New district heating plant means boilers are switched of every summer

1 February 2019

At the end of June, a 5500 MWh solar heating plant will be ready to supply the new Balling-Rødding District Heating Plant. Arcon-Sunmark will build the solar heating plant’s 12,020 m2 solar collector field, supply the 2,500 m3 accumulation tank for storing the solar energy and all of the technical installations. The large-scale solar heating solution is the first stage in the construction of a completely new district heating plant, which includes a boiler installation for biomass and a main building. 

“In the last few years, we have seen a lot of interest in large-scale solar heating that is combined with biomass, and that this solution has been chosen for a completely new district heating plant just confirms this trend. It is a sound and long-lasting investment for the district heating plant and its users, where solar energy will cover 20% of heating needs,” says Thomas Karst, CEO at Arcon-Sunmark.

The new district heating plant is expected to be completed at the end of 2019. Consultancy company NIRAS was responsible for the planning and issuing of tender for the project. The district heating utility company Balling-Rødding Varmeværk was created by a merger of Balling Fjernvarmeværk and Spøttrup Varmeværk in 2018. The new district heating utility company will supply heating to approximately 1,000 users. Both financial and environmental considerations were involved in the choice of solar heating and biomass.

          “Our new district heating plants must have a sustainable profile in the short term and in the long term. By choosing solar
          heating and woodchip, we ensure that we have a stable and cost-effective heating supply, which still takes the environment
          into consideration,” says Kaj Sørensen, Chairman for the Board of Directors at Balling-Rødding Varmeværk.

The solar heating plant at the Balling-Rødding Varmeværk Heating Plant:
• Expected commissioning: June 2019
• Solar capture area: 12,020 m2
• Calculated annual production: 5,500 MWh
• Total number of detached houses whose annual heating requirements will be met: 300 (standard homes 18.1 MWh/year)
• Share of total district heating requirements: 20% (remaining requirements met by biomass heating)
• Storage capacity: 2,500 m3 accumulation tank
• Lifetime: At least 25 years

A complete solar heating field of 12,020 m² will be installed in the spring of 2019.
