5 MW off shore farm Tunoe Knob (Denmark)

Denmark's second, and the world's third, off-shore windfarm, at Tunoe Knob off the east coast of Jutland, came into operation in October 1995 (Danish Vindeby off-shore wind farm was the first in the world). Off-shore wind farm technology is interesting for a number of reasons. Partly because there is considerably more wind off-shore and partly because the large wind turbines which are preferred for economic reasons can be difficult to locate on-shore because of the visual impact on the landscape.

The off-shore wind farm at Tunoe Knob consists of 10 Vestas V 39 off-shore turbines, each of 500 kW. Each turbine is a stand-alone, horizontal-axis pitch-regulated up-wind machine. The 39 metre diameter three-bladed rotor is mounted at a hub height of 40.5 metres on a tubular tower.

The production from the wind farm is equivalent to the consumption of 4,000 typical newly-built Danish one-family houses. The same amount of electricity produced from coal-based plant, each year would produce approximately 44 tonnes SO2, 12,500 tonnes CO2, 30 tonnes NOx and 1.8 tonnes of fine dust.

The calculated on-shore noise from the wind turbines at the nearest island of Tunoe is less than a whisper between two people (15 dB(A)). On the mainland it is impossible to distinguish noise from the turbines from the background noise of small waves rolling on-shore or birds singing.
