Self-consumption community (ZEV / SCC)
Self-consumption community (ZEV / SCC)
A self-consumption community can consist of a single building or several buildings with the same connection point to the energy supplier.
Within the ZEV, the billing and tariffing of grid electricity and locally produced electricity is handled by the ZEV operators.
In order for this billing to be carried out, the necessary infrastructure and a consistent metering concept for the respective energies are required.

License-required measuring points:
License-required measuring points:
Every measuring point that needs to be recorded is subject to licensing.
Every virtual meter (total production, total consumption) requires a license.
Every M-Bus or LoRa meter register that is to be billed is considered a measuring point (combined heat/cooling meter = 2 licenses) and therefore requires a license, but not the M-Bus gateway itself. Unused meters can be set to inactive.

All billing units to be invoiced must be measured with a meter point. (Apartments, heat pumps, general outflows)
- Telstar 80A
- Telstar CT
- Nimbus 100A (3-point mounting)All production and storage systems must be measured, either together or separately.
Measurements at the house connection/site provide the correct balance total for accurate tariff calculation. House connection measurements are the most important measurement points for dynamic control of consumers within buildings.
Tariffing and billing via smart-me Billing
Depending on the model, tariffs can be calculated using the site/house connection meter and production or, alternatively, using production and virtual total consumption. (+1 virtual total consumption meter)
If several productions are measured (batteries/PV), these must be added together virtually (+1 virtual total meter).
E-Mobility with smart-me and eCarUp
E-Mobility with smart-me and eCarUp
E-mobility is made possible by private, semi-private, or public charging points.
The smart-me Pico 22kW hardware offers the optimal mix of hardware for public and private use in ZEVs. However, there are also other compatible hardware options available with eCarUp.
Billing is carried out, for example, by credit card at a flat rate with eCarUp or directly with smart-me Billing via the apartment bill.
The advanced multilevel load management system controls the Pico charging stations and protects the infrastructure.
Load shedding is handled directly by the hardware or via the multilevel load management system.

Supports existing and new hardware from common suppliers such as Neovac, Techem, GWF, ISTA, Brunata, and more.
Either total generation meters or consumption meters in billing units are measured, or both in the case of Minergie, for example.

The house connection is relevant here for the dynamic control of the house infrastructure, such as heat pumps, charging stations, and solar systems, and for accurate tariffing.
The general and heat pump (heating) meters are measured separately. This ensures that energy costs can be reported individually. Energy costs can either be distributed among the parties on a percentage basis or they can be handed over as a whole to a property management company.
