Hagemeyer, a German electronics wholesaler, has commissioned Siemens
to install a cloud-based power monitoring system.

The system will create transparency about energy flow in the Hagemeyer sales and logistics center in Maisach near Munich and will show saving potential at the facility in an effort to achieve long-term improvements in energy efficiency.

The objective is to lower overall energy consumption by up to 15% per year.

Hagemeyer will deploy more than 100 measuring devices of the 7KM PAC series from the Sentron portfolio in Sivacon 8MF1 system cubicles and Alpha 3200 low-voltage power distribution boards and implement the power manager power monitoring software on site.

In addition, it also connects to MindSphere, the open Internet of Things operating
the system from Siemens.

Hagemeyer Deutschland has been a 100% subsidiary of the globally active Rexel Group since 2008. Hagemeyer's implementation of the power monitoring system comes in the wake of the same move by the parent group.

The same power monitoring system with MindSphere connection was previously
successfully implemented at the central warehouse location of the Austrian Rexel
subsidiary Rexel Austria in Weißkirchen.

The implementation has resulted in an annual power saving of around 15% and additional savings in thermal energy at the location.

The objective is to achieve a similar optimisation potential at the Hagemeyer sales and logistics center in Maisach.

"The logistics center in Maisach with an area of more than 40,000 square meters is
one of our most power-intensive facilities. It was the logical choice for a pilot installation. We will familiarise ourselves thoroughly with the system and retrofit other locations in Germany over time on the basis of the results here", explains Ricardo Radowski, Director Business Development at Hagemeyer Deutschland.

Siemens measuring devices will capture and record energy data like current, voltage and output around the clock at the Hagemeyer logistics center. The data will then be integrated directly into the open cloud platform MindSphere via a MindConnect Nano interface.

Hagemeyer utilises a MindSphere app that was programmed specifically for Rexel Group for energy consumption monitoring and evaluation. It analyses actual power consumption values and provides insights into possible optimisation potential. The information is accessible for the Rexel Group only.

Beyond the obvious benefits of systematic power monitoring at the logistics center, the move will open up new business opportunities for Hagemeyer and Rexel Austria. The know-how gained by both companies by allowing Siemens to optimise their energy consumption will now be used in a new business unit, which will offer consulting services to customers from the industry and retail sector looking to improve their own energy efficiency and the implementation of digital, cloud-based technologies.
