ABB says it has won an order from the Dutch-German transmission grid operator, TenneT, to supply an alternating-current (AC) power transmission link connecting Nordergrunde, an offshore wind farm in the North Sea, to the mainland grid in Germany. The order was booked in the first quarter.
The link has a capacity to transmit 111 MW of wind power – enough to serve the needs of more than 100,000 households – once it is commissioned in 2013, ABB says.
As part of the project, ABB will design, engineer, supply and install the 155 kV land and submarine cable system, the onshore and offshore shunt reactors, the onshore 155 kV/220 kV power transformer and the extension of an existing 220 kV substation.
The cable system comprises 3 km by 4 km of single-core AC land cable and 28 km of three core AC submarine cable with integrated fiber-optics.
This is ABB's fourth large order from TenneT for offshore wind connections.
