The Industry and Energy Area of the Government Sub-delegation in Huesca has submitted for public review the addendum to the project for the overhead-underground electric power transmission line at 220 kV with a double circuit between the Mangraners and Peñalba substations. The announcement is published in the Official Gazette of the Province of Huesca number 188, corresponding to Thursday, October 1, 2026, with reference BOPH-2026-188033 and file 4321, and opens a period of 30 business days to submit allegations. The modification affects landowners in Fraga, Candasnos, and Peñalba, in the province of Huesca.

The procedure jointly covers the request for the Environmental Impact Statement, Prior Administrative Authorization, Administrative Construction Authorization, and Declaration, specifically, of Public Utility. The petitioner is Red Eléctrica de España, Sociedad Anónima Unipersonal, with registered office at Paseo del Conde de los Gaitanes 177, La Moraleja, Alcobendas (28109 Madrid).

The competent substantive body to resolve is the General Directorate of Energy Policy and Mines of the Ministry for the Ecological Transition and the Demographic Challenge, which is also the environmental body responsible for issuing the Environmental Impact Statement. The processing complies with Title IX of Law 24/2013, of December 26, on the Electricity Sector, Royal Decree 1955/2000, of December 1, and articles 36 and 37 of Law 21/2013, of December 9, on Environmental Assessment. The addendum responds to allegations from affected individuals and reports issued during the public information process of the original project, whose budget amounted to 35,732,014 euros; the budget for the addendum is estimated at 17,594,846 euros.

Overhead route variants and underground changes

The addendum incorporates specific modifications to the original project. In the underground section of Lleida, splice chambers CE01, CE02, CE03, and CE04 are moved off the roadway to a green area inside the sidewalk, and the trench between CE03 and CE04 is moved to the west sidewalk. Four variants are defined for the overhead route:

• Variant No. 1: between supports T-13 and T-15, with 3 supports and 0.731 km, in Albatàrrec.

Technical characteristics of the installation

The projected line maintains two circuits and a maximum conductor operating temperature of 85 ºC, with a thermal transport capacity of 720 MVA per circuit in summer and 860 MVA in winter. The conductor is of the AL/AW TERN type and the supports are metal lattice towers.

• Total length of the overhead section: 72 km in the addendum, compared to the 71.835 km of the original project.
• Underground section: 484.83 MVA per circuit, 4 splice chambers, and 24 splices.
