LEG
Also known as: Lokale Elektrizitätsgemeinschaft, Local electricity community
A LEG (Lokale Elektrizitätsgemeinschaft, local electricity community) has allowed the trading of locally produced electricity across the public grid within a neighbourhood or municipality since 1 January 2026. For electricity flows within the community, participants pay a reduced grid charge. Unlike a ZEV or vZEV, participants may use different grid connection points in the local distribution network; smart meters are mandatory.
The LEG is the third tier of Switzerland’s self-consumption models: a ZEV shares electricity behind one connection point, a vZEV settles across several connections of one ownership, and the LEG opens local electricity trading to entire neighbourhoods across the public grid.
For producers with large rooftop systems, this creates an additional sales channel: surplus electricity that previously went to the grid at a low feed-in tariff can be sold within the community on better terms.
The legal basis comes from the second ordinance package under the Electricity Act. The article Virtual ZEV gives an overview of all models.
