New District Cooling Plant  

Makes Copenhagen Greener

2013.06.19

Copenhagen’s newly opened district cooling plant will be supplying sustainable air conditioning to Copenhagen City Hall and several large companies nearby. Department stores, museums, hotels, and offices had to cool off their buildings, and server rooms by means of their own electric cooling system, whereas they now have the option of choosing climate-friendly district cooling which means fewer expenses and a cleaner Copenhagen.

This week the main energy supplier in the capital region, HOFOR,  opened a new district cooling plant which uses the naturally cold seawater directly in the cooling production during the winter and electric compressors cooled via sea water in summer months to produce cold air. This green, cool air is used to ensure comfortable temperatures and cool server rooms in the Copenhagen City Hall,  Tivoli Congress Center and many other places.

Lord Mayor of Copenhagen, Frank Jensen, says :

- "District cooling is one of the many green, collective solutions, which helps Copenhagen achieving the goal of becoming the world’s first carbon neutral capital in 2025. In Copenhagen, we are world champions of developing and implementing new and energy-efficient solutions, which are both climate friendly as well as being economical to customers. District cooling is a great example of this, and the major cities in the world need these kinds of innovative solutions in order to lower energy consumption and carbon dioxide emissions. At the same time, the Danish environment solutions and energy solutions have great export potential, which can contribute to create growth and new jobs."

Copenhagen’s first district cooling station was opened three years ago and Lars Therkildsen, CEO at HOFOR, is pleased that HOFOR is now able to offer the commercial customers in Copenhagen an even greater security of supply, he says:

- "We at HOFOR are pleased with the great interest in climate-friendly cooling which large companies are showing us, and we are proud that we are now able to supply even more of the offices, hotels, museums, businesses, and server rooms in Copenhagen with sustainable air-conditioning which, at the same time, comes at a reasonable price. Now that we have two cooling stations, we are able to ensure an even greater security of supply to our current customers, and at the same time, we are already looking into the possibility of extending the district cooling system in Copenhagen in five more areas. If we succeed in implementing all of them, we can save the atmosphere – and the climate accounts of Copenhagen – from up to 30,000 tons of carbon dioxide a year – equivalent to the entire carbon dioxide emissions from a small provincial town." 

Facts about district cooling:
  •  District cooling is the distribution of cold water through a pipe from a cooling plant and to the customer, at which the water, by means of an exchanger, cools the air in the customer’s air-conditioning
  • Customers who choose district cooling can save up to 80 per cent on electricity compared to conventional cooling systems, and reduce their carbon dioxide emissions by up to 70 percent• With two district cooling plants, HOFOR can cool off a total of 1,900,000 square meters in Copenhagen
  • A great part of the year, HOFOR produces zero-carbon cooling, in which cold water from the harbour constitutes a natural and continuous resource• By the end of 2012, HOFOR had invested 312 million Danish kroner in the extension of district cooling
  • It is estimated that the need for cooling, on European levels, will increase with 50 per cent up until 2020
