Norwegian TSO Statnett has started repairs on the NorNed power cable after it found a fault last month about 300 metres from the Dutch coast.
“Repair time is depending on weather conditions,” the Norwegian grid operator said in a statement, reported Bloomberg. The Oslo-based company owns the cable jointly with Tennet, its Dutch equivalent.
The 700 MW cable, the world’s longest subsea interconnector, closed on April 18. Statnett’s estimated restart date is 27 June, according to the statement.
The statement said: “Repairs on the NorNed cable are proceeding according to plan. The welding of the new cable’s first joint to the original cable was completed this past weekend. Work has now started on the welding of the second joint.
“If weather conditions remain favourable, the work can be completed by the end of the week. The cable will then be laid on the seabed and buried. During the weekend, the cable will be tested. The results of these tests and a definite date on when the cable can be taken back into operation will be published immediately after these tests.”
