Stadtwerke Pirna - Fixed Network
From smart metering to smart city in a single solution
Stadtwerke Pirna provides water, district heating, electricity and gas to the city of Pirna (population 40,000) and its region in the east of Germany.
Looking to futureproof its network and capitalize on smart city opportunities, the multi-utility partnered with Diehl Metering. The collaboration has resulted in an AMI network with upgraded water and heat meters, as well as a fully-planned and implemented IoT network with optimal interoperability.

THE CHALLENGE: automating meter readings and unlocking future possibilities
As a forward-looking multi-utility, Stadtwerke Pirna wanted to automate meter reading in its water and district heating networks, and make the most of emerging opportunities in IoT and intelligent monitoring.
Historically, consumers had read their own meters, sending data by postcard or online. This method was time-consuming, onerous for consumers and often resulted in mistakes and incorrect billing. What’s more, the data was only collected once a year – making it impossible for Stadtwerke Pirna to exploit data-based network optimization solutions such as leak detection in the water grid.
The company was therefore looking for a turnkey solution to build an efficient Advanced Metering Infrastructure (AMI) and IoT network, allowing it to automate readouts while benefiting from optimization opportunities and strengthening sustainability. Interoperability was particularly important, as the utility had wider ambitions in the future, including smart city applications.
The solution: a single source for network efficiency and IoT opportunities
Diehl Metering worked with Stadtwerke Pirna to provide an all-in-one solution to address its current network challenges and its future ambitions in IoT.
Through our IoT Network Planning Service, Stadtwerke Pirna was able to define the best-adapted solution for its IoT network. Twelve different antenna sites were identified over an area of 80km2 and, over the next 6 years, the utility’s current meters will be replaced by some 7,200 HYDRUS 2.0 meters for the water network and 1,200 SHARKY 775 heat meters for the district heating network. To address the need for interoperability, the solution relies on IZAR radio technology for current use cases and mioty® for future applications.
Stadtwerke Pirna then made its IoT network a reality by choosing our IoT Network Implementation Service, with Diehl Metering’s team helping to install and commission the on-site antennas and data receivers to maximize their reliability and cost-effectiveness. Data is now collected regularly and automatically forwarded to the Software-as-a-Service solution IZAR PLUS Portal for monitoring, billing and analysis.
The benefits: an optimized and reliable network built for the future
Through the IoT Network Planning Service, Stadtwerke Pirna was able to plan a network that is perfectly aligned with its need for smart metering, network optimization and smart city use cases, as well as its desire for sustainability.
While IZAR radio ensures the reliable transmission of data for its current needs, mioty® opens up a new world of possibilities. This software-based technology will allow the utility to explore smart city uses such as e-car sharing and smart lighting. In addition, the IoT Network Implementation Service has allowed Stadtwerke Pirna to minimize its business risk, since Diehl Metering builds the network and provides a warranty on the complete antenna build.
Finally, the automated meter readouts enabled by the HYDRUS 2.0 and SHARKY 775 meters allow the utility to deliver reliable billing. The overall reading and transfer process is now much faster and more secure, and data can be analyzed in detail using IZAR PLUS Portal. Stadtwerke Pirna now has a powerful tool for optimizing its district heating and water distribution networks, and detecting leaks within hours.
