Busway-Bus Duct Market to Reach USD 19.75 Billion by 2032 at 5.5% CAGR

The Busway-Bus Duct Market is expanding as industrial facilities, commercial buildings, data centers and infrastructure projects require safer, flexible and space-efficient electrical power distribution. Busway systems provide a modular alternative to conventional cable-and-conduit layouts, supporting easier installation, expansion and maintenance.

Busway-Bus Duct Market Estimation, Growth Drivers and Opportunities

The Busway-Bus Duct Market was valued at USD 13.57 Billion in 2025 and is projected to reach USD 19.75 Billion by 2032, growing at a CAGR of 5.5% from 2026 to 2032. Rapid urbanization, industrial expansion, modernization of electrical networks and rising demand for reliable power distribution are major growth drivers. Data centers are becoming an important opportunity because AI workloads and high-density computing require scalable power distribution that can be expanded without extensive rewiring.

Further opportunity in the Busway-Bus Duct Market comes from retrofitting aging industrial and commercial facilities. Smart monitoring, modular tap-off units and energy metering are helping operators improve reliability and track power use. Investment in factories, metro systems, airports, offices and digital infrastructure is widening the market opportunity.

U.S. Market Trends and Investment in 2025

The United States was a major contributor to the Busway-Bus Duct Market in 2025 as data-center construction, reshoring of manufacturing and electrical infrastructure upgrades increased equipment demand. ABB announced a USD 120 million U.S. manufacturing investment in March 2025, including USD 80 million for a new 320,000-square-foot facility in Selmer, Tennessee. The site is expected to increase production capacity by more than 50% and manufacture electrical distribution equipment including busway and bus plug products. Schneider Electric separately announced more than USD 700 million of planned U.S. investment through 2027 to support energy infrastructure, AI, manufacturing and supply-chain capacity.

Busway-Bus Duct Market Segmentation

By type, non-segregated phase bus duct held the leading position in 2025. This design is widely used because it offers an economical and versatile solution for low-voltage commercial, industrial and utility applications. Its relatively simple construction supports easier installation and maintenance compared with more specialized configurations.

North America led the regional market in 2025. Data centers are also becoming an important end-use opportunity because operators require high-density, modular overhead power distribution that saves floor space and allows server racks to be added quickly.

Busway-Bus Duct Market Competitive Analysis

Competition in the Busway-Bus Duct Market centers on safety, current capacity, modularity, digital monitoring, energy efficiency and installation speed. Five prominent global participants listed by MMR are Schneider Electric, ABB, Eaton, Siemens and Legrand.

Schneider Electric introduced high-density data-center solutions in June 2025, including a prefabricated modular EcoStruxure Pod architecture integrating high-power busway, liquid cooling and high-density racks. ABB is investing directly in U.S. busway manufacturing through its new Tennessee facility.

Eaton advanced its data-center strategy with the PowerWave 2 bus system and an 800 VDC reference architecture for AI factories, incorporating busbar-based power distribution for high-density computing.

Siemens remains a major electrical infrastructure supplier serving industrial and data-center projects through its electrification and digital power-management portfolio and continues to compete in large commercial and industrial electrical distribution applications.

Legrand expanded its busway position in March 2025 by announcing the acquisition of Malaysia-based Linkk Busway Systems, a specialist in power busbars for data-center grey space generating approximately €45 million in annual revenue.
