The National Office for Electricity and Drinking Water (ONEE) and Red Electrica Espana (REE) have restored an undersea cable from the 2nd electrical interconnection, after several weeks of work. Indeed, one of the cables for the second link of this interconnection was unavailable since a ship damaged it at the end of 2019, 13 km from the Moroccan coast, indicates the ONEE. After the incident, the control and protection systems ordered the isolation of the 2nd interconnection and an action plan for the repair was launched by the maintenance committee made up of Moroccan and Spanish officials.
According to the Office, “the damage being located at a great depth (490 m), the repair in question required highly qualified expertise and heavy logistics including special vessels dedicated to this kind of operation”. The boss of the Office Abderrahim El Hafidi, moreover inquired about the operationalization of all the installations of the submarine cable terminal station at Ferdioua (near Ksar Sghir) made up of very high voltage 400 kV and the hydraulic system for keeping the cables dielectric oil under pressure.
El Hafidi also went to the large Melloussa substation which interconnects with the national 400 kV transmission network to also inquire about the smooth running of this strategic work for the national electrical system. This substation, which constitutes an important node for the national electric transport, brings together the VHV (Very High Voltage) lines of the electrical interconnection between the two countries, the lines coming from the Tahadart power station as well as the 400 kV lines serving the Oualili substation. Note the interconnection has a transit capacity of 2 x 700 MW.
