France, Paris: GE Vernova’s Grid Solutions business will manufacture, deliver, and commission the world’s first 245 kV SF6-free gas-insulated substation (GIS) for Réseau de Transport d’Electricité (RTE) in France. It will deploy its advanced B105 SF6-free GIS which will support RTE in replacing SF6 with its g3 alternative. g3 allows for about 99% reduction in CO2 equivalent of the gas contribution to global warming compared to SF6.

The project is part of RTE’s goal to reduce the carbon footprint of transmission infrastructure by using alternatives to SF6, while enabling energy transition by connecting low carbon energy. One GIS will prevent the addition of about 20000 tons of CO2 equivalent to its high-voltage grid. The gas-insulated substation will also include Grid Solutions’ SF6-free F35g 145 kV, which already benefits from six years of return on experience.

The 245 kV B105 Dual Gas GIS is co-funded by the EU’s LIFE Program and is a result of Grid Solutions’ research funded by the LIFE21 project named LIFE SF6-free GIS. The three-and-a-half-year project aimed to develop a 245 kV substation that is SF6-free and compatible with both SF6 and g3 gas. The substation can support networks up to 245 kV for onshore and offshore power generation and transmission and energy-intensive industry applications.

“With the launch of our B105g GIS, we are only one step away from completing our SF6-free GIS range allowing transmission system operators in Europe and elsewhere to significantly reduce the carbon footprint of their substations by replacing SF6 with g3 gas mixture as soon as they feel ready to proceed. The SF6-free GIS range up to 420 kV is expected to be completed in 2026 with the 170 kV F35 Dual Gas GIS,” commented Vera Silva, CTO of GE Vernova Electrification.
