GE to expand SF6-free portfolio
GE Renewable Energy’s Grid Solutions business has announced plans to invest tens of millions of dollars to expand its range of sulfur hexafluoride (SF6)-free high-voltage substation equipment to include all key high-voltage levels by 2025.
GE Renewable Energy’s Grid Solutions business has announced plans to invest tens of millions of dollars to expand its range of sulfur hexafluoride (SF6)-free high-voltage substation equipment to include all key high-voltage levels by 2025.
This is one of Grid Solution’s biggest portfolio investments in years and will support customers in their efforts to reduce greenhouse gas emissions. GE is the leader in SF6-free high-voltage solutions with its Green Gas for Grid, or g3 offering. g3 products feature the same high performance and compact dimensional footprint as traditional products, but with more than a 99 % reduced global warming potential (GWP).
By 2025, GE’s Grid Solutions will offer SF6-free gas-insulated substations up to 420 kV, dead tank and live tank circuit breakers up to 550 kV, as well as instrument transformers up to 420 kV. Currently, GE’s g3 products are type-tested and available for live tank circuit breakers and gas-insulated substations up to 145 kV, gas-insulated lines (GIL) up to 420 kV and instrument transformers up to 245 kV.
Since the first pilot installation of a g3 420-kV GIL by UK’s National Grid in 2017, 15 other leading utilities have chosen GE’s g3 equipment such as Scotland’s SPEN and SSEN, Switzerland’s Axpo, France’s RTE and Germany’s TenneT. By adopting this industry-leading SF6-free technology early on, these 16 utilities have avoided the installation of more than 386,000 tons of CO₂ equivalent on the grid.
