Smart grid security: How redundant OT communication, hardware and UPS solutions from Connect Com and Slat make the energy supply future-proof
The Nidwalden cantonal electricity utility in central Switzerland (EWN) was faced with the challenging task of replacing at least 80% of its electricity meters with smart meters in line with the Swiss Energy Strategy 2025 - a project of considerable scope, as it involved over 20,000 meters. This involved modernizing the entire OT communication infrastructure to meet the high requirements for availability, reliability and future viability.
In times of increasing digital networking, a stable network infrastructure is the basic prerequisite for a reliable energy supply. Any interruption can lead to considerable disruption. The aim was therefore to build a flexible and scalable network that supports future intelligent requirements in the smart grid. A key requirement was to ensure that both the switches and the connected end devices remain continuously supplied even in the event of outages or power fluctuations.
By using a PLC smart meter solution that communicates via Aginode switches with redundant power supply through Slat DC UPSs from the SDC series, the energy supplier found a strong partner for current and future requirements in Connect Com AG Switzerland.
