The small Danish city of Vojens is perhaps best known for their accomplished ice hockey team, as well as Vojens Speedway Center, founded by the winner of several world championships, Ole Olsen. Now, the city wins gold in solar heating as well.

SUNRAYS EQUAL COST SAVINGS

“The pleasure of going to work is particularly great when the sun is shining, because I know how the sunrays are saving our customers money,” Arne Holm says. He is the Business Manager at Vojens District Heating Plant, which runs the world’s largest solar heating plant, and the world’s largest thermal pit storage.

It all began when Vojens District Heating Plant decided to cut down their C02 emission and their consumers’ heating bills at the same time. The solution was a largescale solar installation – extremely large-scale. They aimed to cover 50% of the total annual heating with solar heat. In cooperation with advisers they figured out how to reach the goal.
