Excess heat benefiting the citizens of Padborg

900x416 template (2)
Sustainable solutions enabling the supply of heat to local communities form the basis of the collaboration between Padborg Fjernvarmeværk and Arla’s local dairy in Kruså. The objective of the collaboration is to transform excess heat into domestic heating. This holistic approach to resources underpins the target of supplying 100% CO2-neutral heating to local citizens and businesses by 2030.
Padborg Fjernvarme maintains a razor-sharp focus on the green transition when developing sources of supply for local district heating. The most recent initiative is a three kilometre-long pipeline network and container that enables the district heating plant to tap excess heat from Arla’s dairy in Kruså.


The excess heat was previously emitted into Flensborg Fjord but is now being transformed into heating for the citizens of Padborg. At the same time, the temperature of the water still emitted into the bay has been lowered from 20 to 5 degrees Celsius.


The gain from transforming the excess heat has been calculated at 6,000 MWh annually. This means that some 18,000 MWh of the total annual power consumption by Padborg’s citizens of 30,000 MWh will be green heating. In 2019, one in three of the plant’s consumers received CO2-neutral heating, so the management of the district heating plant is confident they canreach 100% CO2-neutral heating by 2030.


We have a clearly defined green agenda and a wish to meet the government’s climate goals to the benefit of citizens and businesses in our local community. Consequently, our strategy for new sources of supply is to look for locally “anchored” potential, and this arrangement to use Arla’s excess heat means we have taken a major leap forward.”
