Merger for self-consumption
Use self-generated electricity
The Federal Government’s Energy Strategy 2050 supports decentralized electricity generation and consumption at the place of production. If several electricity consumers want to use locally generated electricity together, this can be done by joining forces for self-consumption (ZEV). As part of the revision of the law, it will also be possible in the future to use self-consumption across districts with so-called local electricity communities (LEG) and virtual ZEV.
Meter configurations in association for self-consumption
The following graphics explain visually what the electricity flows and the positioning of the electricity meters look like with and without ZEVs.

Establishment association for self-consumption
Several electricity consumers can join together to form a common consumer and use the electricity produced locally together. To do this, they form a community of interests and appoint a ZEV representative. The ZEV representative organizes the billing of the energy drawn from the public power grid and the energy produced locally to the consumers within the ZEV. All of the services required for this can optionally be obtained from IBC
Details of the procedure
In order for a ZEV to be founded, a number of points must be taken into account.
01
Before the merger, the parties involved (owners, tenants, etc.) must agree on the merger. If necessary, the contractual relationships must be adjusted.
02
The property owners appoint a ZEV representative.
03
The property owners apply to IBC to establish the ZEV three months before the start of operations using the form below, and state in it which participants are waiving the basic supply (regulated tariff) and joining the ZEV community.
ZEV application
Billing within the ZEV
- The ZEV representative determines the billing model within the ZEV; if necessary, he can commission a billing service provider to do this. For example, you can use the billing service provided by IBC Energie Wasser Chur.
- The ZEV representative commissions an electrician and ensures that the electrical installation and the measuring arrangement in the house correspond to the new situation.
Responsibility in a ZEV
From the date of commissioning, the ZEV is considered a single customer by IBC. The landowners are responsible for all matters within the ZEV, such as:
- Manage the community and create internal bills for electricity costs yourself or through a billing service provider.
- Ensuring the power supply of the participants within the ZEV.
- Compliance with legal requirements for internal consumption measurements and for the allocation of the corresponding costs.
- Liability towards IBC Energie Wasser Chur for the installation checks within the ZEV.
- Appointment of a ZEV representative who will perform the following tasks:
- He is the sole contact person for IBC for all matters concerning ZEV, in addition to the responsibilities listed above, e.g. with regard to contractual agreements on connection to the distribution network or procurement from the network.
- He shall inform the IBC in writing at least three months in advance, at the end of the month, of any new members joining the community and any changes to its size. The community is jointly and severally liable for the costs incurred by new members joining and leaving the community, as well as for any damage caused by non-registration.
