The global data center transfer switches and switchgears market size was valued at USD 3.01 billion in 2023 and is projected to reach USD 5.42 billion by 2030, growing at a robust CAGR of 9.2% from 2024 to 2030. This growth is primarily driven by the rapid expansion of data centers worldwide, the increasing need for uninterrupted power supply, and the rising emphasis on energy efficiency and sustainability. As the global demand for cloud computing, big data analytics, artificial intelligence, and digital services continues to surge, data centers are multiplying and scaling up, requiring highly reliable and resilient power infrastructures to ensure uninterrupted operations.

The growing complexity of data center operations is another key factor influencing market growth. Modern data centers are no longer limited to basic storage and processing functions. Instead, they are evolving into multi-functional hubs that handle diverse workloads, including AI applications, machine learning algorithms, and high-performance computing (HPC). These workloads come with varying and unpredictable power requirements. To address these challenges, operators rely on advanced transfer switches and switchgears that can support flexible power distribution strategies, manage fluctuating loads, and ensure redundancy for maximum uptime.

Energy efficiency and sustainability have also become central to the data center industry, which is among the largest consumers of electricity globally. Operators are under increasing pressure to adopt greener technologies that not only reduce energy consumption but also minimize the carbon footprint. In this context, modern transfer switches and switchgears are being designed to optimize power distribution, minimize energy losses, and improve system efficiency. Additionally, with more data centers integrating renewable energy sources such as solar and wind into their operations, there is a rising demand for switchgear solutions capable of handling diverse and variable power inputs while maintaining reliability and stability.

Key Market Trends & Insights:

• Regional Outlook: North America dominated the market in 2023, accounting for the largest revenue share of 36.5%, supported by the presence of large-scale data centers, advanced IT infrastructure, and major technology companies. However, the Asia Pacific region is projected to register the fastest CAGR during the forecast period, driven by rapid digital transformation, government initiatives for green data centers, and the explosive growth of cloud service providers in countries such as China, India, and Singapore.
• By Transfer Switch: The static transfer switches (STS) segment held the largest revenue share at 38.3% in 2023, owing to their ability to provide fast and seamless switching between power sources, ensuring high uptime for mission-critical applications. The service entrance transfer switches segment is expected to grow at the fastest CAGR, as these switches are increasingly being adopted to enhance safety and compliance with regulatory standards.
• By Switchgear: The low-voltage power control system segment accounted for the largest market revenue share in 2023, reflecting its widespread use in standard data center operations. Meanwhile, the medium-voltage power control system segment is expected to grow at the fastest rate, as large-scale hyperscale data centers increasingly require medium-voltage solutions to manage greater loads and enhance efficiency.
