Denmark, Copenhagen: GE Renewable Energy’s Grid Solutions business has been awarded a contract from Energinet for 31 SF6-free gas-insulated substation bays.
These bays, to be installed at the Amagerværket (AMV) and Vigerslev Koblingsstation (VIK) substations in Copenhagen, will reinforce this city’s electrical grid to support its steadily increasing population growth and electrification agenda.
Based on its mission to ensure that the Danish energy system and grids are “prepared for a future with 100 % renewable energy”, Energinet selected GE’s industry-leading g³ (pronounced “g”- cubed) gas as a game-changing alternative to SF6—a potent greenhouse gas. GE’s g³ gas has a global warming potential (GWP) of about 99 % less compared to SF6.
The project scope includes the delivery of two ready-to-operate 145 kV F35g double busbar gas-insulated substations using GE’s g³ alternative insulating and switching gas. With 22 bays, AMV will be the largest substation installation using g3 GIS at the 145 kV level to date. The VIK substation will consist of 9 bays.
“Utility operators in Denmark are very aware of their environmental footprint and the impact it has on their communities and the world around them,” said Eric Chaussin, Senior Executive High Voltage Products Division Leader at GE’s Grid Solutions.
A report from the EU Commission concluded that fluoronitrile-based gas mixtures—such as g3 gas—may be the only insulating and switching gas alternative to SF6 when space is a constraint, such as in urban areas. That’s because fluoronitrile-based gas products feature the same compactness and performance as traditional SF6 equipment.
