Five wind farms in Galicia have environmental green light: the General Directorate of Quality and Environmental Assessment has issued a favorable environmental impact declaration (EID) for the projects Agromaces, Ventoburgo, Sistesas, Xestiloi and Agratina, with an initial joint capacity of 290.99 MW. The resolution, dated October 20, 2026 and published in the BOE on November 5, is a key milestone in renewable energy processing in Galicia, but it is not an unconditional approval.
The public participation process resulted in substantial modifications that developers must internalize before advancing to the construction phase. The merger of two parks, the elimination of wind turbine positions and the requirements on evacuation infrastructure are the most relevant changes affecting the project timeline and design.
What does this regulation establish?
The resolution issues the favorable EID for the five wind farms, but with structural changes compared to the original project. The most relevant data for developers are:
| Wind farm | Initial capacity (MW) | Changes after public participation |
|---|---|---|
| Agromaces | 60.67 | Merged with Agratina; result: 1 park with 9 wind turbines |
| Ventoburgo | 59.85 | No merger; subject to specific protective measures |
| Sistesas | 55.92 | No merger; subject to specific protective measures |
| Xestiloi | 58.31 | No merger; subject to specific protective measures |
| Agratina | 56.24 | Merged with Agromaces; result: 1 park with 9 wind turbines |
Regarding evacuation infrastructure, the resolution establishes a specific scheme:
- 30 kV underground lines for internal evacuation of the parks.
- 220 kV lines for connection to the Castrelo REE substation, located in Ourense.
Execution is conditioned on compliance with specific protective measures established in the resolution itself, aimed at reducing cumulative impacts and protecting the natural and cultural heritage of the affected municipalities. The elimination of numerous wind turbine positions responds precisely to these requirements.
Economic and operational impact
For Wind group developers, this favorable EID is the essential prior step to advance in administrative and construction authorization. However, the imposed changes have direct consequences on the project:
- Reduction in effective installed capacity: the merger of Agratina and Agromaces into a single park with only 9 wind turbines implies a reduction compared to the original configuration. Developers must recalculate estimated production and return on investment.
- Redesign of evacuation infrastructure: burying the 30 kV lines and connecting at 220 kV to Castrelo (REE) entails additional civil works costs compared to aerial solutions.
- Extension of timeline: the need to adapt the project to protective measures before starting works may delay the start of the construction phase.
- Opportunity for the Galician renewable sector: the approval of almost 291 MW in a single administrative act reinforces Galicia's position as a priority territory for wind development in Spain.
Who does it affect?
- Wind group developers: the five developer companies must adapt their projects to the EID conditions before requesting construction authorization.
- Municipalities of Lugo, Pontevedra and Ourense: the town halls of the affected municipal areas must prepare for work license procedures and management of local impacts.
- Red Eléctrica de España (REE): the Castrelo substation in Ourense will receive evacuation from the five parks at 220 kV, which may require adaptations to the grid infrastructure.
- Engineering and construction companies: the project redesign and line burial generate contracting opportunities in the sector.
- Renewable energy sector: the resolution sets a precedent on how public participation can substantially modify wind projects in Galicia.
Practical example
A developer that had planned to develop the Agromaces park (60.67 MW) as an independent project must now assume its merger with Agratina (56.24 MW) into a single park with 9 wind turbines. This means that the joint project, which originally totaled 116.91 MW between both parks, is resized in number of machines. The developer must review the network access contract with REE for Castrelo, recalculate the annual energy produced with the new configuration of 9 wind turbines and update the economic feasibility study before requesting administrative construction authorization.
Additionally, the obligation to bury the 30 kV lines implies a civil works surcharge that must be incorporated into the project budget before closing financing.
What should companies do now?
- Review the project design in light of the EID conditions: identify which wind turbine positions have been eliminated and update technical plans and reports.
- Update the economic feasibility study incorporating the new configuration of merged parks (Agratina + Agromaces = 9 wind turbines) and the costs of burying 30 kV lines.
- Coordinate with REE access to the Castrelo substation (Ourense) at 220 kV to confirm available evacuation capacity and connection timelines.
- Review the specific protective measures imposed in the resolution and incorporate them into the technical conditions specifications for the construction phase.
- Initiate administrative construction authorization procedures before the competent bodies of the three affected provinces (Lugo, Pontevedra and Ourense), providing the favorable EID as an enabling document.
- Inform affected municipalities about the new project design and expected timelines to minimize conflicts in the local licensing phase.
Frequently asked questions
What is a favorable environmental impact declaration and what does it allow you to do?
The favorable EID is the pronouncement of the General Directorate of Quality and Environmental Assessment that certifies that the project is environmentally viable, provided that the established conditions are met. In this case, it enables Wind group developers to advance toward administrative construction authorization of the five wind farms, but it does not authorize the start of works by itself.
Why were the Agratina and Agromaces parks merged?
The merger resulted from the public participation process. To reduce cumulative impacts on the natural and cultural heritage of the affected municipalities, the resolution imposed the merger of both parks into a single one with 9 wind turbines, eliminating numerous positions compared to the original project. Agromaces had 60.67 MW and Agratina 56.24 MW in the initial configuration.
What is the evacuation infrastructure approved for these parks?
Evacuation is carried out through 30 kV underground lines for internal park connection, and 220 kV lines for evacuation to the Castrelo REE substation, located in Ourense. This configuration was established as a condition in the EID resolution itself.
In which Galician provinces are these wind farms located?
The five wind farms (Agromaces, Ventoburgo, Sistesas, Xestiloi and Agratina) are distributed among the provinces of Lugo, Pontevedra and Ourense. The REE evacuation substation is in Castrelo, in the province of Ourense.
When does this resolution enter into force and what timeline do developers have?
The resolution was published in the BOE on November 5, 2026 and entered into force that same day. No specific deadline is established in the available data for developers to submit the adapted project, but the EID is the starting point for initiating administrative construction authorization procedures before the competent bodies.
