The Austrian electrical wholesaler Rexel Austria has placed an order with Siemens to deliver a cloud-based energy monitoring system that will be deployed in its logistics centre in Weisskirchen. The system is expected to reduce annual energy consumption by up to 15 percent, an amount equal to the annual consumption of 40 single-family households. The scope of supply includes 66 communication-capable 7KM PAC 1500 and 7KM PAC 4200 power measuring devices, powermanager energy monitoring software, and connection to MindSphere, the IoT (Internet of Things) operating system from Siemens. A separate app, which is programmed by Siemens developers in Austria in close collaboration with Rexel, analyses current power consumption values and makes the savings potential visible only to Rexel.

Siemens is not given access to the data. In this way, Siemens is helping Rexel efficiently control power usage while also developing a new business model: Rexel is planning to use this technology at another site belonging to the company and, in the future, sell the energy saving solution to other SMEs in all industries.

Industrial plants and commercial buildings such as data centres, office complexes, shopping centres, and logistics centres are an energy system’s largest consumers. Operators are faced with the challenge of using power as efficiently as possible so as to reduce consumption and thus reduce costs. “The EU Energy Efficiency Directive provided the necessary impetus for a proper development,” says Michael
