Telefónica and Ekkosense: Partnership and digital twins Telefonica’ s work with an AI-based digital twin puts real-time monitoring into the thermal management space, where data centres often find their clearest efficiency gains. The project, developed by Telefónica Germany in collaboration with EkkoSense, uses IoT sensors, advanced analytics and a real-time 3D digital twin to improve the management of critical infrastructure.
The operational value lies in how much more precise the cooling environment becomes. Telefonica says the system allows it to monitor critical equipment in real time, maintain a dynamic thermal and load risk map and receive automated recommendations that help eliminate inefficiencies, extend equipment life and maintain continuity. It also says initial evaluations indicate a 15-20 % reduction in energy consumption for
cooling systems, which has a direct impact on energy OpEx. Rüdiger Kunze, Head of Housing & Site Infrastructure at Telefónica Germany, says:“ Digitalisation makes the data centre visible, automation makes it intelligent. EkkoSense’ s Digital Twin combines both, enabling operators to redefine energy efficiency and proactively guide their infrastructure into the future.”
“ One of the main barriers to data centre optimisation has always been the complexity of traditional tools such as DCIM,” adds EkkoSense CEO Dean Boyle.“ EkkoSense solves this challenge for Telefónica Germany by drawing on new levels of sensing granularity, real-time analytics and 3D visualisation capabilities to create a concise digital twin of the data centre environment. This approach makes immersive real-time optimisation a reality – from the smallest Edge site through to the largest facility.”
