Voith Siemens upgrade to boost 32.2-MW Eglisau to 46.9-MW

Kraftwerke Eglisau-Glattfelden AG (KEG) has awarded a contract to Voith Siemens Hydro Power Generation to supply electro-mechanical equipment to boost the capacity of the 32.2-MW Eglisau hydropower plant on Switzerland’s Rhine River.

KEG, a subsidiary of Nordostschweizeriwsche Kraftwerke AG, commissioned Voith Siemens Kraftwerktechnik to deliver seven 6.7-MW Kaplan turbines, generators, governors, and complete control package, totaling 46.9 MW. The units replace seven 4.6-MW Francis units that began operation between 1915 and 1921.

Voith Siemens said using Kaplans instead of Francis turbines increases the flow rate from 385 cms to 500 cms, increasing annual performance about a third to 314.5 GWh from 246 GWh.
