Eólica Santiz I opens 45-day public comment period for 49 MW hybrid project

The Industry and Energy Area Department of the Government Sub-delegation in Salamanca has opened for public consultation the request for an environmental impact statement (DIA) and prior administrative authorization (AAP) for the Santiz I wind module, with an installed capacity of 49 MW, and its evacuation infrastructure, intended to be hybridized with the Solaria-Santiz I plant. The announcement is published in the Official Gazette of the Province of Zamora No. 133, dated November 13, 2026, in section I (State Administration), pages 2 to 5, with the official reference R-202602456. Interested parties have 45 business days from the day following publication to submit allegations.

The file is processed under number PFot-ALM-118-EOL and its location covers the municipal boundaries of Mayalde and Peñausende, in the province of Zamora, and Valdelosa, in the province of Salamanca. The authority to authorize the project corresponds to the General Directorate of Energy Policy and Mines of the Ministry for the Ecological Transition and the Demographic Challenge, while the environmental impact statement must be formulated by the General Directorate of Environmental Quality and Assessment, as the project is subject to an ordinary environmental assessment.

The procedure complies with the following regulations:

• Article 36 of Law 21/2013, of December 9, on environmental assessment.
• Article 53 of Law 24/2013, of December 26, on the Electricity Sector.
• Articles 124 and 125 of Royal Decree 1955/2000, of December 1, on the authorization of electrical energy installations.
• Article 19 of Royal Decree-Law 7/2026, of March 20, regarding the reinforcement of public participation in large generation and storage installations.

The promoter is Planta FV100, S.L., with NIF B88241245 and address for notification purposes at calle de la Princesa, 2, fourth floor, 28008 Madrid. The material execution budget for the installation amounts to 36,117,667.79 euros and the request is based on the preliminary project “Hybridization of Santiz I Wind Farm (49 MW)”, dated May 27, 2026, and endorsed under number 202602073 by the Official College of Industrial Engineers of Madrid.

Seven wind turbines with a 135-meter hub height

The projected wind module consists of seven machines of 7 MW each, with the following characteristics:

• Seven wind turbines of 7 MW each, totaling the declared 49 MW.
• Hub height of 135 meters and rotor diameter of 175 meters.
• Transformation ratio of 0.69/30 kV, with transformation centers located inside the tower of each wind turbine.
• Liquid filled type transformation centers, with a unit power of 7.77 MVA.
• One self-supporting anemometric tower of 135 meters, in addition to access roads and auxiliary facilities.
• Seven positions (ST_01 to ST_07) in the district of Mayalde, at altitudes between 901 and 922 meters.

The energy from each machine will be evacuated via 30 kV underground lines to the sectioning center called “Ampliación del centro de seccionamiento Santiz I 30 kV”. Each circuit will collect the production of one, two, or three wind turbines, using RHZ1-OL 18/30 kV 1x630 K Al H25 type cable.

Hybridization with photovoltaics and batteries

The wind module will be integrated into the Solaria-Santiz I hybrid plant, consisting of a photovoltaic module of 49.989 MW and a battery storage module with an installed capacity of 19.993 MW. The three declared modules total 118.982 MW, although the hybrid installation may in no case exceed the power granted at the grid connection point, for which it will have protection and measurement systems to guarantee that limit. The declared purpose is the generation of electrical energy and its evacuation to the transmission grid.

What is excluded from the file and how to appeal

The announcement specifies that the rest of the evacuation infrastructure is not part of this file: the new sectioning center, its connection with the existing “Centro de seccionamiento Santiz I 30 kV”—processed in file PFot-ALM-118 along with the Santiz I storage project—the 30 kV line to the Teso Santo 30/220 kV step-up substation, and the final connection at the Santiz 220 kV substation, owned by Red Eléctrica de España, S.A.U.

The project and the environmental impact study can be consulted at the download link indicated in the announcement and, in person, by prior appointment, at:

• Subdelegación del Gobierno en Salamanca, calle Gran Vía, 31, 37001 Salamanca (telephone 923759065).
• Subdelegación del Gobierno en Zamora, plaza de la Constitución, 1, 49001 Zamora (telephone 980759118).

Both offices are open from 9:00 to 14:00 hours. Allegations may be submitted at any official registry or through the general electronic registry of the General State Administration (rec.redsara.es), addressed to the Government Sub-delegation in Salamanca (code EA0040374) or the Government Sub-delegation in Zamora (code EA0040401), depending on the territorial scope to which they refer. The announcement was signed in Zamora on October 21, 2026, by the head of the Industry and Energy Department, Alfredo Gómez Rodríguez.

The opening of the procedure is the mandatory preliminary step for the project to obtain administrative authorization and the environmental impact statement, such that residents, city councils, and environmental groups from Mayalde and Peñausende now have the only formal window to influence the design of the park and its evacuation before the general Administration resolves.
