“WE CAN NOW ANALYSE THE RETURN TEMPERATURE FOR EACH HOUSEHOLD AND HELP CONSUMERS IMPROVE THEIR HEATING HABITS. WE’VE INSTALLED LEAKAGE ALARMS IN CONSUMER METERS, WHICH MEANS WE CAN RESOLVE PROBLEMS BEFORE THEY BECOME SERIOUS.”

can now quickly discover any irregularities such as broken heat exchangers, adverse settings on a meter, or inappro- priate consumer behaviour (e.g. using only a few radiators at maximum settings). By helping consumers become aware of defective instal- lations, for example, and/or inappropriate heating habits, Støvring Kraftvarmeværk has been able to reduce the return temperature.

Thanks to the analysis functions in the IZAR software, the return temperature of each household can be analysed and consumers can receive tailored guidance to help them improve their heating habits. The solution not only provides significant financial savings, it also makes it possible to increase transparency by providing additional services such as access to a web portal or app that lets customers check their daily data, including con- sumption and temperatures.

Støvring Kraftvarmeværk Temperature Optimisation and Localisation Of Faults In Customer Installations CASE 8

Challenge Støvring Kraftvarmeværk wanted to save time and reduce costs by optimising the meter-reading process.

now a thing of the past. Consumption data is automatically transferred to the invoicing system, and the entire process is faster, easier and less prone to errors. High-resolution data and alarm notifications from the SHARKY 775 meters is analysed by IZAR PLUS Portal Meter Data Management software. An alarm notification is sent directly to Støvring Kraftvar- meværk if a pipe bursts or a leak is detected. This makes it possible for the plant to intervene immediately and to prevent additional water losses from causing damage to consumers’ homes. Results Once the project was launched, many leakages were discovered at consumer households. These leakages have now been fixed. Støvring Kraftvarmeværk now provides an additional service with leakage alarms for consumers.

Prior to the project, Støvring Kraftvarmeværk used the ‘post- card’ method to collect consumption data from heat meters.

Furthermore, the district heating plant was losing up to 15 m3 of water every day. The process being used at the time to collect consumption data was a resource-heavy manual process with many places where things could go wrong. The most important requirements were to localise and stop water losses faster, and to optimise supply and return tem- peratures to achieve a more sustainable energy supply and corresponding reductions in CO 2 emissions. Solution Støvring Kraftvarmeværk a.m.b.a now automatically receives remotely read data from SHARKY 775 meters, pro- vided by Diehl Metering. This means manual readings are
