Global Market Size, Forecast, and Trend Highlights Over 2023-2035

Gas-Insulated Substation Market size is estimated to reach USD 50 billion by the end of 2035, growing at a CAGR of 10% during the forecast period, i.e., 2023-2035. In the year 2022, the industry size of gas-insulated substation was USD 28 billion. The growth of this market can be attributed to the growing demand for compact, low-maintenance power systems by the end of 2035. Gas-insulated substations are generally more reliable and efficient than air-insulated substations. Increasing per-hectare land values is also expected to provide lucrative growth opportunities for the market as the gas-insulated substation consumes space as compared to its equivalents. This substation consumes up to 90% less space than a typical power plant this factor is expected to drive the growth of this market in the forecast period. The main advantage of GIS is that it takes only 10% area of normal substations.

Moreover, rise in the renewable power generation, increasing funds for distribution and transmission infrastructure, the growth in energy demand and restriction of space availability in densely populated urban areas, and also government programs towards electricity accessibility are a few significant factors anticipated to propel the growth of market in the forecast period. The growing investment by the government has also led to the increasing construction of gas-insulated substations globally. ABB was awarded a contract for over USD 100 million in 2021 to provide a substation for the UK's transmission network to incorporate electricity from the Hinkley Point C nuclear power facility. Gas-insulated switchgear will be used in the substation to ensure excellent reliability and efficiency.

Gas-Insulated Substation Sector: Growth Drivers and Challenges

Growth Drivers

  • Higher Safety Provided by Gas-insulated Substations – Gas-insulated substation comes with a variety of advantages. However, one of the most significant advantages and growth driver is that it offers is high safety. As GIS is full of insulating gas such as sulfur hexafluoride, it experiences less explosion as compared to AIS. As a result, there are fewer chances of explosion with GIS and it is safer as compared to AIS. According to a National Renewable Energy Laboratory (NREL) report, GIS systems are more reliable and available than air-insulated substations (AIS). According to the report, GIS systems have a failure rate of 0.1% per year, while AIS systems have a failure rate of 0.6% per year. 
  • Growing Development of Smart Cities – Rising development of smart cities all over the world has promoted the installation of gas-insulated substations owing to their properties being small and efficient. According to a report, the number of smart city projects worldwide grew from 170 in 2013 to 1,000 in 2020. 
  • Rising Demand for Electricity Globally – The demand for electricity all over the world is rising day by day owing to the growing industrial sector, urbanization, and increasing spent by key market players and government on better power supply, in turn, is raising the demand for the gas-insulated substation. The electricity consumption in the United States was 4 trillion kWh in 2019, owing to the growing industrial sector.
  • Rising Focus on Renewable Energy - Governments all around the world are putting more and more effort into lowering their carbon footprint and encouraging the usage of renewable energy sources like wind and solar energy. The requirement for effective transmission and distribution infrastructure has increased as a result, which has increased the necessity for gas-insulated substations. For the wind farm cluster in the Baltic Sea, Siemens Energy was awarded a contract in 2021 to provide two onshore high-voltage direct currents (HVDC) systems. Gas-insulated switchgear technology will be used in the project, which is anticipated to be finished by 2029, to guarantee dependable and effective power transmission.


  • Lack of Awareness Regarding the Modification of Energy Infrastructure in Developing Countries 
  • High Initial Cost – Installing a gas-insulated substation often costs more than installing air-insulated substations (AIS). This is caused in part by the price of the insulating gas as well as the requirement for specific equipment to manage it. As a result, some utilities and project developers might find GIS less appealing.
  • Technical Complexity Associated with GIS

Gas-Insulated Substation Segmentation

Voltage Type (Medium, High, Extra High)

The gas-insulated substation market is segmented and analyzed for demand and supply by voltage type into medium, high, and extra high. Out of these, the high voltage segment is anticipated to hold the largest market share by the end of 2035. The growth of the market can be attributed to its reliability and protection for grid infrastructure. They are majorly used in the case of critical switchyards of large power generation plants. Mostly gas-insulated substations with high voltage transmission grids are indoor type. However, the high voltage segment is driven by the refurbishment of old power transmission infrastructure in developed regions such as Europe and North America. In Canada, the federal government has launched a USD 2.75 billion program to refurbish and modernize the country's aging electricity grid, with a focus on improving the reliability and resiliency of the power supply. This program includes upgrades to transmission and distribution infrastructure, as well as investments in renewable energy sources and energy storage.

Installation (Indoor, Outdoor)
