Switzerland’s largest pumped storage power plant put into operati

After a construction period of approx. 10 years, the new Limmern pumped storage power plant (Switzerland) of “Kraftwerke Linth-Limmern AG” was commissioned with a ceremony at the end of March 2018.

With an output of 1,000 MW, the new power plant is the largest pumped storage power plant in Switzerland and has a height difference of 620 m. The dam, located at 2,470 m above sea level, is the highest dam in Europe.

For Switzerland and the international electricity industry, the power plant is a huge battery that can be used in an environmentally friendly way to stabilize the grid and to ensure peak coverage.

Together with partners, ILF Consulting Engineers had already been entrusted with the design of the underground facilities (powerhouse, transformer cavern, pressure tunnel, surge tank, access tunnel, energy discharge tunnel) in 2009.
