Flat solar-thermal collectors matching the client’s energy needs
Aalborg CSP received an order from the combined heat and power plant Smørum Kraftvarmeværk A.m.b.A. to deliver an 8MWth solar heating plant that will reduce the facility’s natural gas dependency as well as stabilize energy prices.
The 11,312 m2 solar field, which is located in the town of Smørum, consists of flat solar-thermal panels capable of producing 5,568 MWh heat annually. Aalborg CSP’s scope of supply also included delivery of necessary technical installations and 2.2km long piping for energy transmission.
“It was a natural step in our development to switch to a renewable energy source that can also compete with the fluctuating gas prices so we can stabilize the cost of energy production. Flat solar-thermal collectors matched our energy needs the most and we were pleased to receive a cost-competitive solution-package from Aalborg CSP whose diverse solar portfolio and installed global capacity made us chose them as partners for this project” – says Jan Møller, Managing Director at Smørum Kraftvarmeværk A.m.b.A.

Rapid construction and installation
Construction commenced in August 2017 in Smørum and the system was successfully handed over on budget and on time. Altogether 59 rows of flat panels have been installed with up to 20 collectors placed in one row. These 13.3m2 optimized panels have shown the highest performance among all known mass-produced large-scale solar collectors on the international market. The same collector type was also used in another Danish district heating plant (Solrød Fjernvarme) where they performed beyond expectations during Spring and Summer of 2017.
The system has been harvesting the sunrays since Spring 2018. Due to Danish weather records in May, the solar plant was able to produce 40% more energy than anticipated and thereby cover nearly 100% of the city’s hot water and heat demands. This enabled the plant to make a high-performance debut for the official opening, which took place in June 2018. The plant has continued its good results and during the Summer performed above the guaranteed level. Besides offering a cost competitive solution for heat production, the solar plant also prevents the emission of at least 1,100 tons of CO2 annually.
