Aalborg CSP received an order from the Danish district heating plant Egedal Fjernvarme to deliver a 2.6 MWth solar-thermal plant. The system will help reduce the facility's natural gas dependency as well as stabilize energy prices.
Cost-competitive solar heating plant
In recent years, Egedal Fjernvarme has continuously developed it’s operations with the aim of achieving a more sustainable district heating supply. This green transition has included an expansion of the surrounding district heating network as well as a conversion of the individually supplied homes from gas and oil to sustainable heating generated by solar and biomass.
To match the client’s energy requirements at the lowest possible cost, the system from Aalborg CSP is designed as a 3,458 m2 solar plant consisting of highly efficient double-glazed flat solar-thermal collectors.
The solar field consists of 34 rows of flat panels with up to 10 collectors per row. With a capacity of 2.6 MWth, the plant is capable of producing 1,850 MWh heat per year. Combined with the district heating plant's existing biomass boiler and an accumulation tank with a capacity of 2,400 m3, the solar heating plant will provide sustainable heating to 875 customers in Stenløse and Ølstykke.
The system in Egedal consists of the same type of collectors, which Aalborg CSP has successfully supplied to two other Danish district heating plants in Solrød and Smørum. The 13.3 m2 optimized panels from GREENoneTEC have shown the highest performance among all known mass-produced large-scale solar collectors on the international market.
Exceptional operation and high performance
Since Aalborg CSP first introduced the optimized panels on the Danish market, they have set a new standard in terms of cost-competitiveness-/performance level, their 10-year warranty as well as their outstanding documented performance results. All three factors which are of crucial importance to Aalborg CSP.
Construction of the plant commenced in the beginning of spring 2019. The plant was ready to harvest its first sunrays the following summer.
Besides offering a cost competitive solution for heat production, the solar plant also avoids the emission of at least 342 tons of CO2 annually.
