Delray Beach – October 28, 2026 -- The global switchgear monitoring system market will grow from USD 2.36 billion in 2026 to USD 3.80 billion by 2031, a compound annual growth rate (CAGR) of 10.1%, according to MarketsandMarkets. The market stood at USD 2.17 billion in 2025.
Asia Pacific is forecast to post the fastest regional CAGR at 10.6%
Rapid electrification, renewable energy development and industrialization in Asia Pacific, the Middle East and other emerging markets are creating additional growth opportunities. North America, Europe and Asia Pacific remain the key markets, backed by extensive power infrastructure and ongoing grid modernization.
Gas-insulated switchgear held 67.9% of the market in 2025
Gas-insulated switchgear (GIS) is also expected to grow faster than air-insulated switchgear (AIS). Compact high-voltage substations, urban power infrastructure, renewable projects and space-constrained facilities drive that growth. GIS installations let operators build in gas-density monitoring, partial discharge detection, temperature monitoring, fault detection and remote diagnostics from the design stage.
AIS remains significant because of its large installed base across utility substations, industrial facilities, commercial buildings and distribution networks. Monitoring there helps operators detect abnormal temperatures and insulation degradation and extend the service life of existing equipment.
By component, software is expected to register the highest CAGR at 8.8%. By voltage, the low-voltage segment is expected to grow fastest.
Utilities are projected to hold the largest end-user share in 2031
Utilities deploy monitoring across transmission and distribution networks, substations and grid infrastructure to identify potential failures before they cause equipment damage or unplanned outages. Developing markets are building new transmission lines and substations and integrating renewables, which allows monitoring to be installed alongside new switchgear. Mature markets are replacing aging switchgear and upgrading substations, a process that creates recurring demand.
Utilities also face pressure to improve asset utilization, cut maintenance costs and minimize service interruptions. That pressure is pushing adoption of IoT-enabled sensors, thermal monitoring, partial discharge detection, remote diagnostics and predictive analytics. Growing volumes of renewable energy, distributed generation, battery storage and digital substations add further requirements for intelligent monitoring.
Europe is expected to rank as the second-largest region
Germany, the UK, France, Italy, Spain and the Netherlands are investing in transmission and distribution networks, digital substations, offshore wind and smart-grid infrastructure. Germany, the UK and France are singled out as particularly important markets. Offshore wind and other renewable projects across Northern and Western Europe raise the need for reliable monitoring of switchgear in substations and grid connection infrastructure.
IEA projects USD 3.4 trillion in global energy investment in 2026
The IEA estimates that annual grid investment, currently around USD 400 billion, must rise by roughly 50% by 2030 to meet projected electricity demand. MarketsandMarkets names Schneider Electric, Siemens, Eaton, GE Vernova, ABB, Hitachi, Mitsubishi Electric, Emerson Electric and Megger among the leading vendors. They compete on condition-monitoring portfolios, sensor technology, partial discharge and thermal monitoring, remote platforms and predictive maintenance.
