The burying of Iberdrola España's new Cascajos substation in Logroño will be completed by the end of the year

  • The goal of the agreement signed at the end of 2021 between the Logroño City Council and Iberdrola España was to build a new substation, with all its equipment underground and using the latest technologies available in the electricity sector, which will improve the quality of supply, safety and environmental impact 

  • Iberdrola España will be ceding free of charge the plot of land freed up after completion of the works to Logroño City Council (part for road use and part for public open space) 

 

The mayor of Logroño, Conrado Escobar, Iberdrola España's institutional representative in La Rioja, Carlos Sobrino, and the councillor for Energy, Ángel Andrés, visited the works being carried out at the Cascajos substation this morning.

Work on this substation by Iberdrola España began in the last quarter of 2021, as set in the agreement signed by Logroño City Council and the company itself. This agreement aims to bury the Cascajos substation in the same location where it is currently located. Escobar, Sobrino and Andrés checked that the work is proceeding according to plan and it is expected to be completed before the end of the year.

"We are continuing to make progress in the area around the site and completing work that was pending to win this space back for the city of Logroño, all while continuing to provide the necessary energy service to the area", said the mayor. "This is a complex intervention, with a considerable investment and which is the result of close collaboration between Logroño City Council and Iberdrola España, so the necessary steps could be taken in line with the plan and without any significant effects", added Escobar, who emphasised that the completion of these works will also allow the urban development of Calle Miguel Delibes and the surrounding area to be completed.

For his part, Iberdrola España's institutional representative in La Rioja, Carlos Sobrino, has highlighted "the close collaboration between Iberdrola España and Logroño City Council to define the best technical and economic solution for the current substation and the consensus reached for its integration, aesthetically and urbanistically, in the new spaces created from the burying of the railway".

"The new substation, with all the equipment underground and using the latest technologies available in the electricity sector, will improve the quality of supply, safety and environmental impact", added the Iberdrola España rep in La Rioja.

The cost of the project is 5,895,533 euros plus VAT. Iberdrola España is contributing 1,500,000 euros plus VAT to the cost of this installation; Logroño City Council is contributing 4,395,533 euros.

The work carried out by Iberdrola España has been divided into five phases: the first two involve the dismantling of the old installation; the third, the installation and connection of a provisional substation (regional transmission system or RTS); the fourth focuses on building the new structure (the new substation’s two transformers have already been installed and electromechanical work is underway); and the fifth, which will culminate the project with the dismantling of the provisional RTS.

Iberdrola España cedes free of charge the plot of land freed up after completion of the works to Logroño City Council (part for road use and part for public open space).

This is a complete underground project. The equipment is below Miguel Delibes street, and only the access buildings and ventilation columns will be visible. The study of alternatives for the enclosure was carried out by Iñaki Ábalos and Renata Sentkiewicz. The study includes a careful architectural design that will envelop these facilities in a novel way and contribute to Logroño's further aesthetic and functional improvement by perfecting the development of the Cascajos neighbourhood.

Cascajos Distribution Transformer Substation

The Cascajos Distribution Transformer Substation was installed in 1990 in what was still the Cascajos Industrial Estate to meet the increase in demand that could no longer be covered by the Varea and El Arco RTSs.

It currently takes care of a very important part of the city's Centre-South with significant and ever-increasing energy demands. 

The solution proposed for its maintenance at this point by burying it underground aims to increase people's safety, reduce the environmental impact and improve the quality of supply, as well as reducing the surface area occupied by it by 50%
