Work on this substation began in the last quarter of 2021 by Iberdrola, as planned after the agreement promoted by the City Council of Logroño and the company itself; an agreement to bury the Cascajos substation in the same location where it currently stands. It is estimated that it can be completed in early 2024.

“The work continues to meet its deadlines and phases. We are now in the phase where these excavations are being undertaken which will allow the guide walls to be installed, provide space to bury the station and from there build the equipment and continue moving forward in a sub -station scheduled to open in 2024,” said Pablo Hermoso de Mendoza.

The substation, recalled the mayor, was one of the three objectives of the area “which is achieved, together with the works in Vara de Rey and the bus station” and, in this sense, he announced that the bus station It will be open, if no incident occurs, in October 2023.

The location of the Cascajos electrical substation was another unresolved issue in Logroño for over a decade. Thanks to the agreement signed in July last year between Iberdrola and the town hall of Logroño, it was possible to start the action of burying the substation in the same place where it is currently located. The action will cost 5,895,533 euros excluding VAT. Iberdrola will participate in the costs of carrying out this installation with 1,500,000 euros plus VAT, so the net amount that the Town Hall of Logroño will contribute will be 4,395,533 euros.

The works are complex, are carried out by Iberdrola and are divided into five parts. The first three have already been completed and in this fourth phase work on the new substation has already begun, which could end, if this programming continues, at the beginning of 2024. The fifth phase corresponds to the dismantling or removal of the temporary station substation. Iberdrola cedes the land to the Town Hall of Logroño free of charge after completion of the work (part for road use and part for free public space).

After various studies, it was decided to keep the Cascajos electrical substation at its current location. This is a complete underground project, the equipment is below the level of Miguel Delibes Street, and only the access buildings and the chimneys will be visible. The integration of industrial buildings and infrastructures in cities is not only convenient but also necessary to maintain the quality of services required by urban activity.

The study of enclosure alternatives was carried out by Iñaki Ábalos and Renata Sentkiewicz. The study of alternatives includes a careful architectural design that will surround these facilities in a new way and contribute to Logroño continuing to improve aesthetically and functionally, perfecting the development of the Cascajos neighborhood.

“Cascajos” distribution transformer station
The “Cascajos” distribution transformer station was installed in 1990 in what was still the industrial zone of Cascajos to meet the increase in demand that could no longer be covered by the Varea STR and the El Arco STR.

Currently, it assumes a very important part of the Center-South sector of the city with notable energy demands in permanent increase. For this reason, the current situation, at the physical center of demand, represents the best location because there are practically no losses. Other advantages are:

• Increased personal safety following the application of the new regulations. Being a substation composed of shielded systems, the electric field is confined to the shields or enclosures of the components, so there will be no external influences.

• Reduction of the environmental impact by reducing the emission of noise, vibrations or electric and magnetic fields.

• Improvement of the quality of the city’s supply by integrating the latest technological developments.

• Reduction of the impact on other services such as water, gas or telecommunications.

• A reduction in the occupied area of ​​approximately 50%, which contributes to greater aesthetic integration into the environment, freeing up the public space and land needed to complete the Miguel Delibes road.
