Voith has been awarded a contract by
Kraftwerke Oberhasli AG (KWO) to equip the new Grimsel 4 pumped storage power plant in Switzerland. The scope includes the supply and installation of two variable-speed pump turbines, each with a capacity of 70MW, including associated motor generators. The units will increase pumping and generation capacity at the Grimsel site and support the integration of renewable energy by providing flexible storage and grid-stabilisation services.
The project marks the first major new-build contract awarded to Voith by KWO and represents an important milestone in the collaboration between the two companies. A key factor in securing the order was Voith’s competitive offer, as well as a technical concept based on a tested and qualified hydraulic design, which reduces technical risks and supports reliable project execution.
Ueli Gasser, project manager for electromechanical installations at Grimsel 4 at Kraftwerke Oberhasli AG, said: “Grimsel 4 is an important step in further developing our storage capacity and strengthening system flexibility. Voith’s technically convincing solution and the constructive collaboration throughout the tender phase were key factors in our decision. We look forward to continuing the partnership during project execution.”
Aleksandar Glamoclija, key account manager Germany at Voith Hydro, said: “We are proud to support Kraftwerke Oberhasli AG with the Grimsel 4 project and further expand our footprint in Switzerland. The close collaboration throughout the tender phase laid a strong foundation, and we look forward to continuing this partnership during project execution.”
With Grimsel 4, Voith further strengthens its footprint in the Swiss hydropower market and contributes to the expansion of flexible energy storage capacity in the region.
