Elia has completed repairs to a cable connecting the Rentel offshore wind farm to the mainland.
Repair work was completed four months on from the failure of the wire.
The fault was located just below the Rentel transformer platform.
A new section of cable, approximately 400 metres long, was attached to the structure and connected to the existing wire under the seabed.
The four connected wind farms were still able to generate electricity throughout the repair work, because they are part of the meshed offshore high-voltage grid, via Elia’s MOG or offshore power hub.
Their power output was capped slightly during periods of very high winds to prevent the operational export cables from being overloaded.
Despite this, another offshore and onshore wind energy production record was broken in the first few months of this year.
The repair work was very technically complex and challenging due to the location of the fault and the weather conditions, stated Elia.
The cause of the fault is still being investigated.
