Gas Insulated Switchgear Market Disruption Analysis

Gas Insulated Switchgear Market Disruption Analysis

Transition Toward SF₆-Free and Eco-Efficient Insulation Technologies Reshaping the Gas Insulated Switchgear Industry

Disruption in the Gas Insulated Switchgear (GIS) market is being caused by the rapid shift away from traditionally used SF₆-insulated switchgear towards SF₆-free insulation systems that help achieve both better insulation efficiency and lower environmental impact. Due to increased environmental legislation and utilities' commitments to decrease their carbon footprint, manufacturers are now developing low global warming potential insulation technologies that allow reducing greenhouse gas emissions to minimal levels while maintaining the same performance level. According to GE Vernova, the company's g³ insulation reduces the Global Warming Potential by more than 99% compared to traditional SF₆ equipment. The company claims that 30 current g³ projects around the world will lower the impact of installed gas volumes by more than 1 million tons of CO₂-equivalent through deployment of over 100 units of 145 kV GIS bays, 9 units of 420 kV GIS bays, more than 5,000 meters of Gas Insulated Lines (GIL), and 14 units of 145 kV Live Tank Circuit Breakers.

Simultaneously, utilities are increasingly focusing on digital substations without SF₆ gases in order to adhere to new environmental legislation and net-zero corporate policies. This is motivating companies to divert their research and development efforts to technologies that ensure clean air, fluoronitrile and fluoroketone insulations. This trend is disrupting the traditional GIS products range, changing procurement requirements and fostering equipment supplier competition.

Expansion of Transmission and Distribution Infrastructure Accelerating Demand for Compact High-Voltage Switchgear

The expansion of transmission and distribution (T&D) infrastructure will remain a key factor that will contribute to the increased demand for Gas Insulated Switchgear (GIS). This is because the need to expand electrical power networks to facilitate electrification, renewables integration, and increased electricity consumption will increase the demand for GIS. The increasing requirement for small and highly reliable substations due to limited space availability in cities will drive the use of GIS in T&D. The International Energy Agency (IEA) has estimated that there have been about 1.5 million kilometers of new transmission lines developed around the world in the last ten years. Nonetheless, the development of the transmission network infrastructure continues to lag behind the growth in the demand for electricity and clean energy. In addition, the IEA identified 1,650 GW of solar and wind projects in advanced stages of development awaiting grid connections.

The continuous growth in the development of high-voltage transmission systems is prompting the implementation of GIS in order to ensure reliability, efficiency, and higher capacity of power transmission. In October 2025, according to Global Times, the Dhabeji Grid Station project in Sindh was on track to become fully operational by December 2025, as the 220/132 kV Gas-Insulated Switchgear (GIS) substation had progressed to 79.77% physically and 87% financially by September 2025. The project worth Rs 6.17 billion includes a GIS grid station along with the construction of a 220 kV transmission line. Design and engineering of the project is 95% completed, while procurement and transportation of equipment is 85% completed. Civil works of the project have been completed to 83.5%, while installation and erection have been completed to 70%. Testing and commissioning of the project has been completed to 18%.

High Dependence on SF₆ Gas Supply and Alternative Insulation Technology Availability

One of the key factors limiting the expansion of the Gas Insulated Switchgear (GIS) market is the ongoing use of sulfur hexafluoride (SF₆), which is still the primary insulating and arc-extinguishing gas in high voltage GIS due to its outstanding dielectric properties. While there has been an effort from manufacturers to push for alternative SF₆-free solutions, commercialization has not taken place yet for extra high voltage applications, thus posing both supply and technology transition difficulties for power companies. The European Commission notes that with the introduction of the F-Gas Regulation (EU) 2024/573 in 2025, there will be more limitations for fluorinated greenhouse gases, thus necessitating the need for manufacturers to move towards low global warming potential insulation solutions while maintaining compliance across all existing and future GIS systems.

Stringent environmental policies aimed at high global warming potential gases are catalyzing the move towards alternatives to SF₆-insulated switchgear technologies. In July 2025, according to The Agility Effect, the European Union's ban on SF₆ is pushing the electricity switchgear industry towards a transition to alternative insulation methods. In accordance with the revised EU F-gas Regulation (2024), SF₆ will be prohibited for use in new medium-voltage switchgear from January 2026 for equipment with 24 kV, and additional phases will expand their application to high-voltage switchgear in the following years. The SF₆, which has a GWP around 24,300 times higher than that of CO₂ over 100 years, is a commonly used insulating medium in GIS because of its excellent arc extinguishing characteristics. The transition towards alternate insulators is proving to be problematic due to the cost involved in finding SF₆-free alternatives, qualification and redesign of equipment, and rising demand for eco-efficient insulators such as vacuum technology and other gases.
