| Publication | September 5, 2026 |

| Promoter | Sistemas Energéticos Boyal, SL |
| Project | «Boyal II» wind farm — repowering from 4.5 MW to 5 MW |

| Procedure | Simplified under RDL 20/2022 |

Sistemas Energéticos Boyal SL has prior administrative and construction authorization for the «Boyal II» wind farm as of September 5, 2026. The Resolution from the General Directorate of Energy Policy and Mines also grants the declaration of public utility, a key instrument to facilitate access to the land necessary for evacuation infrastructure.
The project is not a new installation: it is the repowering of an existing wind installation of 4.5 MW, which increases to 5 MW of installed capacity. This distinction is relevant because it explains the procedural route chosen and the favorable result of the environmental report.
What does this regulation establish?
The resolution grants two simultaneous authorizations to Sistemas Energéticos Boyal SL:
- Prior administrative authorization: enables the promoter to initiate project and contracting procedures.
- Administrative construction authorization: allows physical execution of the wind farm works and its evacuation infrastructure.
Additionally, it declares the public utility of the project, which grants the promoter the power to request the occupation or expropriation of the land necessary for evacuation infrastructure in the three municipalities.
The procedure was processed through the simplified route of Royal Decree-Law 20/2022, a regulation that reduced administrative timelines for renewable energy projects with the aim of accelerating the energy transition. This route is applicable to projects that meet certain power thresholds and technical characteristics.
From an environmental perspective, the impact report concluded that there are no significant adverse effects, conditioned on compliance with preventive and corrective measures. All consulted bodies gave their approval or did not present opposition.
| Aspect | Detail |
|---|---|
| Project type | Repowering of existing wind farm |
| Previous capacity | 4.5 MW |
| Authorized capacity | 5 MW |
| Power increase | 0.5 MW (+11%) |
| Location | Borja and Mallén (Zaragoza) and Cortes (Navarra) |
| Applicable regulatory framework | RDL 20/2022 (simplified procedure) |
| Environmental assessment | Impact report (not ordinary EIA) — no significant adverse effects |
| Public utility | Declared — facilitates land occupation for evacuation |
Economic and operational impact
For the promoter, the resolution represents the definitive unblocking of the investment. With both authorizations in hand and the declaration of public utility, Sistemas Energéticos Boyal SL can begin contracting works, acquiring or leasing land, and processing grid access permits.
The increase of 0.5 MW compared to the previous installation represents an 11% increase in generation capacity. In operational terms, this additional margin improves the economic performance of the asset without needing to build an installation from scratch, which significantly reduces investment costs and execution timelines.
Processing through the simplified procedure (RDL 20/2022) has been decisive: it allows reduction of usual administrative timelines, which accelerates return on investment and reduces regulatory uncertainty for the promoter and its financiers.
For the municipalities of Borja, Mallén and Cortes, the declaration of public utility means that landowners affected by the evacuation infrastructure may be subject to occupation or forced expropriation procedures if voluntary agreement is not reached.
Who does it affect?
- Sistemas Energéticos Boyal SL: direct promoter — can begin works and contracting immediately.
- Landowners in Borja, Mallén and Cortes: affected by evacuation infrastructure, with possibility of occupation by declared public utility.
- Municipalities of Borja and Mallén (Zaragoza) and Cortes (Navarra): municipalities where the installation and its infrastructure are located.
- Wind operators with similar repowering projects: this resolution is a precedent for successful processing through the simplified route of RDL 20/2022.
- Renewable investors and financiers: the resolution confirms the viability of the project as a financeable asset.
Practical example
A wind promoter with an existing 4.5 MW installation in operation decides to repower it to 5 MW. Instead of initiating an ordinary authorization procedure — with timelines that can exceed three years — the project is brought under the simplified procedure of RDL 20/2022.
The result, as in the case of Boyal II, is more agile processing: environmental impact report instead of complete environmental impact assessment, approval from all consulted bodies, and favorable resolution with declaration of public utility included. This allows the promoter to start works in weeks rather than years, and gives its financiers legal certainty about the asset before disbursing the investment.
The 0.5 MW increase may seem modest, but in a park with a capacity factor of 25-30%, it represents between 1,095 and 1,314 additional MWh per year — energy that is sold to market or under a PPA contract.
What should companies do now?
- Promoters with pending repowering projects: review whether your installation meets the requirements of RDL 20/2022 to use the simplified procedure and reduce timelines.
- Landowners in affected municipalities: check if your plots are included in the evacuation infrastructure route and, if so, negotiate conditions before the occupation procedure by public utility is activated.
- Investors and financiers: verify that the resolution covers both prior and construction authorization — both necessary to consider the project "ready-to-build" for financing purposes.
- Wind operators in Aragón and Navarra: analyze this resolution as a reference for processing your own projects in the same geographic area, especially regarding consulted bodies and required environmental measures.
- Legal and technical advisors in the sector: document the file as a successful case of simplified processing to advise clients with similar projects.
Frequently asked questions
What exactly does the Boyal II wind farm resolution authorize?
The resolution grants Sistemas Energéticos Boyal SL two authorizations: the prior administrative authorization and the administrative construction authorization for the «Boyal II» wind farm of 5 MW and its evacuation infrastructure. Additionally, it declares its public utility, which allows the promoter to request the occupation of land necessary for evacuation in Borja, Mallén (Zaragoza) and Cortes (Navarra).
What is the difference between the current Boyal II farm and the previous one?
The Boyal II project is a repowering of an already existing wind installation of 4.5 MW, which increases to 5 MW of installed capacity. The increase is 0.5 MW, 11% more capacity. It is not a brand new installation from scratch.
Why was it processed through a simplified procedure?
The project was brought under the simplified procedure provided for in Royal Decree-Law 20/2022, which reduces administrative timelines for renewable energy projects. This procedure allows substituting ordinary environmental impact assessment with an environmental impact report when the project meets certain conditions, as occurred in this case.
What does the declaration of public utility mean for landowners?
The declaration of public utility enables Sistemas Energéticos Boyal SL to request the occupation or forced expropriation of land necessary for evacuation infrastructure in the municipalities of Borja, Mallén and Cortes. Affected landowners can negotiate a voluntary agreement before this mechanism is activated.
Was there opposition from consulted bodies during processing?
No. According to the resolution, all consulted bodies gave their approval or did not present opposition. The environmental impact report concluded that there are no significant adverse effects, conditioned on compliance with the preventive and corrective measures established.
