Sustainable Modernization of a Pumped Storage Power Plant

In the Linth-Limmern (CH) power plant, built between 1957 and 1968, four power plant steps use the water infl ows of a 140 km2 area near the source of the Linth. In a multi-year, stepwise project, the company Rittmeyer AG from Baar, Switzerland, has now equipped the high-pressure pumped storage power plant with a completely new control technology. In the fi nal expansion, more than 50 networked process stations ensure safe power plant operation using the Bachmann M1 automation system.
