Danish company Dong Energy has awarded two key contracts to ABB and Siemens for extension work to Walney offshore wind farm in the UK.

The Walney Extension wind park will provide an extra 660 MW on top of Walney wind farm’s existing 367 MW.

Walney wind farm is located 15 kilometers off the coast of Cumbria in the Irish Sea, with its turbines covering an area of approximately 73 square kilometers. The extension site is northwest of the existing installation and will cover an area twice as large at 149 square kilometers.Walney wind farm

Swiss power group ABB has won an order worth around $130m from Dong to supply a high-voltage cable system to the extension.

Claudio Facchin, president of ABB’s power systems division, said that the Walney Extension cable link “will help deliver clean renewable power to more than a million people”.

ABB will design, manufacture, supply and commission the 220 kilovolt (kV) alternating current extruded cable system. The link will include more than 157 kilometers of submarine cable to connect the two wind farm platforms to each other and to shore, as well as 24 kilometers of underground cable for the grid connection.

The extension is being carried out in two phases and earlier this year Dong selected MHI Vestas Offshore Wind’s 8 MW turbine for the first phase. Now it has chosen Siemens to supply its 7 MW wind turbine for the second phase.

Mats Vikholm, senior vice-president for Dong Energy Wind Power, said that the 7 MW turbine “is an upgrade of the 6 MW platform that we are very familiar with and are already installing at both Westermost Rough in the UK and at our Gode Wind 1 and 2 wind farms in Germany. We are certain that this improved and bigger turbine will contribute to driving down the cost of offshore wind power even further.”

Siemens will manufacture parts for the turbines at new production facilities in Hull on England’s east coast.

Vikholm added: “Having manufacturers close to the markets where the supplies are needed is very important to us. This will contribute to driving down the cost of electricity as we’re reducing transport and logistics for these heavy components.”
