Competitors, DONG energy and Vattenfall, have joined forces and are cooperating on a project in order to ensure their wind farms have an emergency power supply.
 

According to their press release, ‘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.’
 

Project Manager at Vattenfall, Niels Møller Jensen said, “If the export cable fails, it’s not only critical for the supply of electricity to customers on the mainland. A cable outage is also critical to the wind turbines. All turbines must always have power, especially to keep the blades’ positions correct in relation to the wind direction. Emergency power for the wind turbines normally comes from one single large, centrally located generator on a platform at sea. At Horns Rev 3, we’ve chosen to install a small generator in each of the 49 wind turbines and, as something new in the industry, we’ve made an agreement with DONG Energy that we install an 8km long 33kV cable between Horns Rev 2 and Horns Rev 3, thereby establishing a connection between both wind farms.”
 

DONG Energy Asset Management, Leif Winther said, “We see the cooperation with Vattenfall on the emergency power supply as a good guarantee for both wind farms, which keeps the wind turbines in good condition so that they can start producing again really quickly once the fault is corrected and in addition, it’s a relatively small investment in an emergency power cable if one looks at the total cost of an offshore wind farm.”
