IBC Energie Wasser Chur is a public utility owned by the city of Chur, Switzerland. Within grid level 7, the utility operates approximately 200 transformer stations and 290 distribution cabinets, alongside hundreds of decentralized assets such as PV systems, EV charging stations, and heat pumps.
The energy transition is putting pressure on voltage quality and grid capacity. Grid level 7 lacked transparecy, with decisions often based on assumptions. IBC aimed to implement a secure, cost-effective, and minimally invasive solution to gain near-real-time visibility and improve operational efficiency.
Therefore, with Siemens as a technology partner, the customer wanted to explore solutions that would increase transparency, enable remote monitoring, and support future grid planning.

After a hands-on demonstration and a successful pilot phase, IBC signed a contract with Siemens to begin a full rollout across grid level 7. IBC will equip 200 transformer stations and 290 distribution cabinets with smart, bidirectional SENTRON 3NA6 COM low-voltage high-performance (NH) fuses and SICAM Enhanced Grid Sensor (EGS). The Electrification X IoT suite is a central IoT platform enabling continuous access to grid data, analysis based on key performance indicators, automated alarms, and intuitive operation.  

• Electrification X – Distribution Grid Monitoring (three-year contract)
• Onboarding support
• Hardware: SICAM EGS + SENTRON 3NA6 COM

The implementation is underway and will be carried out progressively over the next two years. Siemens is supporting with an integrated portfolio of hardware, software, and support services.
While IBC leads the hardware deployment and network engineering, Siemens provides the technological backbone and operational support to ensure a reliable and future-ready rollout.
