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.
The powerline was built in 1948–1949. In 2006, 17 transmission towers between Sisikon and Ingenbohl and in 2008, 28 transmission towers between Arth and Küssnacht am Rigi were replaced.
