The Coalsema project has obtained the administrative authorization for the solar park and batteries in Berantevilla

The territorial representative for Industry, Energy Transition, and Sustainability of Álava has granted the prior administrative authorization and the administrative construction authorization to the company Compañía Alavesa de Secado de Madera, S.A. for the Coalsema project promoted in Berantevilla. It is the resolution of October 29, 2026, and was published in BOPV number 218 of November 13, 2026, in the “Other provisions” section, between pages 1/4 and 4/4 (official reference 2026/4839). This recognition opens the way to combine the company’s current cogeneration installation with a photovoltaic solar park and a battery storage system, at the end of the procedure processed in file 01GEY 202500049.

Hybridization of Cogeneration

The purpose of the resolution is not to build a new installation from scratch, but rather the hybridization of the existing cogeneration plant: solar production and storage are added to the existing supply structure. The operation is located entirely at kilometer 5 of Carretera Miranda-Trevino street in Berantevilla, within the plant area of the company Compañía Alavesa de Secado de Madera, S.A., and corresponds to postal code 01211.

The elements composing the infrastructure are divided into three groups:

• The FV Coalsema photovoltaic solar plant, with an installed capacity of 8.32 MW, consisting of 13,284 modules of 715 Wp and a peak power of 9.498 MWp; it has 26 inverters with a nominal power of 320 kW.
• The Bess Coalsema storage plant, 5.6 MW, consisting of 7 containers of 1,629.4 kWh and 28 PCS units with a nominal power of 200 kW.
• Two external transformation centers, 0.8/30 kV, of 10,000 and 7,000 kVA respectively.

The discharge of the generated energy into the grid will be carried out through industrial line 3 of the ST substation in Miranda de Ebro.

Nearly Two Years of Processing

The company submitted the initial permit requests on December 31, 2024. The installation is subject to a simplified environmental assessment, and the environmental documentation was completed on February 17, 2026, following a correction request. On February 18, the request to produce the environmental impact report was completed before the Directorate of Environmental Administration and Circular Economy, within the procedure regulated in section 2 of chapter II of Law 21/2013.

The environmental body’s resolution was published in the BOPV on June 24, 2026, establishing that the project would not be moved to an ordinary environmental impact assessment, provided that the protection and correction measures or controls included in the resolution were adopted. On the other hand, the authorization for grid access and connection was granted by the distributor I-DE Redes Eléctricas Inteligentes, SAU on August 28, 2026, with reference number 9046472820.

The public information process was carried out through the announcement of September 3, 2026, and was published on the 23rd of the month in both the BOPV and issue number 37 of the Official Gazette of the Historical Territory of Álava. No objections were received during this process. Likewise, the affected administrations were not consulted, as the promoters had previously collected and presented specific reports.

Conditions and archaeological heritage

The permit is not unconditional. In addition to the usual clauses —works according to the approved project, and the inclusion and budgeting of the measures ordered in the environmental report within the contract specifications— the resolution sets a deadline: the period for commencement is two years from the date of the resolution, and if the exploitation permit is not requested after this period, the permit may be revoked.

Several reports were received during the processing, two of which place conditions on the execution of the works:

• The report submitted by the Ebro Hydrographic Confederation on June 10, 2026, is favorable, but is linked to obtaining the mandatory permit to carry out works within the scope of public channels.
• The Museums and Archaeology Service of the Provincial Council of Álava notified on October 15, 2026, that an external report is required regarding the damage caused by works already carried out within the perimeter of the Hoyos de Vetrusa archaeological site (ZPA no. 1 of Berantevilla, published in the BOPV on October 3, 1989), that archaeological control must be carried out for the remaining works, and that the Berantevilla City Council may not grant any building permit until there is an archaeological project approved by the Department of Culture and Sports of the Provincial Council of Álava.

Among the affected administrations mentioned were the Berantevilla City Council, URA-Basque Water Agency, and AESA-State Aviation Safety Agency. The resolution notes that the permit granted does not replace municipal, provincial, or other administrative licenses, and does not affect third-party rights or ownership rights. Finally, the resolution does not end the administrative route: an appeal may be filed within one month with the Director of Decarbonization.

The permit was granted on October 29, 2026, by the territorial representative of Álava, Javier Aizpuru Ochoa de Eribe, and was processed according to the procedure established in Article 53 of Law 24/2013 and Decree 48/2020. Adding solar and storage capacity to an industrial facility in Berantevilla leads to an increase in electricity self-consumption and a reduction in dependence on the grid, directly affecting the energy cost of the activity of drying oak and other types of wood.
