| Regulation | Resolution of April 29, 2026, from the Directorate General for Energy Policy and Mines |
|---|---|
| Publication | June 11, 2026 |
| Effective date | June 11, 2026 |
| Promoter | Proyecto Fotovoltaico Guijo, SLU |
| Installed capacity | 91 MW |
| Location | Calzadilla and Guijo de Coria (Cáceres) |
| Category | Energy |
| Type of authorization | Prior administrative authorization (first step before construction authorization) |
Proyecto Fotovoltaico Guijo, SLU receives administrative approval for a photovoltaic installation of 91 MW installed capacity in the province of Cáceres. The Resolution of April 29, 2026, published in the BOE on June 11, 2026, grants prior administrative authorization for the installation called "FV Guijo," along with its evacuation infrastructure.
This prior authorization is not equivalent to a construction permit: it is the first step in a multi-phase administrative process. The promoter must still obtain construction authorization and operating authorization before the plant can operate.
What does this regulation establish?
The resolution grants prior administrative authorization for the photovoltaic installation "FV Guijo" and its evacuation infrastructure. This is the first formal administrative act that enables the promoter to advance the project, but does not yet authorize the start of works.
The file has passed the consultation process with multiple bodies. All participated without relevant opposition:
| Consulted body | Area of competence |
|---|---|
| ADIF | Railway infrastructure |
| Red Eléctrica de España | Evacuation and connection to the electrical grid |
| Tajo River Basin Authority | Water resources and hydraulic public domain |
| Calzadilla Municipality | Local urban planning |
| Guijo de Coria Municipality | Local urban planning |
Furthermore, the promoter is obligated to comply with the favorable environmental impact statement (EIS) issued in November 2025, which includes preventive, corrective, and compensatory measures. Non-compliance with these measures may compromise subsequent authorizations.
Economic and operational impact
A 91 MW photovoltaic plant represents a significant investment in the Extremadura renewable energy sector. Although the resolution does not detail the investment amount, the project size places this installation in the large solar plants segment, with capacity to generate significant revenue from energy sales in the wholesale market or through long-term power purchase agreements (PPAs).
From an operational perspective, the main pending milestones that condition the revenue timeline are:
- Construction authorization: next mandatory administrative step before starting works.
- Municipal building permits: must be obtained from the municipalities of Calzadilla and Guijo de Coria.
- Compliance with technical conditions: required by ADIF, Red Eléctrica, Tajo River Basin Authority, and the municipalities themselves.
- Operating authorization: final step before commercial commissioning.
- Environmental measures: the preventive, corrective, and compensatory measures of the November 2025 EIS must be implemented within the timeframes it establishes.
For investors, financiers, and sector suppliers, this prior authorization significantly reduces the regulatory risk of the project, although financial close typically occurs in later phases of the administrative process.
Who is affected?
- Proyecto Fotovoltaico Guijo, SLU: direct promoter, primary party bound by the resolution's conditions.
- Municipalities of Calzadilla and Guijo de Coria (Cáceres): territories where the installation will be located; their municipalities must process building permits.
- Project investors and financiers: prior authorization is a key milestone for advancing the financing process.
- Solar construction equipment and services suppliers: administrative progress opens the door to bidding for engineering, supply, and installation contracts.
- Red Eléctrica de España: will manage the connection and evacuation of generated energy.
- Tajo River Basin Authority: will oversee compliance with conditions related to hydraulic public domain during construction and operation.
Practical example
Imagine a construction company specializing in photovoltaic plants is evaluating whether to submit a bid for the engineering, procurement, and construction (EPC) contract for FV Guijo.
With prior administrative authorization already granted on June 11, 2026, promoter Proyecto Fotovoltaico Guijo, SLU can formally begin negotiations with EPC contractors and advance in obtaining construction authorization. However, the construction company must consider that:
- Works cannot begin until construction authorization is obtained (the next step after the current one).
- The project must respect the technical conditions of bodies such as ADIF and the Tajo River Basin Authority, which may imply restrictions on the design of evacuation infrastructure.
- The environmental measures of the November 2025 EIS will generate additional execution costs that must be considered in the economic bid.
This scenario is typical for 91 MW projects: prior authorization marks the moment when the project transitions from development phase to advanced construction phase, with greater regulatory certainty for all involved parties.
What should companies do now?
- Promoter (Proyecto Fotovoltaico Guijo, SLU): immediately begin procedures for construction authorization from the Directorate General for Energy Policy and Mines, and request building permits from the municipalities of Calzadilla and Guijo de Coria.
- Review technical conditions: analyze in detail the conditions imposed by ADIF, Red Eléctrica, Tajo River Basin Authority, and the municipalities to incorporate them into the executive project.
- Comply with the environmental impact statement: implement the preventive, corrective, and compensatory measures established in the November 2025 EIS from the start of works.
- Suppliers and contractors: monitor progress toward construction authorization to be positioned when the EPC bidding process opens.
- Investors and financiers: update the project's regulatory risk models, given that prior authorization reduces administrative uncertainty, although it does not eliminate risks in subsequent phases.
Frequently asked questions
What is prior administrative authorization and what steps remain for FV Guijo to enter operation?
Prior administrative authorization is the first formal act that enables the promoter to continue the process. After it, Proyecto Fotovoltaico Guijo, SLU must obtain construction authorization, building permits from the municipalities of Calzadilla and Guijo de Coria, and finally operating authorization before the plant can generate and sell energy.
What bodies have intervened in the FV Guijo file and with what result?
ADIF, Red Eléctrica de España, the Tajo River Basin Authority, and the municipalities of Calzadilla and Guijo de Coria have been consulted. None presented relevant opposition, which has allowed prior authorization to be granted without blocking conditions.
When was the environmental impact statement for FV Guijo issued and what does it require of the promoter?
The favorable environmental impact statement (EIS) was issued in November 2025. The promoter is obligated to comply with all preventive, corrective, and compensatory measures established in that statement during construction and operation of the plant.
What capacity does the FV Guijo solar plant have and where is it located exactly?
The photovoltaic installation "FV Guijo" has an installed capacity of 91 MW and is located in the municipal areas of Calzadilla and Guijo de Coria, in the province of Cáceres (Extremadura).
Can construction of FV Guijo begin after this resolution?
No. Prior administrative authorization does not enable the start of works. The promoter must first obtain construction authorization from the Directorate General for Energy Policy and Mines, and building permits from the municipalities of Calzadilla and Guijo de Coria.
