More than 20 percent of Denmark's energy comes from renewables, with the goal to reach 100 percent in 2050. Denmark is also leading the way in integrating wind power into its electricity system. For the Danish national transmission system operator, Energienet.dk, integration of renewable energy and clean energy supply is at the heart of its vision.
ABB supplied and installed 420 kV (kilovolt) GIS, type ELK-3 C to Energienet.dk's substation in Revsing, which supports a new transmission connection between the substations at Kassø and Tjele. The extremely compact design enabled volume reduction by up to 33 percent and as much as 40 percent less SF6 insulating gas compared to predecessor products. This provided Energienet.dk with an environmental friendly solution in a considerably smaller footprint.
The supplied ELK-3 C have been factory assembled, tested, and shipped as one bay in a container instead of multiple assembly units, which reduced installation and commissioning time at Revsing by up to 40 percent. In addition, GIS technology was chosen as it enabled the substation to be hidden in a building architecture to preserve the aesthetics of the surroundings in Revsing.
Revsing substation helps the new interconnection to double the transmission capacity and improve security of power supply with the help of interconnections linked to grids in Germany and Norway.
