Swissgrid was commissioned to connect the Nant de Drance pumped storage power plant to the Swiss extra-high-voltage grid. This task has been complete since 1 April Construction of the kV line connecting the Nant de Drance power plant to the electricity grid began in It took almost two years of work before the extra-high-voltage cables installed in the 2. This technological feat was made possible thanks to the specific geological conditions present at this exact location in the Rhone plain.
Mission accomplished for Swissgrid: up to now connected by a provisional line, the Nant de Drance pumped storage power plant, one of the most powerful in Europe with a storage capacity of 20 million kWh, is now definitively connected to the electricity transmission grid. Hydropower plays a major role in the energy revolution. One of these projects is the kV line Chamoson — Chippis which will be commissioned in fall The extra-high-voltage line connecting the Nant de Drance pumped storage power plant to the electricity transmission grid consists of three substations and three kV line sections as follows:.
