ABSTRACT
The project Linthal 2015 upgrades the KLL with an additional high-capacity pumped storage plant. A new underground facility will pump water from lake Limmern 630 m back up to lake Mutt. This will boost KLL’s output from the current 450 kWh to 1,450 kWh, a performance on par with the Leibstadt nuclear power plant or the Cleuson Dixence hydro-power scheme.
