RTE, France's electricity transmission operator, has chosen to replace sulfur hexafluoride (SF₆)- a greenhouse gas whose global warming potential is about 24,000 times greater than that of CO₂ - across its entire high-voltage network, using GE Vernova's SF₆-free g³ technology, part of GRiDEA solutions to decarbonize the grid. The decision makes RTE the first transmission system operator in the world to do so across its complete range of high-voltage substations.
