The software company zevvy AG and Elektrizitätswerk der Stadt Zürich(ewz) are joining forces for electricity billing solutions. In future, ewz will also use the flexible billing platform, which calculates energy flows in multi-party buildings and neighbourhoods, as detailed in a press release. The zevvy software enables the billing of solar power for self-consumption (ZEV), virtual ZEVs (vZEV), tenant electricity and local electricity communities (LEG), as well as heating and water costs and charging stations for electric vehicles. In future, the platform will be used as a white label, i.e. under the ewz logo.
According to the press release, ewz benefits in particular from the software’s integration capability, which can be used with various building technology systems, monitoring platforms, smart home providers and Internet of Things (IoT) solutions. This versatility enables a flexible system architecture for future energy services and reduces lock-in effects. This makes it more difficult to switch to other providers or systems.
“We are delighted that other partners from the zevvy ecosystem are contributing to our success. The software enables work in the client system. For example, dSyde SA supports French-language projects and Prola Services GmbH helps with the initial migration effort,” says Cyrill Burch, CEO of zevvy.
The background to the partnership is the increasing importance of shared solar power and the associated services and technologies. For example, active energy management in solar energy communities and the concept of local energy communities), which will be introduced in January 2026, require new solutions. Ewz wants to use the zevvy software to expand its range of energy billing services for property portfolios.
