Dronninglund1The world’s currently largest solar district heating plant was inaugurated in Dronninglund, Denmark, on 2 May this year. The photo shows Carsten Møller Nielsen, Board Chairman at Dronninglund Fjernvarme, welcoming Rasmus Helveg Petersen, Danish Minister for Climate, Energy and Building (to the left of the speaker). The system consists of 2,982 collectors with a total solar thermal capacity of 26 MWth (37,573 m²) and a 61,700 m³ seasonal pit heat storage and is planned to provide about 15,000 MWh per year. Its output will meet half of the annual heat demand of the plant’s 1,350 customers. According to the local district heating supplier Dronninglund Fjernvarme, the total investment costs for the plant amounted to DKK 106 million (EUR 14.6 million), of which EUR 6.1 million were invested in the solar installation (see the chart below). The plant was subsidised by the Danish Energy Technology Development and Demonstration Program, EUDP, which supported the project with Danish Krone (DKK) 21 million (EUR 2.953 Mio). The payback period is said to be 25 years. Solarthermalworld.org spoke with Søren Elisiussen, CEO at Arcon Solar, which delivered the collectors and the support structure for the solar field, about the plant’s technical specifications.
