Project name:“Energicentralen” 

Project managers: Charles Winther Hansen, Klaus E. Christensen and Mette Lorentzen.

  • Energicentralen and the Aquifer Thermal Energy Storage are an equal partnership between Bjerringbro Varmeværk (the local district heating plant) and Grundfos.
  • Both parties have invested 17 million DKK / 2.3 million EUR in the system and  share expenses and profit equally.
  • The plant serves a double purpose: Grundfos reduces its energy consumption for the cooling of machinery in the factory, and Bjerringbro Varmeværk (district heating plant) - and its consumers - benefit from surplus energy produced by cooling compressors and heat pumps.
  • The annual reduction in CO2 emission is calculated at 3,000 tons.
  • The project creates a great cohesion in the local society because it ties the company to the local society.
