Understanding self-consumption: ZEV, vZEV & LEG

Self-consumption association

A self-consumption association (ZEV) lets several parties in a building share the solar power from their own roof – and the owner bills that electricity directly to the tenants.

Virtual self-consumption association

The virtual self-consumption association (vZEV) delivers the ZEV without new lines: since 1 January 2025, several buildings with their own connections can be combined computationally via the public grid.

Local electricity community

The local electricity community (LEG) goes beyond the building: since 1 January 2026, producers and consumers within the same municipality can share locally generated electricity with one another via the public grid – at a reduced grid fee.

Tenant electricity billing

Instead of feeding your solar power into the grid for a few centimes, you sell it directly to your tenants – at a fair price that pays off for both sides. SchäferStrom produces the finished bill per flat to go with it.

PV / solar power billing

Your photovoltaic system is generating – now it is about using that power sensibly and billing it correctly. You enter the solar kWh allocated to each flat, SchäferStrom bills them at the solar tariff and turns them into finished invoices.

Billing self-consumption

In a self-consumption community, the correct split is what counts: self-consumed solar power at one price, the remaining grid power at another. SchäferStrom separates the two traceably.
