot programs for medium-voltage solid-state transformers supporting 800-volt DC distribution, with hyperscaler orders expected in the second half of 2026 and shipments planned for late 2027. UPS systems held the largest component share at 29% in 2025, while facilities above 20 MW accounted for 41%, hyperscale data centers held 55%, and cloud service providers and hyperscalers represented 59% of the market. Onsite fuel cells, gas turbines and other distributed energy systems are presented as options for reducing reliance on constrained regional grids and avoiding lengthy interconnection queues.
