1903-1914

• The first steps to construct a DH

system in the centre of Copenhagen was taken just after 1903.

• The customers were CPH City

100 years DH history

Oil crisis in 1973 and 1979

• 1973
• The war in the Middle-East

consumption in Denmark was at that time based on imported oil.

100 years DH history

1979

• The first Heat Supply Act

in the world with focus on:

• Energy supply system

based on different fuels.

• Improving the reliability of

energy and fuel supply.

• Increasing the overall

energy efficiency.
