Data Center Transfer Switches and Switchgears Market to Reach USD 6.49 Billion by 2034 Amid AI Infrastructure Expansion

Market Estimation, Growth Drivers, and Opportunities

The global Data Center Transfer Switches and Switchgears Market was valued at USD 3.32 billion in 2025 and is projected to grow at a compound annual growth rate (CAGR) of 7.7% from 2026 to 2034, reaching nearly USD 6.49 billion by 2034. The market is gaining momentum as data centers expand to support cloud computing, artificial intelligence (AI), high-performance computing, and digital services that require continuous, reliable electricity.

Transfer switches and switchgear are essential components of data center power infrastructure. Transfer switches enable the transition between primary and backup power sources, while switchgear helps control, isolate, and protect electrical circuits. As facilities scale up, operators increasingly prioritize power redundancy, operational safety, and uninterrupted service to minimize downtime and protect critical workloads.

The expansion of hyperscale and colocation facilities, growing electricity demand, and the increasing density of AI computing infrastructure are important growth drivers. Rising energy costs are also encouraging operators to adopt intelligent power-management systems that can monitor electrical conditions, identify potential faults, and improve operational efficiency.

Significant opportunities exist in smart switchgear, automated power transfer, predictive maintenance, and digitally monitored electrical infrastructure. Manufacturers can also benefit from modular data center construction and the need to expand power capacity quickly. Solutions that improve reliability, simplify installation, and support higher electrical loads are likely to become increasingly important as data center operators modernize their facilities.

US Market Trends and Investment in 2025

The United States remained a major growth center in 2025 as AI infrastructure investment increased demand for dependable electrical distribution equipment. In March 2025, AVAIO Digital announced an agreement with Schneider Electric to procure switchgear, power distribution units, uninterruptible power supplies, and chillers for four planned AI-ready data center campuses. In November 2025, Schneider Electric and Digital Realty announced a USD 373 million supply capacity agreement covering UPS systems, low-voltage switchgear, and prefabricated power skids. These developments illustrate how power infrastructure procurement is becoming a central part of data center expansion. US federal policy also supported infrastructure development: a July 2025 executive order sought to accelerate permitting for qualifying data center projects and associated energy infrastructure, explicitly including switchgear and substations. Together, these investments and policy measures strengthen demand for scalable, resilient power systems.

Market Segmentation: Largest-Share Segments

By transfer switch type, automatic transfer switches held the largest share, accounting for 86.5% of the market in 2025. These systems monitor the primary power supply and automatically switch to an alternative source when a disruption or fluctuation occurs. Their compatibility with standby generators and ability to support continuous operations make them important for mission-critical data centers.

By switchgear type, low-voltage switchgear represented the largest segment. It is used at multiple points throughout data center electrical distribution systems, including service entrances and the input and output of uninterruptible power supply systems. Its broad range of applications and established adoption support its leading position.
