ZUG, Switzerland, Dec 16, 2025 – Siemens will deploy electrification hardware and software to modernize the low-voltage grid for Swiss utility IBC Energie Wasser Chur (IBC). The project targets the greater Chur area and supports electricity supply for about 40,000 residents.
Grid operators face challenges from distributed energy sources, electricity demand, and voltage requirements. The deployment uses data-driven grid management to address these issues without infrastructure retrofits. The project supports ongoing energy transition efforts while maintaining supply reliability.
Easy Installation into Existing Grid Infrastructure for Maximum Reliability
Over the next two years, IBC will equip 200 transformer stations and 290 distribution cabinets with Sentron 3NA6 COM fuses and Sicam grid sensors. The deployment uses Siemens’ Electrification X IoT suite to collect and analyze grid data and issue automated alerts. The deployment integrates with existing grid infrastructure. The Electrification X IoT suite supports operational monitoring and future grid expansion planning.
“Availability and reliability are paramount for every grid operator. Data-driven transparency enables proactive operation and is essential for the resilient grid of the future. With our technology, we can increase usable grid capacity by up to 30 percent,” said Stephan May, CEO of electrification and automation at Siemens Smart Infrastructure. “We look forward to supporting Chur on its path to climate neutrality by 2040.”
Fit for the Future: Maximum Cybersecurity and Supply Reliability
Electrification X uses certificate-based encryption to secure grid data transmission. Distribution Grid Monitoring software analyzes grid data and issues automated alerts to support grid operations and maintenance planning. Continuous monitoring and automated alerts support grid reliability and maintenance planning.
“The energy transition is causing major bottlenecks in terms of capacity utilization and voltage quality. With Siemens’ technology, we can push ahead with digitalization at grid level 7 in an economical, safe, and reliable way, while keeping future supply power needs firmly in focus,” said Radoje Krstic, protection technology specialist at IBC.
Chur targets to become climate-neutral energy city by 2040, already sourcing about 88% of its electricity from renewables.
