AI-Fueled Data Center Boom Ignites Unprecedented Demand for Gas-Insulated Switchgear

The voracious energy appetite of data centers, supercharged by the AI revolution, stands as a primary catalyst for demand in the gas insulated switchgear market. An estimated 10 GW of new data center capacity is estimated to break ground globally in 2025, representing about US$ 170 billion in asset value that requires secure and efficient power. In the United States, data center power demand is forecasted to contribute up to 60% of all electricity load growth between 2023 and 2030. Highlighting this, California's largest utility, PG&E, reported a staggering 40% rise in power supply requests from data centers in 2025. This trend is global, with NTT Global Data Centers investing US$ 10 billion to expand its footprint by more than 370 megawatts, and India's market projected to exceed 4,500 megawatts by 2030, backed by US$ 25 billion in investments.

Powering Clean Energy from Sea to Shore Spurs Investment in High-Voltage Substations

The worldwide transition to clean energy, particularly offshore wind, necessitates advanced gas insulated switchgear technology for high-voltage substations that transmit power from sea to land. Europe gas insulated switchgear market is leading this charge, with an expected investment of US$ 20 billion for the installation of 137 offshore substations by 2030, over 120 of which are scheduled for installation between 2024 and 2030. Projects like the DolWin4 and BorWin4 offshore grid connections in Germany, with a combined capacity of 1,800 MW, depend on sophisticated AC cable infrastructure. The scale is immense, with ScottishPower Renewables awarding a contract for a high-voltage substation weighing about 5,100 tons for its East Anglia TWO wind farm. In Poland, the 390 MW BC-Wind offshore project will require a new onshore substation to step up voltage to 400 kV.

Compact by Design, Indoor GIS Redefines Reliability in Dense Environments

The global gas insulated switchgear market is increasingly being shaped by the dominance of indoor installations, a trend boosted by relentless urbanization and the modernization of power infrastructure. The segment is currently controlling more than 57% market share. As cities expand and industrial zones become more concentrated, the demand for space-efficient and highly reliable power distribution solutions has surged. Indoor Gas Insulated Switchgear (GIS) directly addresses this need, offering a significantly smaller footprint compared to conventional Air-Insulated Switchgear (AIS). This compactness is not merely a convenience but a critical enabler for placing important substations in space-constrained locations like building basements and underground vaults, ensuring that power infrastructure can grow in lockstep with urban development. The improved safety and reliability of its enclosed design, which protects critical components from environmental degradation, further solidifies its position as the preferred choice for ensuring an uninterrupted power supply in critical applications.

The strategic value and growing preference for the indoor gas insulated switchgear market are underscored by tangible market movements and applications. The technology's adoption is a direct response to the practical challenges of modernizing and expanding power grids in dense environments.

High-Voltage Transmission Relies on the Strength of the 170 kV–550 kV Segment.

Within the gas insulated switchgear market, the 170 kV - 550 kV voltage range stands as the most prominent segment by capturing over 36% market share, fundamentally serving as the backbone for high-voltage power transmission across the globe. This segment's dominance is intrinsically linked to the important task of moving bulk power from generation sources to consumption centers efficiently. As global electricity demand climbs and nations invest heavily in expanding and upgrading their power grids, the demand for reliable switchgear in this specific voltage class intensifies. This range delivers the optimal balance between high power-carrying capacity and minimized transmission losses, making it the standard for long-distance energy transport and critical grid interconnections. Its role is further amplified by the global push towards integrating large-scale renewable energy projects, which usually need strong transmission infrastructure to connect remote generation sites to the main grid.

The significance of the 170 kV - 550 kV segment is consistently reinforced by industry innovation and strategic investments from key market players. The continuous development and deployment within this range in the gas insulated switchgear market highlight its critical significance to the stability and future-readiness of national power systems.

Ultimately, the 170 kV - 550 kV range is not just a market leader by volume; it is the technological heart of modern power transmission. Its continued prominence in the gas insulated switchgear market is assured as it is central to the dual objectives of modernizing aging grid infrastructure and facilitating the transition to a more sustainable energy future. The investments in smart grid technologies and the development of ultra-high-voltage systems, which often build upon the 550 kV level, further cement this segment's foundational role for years to come.

Massive Grid Expansion in Asia-Pacific Redefines the Future of Gas Insulated Switchgear

The future of the gas insulated switchgear market is being forged in the Asia-Pacific, where monumental government-led investments are making unprecedented demand. As a result, the region controls the largest 35% market share. This growth and dominance are authoritatively led by the State Grid Corporation of China, which has pledged a record 650 billion yuan (US$ 89 billion) for grid upgrades in 2025. This commitment is built on proven execution, including the completion of 3 new ultra-high voltage power lines in 2024, advancing its national total to 38. The investment penetrates deep into regional grids, evidenced by Qinghai province’s CNY 2.852 billion allocation for 2024, of which CNY 1.584 billion directly funds 27 projects at the 110 kV level and 33 projects at the 35 kV level.

The trend is region-wide visible in the gas insulated switchgear market, with India’s ₹111 lakh crore (US$ 1.4 trillion) National Infrastructure Pipeline and Australia’s US$ 22.7 billion Future Made in Australia plan delivering powerful tailwinds. Australia’s Central-West Orana Renewable Energy Zone, a US$ 20 billion project, will add 4.5 gigawatts of capacity by 2028, requiring 90 km of 500 kV and 150 km of 330 kV lines infrastructure that inherently relies on advanced gas insulated switchgear. This is further amplified by Queensland's REZ Roadmap, which targets 22 GW of new renewables by 2035.

The region's expertise is also being exported, with State Grid undertaking a US$ 3.6 billion project in Brazil to construct a 1,500 km transmission line and two new substations.
