FMV (Forces Motrices Valaisannes)

FMV is Valais's largest hydroelectric operator and one of Switzerland's critical power producers. Built in 1925, they operate major dams including Grande Dixence (Europe's tallest arch dam) and supply 28% of the country's total hydroelectric capacity. This means FMV electricity is some of Switzerland's cleanest and most reliable.

If you're moving to Valais (Sion, Martigny, or the Alpine communes), FMV is likely your main supplier or part of a shared grid. Because they focus entirely on hydropower, you're getting renewable energy as standard, not a premium add-on. Their customer portal supports online registration and bill management; service outages are rare thanks to their redundant alpine infrastructure.
