Parques Eólicos San Lorenzo, SLU has the green light to build the Solar San Lorenzo B photovoltaic module in Valladolid. The resolution of May 7, 2026 simply corrects material errors detected in the original authorization of April 16, 2026, without touching the essence of the project or the authorized capacity.
What is relevant for landowners and energy sector stakeholders is that the declaration of public utility remains in force, which means that the promoter can initiate procedures for occupation or expropriation of necessary land in the three affected municipalities.
What does this regulation establish?
The Resolution of May 7, 2026 from the Directorate General for Energy Policy and Mines remedies material errors detected in the resolution of April 16, 2026. That original resolution granted Parques Eólicos San Lorenzo, SLU two key authorizations:
- Prior administrative authorization for the Solar San Lorenzo B photovoltaic module.
- Administrative construction authorization for the same module and part of its evacuation infrastructure.
The project consists of the hybridization of the new solar module (39,288 MW) with the existing San Lorenzo B wind farm (39,375 MW), sharing evacuation infrastructure. This solar-wind hybridization model optimizes the use of the grid connection and improves the profitability of the whole.
The corrections introduced by this resolution are of a formal or technical nature (incorrect data in the original resolution) and do not alter any substantial condition of the authorization: neither the capacity, nor the municipalities, nor the promoter, nor the declaration of public utility.
| Element | Detail |
|---|---|
| Type of correction | Formal material errors or incorrect technical data |
| Does the substance of the authorization change? | No |
| Resolution being corrected | Resolution of April 16, 2026 |
| Issuing body | Directorate General for Energy Policy and Mines |
| Declaration of public utility | Maintained — facilitates permits and possible expropriation of land |
Economic and operational impact
For the promoter, Parques Eólicos San Lorenzo, SLU, this correction does not entail any additional cost or substantial delay in the project. The authorization remains in place and the construction schedule is not affected. However, any correction of errors in an authorization resolution requires reviewing the technical and contractual documentation that references the corrected data.
For landowners in the three affected municipalities, the impact can be significant. The declaration of public utility associated with the project enables the promoter to:
- Process permits for occupation of private land.
- Initiate forced expropriation procedures if there is no voluntary agreement.
- Access easements for evacuation infrastructure.
In projects of this scale (nearly 40 MW), the area of affected land is usually considerable. Landowners should verify whether their plots are included in the authorized layout and, if so, seek legal advice on their rights in the expropriation process.
Who does it affect?
- Parques Eólicos San Lorenzo, SLU: project promoter, holder of both authorizations. Must update its internal documentation with the corrected data.
- Landowners in Castromonte: municipality of Valladolid included in the project scope.
- Landowners in Peñaflor de Hornija: municipality of Valladolid included in the project scope.
- Landowners in Torrelobatón: municipality of Valladolid included in the project scope.
- Town councils of the three municipalities: must take into account the declaration of public utility in their urban planning and territorial organization decisions.
- Energy sector companies operating or with interests in solar-wind hybridization projects in Castilla y León: this project is a reference for the hybridization model in the region.
Practical example
An agricultural owner in Torrelobatón (Valladolid) has several cereal cultivation plots. In the property registry, he checks that one of them appears in the layout of the evacuation infrastructure of the Solar San Lorenzo B module.
Thanks to the declaration of public utility included in the authorization (and maintained after the error correction), Parques Eólicos San Lorenzo, SLU can initiate a forced expropriation proceeding or negotiate an easement with the owner. If the owner does not reach a voluntary agreement with the promoter, the administration can set compensation and proceed with occupation.
The practical recommendation in this case: review the exact layout of the project in the BOE resolution, consult with a lawyer specializing in expropriations and do not ignore any notification from the promoter or the administration.
What should companies do now?
- Parques Eólicos San Lorenzo, SLU: review all technical, contractual and administrative documentation that references the corrected data and update it with the correct values from the new resolution.
- Landowners in the three municipalities: consult the full text of the resolution in the BOE to verify whether their plots are included in the project scope and, if so, seek legal advice on their rights.
- Town councils of Castromonte, Peñaflor de Hornija and Torrelobatón: update their records and urban planning files with the corrected resolution as a current document.
- Energy sector companies with similar projects in process: note that corrections of errors in authorization resolutions are common and do not paralyze the project, but do require updating the reference documentation.
Frequently asked questions
What errors have been corrected in the San Lorenzo B authorization?
The resolution of May 7, 2026 remedies formal material errors or incorrect technical data in the original resolution of April 16, 2026. The specific errors are not detailed in the resolution text itself, but they are of a nature that does not affect the substance of the authorization.
Does this correction delay the project?
No. The correction is administrative and does not paralyze or substantially delay the project. The authorization remains in force and the promoter can continue with the construction schedule.
Can landowners oppose the expropriation?
Landowners can negotiate a voluntary agreement with the promoter or, if they disagree with the expropriation, challenge it through administrative and judicial channels. However, the declaration of public utility gives the promoter a strong legal basis to proceed with expropriation if necessary.
What is hybridization in renewable energy projects?
Hybridization is the combination of two or more renewable energy sources (in this case, solar and wind) in the same location, sharing infrastructure such as grid connection points. This optimizes land use and improves economic efficiency.
