Partial outage in the electricity supply on Menorca

Red Eléctrica de España restores the electricity supply on the island of Menorca

  • All substations of the transmission grid on the island are back on line and in service at this time.
  • Work continues on the damaged towers of the Dragonera-Ciudadela line.
  • The Special Maintenance Plan has enabled the restoration work on the damaged infrastructures to be carried out in a swift manner.

 

Red Eléctrica de España restored the electricity supply on the island of Menorca at 5:44 pm today after bringing the Dragonera-Mercadal line (15.5 kilometres) back into service. During the next few hours the Company's operators will continue with the rebuilding works of the damaged towers in the Dragonera-Ciudadela line (37.5 kilometres).

Despite the adverse weather conditions on the island and the difficulties posed by the orography of the area affected by rain and wind storms, a team of more than 40 experts has been working round the clock since the partial power outage occurred in order to remove unused materials and undertake power restoration works. The actions undertaken by the Company will be extended until the two high voltage lines that provide the electricity supply are operational once again.

All the programme of planned actions has been carried out more swiftly thanks to the Special Maintenance Plan that was activated in 2018 and that has both the emergency manpower and technical measures required to bolster the security and reliability of the Menorca transmission grid and, if needed, to reduce the time required to restore the supply.

The deployment within the agreed times of the cranes required to complete the work, and the hiring of a helicopter with the capacity to carry heavy loads that carried out inspection and hoisting tasks, together with the prior analysis of possible contingencies, has made it possible to make full use of all available manpower and material resources on the island in record time.

In addition to having available the necessary spare parts to accelerate the restoration works, Red Eléctrica de España has deployed several teams of workers in the field who have been working together in a coordinated manner round the clock in shifts, both for the dismantling of damaged towers and the assembly of towers as well as to conduct the consolidation works in the area. All actions have been carried out while ensuring the utmost safety of all personnel involved.

In order to minimise waiting times for service restoration, Red Eléctrica has collaborated with Endesa so that emergency generators could be deployed in order to temporarily restore the electricity supply via the electricity distribution network.

Lastly, the Company has kept the relevant authorities fully abreast of the situation and work carried out at all times and has coordinated all its work with the public administrations and services involved, not only at the regional and local level, but also with the central government.

In this regard, Red Eléctrica has had the support of the Regional Government of the Balearic Islands, which provided both maritime and air transport to the Company. Similarly, the Military Emergency Unit and the General Directorate of Emergencies and Internal Affairs have coordinated the needs of the municipalities affected.
