The grid reinforcement and expansion comprises 25 existing projects and six new ones, as Swissgrid announced on Wednesday when it published its Grid Strategy 2040.
The company is planning to increase the voltage and power on 400 kilometers of Switzerland's 6700-kilometer-long grid. New lines are planned for 790 kilometers. According to the Federal Council, overhead lines have priority.
Swissgrid is planning 21 new controllable transformers to improve the control of electricity flows. Ten are replacements and eleven are new. The grid currently has 22 of these transformers, which are also important for importing electricity.
Swissgrid also plans to renovate 1300 kilometers of the grid. Two thirds of the lines are more than 60 years old.
