Voith Hydro has received new orders to equip two pumped-storage plants in Austria. The company will supply Vorarlberger Illwerke AG with two pumps and a pump-turbine for the Obervermuntwerk Ⅱ and Rellswerk schemes in Montafon, Vorarlberg. The total value of the order is around €35 million. Within the context of Germany's switch to renewable energy (known as Energiewende), pumped-storage plants are assuming an important role as an efficient, cost-effective and reliable storage technology that has been tried and tested over decades. For Obervermuntwerk Ⅱ, Voith will supply, assemble and commission two 170 MW storage pumps, including the hydraulic torque converter.The plant will be constructed between the Silvretta and Vermunt reservoirs, and will complement the Obervermuntwerk, which has been in operation since 1943.
