The Data Center Grid Interconnection Equipment Market was valued at USD 4.04 billion in 2025 and is estimated at USD 4.41 billion in 2026. It is projected to reach USD 7.48 billion by 2032, growing at a CAGR of 9.2% during 2026-2032.
The logic is simple. A new data hall cannot draw power until its connection to the utility grid is specified, procured, and energized, so hyperscale operators and colocation developers are buying transformers, switchgear, and protection systems at that connection point.
Load growth is doing the pushing. The International Energy Agency reported that global data center electricity demand rose 17% in 2025, nearly six times the 3% growth in overall electricity demand that year. Each new gigawatt of data center load needs its own step-up transformers, high-voltage switchgear, and protection relays at the interconnection point. Developers are ordering more grid interconnection equipment simply to keep pace with load growth already underway.
Key Insights
Transformers led the equipment mix with a 37% share in 2025. Every point of interconnection needs at least one purpose-built unit sized to the campus's contracted load, and long lead times mean developers commit this spending earliest in the design cycle.
Switchgear and circuit breakers is the faster mover, projected to grow at a 9.9% CAGR during 2026-2032. Utilities increasingly demand redundant protection paths before they energize a large new load, which means more breaker positions per connection.
High voltage equipment (35-230 kV) accounted for 46% of 2025 revenue. The extra-high voltage tier above 230 kV is growing quicker, at an 11.0% CAGR during 2026-2032, as campuses drawing several hundred megawatts tie directly into transmission backbones.
Hyperscale operators held 46% of 2025 revenue, helped by direct purchasing control over equipment on their side of the meter. Edge and micro data centers are set to grow fastest, since every new site needs its own protection and interconnection equipment.
Greenfield new builds took 53% of 2025 revenue because a new campus orders its full equipment package in one procurement event. Brownfield upgrades and expansions should grow faster, as campuses built five to ten years ago are requalified for heavier AI workloads.
North America accounted for 38% of 2025 revenue. Hyperscale campuses cluster in northern Virginia, Texas, and the Pacific Northwest, and congestion around those hubs is pushing utilities to upgrade existing interconnection points.
Asia-Pacific is the fastest-growing region, expanding at a 10.5% CAGR during 2026-2032. Most capacity there is added on greenfield sites, so nearly every campus needs its equipment installed from scratch. India's Central Electricity Authority is also directing states and distribution utilities to fold projected data center demand into transmission planning.
Europe's established hubs are constrained by grid capacity rather than land or capital. The European Network of Transmission System Operators for Electricity expects regional data center electricity demand to grow more than 50% between 2025 and 2030, and it names connection lead times as the sector's most frequently cited constraint.
Policy is speeding up orders. The Federal Energy Regulatory Commission ordered PJM Interconnection in December 2025 to rewrite its tariff for co-located load, including provisional service that lets construction begin before every study is complete. Queues still bite, though: projects above 100 megawatts now take a median of more than four years from interconnection request to commercial operation, according to Lawrence Berkeley National Laboratory.
The market is moderately fragmented, with 11 established suppliers and no dominant player. ABB Ltd, Schneider Electric SE, Eaton Corporation plc, Siemens Energy AG, Hitachi Energy Ltd., GE Vernova Inc., and Mitsubishi Electric Corporation compete on portfolio breadth. Vertiv Holdings Co., Toshiba Corporation, Powell Industries, Inc., and Hyosung Heavy Industries Corporation compete on delivery speed and regional manufacturing footprint.
Capital is following demand. In September 2026, Hitachi Energy Ltd. committed USD 528 million to a power transformer plant in Gallman, Mississippi, and Vertiv Holdings Co. agreed to acquire UtilityInnovation Group for up to USD 2.6 billion.
