In this article, Hassan Zaheer, Managing Partner & COO, and Saifa Khalid, Senior Analyst at PTR, talk about the growing adoption of SF6-free gas-insulated switchgear (GIS) and whether the industry has reached a tipping point. Over the last five years, manufacturers have significantly advanced SF6-free technologies, closing gaps in their portfolios. Every year, new products with higher voltage and short-circuit ratings are introduced, with the latest being Hitachi Energy’s 550kV SF6-free GIS.  

Regulatory pressure and sustainability goals are driving adoption. In Europe, the revised F-gas regulation bans SF6 in MV switchgear by 2026 and HV switchgear by 2028, is accelerating the transition. The U.S. lacks federal regulations, but states like California and New York are implementing phase-out policies. In Asia, China leads with high adoption rates of SF6-free alternatives, followed by Japan and South Korea. Despite regional variations, the industry is shifting towards SF6-free switchgear due to environmental concerns and the push for net-zero goals. Utilities and developers worldwide are testing SF6-free technologies through pilot projects, setting the stage for full-scale adoption. As major manufacturers move towards SF6-free production, even regions without regulatory mandates, such as the Middle East and South America, may have to follow suit due to supply-side pressures. PTR Inc. continues to monitor these market trends, helping stakeholders navigate the transition to SF6-free switchgear.
