Where are we?

1903

100 years DH history 1897 - 1903 • Impossible to find areas for landfills inside the boundaries of the municipality of Frederiksberg. • Construction of a new hospital.

100 years DH history 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 Hall, hospitals and public baths. • Heat production was based on CHP.

100 years DH history 1945 • DH systems were until now primarily established in the larger cities. • The DH companies were municipality-owned.

100 years DH history 1945-1960 • Increasing welfare in the Danish society. • Water-based heating systems are replacing stoves and fireplaces. • New company structure: • Groups of citizens join together and establish consumer co-operatives - inspired by the countryside 75 years ago .

100 years DH history 1945-1960 • What is the driver for the development? • Market • Price difference between gas oil and fuel oil is a kick-off for the expansion of DH in Denmark.

100 years DH history Oil crisis in 1973 and 1979 • 1973 • The war in the Middle-East resulted in increasing oil prices. • Oil supplies to Denmark were reduced. • About 92 % of the energy 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.

VEKS, CTR and HOFOR VEKS • Partnership between 12 municipalities • 350,000 tax-payers • 170,000 end – users • 9,000 TJ (2,500 GWh) DH in Greater Copenhagen • 19 municipalities Køge Bay • 4 integrated systems • 500,000 end – users • 34,500 TJ (9,600 GWh) 40 km
