In this article you will read about,

  • how NZR is tapping into new customer segments with its energy management software using IT resources from the Open Telekom Cloud,
  • why NZR's customers are now more satisfied
  • and why cloud technology makes it even easier to save energy and receive subsidies.

Aluminum production, glass manufacturing, basic chemicals – companies in energy-intensive industries such as these are particularly keen to optimize their consumption in times of rising electricity costs. Intelligent energy management and the right recording devices not only help them collect consumption data to find and exploit potential savings – those who use a certified system can also take advantage of the enormous subsidy opportunities offered by the German government, e.g. the peak compensation for energy and electricity tax as well as the reduction of the EEG apportionment.

Our cloud energy management software makes it as easy as possible for our customers. Thanks to the Open Telekom Cloud, they can save energy and money without burdening their own IT departments.

NZR offers such complete systems consisting of electronic meters for all media as well as communication technology and energy management software. The group of six companies covers all services related to energy metering at a total of three locations. Founded in Bad Laer in 1933, the family-owned company now employs around 180 people. As the market leader, NZR offers measurement technology, such as electricity meters, coin meters and energy optimization systems, via electrical wholesalers. Numerous energy suppliers also rely on NZR. The Lower Saxony-based company supports them with metering equipment and services from the areas of repair, calibration, financing, logistics and installation. "For some years now, electronic meters have increasingly been replacing mechanical ones," says Rolf C. Knemeyer, managing partner of NZR. "To take advantage of this development and support our customers in their challenges, we have developed CountVision, a software for intelligent energy management."

Innovative in every detail: In addition to state-of-the-art electricity, gas and water meters, NZR also offers calibration services and energy management software.

Simply digital: Energy management software as a service

Now the company is going one step further: CountVision is no longer installed on-site at the user's premises, but is provided from the cloud. "This makes it extremely easy for our customers. They are now only users and no longer installers, operators or IT administrators," explains Robert Holkenbrink, Head of Development and Product Management at NZR. The on-site IT departments are relieved; the customer can concentrate on his core business. Together with Deutsche Telekom, NZR adapted the specifications of the software to the Open Telekom Cloud and moved the program there. "The changeover was not without problems," reports Holkenbrink. "But in the end, the comprehensive service and personal contact throughout the project led to success."

In spring 2017, NZR launched the cloud-based software at a first reference customer. Six months later, a three-digit number of measuring devices are already networked via it. "We get a lot of positive feedback," says Holkenbrink. "Users are very sensitive when it comes to protecting their data, for example. That's where we can score points with Deutsche Telekom's image and the German locations of the data centers." It's a win-win situation: the energy management software as a service enables companies to save energy and take advantage of tax benefits. NZR, in turn, increases customer satisfaction and sales figures for its product.
