Gas Insulated Switchgear Market Report

Global Gas Insulated Switchgear Market Size

The Global Gas Insulated Switchgear Market was worth USD 26.39 billion in 2024 and is anticipated to reach a valuation of USD 56.04 billion by 2033 from USD 28.69 billion in 2025 and is predicted to register a CAGR of 8.73% from 2025 to 2033.

GIS (gas-insulated switchgear) is a high-voltage substation in which important electrical equipment is enclosed in a sealed environment and insulated with sulfur hexafluoride gas (SF6). All of the electrical switching equipment in a GIS is totally enclosed inside modules filled with SF6 gas, including circuit breakers, isolators, earth switches, and busbars. A GIS takes up 10% of the space needed by a traditional substation. It is maintenance-free and takes up relatively little space, making it ideal for substations in tiny spaces. It has a lower risk of failure, which minimizes the frequency of power outages for end users and increases operational reliability and practicality.

Governments are investing in renewable energy-based electricity generation in response to growing environmental concerns. Solar, wind (onshore and offshore), biomass, hydropower, and geothermal power-producing units are all located in rural areas. Companies use HVDC systems to connect such far-flung power-producing sources and reduce transmission losses. HVDC transmission is expected to be efficient for long-distance power transmissions. In new or under-development projects, the combination of renewable power generation sources with HVDC transmission connections is becoming more common. To achieve low losses and fault protection, the entire system must be monitored often and consistently. For optimal operation, HVDC converter stations require high-voltage gas-insulated switchgear. As a result, the market presents an opportunity for gas-insulated switchgear makers.

A vast amount of data is required to plan and construct equipment for a power supply network. Grid expansion projects are delayed due to factors such as government intervention, environmental clearances, and lengthy government approval procedures. These delays lengthen the time it takes to complete grid expansion projects and lengthens the time it takes to buy gas-insulated switchgear. Grid expansion delays make production planning difficult for gas-insulated switchgear manufacturers, as most extra-high voltage switchgear are custom-built to meet the needs of individual customers.

MARKET GROWTH

Factors such as the power industry's transition in terms of upgrading transmission and distribution networks, increased use of renewable energy-based power plants, and others are projected to propel the market forward throughout the forecast period.

MARKET DRIVERS

Renewable energy has become much less expensive than diesel-fired generating, especially in remote places with limited or no infrastructure.

In the industrial and commercial sectors, there has been a considerable increase in demand for distributed generation from renewable energy sources. According to the International Energy Agency (IEA), renewable energy accounted for 25% of global electricity generation in 2018. Renewables contributed to nearly half of the increase in global electricity generation. Gas-insulated switchgear is ideal for renewable energy systems and substations that require high current-carrying and short-circuit capacity. It also comprises the equipment that protects and regulates the electrical system. They fix system flaws, maintaining a steady supply of electricity.

Global concerns about rising carbon emissions, as well as related governmental demands to mitigate these emissions, are driving the growth of the renewable energy sector in many countries. South Korea announced its draft version of the 3rd Energy Basic Plan in 2019, according to the IEA, to increase renewable energy to 35 percent of the country's power mix by 2040. The Ministry of New and Renewable Energy (MNRE) in India also implemented the National Wind–Solar Hybrid Policy in 2018. The goal of the strategy is to create a framework for the development of big grid-connected wind-solar PV hybrid systems in order to make better use of transmission infrastructure and land. The strategy also aims to improve grid stability by lowering the fluctuation of renewable energy generation.

MARKET RESTRAINTS

When compared to air-insulated switchgear with similar features, gas-insulated switchgear can be more expensive.

In terms of initial outlay (CAPEX), manufacturing process, and use of expensive components, such as transformers, switching elements, and a circuit breaker that must be operated inside a dielectric gas-filled enclosure, the procurement cost rises. Land is readily available and inexpensive in North America. Except in places with limited space or in cities with high land costs, air-insulated substations are popular in these countries. Air-insulated switchgear is used by private companies to avoid technical complications and reduce the cost of establishing substations for their facilities.

SEGMENTAL ANALYSIS

By Insulation Insights

During the projected period, the SF6-free segment is expected to develop at the fastest rate.

As an arc-quenching and insulating medium, SF6 has been employed as the standard gas inside high-voltage electrical equipment. The Kyoto Protocol also lists SF6 as a highly potent greenhouse gas, with a global warming potential of 23,500 times that of CO2 and an atmospheric lifespan of roughly 3,200 years. Manufacturers have been looking for a suitable substitute for it in power equipment for a long time as a result of these rules.

By Installation Insights

During the projected period, the outdoor segment is expected to be the largest.

Unlike indoor gas-insulated switchgear, outdoor gas-insulated switchgear is designed to be put in an open environment. The outdoor gas-insulated switchgear is designed to protect all of the apparatus from harsh climatic conditions, such as windstorms or sandstorms, which could result in contamination. Outdoor gas-insulated switchgear is appropriate for outdoor substation design and operates at high voltages in transmission and generation. As the demand for energy rises as a result of urbanization, investments in the transmission and distribution sector are increasing.

By End User Insights

In the next five years, the power distribution utility category is predicted to increase the most. The substantial growth of the power distribution utility industry is due to rapid urbanization in developing economies and government initiatives to expand energy to rural areas.

REGIONAL ANALYSIS

The Asia Pacific GIS market is expected to gain traction due to increased investment in transmission and distribution network expansion, which is driving demand.

For example, IndiGrid, a power infrastructure investment trust (InvIT), reached a deal in February 2019 to purchase Patran Transmission Company Limited (PTCL) from Techno Electric & Engineering Company Limited for USD 33.90 million.

To avoid losses, North America is investing in improving the total performance of electric power generation, transmission, and distribution. Many businesses are purchasing substations to ensure stable and efficient power transmission, which could add significant value to the market.

Because of rising electricity consumption, the upgrade of outdated hydropower plants, and government initiatives to improve grid infrastructure, Europe will dominate the market.

Oil and gas firms, which require a steady power source, are heavily represented across the Middle East and Africa. Oil and gas companies are concentrating their efforts on improving electric power transmission and distribution.
