UK's Dogger Bank gets grid-connection deals for 3GW

Das Offshore-Umspannwerk des Windparks Lillgrund in Schweden bündelt die erzeugte Energie und ein 120-MVA-Leistungstransformator transformiert die Spannung von 33 Kilovolt auf eine Übertragungsspannung von 138 Kilovolt, so dass die vom Windpark erzeugte Energie in das schwedische Stromnetz eingespeist werden kann. Neben dem Transformator befindet sich auf der Plattform noch eine Mittelspannungsschaltanlage sowie ein Eigenbedarfstransformator für das Umspannwerk.  The offshore substation of the Lillgrund wind farm in Sweden bundles the power produced and a 120-MVA power transformer transforms the voltage from 33 kilovolts to a transmission voltage of 138 kilovolts so that the power generated by the wind farm can be fed into the Swedish grid. Besides this transformer medium-voltage switchgear and an auxiliary power transformer for the substation are also installed on the platform.

Forewind, the consortium behind the UK’s Dogger Bank – the largest offshore wind development zone in the world – has signed grid-connection agreements for 3GW of capacity, doubling the 3GW it has already nabbed over the past two years.

Forewind – comprising RWE, SSE, Statoil and Statkraft – has now bagged permission from National Grid to link a total of 2GW of capacity into the existing Creyke Beck substation near Cottingham, on the north side of the Humber Estuary in eastern England.

The electricity flowing to that substation will be generated at the first zone – known as Creyke Beck – to be carved out of the massive Dogger Bank area. The Creyke Beck zone will be broken down into two offshore wind farms, each roughly 1.2GW in size.
