Senior Grid Project Manager, Swissgrid
As the overall project manager, Heinz Krauer is responsible for renovating and constructing new Swissgrid installations.
The installations at the Mühleberg substation had been in operation for up to 60 years and had reached the end of their service life. The former owner, BKW, replaced the old outdoor switching substations with a modern, gas-insulated switching substation. This change in technology significantly reduced the required area by around 29,000 m2 of industrial space, which was converted to natural space and recreational areas. Swissgrid took over the infrastructure project shortly before completion and is building an additional 800 MVA phase-shifting transformer, which is to be completed by the end of 2020. Combining technology and nature in such large construction projects and maintaining a balance between economic and ecological aspects is an exciting challenge. In consultation with all the experts, we managed to find the optimal solution.
