The Mettlen–Lavorgo powerline, also called the Lukmanier powerline, is the 400 kV three-phase alternating current high voltage electric power transmission line over the Lukmanier Pass in Switzerland, from Mettlen substation (47°6′55″N 8°20′15″E / 47.11528°N 8.33750°E), next Inwil, about 7-kilometre (4.3 mi) south of Hochdorf, to Lavorgo substation (46°26′28″N 8°50′20″E / 46.44111°N 8.83889°E), next Lavorgo, about 5-kilometre (3.1 mi) south of Faido. Trees falling on the line in 2003 caused a major blackout in Italy.
