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 (), next Inwil, about south of Hochdorf, to Lavorgo substation (), next Lavorgo, about south of Faido. Trees falling on the line in 2003 caused a major blackout in Italy.
On 28 September 2003, during a storm, two trees hit the powerline in Brunnen, causing a major blackout in Italy.
The loss of power affected most of all peninsula; nearly 50 million people remained cut-off for up to 18 hours.
