The renovation of the Mühleberg substation included replacing outdoor switching substations with an indoor switching substation. This made it possible to renaturalise an area the size of four football fields, which is to say, convert it back to a habitat for plants and animals.
The construction of the new 30-km-long extra-high voltage line in Goms is making great progress. On the section between Ernen and Ulrichen, electricity has been flowing at 380 kilovolts since October 2019. However, the work is not quite finished yet.
On 20 December, BKW will shut down the Mühleberg nuclear power plant. Forever. The power plant will be switched off and dismantled. This will result in the loss of around 370 megawatts in electricity production in the Bern region.
