Cable fault hits Vattenfall's 300MW Thanet wind farm

United Kingdom (UK)Structural Failure

"Weather-dependent" work is underway to replace a section of the cable ...With the weather being with us we would hope to complete it in February, but there is no guarantee with offshore work." The export cable was installed by now-bankrupt cable-laying company Subocean.


 Vattenfall's 300MW Thanet offshore wind farm in the UK is operating at a reduced output because of a cable problem.

The Swedish utility says there is a fault with one of the two export cables that takes power from the wind farm to the onshore network.

The project is still exporting power to the UK's national grid, but exports are limited once wind speeds reach a certain level, says Vattenfall.

A spokesman for the company refused to quantify the exact level of losses, saying that the information is "confidential".

He adds that repairs are underway following two separate problems with the same cable.

 Vattenfall's 300MW Thanet offshore wind farm in the UK is operating at a reduced output because of a cable problem.

The Swedish utility says there is a fault with one of the two export cables that takes power from the wind farm to the onshore network.

The project is still exporting power to the UK's national grid, but exports are limited once wind speeds reach a certain level, says Vattenfall.

A spokesman for the company refused to quantify the exact level of losses, saying that the information is "confidential".

He adds that repairs are underway following two separate problems with the same cable.

"We completed work on a section of the cable that had been bent at too acute an angle in November. But on energisation, we identified another fault on a different point closer to the substation."

"Weather-dependent" work is underway to replace a section of the cable, but it is difficult to predict when this will be completed, the Vattenfall spokesman adds.

"With the weather being with us we would hope to complete it in February, but there is no guarantee with offshore work."

The export cable was installed by now-bankrupt cable-laying company Subocean.

Thanet uses 100 Vestas 3MW turbines. The wind farm, off the coast of Kent in southeast Engalnd, was completed in October last year.
