In the Avedøre Holme district of Copenhagen, not far from Bella Center where the UN Climate Change Conference COP15 takes place 7-18 December, the landscape has changed. The 12 old wind turbines that used to stand there have been taken down, and in their place now stand two of the biggest wind turbines in serial production today – the Siemens 3.6 MW model – each of which has the same capacity as the previous 12. Between them they can supply enough electricity to meet the demands of around 5,000 households.
The sight of these two majestic wind turbines, towering 151.5 metres (497 feet) above the ground, in close proximity to the technologically advanced multi-fuel Avedøre Power Station is likely to become a popular cleantech image with the international media during the UN Climate Change Conference COP15 in Copenhagen from 7-18 December.
One of the two wind turbines, which are operated by leading Danish energy concern DONG Energy, will in the near future be handed over to a cooperative in which 7,000 ordinary citizens have bought shares. DONG Energy has entered a climate agreement concerning the second wind turbine with three Danish companies, which have reserved the CO2 free electricity for their use in the coming years.
The Siemens 3.6 MW wind turbine is (by today's standards) a very large machine more often deployed in offshore wind farms than on land. The wind turbines have a rotor diameter of 120 metres (394 feet), giving a swept area of 11,300 square metres (121,600 square feet). The total weight of the machine is 540 tons.
