What Is The Driver Of The Gas-Insulated Substation Market?

The increasing demand for clean energy is expected to boost the growth of the gas-insulated substation market. Clean energy refers to electricity that comes from renewable, zero-emission sources that do not pollute the atmosphere while used, in addition to energy saved by way of power efficiency measures. Clean energy consists of 245 kV voltage is a key well-known voltage level for the European high voltage grid answers high voltage merchandise, GE Renewable Energy. Having SF6-loose fuel-insulated substations at 245 kV might be vital to helping the decarbonization of the high-voltage grid. For instance, in 2023, according to a report published by the U.S. Energy Information Administration (EIA), a US-based agency, in 2023, U.S. utility-scale electricity generation from hydropower reached 240 billion kWh, accounting for 5.7% of the total energy share. Thus, the increasing demand for clean energy is driving the growth of the gas-insulated substation industry.

Global Gas-Insulated Substation Market Trends and Insights

Major companies operating in the gas-insulated substation market are focused on developing gas-insulated substations (GIS) that utilize g3 technology to reduce greenhouse gas emissions and minimize the environmental impact of electrical infrastructure. g³ technology refers to an innovative gas mixture developed as an environmentally friendly alternative to sulfur hexafluoride (SF₆), which is commonly used in gas-insulated substations (GIS) for insulation and switching purposes. For instance, 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, an alternative to sulfur hexafluoride (SF6), and has a global warming potential that is 24,300 times higher than that of CO2 equivalent emissions compared to SF6, making it a more environmentally friendly option. The installation of this GIS is expected to prevent the addition of approximately 20,000 tons of CO₂ equivalent to the high-voltage grid, aligning with RTE’s sustainability goals.
