DIGITALISATION OF THE DANISH DISTRICT HEATING SECTOR
CASE CATALOGUE 2023
“THE SUPPLY TEMPERATURE HAS BEEN LOWERED. WE CAN USE ANALYSES TO DETECT WHETHER A SERVICE PIPELINE IS IN POOR CONDITION, OR WHETHER THE FAILURE IS DUE TO A FAULT ON THE CUSTOMER'S INSTALLATION. WE’VE ALSO FOUND BRANCH PIPES THAT WEREN’T INCLUDED IN OUR REGISTRATIONS.”

pump installation. The monitoring will help the company as- sess the improvement potential at the company’s pumping stations by measuring whether the pumps are functioning optimally and thereby most energy-efficiently. In collabora- tion with LOGSTOR, Brønderslev can now digitally monitor a local supply area using copper wires embedded in the insulation material around the pipes. The aim is to demon-
strate how the tool can be used to detect leaks early and thus prevent serious damage.
Brønderslev Fjernvarme has also greatly benefitted from collaborating with the universities that participated in HEAT 4.0. The operating data from the system was used in several research projects and publications.

Challenge With a top-of-the-line production facility, Brønderslev Fjernvarme wanted to optimise how it utilises the facility by collecting and using data from customers, the distribution system and weather forecasts. The district heating company located at the northern top of Jutland, was part of the research and innovation project HEAT 4.0, with the aim to optimise existing systems and establish data-sharing across suppliers. The project ran from 2018-2021 and received funding from Innovation Fund Denmark. Solution The project focused on optimising existing systems, imple- menting new systems and establishing seamless data-shar- ing between suppliers using HEAT 4.0’s cloud solution from Center Denmark.
temperature have been lowered. Furthermore, a program is being developed to use meter data from a few selected me- ters to generate heat demand forecasts for a certain section. Currently, the data stems from measurement points in the district heating network. Results So far, great success has been achieved using just 15 me- ters. Together with EMD, Brønderslev has developed an ap- plication to provide hourly rolling forecasts for all its 12 production units. The forecast is compared with the existing planning tools to document the optimisation of costs in connection with heat production. The application will be implemented soon. In collaboration with Kamstrup and based on remotely read data from the settlement meters produced by Diehl Metering, Brønderslev Fjernvarme has been able to analyse whether there is a fault in a service pipes or in the custom- er’s installation. This helps identify where a line needs to be fixed, and helps detect unknown branch pipes at the consumer’s household.
