Several Danish utilities have already seen great success with this option – which only highlights the importance of having the right tools and data for the job. Having network optimiza- tion in their hands not only enables direct influence and trans- parency but potentially allows for new offerings and business models. Danish Næstved District Heating utilises all three tactics to optimize the demand side of its value chain. In addition to a motivation tariff and energy consultants doing customer visits, the utility developed a rental and maintenance program for heat installations, which they offer to end users as a customer service – with great success. One of the results of their proactive approach is a reduction in the average flow temperature at the entrance of the distri- bution network from 85.3 to 73.7 °C in 2020. In addition, the average return temperature at the end of the distribution net- work was reduced from 47.9 to 43.9 °C, and the heat loss in the distribution network was reduced by 8%. Finally, the utility also reduced the number of bypasses in their network from 131 to 10. Næstved District Heating has seen total annual savings of €350,000. And today, none of the utility’s customers get a flow temperature of more than 75 °C. The resulting lower return temperature also means that significantly fewer cubic meters of water now have to be pumped. From more efficient to better and beyond As the examples from DIN Forsyning and Næstved District Heating clearly show, with the proper insight and tools, the optimization potential on the demand side is enormous. And with more data, we can go so much further. What if we didn’t stop at enabling utility professionals to be more efficient but even better? What if we co-created digital solutions designed to provide some specialist knowledge that
would otherwise be both time and resource-heavy to acquire? What if we fully utilized the value of data from smart energy meters and innovative digital tools? One thing is certain: To future-proof district heating, we’re beyond simply showing our understanding of the challenges utilities face. It’s time for solution providers to present real- world results and proven solutions – ready for implementation.
