Public information for the 12-megawatt Astiverde Wind wind farm

The Territorial Service of Industry, Commerce, and Economy of Palencia, under the Department of Environment and Energy of the Regional Government of Castilla y León, hereby submits for public information the request for prior administrative authorization and the environmental impact assessment of the «Astiverde Wind» wind farm, 12 MW, and its evacuation infrastructure. The announcement is published in the Official Gazette of Castilla y León (BOCYL) no. 216, dated November 9, 2026, with the reference BOCYL-D-09112026-216-34, and opens a period of thirty business days for the submission of allegations.

The project promoter is Astiverde Wind, S.L., with CIF B-10820611, which is requesting an electrical installation of wind technology under a self-consumption regime with surpluses. The processed file is 34-ATCE-108 and the installation is located within the municipal boundaries of Osornillo (Palencia) and Melgar de Fernamental (Burgos), such that the procedure affects two provinces and the residents and owners of both localities.

The processing is governed by Law 24/2013, of December 26, on the Electricity Sector; Royal Decree 1955/2000, of December 1; Law 21/2013, of December 21, on Environmental Assessment; and Decree 46/2022, of November 24, which regulates the authorization procedures for electrical installations in Castilla y León. The announcement submits three documents for public examination: the basic administrative project of the wind farm and its 30 kV evacuation, the environmental impact study, and an explanatory annex on the integration of the wind farm into the self-consumption complex.

Two 6.25 MW wind turbines limited to 6.0 MW

The project provides for the construction of an electrical energy production installation of wind origin with the following technical characteristics:

• Total nominal power of 12 MW, consisting of 2 wind turbines with a unit nominal power of 6.25 MW, although limited to 6.0 MW each.
• Underground 30 kV evacuation line, consisting of a single circuit, which will conduct the generated energy to the SET CASTOREÑO I.
• Associated civil works: access roads and paths, assembly platforms, foundations, and medium-voltage ducting.

The material execution budget of the project amounts to 5,980,729.94 euros, as stated in the official announcement.

Connection to the shared self-consumption network of Melgar de Fernamental

The park line flows into the SET CASTOREÑO I substation, an infrastructure that is not part of this file and is being processed separately. BOCYL no. 213, dated November 4, 2026, published the public information for that evacuation network promoted by Armonia Green Burgos, S.L., which includes the Castoreño I, Doña Jimena I, Colada I, and El Cid I substations and their connection to the Cotorros 400 kV station, owned by Red Eléctrica de España.

According to those same announcements, the network will allow the electrical supply of the green ammonia plant in the “El Parralejo” industrial estate, in Melgar de Fernamental (file OT-25-14-Armonia Green), and the evacuation of surpluses from the Castoreño, Lindero, and Astiverde wind farms. The Castoreño I substation has two power transformers of 55 MVA and 15 MVA that receive energy from the Castoreño and Astiverde parks, within the same self-consumption scheme.

Thirty business days for allegations and file consultation

Interested parties have a period of thirty business days, counting from the day following the publication of the announcement in the BOCYL, to submit any allegations and observations they deem pertinent. The enabled channels are:

• Electronic consultation of the documentation at the Energy and Mining Portal of Castilla y León (www.energia.jcyl.es).
• In-person consultation at the Territorial Service of Industry, Trade and Economy of Palencia, at Avenida Casado del Alisal, 27, ground floor, by appointment via telephone at 979 715 692.

The announcement was signed in Palencia on October 26, 2026, by the Head of the Territorial Service of Industry, Trade and Economy, José María Casas Inclán.

This procedure is the first hurdle the project must overcome before obtaining the prior administrative authorization and the environmental impact statement; therefore, in the coming weeks, it will be decided whether the park proceeds and under what environmental conditions. For residents of Osornillo and Melgar de Fernamental, as well as for the owners of estates crossed by the 30 kV line, this period is the only formal opportunity to raise objections regarding noise, landscape, avifauna, or land impacts.
