Pöyry has been awarded the owner’s surveying contract for the new Linth-Limmern pumped storage hydropower plant by Axpo, Switzerland. The services comprise all geodetic surveying tasks during the construction period lasting until 2015. The value of Pöyry’s assignment is about EUR 2.1 million.



The new Linth-Limmern power station will be installed underground. The project will include building of a new gravity dam, extension of the Tierfehd compensation basin, two new caverns for the turbines and the transformers and two pressure shafts and two underwater tunnels.
