Public information on the Subero and Durakogain wind cluster, 9.9 megawatts

The Official Gazette of the Historical Territory of Álava of Friday, November 13, 2026 (no. 131) publishes the announcement of October 27, 2026, from the Director of Decarbonization of the Basque Government, Guillermo Allende Aranguiz, by which the project and the environmental impact study of the “Subero and Durakogain wind farm cluster” (9.9 MW) and its associated infrastructures are submitted for public information, in the municipal terms of Aramaio (Álava) and Eskoriatza (Gipuzkoa). Interested parties and the public have 30 business days from the day following publication to submit allegations.

The procedure is supported by Article 7 of Decree 115/2002, of May 28, which regulates the authorization procedure for wind farms in the Autonomous Community of the Basque Country, and Article 53 of Law 24/2013, of December 26, on the Electricity Sector, in accordance with Law 21/2013, of December 9, on environmental assessment, and Law 10/2021, of December 9, on Environmental Administration of Euskadi. The file number is 01-GE-Y-2025-00018 // 20-GE-Y-2025-00006.

The prior administrative authorization corresponds to the Directorate of Decarbonization of the Department of Industry, Energy Transition and Sustainability of the Basque Government, which jointly processes the public exhibition of the project and the environmental impact study, pursuant to Article 36 of Law 21/2013. The application includes the prior administrative authorization and the environmental impact statement, with the purpose of generating electrical energy through onshore wind renewable technology.

Two 4.95 megawatt wind turbines and a 30 kV line

The promoter is Alerion Spain, SL (CIF B67364885). The technical characteristics declared in the announcement are as follows:

• 2 wind turbines with a unit capacity of 4.95 MW and a hub height of 110 meters, in the municipal term of Aramaio (Álava).
• 1 meteorological tower of 110 meters, also in Aramaio.
• 30 kV high-voltage underground lines from each generator to the switching center, of approximately 3,775 meters and 2,961 meters, through Aramaio (Álava) and Eskoriatza (Gipuzkoa).
• 30 kV switching center in the municipal term of Eskoriatza (Gipuzkoa).
• Evacuation point to the distribution network: an existing support of the 30 kV overhead power line L3051 08 Mondragón-Eskoriatza 1, owned by i-DE, Redes Eléctricas Inteligentes, SAU.
• Material execution budget excluding VAT: 16,886,731.87 euros.
• Total installed capacity of the cluster: 9.9 MW.

Where to consult the file and how to submit allegations

The documentation may be examined at the Territorial Delegation of Álava, at Samaniego Street number 2 in Vitoria-Gasteiz; at the Territorial Delegation of Gipuzkoa, at Easo Street number 10 in San Sebastián; and on the public information website for mining and energy projects at euskadi.eus.

Allegations shall be submitted to either of the two territorial delegations, in physical format at their general registry or through the general electronic registry of the Public Administration of the Autonomous Community of the Basque Country, as well as through the methods provided for in Article 16 of Law 39/2015, of October 1, on the Common Administrative Procedure of Public Administrations. The deadline is 30 business days starting from the day following the publication of the announcement.

The announcement warns that legal entities, entities without legal personality, and other subjects identified in Article 14 of Law 39/2015 are obliged to interact with public administrations by electronic means, therefore their allegations in this process must mandatorily be submitted via that route.

A shared project between Álava and Gipuzkoa

The cluster extends across two historical territories: the generation and the meteorological tower are located in Aramaio, while the sectioning center and part of the evacuation route are located in Eskoriatza. This dual implementation explains why the public information is channeled through the territorial delegations of Álava and Gipuzkoa and why the file is split into two reference numbers.

The joint public exhibition of the project and the environmental impact study is the previous step to the environmental impact statement, the pronouncement that conditions the prior administrative authorization of the installation. Until that process is concluded, the file remains open to observations from neighbors, city councils, and environmental groups in the area.

The announcement arrives in a context of processing new wind farms in the Basque Country under Decree 115/2002 and state regulations of the electricity sector, with the environmental assessment as the central filter of the procedure.

For readers of the region, the publication of November 13 marks the start of the actual participation period: during the next 30 business days, any person may consult the project, review the environmental impact study, and submit allegations that could modify the scope of an installation of 9.9 MW and a budget of 16.9 million euros on the border between Álava and Gipuzkoa.
