Grimsel line: underground installation recommended. Monitoring group makes recommendation for the new Innertkirchen – Ulrichen extra-high voltage line
Bern, 19.5.2022 - A recommendation has been made by the monitoring group appointed by the Swiss Federal Office of Energy for the new extra-high voltage Grimsel line: it should be installed underground between Innertkirchen (BE) and Oberwald (VS), while an overhead line should only be planned for the short line section between Oberwald and Ulrichen (VS). The underground cable would be installed either in existing and newly constructed tunnels or in the multifunctional Grimsel railway tunnel.
