Telecommunications

Telecommunications is a particularly relevant asset in electricity companies owing to its influence in the re-establishment of the electricity service, its contribution to the quality with which this service is provided, and its use for managing and monitoring the various distribution and generation installations.

Telecommunications is also used for centralising operations in control offices, and also for automating many processes and their management and remote supervision. Moreover, it is used to set up the WAN(1) and LAN(2) networks that support the corporate IT networks.

IBERDROLA's telecommunications infrastructure consists of different networks: backbone (fibre optic and PLC(3)), transmission (PDH(4), SDH(5), DWDM(6)), data-switching (MPLS), voice-switching (switchboards) and radio.

To operate, supervise, monitor and manage this telecommunications infrastructure, IBERDROLA has a Communications Network Management Centre (C.G.R.) that operates 24 hours a day, 365 days a year.

The telecommunications infrastructure owned by IBERDROLA is not only used to provide services to the Group's businesses. Usage and rental agreements have also been reached with various telecommunications suppliers and customers.

Fibre optic network

The main advantage of the fibre-optic network is that it enables large volumes of information to be transmitted at high speed.
Taking advantage of the electricity distribution network infrastructure, IBERDROLA has deployed more than 17,103.1 km of fibre optic cable, with a sustainable growth of around 3.99% a year.
