Gas Insulated Substation Market Revenue and Trends 2025 to 2033

The global gas insulated substation market revenue reached USD 33.88 billion in 2025 and is predicted to attain around USD 114.10 billion by 2033 with a CAGR of 16.39%.The growth of the market is driven by the increasing preference among utilities and infrastructure developers worldwide for compact, reliable, and low-maintenance GIS solutions that address rising power reliability demands and land-use constraints.

What are the key factors driving the growth of the gas insulated substation market?

Several interconnected factors are fueling the expansion of this market. Firstly, rapid urbanization and the escalating demand for electricity are key drivers, necessitating substations that occupy less space and offer enhanced reliability. Secondly, as utilities prioritize integrating renewable energy sources and modernizing the grid, they are upgrading older air-insulated substations to gas-insulated substations, which provide superior performance in challenging climates and reduce system maintenance requirements.

Environmental and regulatory considerations also play a crucial role. GIS products minimize the footprint of substations, offering improved safety and insulation. Moreover, the adoption of new gas-insulation technologies and SF6-free alternatives is reducing the impact on greenhouse gas emissions. These combined benefits create a strong growth environment, particularly for deploying robust substations in urban areas with limited space or in emerging regions experiencing growing demand.

Segment Insights:

• By voltage rating, the medium voltage segment dominated the market in 2024 due to its suitability for distribution networks where space efficiency and reliability are critical, particularly in urban and industrial environments.
• By type, the hybrid GIS segment dominated the market in 2024, as it integrates features from various gas-insulated technologies to optimize performance, footprint, and cost.
• By installation type, the indoor segment led the market in 2024, since indoor GIS installations enable substations to be housed within buildings or underground vaults, ensuring better utilization of urban space.
• By application, the power transmission segment dominated the market in 2024, driven by the need for enhanced reliability in high-capacity transmission substations.
• By end-user industry, the power utilities segment dominated the market in 2024, as electricity transmission and distribution utilities are the primary adopters of GIS systems for network upgrades and expansion.

Regional Insights:

Asia Pacific registered dominance in the gas insulated substation market in 2024. The rapid infrastructure development in APAC, coupled with increasing energy demands, urban population growth, and grid modernization efforts, positions it ahead of other regional markets. Additionally, the region is expected to continue its growth trajectory in the upcoming period, as governments in India, China, South Korea, and Southeast Asia making significant investments in new transmission corridors, smart-grid upgrades, and space-efficient substations, all of which are driving the adoption of GIS systems in the region.

Gas Insulated Substation Market Coverage

Recent Development:

• In August 2024, GE Vernova’s Grid Solutions announced it will manufacture, deliver, and commission the world’s first 245 kV SF₆-free gas-insulated substation (GIS) for RTE in France. The project will use GE’s B105 SF₆-free GIS, replacing sulfur hexafluoride (SF₆), a gas with 24,300 times the global warming potential of CO2 with the g³ alternative, cutting CO2-equivalent emissions by about 99%.
