Power outage in two significant interconnectors: Cobra cable and REMO 2
supply has resumed for two unrelated subsea electricity interconnectors
following repairs to their respective transmission systems. Red Eléctrica
de España (REE) and its Moroccan counterpart Office National De L'electricite
Et De L'eau Potable (ONEE) completed the repair work of reserve cable (number
4) of the submarine cable
between Spain and Morocco (REMO 2)
on 4 September 2020.
On 31 July 2020, a fluid leak was found in the reserve cable (number 4)
the fault was detected in Moroccan waters, 21.6 km off the Spanish
coast and 208 meters deep. A cable laying ship, EDT Hercules carried out
the repair work. Since the damaged cable was out of service, the electricity
supply was not compromised at any time, thanks to its double circuit system.
It was only switched off for a few hours, during the sealing process.
Spain- Morocco interconnection
includes two 400 kV lines, commissioned in 1997 and 2006, consisting seven
cables: three for each circuit, plus one for reserve. All the seven cables
run from Tarifa terminal station at the Spanish end to Fardioua terminal
station at the Moroccan end.
Meanwhile, remedial works on the converter station of Cobra
completed on 12 August 2020 after a fault was detected the day before.
700 MW interconnector
runs between Netherlands and Denmark and was commissioned in 2019.
