Higher performance secures Aalborg CSP another order for industrial solar heating plant in Denmark

Date: 27 February 2019

Aalborg CSP, Danish renewable energy specialist and a well-known player on the industrial and district heating market, landed a new order to deliver a 2.6 MWth solar-thermal plant in Denmark. With the system in Egedal, Aalborg CSP continues its series of new projects based on customized solutions with solar and storage supporting a competitive transition to renewable energy.

The sun undoubtedly continues to be a game-changing energy source for the district heating industry in Denmark, where most district heating plants typically switch from natural gas to solar or biomass.

Aalborg CSP received the order from the Danish district heating plant Egedal Fjernvarme A/S to deliver a 2.6 MWth solar heating plant. Renewable energy is a well-known territory for the district heating plant, who joined the ring of renewable heat and hot water producers in 2018 with the installation of a biomass boiler. With the construction of a new solar heating plant, the district heating plant takes yet another step towards a greener and more sustainable energy production.

Cost-competitive solution and best warranty
The 3,458 m2 solar field will – when constructed – consist 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 already 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.

“Aalborg CSP presented us with the best price per delivered MWth as well as an attractive warranty agreement, providing us with a 10-year warranty on the solar collectors. These two factors combined made us choose Aalborg CSP as our partner on this project. We look forward to a great collaboration with Aalborg CSP and aim at obtaining Denmark’s most efficient solar heating plant per m2″says Jørn Arne Nielsen, Managing Director at Egedal Fjernvarme A/S.

With the plant in Egedal, Aalborg CSP continues its series of flat panel projects in Denmark. The system in Egedal will consist of the same type of collectors, which Aalborg CSP has successfully supplied to two other Danish district heating plants. 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.

”We are happy that Egedal, focused on the plant’s actual performance, and the consistency between actual performance and calculations, when choosing their partner for the project, and look forward to helping Egedal Fjernvarme A/S towards their goal of obtaining Denmark’s most efficient solar heating plant per m2 ”, says Jes Donneborg, Executive Vice President at Aalborg CSP.

Construction of the plant will commence in the beginning of spring and the solar energy system is expected to be harvesting its first sunrays this coming summer.
