Gas Insulated Switchgear (GIS) Market Size & Share Trends, 2033

Gas Insulated Switchgear (GIS) Market Overview

The Gas Insulated Switchgear (GIS) Market size was valued at USD 5800.15 million in 2024 and is expected to reach USD 7950.97 million by 2033, growing at a CAGR of 3.5% from 2025 to 2033.

The gas-insulated switchgear (GIS) market has grown substantially in recent years due to increasing demand for compact, reliable, and high-voltage equipment in power transmission, industrial operations, and renewable energy integration. In 2024, over 92,000 GIS units were installed globally across various voltage categories ranging from 36 kV to above 800 kV. GIS technology uses sulfur hexafluoride (SF₆) or alternative gas mixtures for insulation and arc quenching, offering better space efficiency and lower maintenance compared to air-insulated switchgear. Asia-Pacific accounted for over 47,000 GIS installations in 2023, driven by growing power needs in China, India, and Southeast Asia. Europe followed with more than 19,000 GIS systems, particularly in countries transitioning to decentralized and renewable energy grids. More than 38% of new GIS systems were installed in high-density urban areas where space constraints limit conventional switchgear use. The GIS market continues to benefit from smart grid upgrades, rising investments in high-voltage infrastructure, and the modernization of aging substations. GIS systems now support over 38% of global power transmission networks above 72 kV. Increasing renewable integration, which saw 57,000 MW of wind and solar additions in 2023 alone, is a key factor enhancing GIS installations in transmission and industrial substations.

Key Findings

Top Country/Region: China leads the GIS market with more than 28,000 new GIS units installed in 2024.

Top Segment: 72 kV to 150 kV GIS accounted for over 37% of global GIS volume in 2024.

Gas Insulated Switchgear (GIS) Market Trends

One of the dominant trends in the GIS market is the transition from SF₆-based insulation to eco-friendly gas alternatives. In 2024, over 6,500 GIS units were manufactured with SF₆-free insulation, primarily in Europe and North America. France, Germany, and Japan led adoption of vacuum-interruption and fluoronitrile-based systems as part of their zero-emission grid targets. More than 25 manufacturers are now offering SF₆-free GIS solutions for ratings between 72 kV and 145 kV.

Digital GIS systems equipped with condition monitoring sensors, fiber-optic temperature sensors, and automated diagnostics accounted for more than 21,000 installations globally in 2023. These systems reduce downtime and increase grid resilience. The deployment of SCADA-integrated GIS grew by 17% year-over-year as grid operators moved toward predictive maintenance and real-time fault tracking.

Urbanization is significantly influencing GIS deployment. In 2024, over 41% of GIS systems were installed in urban substations, particularly in metro cities across China, India, Brazil, and the UAE. Compact GIS units offer up to 70% space savings compared to AIS, making them ideal for underground substations and urban power distribution centers.

Renewable energy integration is another critical trend. More than 14,000 GIS systems were installed in solar PV and wind farms in 2023. High-altitude wind farms in India and Chile deployed more than 2,500 GIS units rated up to 145 kV. In offshore wind projects in the North Sea, over 860 GIS modules rated at 245 kV and above were commissioned in 2023.

Hybrid GIS systems—combining GIS for high-voltage and AIS for low-voltage—are increasingly being used in utility substations. Over 5,600 hybrid switchgear installations were completed in 2023 across Europe and Asia-Pacific. This approach reduces costs while preserving footprint efficiency.

Digitization, environmental compliance, and resilience against harsh environments are collectively reshaping GIS procurement strategies. More than 35 countries now mandate environmental reporting for SF₆ emissions, accelerating demand for alternative insulation gases and compact substations.

Gas Insulated Switchgear (GIS) Market Dynamics

DRIVER

Growing demand for reliable and compact transmission systems.

Gas-insulated switchgear systems are essential in high-density urban zones, underground substations, and offshore platforms where space constraints exist. In 2023, over 61,000 GIS installations were executed in metropolitan and industrial hubs worldwide. China alone deployed 18,000 units in high-rise cities such as Beijing, Shanghai, and Shenzhen. GIS systems are also critical in rail electrification and metro projects. In 2023, more than 3,500 GIS modules were installed in rail projects across India, Germany, and Saudi Arabia. Utilities are also upgrading traditional air-insulated stations with GIS to reduce maintenance and extend service life beyond 30 years.

RESTRAINT

High cost of installation and maintenance in comparison to AIS.

Despite its compactness and reliability, GIS is more expensive to procure and install than air-insulated alternatives. The initial cost of a 145 kV GIS bay ranges between 40% and 65% higher than an AIS bay. In 2023, procurement costs for SF₆ and vacuum-interruption GIS systems increased by 12% due to raw material and semiconductor component shortages. GIS systems also require specialized maintenance personnel, and post-installation SF₆ leakage testing can increase operational expenditure by 5–9%. Smaller utilities and municipalities in Latin America and Eastern Europe often delay GIS adoption due to budget constraints.

OPPORTUNITY

Expansion of renewable power generation and grid modernization.

Over 430 GW of renewable capacity additions are expected between 2023 and 2026, creating significant demand for GIS-based substations. In 2023, India added over 17 GW of solar and wind energy, with more than 4,100 GIS installations tied to hybrid grid solutions. Offshore wind farms in the UK and Taiwan incorporated over 1,100 GIS modules for high-voltage interconnection. The U.S. Department of Energy allocated funding for more than 400 grid upgrade projects in 2023, 30% of which incorporated GIS substations to support green energy integration. Utility-scale battery storage installations in California used more than 450 medium-voltage GIS systems to ensure fast switching and grid compliance.

CHALLENGE

Environmental concerns surrounding SF₆ gas and regulatory scrutiny.

Sulfur hexafluoride (SF₆) has a global warming potential of 23,500 times CO₂. In 2023, more than 2.1 million metric tons of SF₆ were used globally across GIS equipment, prompting environmental criticism. Regulatory bodies in the EU and California have introduced phase-out timelines for SF₆ in new switchgear. These measures are affecting OEMs relying on SF₆ as a standard insulation medium. Transitioning to alternatives like fluoronitrile and vacuum interrupters involves redesign, safety testing, and certification, resulting in longer time-to-market and cost escalations. Over 40 GIS projects in 2023 faced delays due to compliance and re-certification challenges linked to gas alternatives.
