The Hidden Infrastructure Behind the AI Boom: Data Center Busways Market Set to More Than Double

Behind every AI data center announcement sits a less glamorous but equally critical question: how does all that power actually get to the racks? The global data center busways market is projected to grow from roughly $3.7 billion in 2026 to $8.6 billion by 2032, a 15.1% CAGR, as operators race to replace traditional cable-based power distribution with modular, scalable busway systems built for AI-era power demands.

Why Cabling Alone Can't Keep Up

AI and high-performance computing workloads are pushing rack power densities to levels traditional cable trays were never designed for. Busway systems let operators deliver power in a modular, plug-and-play format, cutting deployment time and giving colocation providers the flexibility to reconfigure power allocation as tenant needs change, without ripping out cabling every time a rack's requirements shift.

Who's Driving Demand

• Hyperscale data centers command the largest share of the market, backed by massive capital commitments from major cloud providers

• High-ampacity busways, rated at 1250A and above, are the fastest-growing segment as AI clusters push past traditional power distribution limits

• North America leads today on the back of its mature hyperscale ecosystem, while Asia Pacific is expected to post the fastest growth through 2032

• Established electrical equipment makers, including Schneider Electric, Legrand, Eaton, ABB, and Siemens, hold the strongest positions given their existing data center relationships

Vendors Are Racing to Keep Pace

The pace of vendor announcements this year tells its own story. Siemens has showcased AI-ready power infrastructure including scalable busway-based distribution, while Siemens and Rittal have partnered on standardized power systems for AI data centers. ABB has expanded its collaboration with VoltaGrid on AI infrastructure electrification, and Vertiv has introduced a new double-stack busway system aimed specifically at high-density AI deployments.

What It Means for the Market

Power distribution has quietly become one of the tightest bottlenecks in AI infrastructure buildout, and busways are emerging as the default answer. As hyperscalers and colocation providers consolidate procurement into framework agreements with established vendors, the busway makers with the deepest data center relationships and the broadest high-ampacity portfolios are best placed to capture share as this market accelerates toward 2032.
