A gas-insulated substation is a high-voltage substation that utilizes sulfur hexafluoride gas as the insulating medium at moderate pressure for phase-to-phase and phase-to-ground insulation. The primary conducting structures are enclosed within a sealed environment.
The main voltages in the gas-insulated substation market are categorized as medium voltage, high voltage, and extra high voltage. Medium voltage typically refers to voltages above 1 kV and commonly extends up to and including 52 kV. These substations are installed both indoors and outdoors and serve various applications, including power transmission, power distribution, and power generation. They are utilized by different end-users, including power utilities, the industrial sector, and the commercial and residential sectors.
Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.
The sharp rise in U.S. tariffs and the ensuing trade tensions in spring 2025 are having a notable impact on the utilities sector, particularly across power generation, grid modernization, and renewable energy initiatives. Increased duties on imported equipment such as turbines, transformers, solar panels, and battery storage systems are driving up both capital and operational expenses for utility companies, prompting many to delay projects or pass higher costs on to consumers through increased energy rates. The water and waste management sectors are similarly affected, as tariffs inflate the cost of essential machinery, piping, and treatment technologies. Moreover, retaliatory tariffs from key trading partners have disrupted the supply of critical raw materials-such as rare earth elements vital for clean energy technologies-posing further challenges to the shift toward sustainable energy. In response, the sector is increasingly focusing on domestic procurement, digital transformation, and efficiency-enhancing innovations to control rising costs while safeguarding energy reliability and meeting regulatory demands.
The gas-insulated substation market research report is one of a series of new reports from The Business Research Company that provides gas-insulated substation market statistics, including global market size, regional shares, competitors with a gas-insulated substation market share, detailed gas-insulated substation market segments, market trends and opportunities, and any further data you may need to thrive in the gas-insulated substation industry. This gas-insulated substation market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The gas-insulated substation market size has grown strongly in recent years. It will grow from $24.45 billion in 2024 to $26.81 billion in 2025 at a compound annual growth rate (CAGR) of 9.7%. The growth in the historic period can be attributed to development of high voltage transmission systems, space constraints and urbanization, demand for reliable power infrastructure, environmental considerations, increased grid complexity.
The gas-insulated substation market size is expected to see rapid growth in the next few years. It will grow to $40.04 billion in 2029 at a compound annual growth rate (CAGR) of 10.5%. The growth in the forecast period can be attributed to regulatory support and environmental concerns, demand for compact and high-efficiency substations, focus on grid resilience and reliability, increasing grid modernization initiatives, transition towards renewable energy. Major trends in the forecast period include product innovations, technological advancements, rising focus on grid reliability, integration of renewable energy, technological advancements in GIS.
The forecast of 10.5% growth over the next five years reflects a modest reduction of 0.3% from the previous estimate for this market. This reduction is primarily due to the impact of tariffs between the US and other countries. Supply constraints and cost escalations triggered by tariffs on SF6 gas handling systems and high-voltage switchgear components, mostly imported from Germany and China, may delay substation upgrades and urban grid deployments. The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.
The rising demand for clean energy is anticipated to drive the growth of the gas-insulated substation market. Clean energy refers to electricity generated from renewable, zero-emission sources that do not pollute the atmosphere during use, as well as energy saved through power efficiency measures. For instance, the 245 kV voltage level is crucial for European high-voltage grid solutions, with SF6-free gas-insulated substations at this voltage being essential for decarbonizing the high-voltage grid. In 2023, a report from the U.S. Energy Information Administration (EIA) noted that utility-scale electricity generation from hydropower in the U.S. reached 240 billion kWh, accounting for 5.7% of the total energy share. Therefore, the increasing demand for clean energy is propelling the growth of the gas-insulated substation market.
The increasing trend of urbanization is anticipated to drive the growth of the gas-insulated substation market. Urbanization refers to the process of city expansion and the movement of more people into urban areas. As cities become more densely populated, the demand for compact, low-maintenance power infrastructure grows, leading to a rise in the use of gas-insulated substations. For example, in April 2022, the World Economic Forum, a Switzerland-based independent international organization, reported that over 4.3 billion people, or 55% of the global population, resided in urban areas, with projections suggesting this figure could reach 80% by 2050. Therefore, rising urbanization is fueling the growth of the gas-insulated substation market.
The gas-insulated substation market is witnessing a key trend in product innovation, with major companies dedicated to developing advanced solutions. Toshiba, a Japan-based electronics company, exemplifies this trend with the launch of the 72kV GIS. This innovative product serves as a replacement for equipment at TEPCO PG's Fuchu Substation and integrates circuit breakers, transmission system switches, lightning arresters, and instrument transformers. The 72kV GIS utilizes a synthetic air blend of nitrogen and oxygen as its insulating medium, offering safety and environmental benefits in case of a leak.
Major companies in the gas-insulated substation market are concentrating on developing gas-insulated substations (GIS) that incorporate g3 technology to lower greenhouse gas emissions and minimize the environmental impact of electrical infrastructure. g3 technology is an innovative gas mixture created as an environmentally friendly alternative to sulfur hexafluoride (SF6), which is commonly used for insulation and switching in GIS. For example, in August 2024, GE Vernova Inc., a US-based company, launched a 245 kV SF6-free gas-insulated substation (GIS). The B105 GIS utilizes g3 gas as a substitute for sulfur hexafluoride (SF6), which has a global warming potential 24,300 times greater than that of CO2 equivalent emissions compared to SF6. This makes it a more eco-friendly option. The installation of this GIS is projected to prevent the release of approximately 20,000 tons of CO2 equivalent into the high-voltage grid, supporting RTE's sustainability objectives.
In January 2023, AcBel Polytech Inc., a company based in Taiwan, acquired ABB's Power Conversion division for $505 million.
