DIGITALISATION OF THE DANISH DISTRICT HEATING SECTOR
CASE CATALOGUE 2023
“I THINK THAT HEAT INTELLIGENCE IS A GOOD TOOL. PARTICULAR LY THE COMBINATION OF THE REMOTE READING MODULE READY WITH HEAT INTELLIGENCE PROVIDES A LOT OF INSIGHT – REGARD LESS OF WHETHER I RETRIEVE DATA FOR TROUBLESHOOTING, LEAK DETECTION OR MAINTENANCE.”
CLAUS CHRISTENSEN, OPERATIONS MANAGER, LØKKEN VARMEVÆRK A.M.B.A.
is completely different from the annual snapshot generated by the modelling tool they used to have. Today, Heat Intelli- gence is fully available online 365 days a year, and he can go back, look into a specific development and learn from it. This is a huge gain. After a short period with the new solution, Løkken Fjern- varme has achieved tangible results by optimising the dis- tribution network. Among other things, the district heating company has succeeded in lowering the average pressure from 1.2 to 0.7 bar and to around 1 bar in peak periods. This has resulted in annual savings of € 2.000-3000 for the district heating company. They also use Heat Intelligence to look at behaviour in terms of when the energy has to be accumulated in the network in the mornings. They used to work on the basis of assumptions, but now they have a tool for the task.
Moreover, Løkken Fjernvarme has used Heat Intelligence to achieve a more balanced flow in the two main pipes. Al- though the town has grown, the district heating company set the valves in the network as they always had, but new knowl- edge about the number of cubic metres flowing around the system revealed that some valves had been set incorrectly. After implementing Heat Intelligence, it became clear that the load on the distribution system was extremely uneven. The load distribution used to be 80/20, but now it is 50/50. This has resulted in less wear and stress on the pipelines, and in a significantly lower pressure. Consequently, the company now uses less energy and less money on pumping water in the system.

BENEFITS FOR LØKKEN
Challenge Approximately one in four homes in the supply area around Løkken, Denmark is a holiday home, and this share is increasing. This places high demands on keeping the pipe- lines warm as opposed to all-year houses with a constant baseload. Moreover, rental houses have greater demands for useful metre readings, because it can take a while to discover possible damaged metres. In 2016, Løkken Fjernvarme began to dig up the oldest pipe- lines in the distribution system and found that many of them were in a good condition. The replacement, which was part of a long-term renovation plan, was therefore paused after a couple of years until the data basis for carrying out condi- tion-based renovation was in place. In connection with replacing settlement metres, it was de- cided to move from drive by to an aerial solution, so that data from the metres could be used for analyses, etc. Solution Løkken Fjernvarme has combined new metres from Kam- strup with the visualisation tool Heat Intelligence, which is
Kamstrup's analysis platform that combines facts about the pipelines in the network with data from the remotely read metres. This provides a good basis for optimising the district heating network. The solution was implemented in less than one year to support the use of a motivation tariff and to ensure a quick return on the investment. Results Network reading, new readers and new analysis software have contributed to lower pressure in the network, effi- cient leak detection and optimised renovation of pipelines, because the district heating company now has the right decision basis. The annual software licence is quickly paid for by the opti- misations and savings made because the district heating company uses Heat Intelligence. Previously 5 percent of the operator's time was spent on meter reading.
