DONG AND VATTENFALL TO COOPERATE FOR HORNS REV 3

Cooperation is possible, even if you are competitors. Dong Energy and Vattenfall have initiated a common project to ensure the emergency power supply for DONG Energy’s wind farm, Horns Rev 2, and Vattenfall’s upcoming wind farm Horns Rev 3. Both DONG Energy and Vattenfall Vindkraft A/S now secure their billion DKK investments in the Horns Rev 2 and Horns Rev 3 wind farms in the North Sea with a mutual agreement on supply of emergency power for each other’s wind turbines if their respective export cables to land fail. The small diesel generators in the wind turbines at Horns Rev 3 will ensure the power supply for a few days until Vattenfall knows how long a potential power failure will last. If it seems to last for a longer period, the supply from Horns Rev 2 is switched on and the wind turbines on Horns Rev 3 can be supplied with emergency power until the export cable is back in operation.
Horns Rev 3 will consist of 49 wind turbines with a total capacity of 406.7 MW, which can generate power equivalent to the annual consumption of 425,000 Danish households. The wind farm has been established within an 88 square kilometre area 29–44 kilometres west of Houstrup Strand on Jutland’s west coast. Just like the other two Horns Rev wind farms, Horns Rev 3 will be placed in an optimal wind area. (Source: Dong Energy)
