i-DE increases resilience and reliability of its facilities in Castilla y León with a new mobile substation

  • This equipment, placed on a semi-trailer for road transport of over 14 m. long, 4.20 m. high and 2.50 m. wide with a total weight of 47,200 kg., is installed quickly, reducing the time required to restore the supply in the event of an incident or maintenance work

  • It also guarantees supply during the dismantling phases prior to the substations’ renovation

i-DE, Iberdrola España’s distribution company, has a new state-of-the-art mobile substation in Castilla y León that will increase resilience and reliability of its facilities in the region.

This equipment, placed on a semi-trailer for road transport of over 14 metres long, 4.20 metres high and 2.50 metres wide with a total weight of 47,200 kg, is installed quickly and safely, reducing the time required to restore supply in the event of an incident or maintenance work. It also guarantees supply during the dismantling phases prior to the substations’ renovation.

"This innovative team is key to continue offering our Castilian and Leonese customers the best quality in terms of service," says Óscar Villanueva, i-DE's Director in Castilla y León.

The new 12.5 megavolt ampere (MVA) mobile substation − one of the most versatile of its kind and custom-built for Iberdrola España's distribution company − consists of a 45 kilovolt (kV) system and a medium voltage system, consisting of a shielded switchgear with SF6 insulation.

"This engineering solution also required the skills of i-DE’s team to support during the equipment installation and commissioning," says Villanueva.

i-DE closed last year reaching the best year-end value in its history in terms of service quality

i-DE closed 2023 in Castilla y León reaching the best year-end value in its history in terms of service quality. Iberdrola España's distribution company manages more than 50,000 kilometres of power lines and has 15,754 transformer stations in service and 249 substations.

In recent years i-DE has undertaken an "ambitious" plan to digitalise its electricity grids, converting its more than 1.5 million meters in the region and the infrastructure that supports them into smart meters, incorporating remote management, supervision and automation capabilities.

The digitisation of the electricity distribution grid will provide more information to implement additional energy efficiency and sustainability measures, in a way that is committed to ambitious and urgent climate action. The deployment of smart grids makes it possible to respond to new models of grid use and offer a better service to citizens.
