Aalborg CSP received an order from the Danish utility and energy supply company SK Forsyning to deliver a 8 MWth solar heating plant consisting of flat solar-thermal collectors. The system is integrated with SK Forsyning's existing energy infrastructure - including a biomass boiler - for a more flexible energy supply.


Client:       SK Forsyning
Location:    Korsør/Halsskov, Denmark
Status:    Operational
Technology:     Solar-thermal plant
Capacity:    8MWth
Yield:    6,500Mwh heat

The 11,733m2 solar district heating system consists of highly efficient double-glazed flat solar-thermal collectors capable of producing 6,500 MWh heat annually. The system is adapted to fit the district heating plant’s specific temperature set and energy needs and is therefore optimized for high return temperature as well as low average temperature. Likewise, the system is designed to run low-temperature operation enabling the heating plant’s biomass boiler to be used as a temperature booster. 

The solar field is divided in two in order to keep the required distance to a historic burial mound. Aalborg CSP re-designed the entire solar field layout, piping, etc. to keep the necessary distance. As a result, the solar panels are located both north, south and west of the burial mound to make room for the necessary number of panels required for providing the desired amount of energy.
