The large-scale solar heating plant in Braendestrup, Denmark, with a collector area of 8,000 m2 is enlarged to between 16,000 and 18,000 m2.
The plant will also get a seasonal storage, designed as a bore hole storage with 100 holes of 25 meters depth. The storage will also be utilized for storing overflow of wind power by applying a heat pump to transform the electrical power into heat. This is certainly not exergetically sound, but the alternative would be to stop the wind mills.
The renewable fraction will be 50% and the investment will be in the order of 3 mill. Euros. The plant will be designed by the German consultant company Solites, the Danish consultant company PlanEnergi and others. The project is supported by Energy Net Denmark.
