The Regional Government declares three power lines in Cáceres to be of public utility

The Regional Government of Extremadura has declared as being of public utility three new 45 kV underground high-voltage lines that will link the Los Arenales, Cáceres, and Cáceres-2 substations, in the municipality of Cáceres. The resolution from the Industrial, Energy and Mining Planning Service, under the Ministry of Industry, Energy, Science and Territory, is published in the Official Gazette of the Province of Cáceres no. 0198, dated October 15, 2026, with reference BOP-2026-4834 and file AT-9671. The declaration enables the occupation of affected assets and rights and opens the way for urgent expropriations.

An underground network of 9.819 kilometers

The project, promoted by I-DE Redes Eléctricas Inteligentes, SAU, located at Periodista Sánchez Asensio street, 1, in Cáceres, was requested on April 16, 2025. It comprises three actions:

• “El Cuartillo” line: link between the Los Arenales substation and the Cáceres substation, with 5.039 km.
• “Las Minas” line: link between the Los Arenales substation and the Cáceres-2 substation, with 4.725 km.
• “San Francisco 1” line: undergrounding of the span between supports 9004 and 9005 of the Cáceres substation, with 0.055 km.

The total conductor length reaches 9.819 km, with an operating voltage of 45 kV, single-circuit underground lines, and HEPRZ1 (AS) 26/45 kV 3x(1x630) mm² and HEPRZ1 26/45 kV 3x(1x630) mm² conductors.

Urban layout and dismantling of the overhead network

The layouts run through public and private plots along the N-630 highway, Hilanderas street in the Las Capellanías Industrial Estate, Río Salor street, Las Villuercas street, the V Centenario Roundabout, and Remedios Buendía street.

The project also includes the undergrounding of fiber optics between support 9000 and the splices with the existing fiber, with 1.060 km of OSGZ1-64/16 rodent-proof underground optical cable, and the dismantling of:

• The section of the 3078-24 “Plasencia” high-voltage overhead line between supports 9000 and 9005, totaling 704 linear meters, along with intermediate supports 9001, 9002, 9003, and 9004.
• The overhead section of the 3078-21 “San Francisco 1” high-voltage overhead line between supports 9004 and 9005, totaling 49 linear meters.

Procedures, conditions, and appeals

The file passed the public information stage with publications in the Official Gazette of Extremadura (August 7, 2025), the Official State Gazette (August 22, 2025), the Official Gazette of the Province of Cáceres (August 5, 2025, with a correction of errors on August 14), the EXTREMADURA newspaper (August 27, 2025), and the notice board of the affected city council (August 11, 2025).

The resolution is based on Law 24/2013, of December 26, on the Electricity Sector, Royal Decree 1955/2000, of December 1, and Decree 221/2012, of November 9. The declaration implies the need for the occupation of assets or acquisition of rights and urgent occupation in accordance with Article 52 of the Compulsory Expropriation Law of December 16, 1954. An administrative appeal (recurso de alzada) may be filed against the resolution, which does not exhaust administrative remedies, before the General Directorate of Industry, Energy and Mines within one month. The document was signed in Cáceres on September 28, 2026, by Juan Francisco Lemus Prieto, head of service.

Impact

The declaration of public utility unlocks the execution of a key infrastructure to reinforce the electricity supply of Cáceres and its industrial surroundings by replacing overhead sections with underground layouts. At the same time, it opens the door to urgent expropriations of the owners of the plots affected by the layout.
