Under the contract, ABB will provide electrical equipment, including transformers, medium-voltage switchgears, and instrumentation and automation systems for the Linth-Limmern station, which will be installed in an underground cavern in the Linthal valley. The project will see water pumped from the lower reservoir (the Limmernsee) to the upper reservoir (the Muttsee), 600m above the station.

The project will help to meet future demand across Switzerland and the first of four generating units is expected to be operational by 2015.

Kraftwerke Linth-Limmern (KLL), a partnership between energy utility Axpo AG and the Swiss canton of Glarus, produces 460MkWh of electricity annually. It manages a complex of hydro power stations and the new facility will boost their total capacity almost four-fold to approximately 1460MW.
