26.3 MWth Supply Heat for 1,350 customers in Dronninglund, Denmark
Submitted by Baerbel Epp on September 3, 2014
The output of the 26.3 MWth collector field and the 61,700 m³ seasonal pit heat storage in the Danish town of Dronninglund is said to meet half of the annual heat demand of the plant’s 1,350 customers. The system was inaugurated in May 2014. According to the local district heating supplier Dronninglund Fjernvarme, the total investment costs for the plant amounted to Danish Krone (DKK) 106 million (EUR 14.6 million), of which EUR 6.1 million were invested in the solar installation. The larger part was spent on the district heating pipes, the backup heating system and its building as well as land purchase and consulting. The plant was subsidised by the Danish Energy Technology Development and Demonstration Program, EUDP, which supported the project with DKK 21 million (EUR 2.953 Mio). The payback period is said to be 25 years.
