The Dutch-German transmission grid operator TenneT, has awarded ABB an order worth around $1 billion to supply a power link connecting offshore North Sea wind farms to the German mainland grid.
This is the largest power transmission order in ABB's history. It will deploy the world's largest offshore HVDC (high-voltage direct current) system with a rating of over 900 megawatts (MW), keeping electrical losses to less than 1% per converter station, the company said.
The completed link will be capable of supplying more than 1.5 million households with clean wind-generated electricity.
ABB's HVDC Light transmission technology will transport power from the 400 MW Gode Wind II and other wind farms to an offshore HVDC converter station, which will transmit the electricity to the onshore HVDC station at Drpen on the German coast via 135 kilometers of underwater and underground cables. A converter station here will feed electricity into the mainland grid.
"Offshore wind power is emerging as a major source of large-scale renewable energy in Europe to help meet emission targets and lower environmental impact," said Peter Leupp, head of ABBs Power Systems division.
Scheduled to be operational in 2015, this offshore network will help to avoid more than three million tons of carbon dioxide emissions per year by 8% of its electricity requirements. Plans are to double that by 2020.
This is the third offshore wind connection order for ABB in Germany, following the 800 MW Dolwin1 link awarded last year and previously the BorWin1 project.
