Enel Green Power Spain obtains administrative approval for the "Calandrias" photovoltaic module, with 213.094 MW of installed capacity, in the Teruel municipalities of Híjar, Samper de Calanda and Alcañiz. The Resolution of June 1, 2026 from the General Directorate of Energy Policy and Mines, published in the Official Gazette on June 24, 2026, grants preliminary administrative authorization and includes evacuation infrastructure at 400 kV.
In the same accumulated file, the application for the "El Castillo" wind module is dismissed, with 111.6 MW, also promoted by Enel Green Power Spain in the same area. The installation is part of a file that groups six other hybrid projects in Teruel and Zaragoza.
What does this regulation establish?
The resolution grants preliminary administrative authorization —the first step in the process of enabling large electrical generation installations— for the "Calandrias" solar photovoltaic module, part of the hybrid project called "HB5-Regallo".
The key elements regulated by the resolution are as follows:
| Element | Detail |
|---|---|
| Authorized installation | "Calandrias" solar photovoltaic module, 213.094 MW |
| Evacuation infrastructure | Included in authorization, at 400 kV |
| Denied installation | "El Castillo" wind module, 111.6 MW |
| File framework | Accumulated file with six other hybrid projects in Teruel and Zaragoza |
| Consulted bodies | AESA, Ebro River Basin Authority, ADIF, local administrations |
| Special conditions | Technical and urban planning, especially in Alcañiz |
| Required coordination | With other renewable promoters in the area to avoid incompatibilities |
| Pending steps | Construction authorization + environmental impact declaration |
It is essential to understand that this authorization does not enable the start of works. This is preliminary authorization, which certifies the administrative viability of the project. The promoter must complete the process with construction authorization and environmental impact declaration before being able to execute the installation.
Economic and operational impact
The approval of a plant with 213 MW of photovoltaic power has a significant impact on the energy and economic fabric of Teruel province and the surrounding Zaragoza area:
- For Enel Green Power Spain: it represents the most relevant formal advance of the "HB5-Regallo" project in its solar component, although the denial of the "El Castillo" wind module (111.6 MW) reduces the total scope of the planned hybrid project.
- For other renewable promoters in the area: the resolution imposes the obligation to coordinate to avoid technical incompatibilities, which may condition the timelines and designs of neighboring projects.
- For local administrations: the municipalities of Híjar, Samper de Calanda and Alcañiz must supervise compliance with technical and urban planning conditions, with special attention in Alcañiz.
- For the electrical system: connection at 400 kV implies integration into the high-voltage transmission network, with impact on the planning of Red Eléctrica de España.
The denial of the wind module represents a reduction of 111.6 MW compared to the total capacity that the promoter intended to develop in this file, which requires rethinking the hybrid generation strategy in the area.
Who does it affect?
- Enel Green Power España, SL: direct promoter, which must now complete the construction and environmental impact phases for the photovoltaic module, and evaluate alternatives for the denied wind module.
- Other renewable energy promoters in Teruel and Zaragoza: the six hybrid projects in the accumulated file and any promoter with installations in the area must coordinate their projects with the "Calandrias" module.
- Local administrations of Híjar, Samper de Calanda and Alcañiz: must manage the urban planning and technical conditions derived from the resolution.
- Consulted sectoral bodies: AESA, Ebro River Basin Authority and ADIF maintain supervisory competencies over specific aspects of the installation.
- Project investors and financial partners: the partial denial (wind module) and pending additional authorizations affect the project timeline and financial model.
Practical example
A renewable promoter with a 50 MW photovoltaic project in the Bajo Aragón region (Teruel) that shares evacuation infrastructure with Enel Green Power's "Calandrias" module must, from now on, technically coordinate its grid connection design with the authorized promoter to avoid incompatibilities in access to the 400 kV line.
If it does not, the General Directorate of Energy Policy and Mines may condition or deny its own construction authorization, delaying the project by months or years. Coordination is not voluntary: the resolution expressly imposes it as a condition of the authorization granted to Enel Green Power.
What should companies do now?
- Enel Green Power Spain: immediately initiate procedures for construction authorization and environmental impact declaration of the "Calandrias" module, as preliminary authorization does not enable works.
- Renewable promoters in the area: review whether their projects in Teruel or Zaragoza share evacuation infrastructure with "HB5-Regallo" and establish technical coordination mechanisms with Enel Green Power Spain.
- Investors and financiers: update project financial models to reflect the denial of the wind module (111.6 MW) and additional pending processing timelines.
- Local administrations of Alcañiz, Híjar and Samper de Calanda: review the specific urban planning conditions included in the resolution and prepare the corresponding monitoring reports.
- Any promoter with projects in processing in the area: consult the accumulated file to learn about the six additional hybrid projects that are part of the same procedure and evaluate possible interferences.
Frequently asked questions
What is preliminary administrative authorization and what is missing for the plant to be built?
Preliminary administrative authorization is the first formal step in the process of enabling large electrical installations. It certifies the administrative viability of the project, but does not allow starting works. Enel Green Power Spain must also obtain construction authorization and environmental impact declaration before being able to execute the "Calandrias" photovoltaic module of 213.094 MW.
Why is the "El Castillo" wind module of 111.6 MW denied?
The resolution dismisses the application for preliminary administrative authorization for the "El Castillo" wind module, with 111.6 MW, although the specific technical reasons for the denial are not detailed in the published summary. The "Calandrias" photovoltaic module does receive authorization within the same accumulated file "HB5-Regallo".
What bodies have intervened in the processing and what conditions do they impose?
The processing has required reports from AESA (State Aviation Safety Agency), the Ebro River Basin Authority, ADIF and local administrations of the affected municipalities. The resolution imposes technical and urban planning conditions, with special attention to the municipality of Alcañiz.
What does the obligation to coordinate with other renewable promoters imply?
The resolution requires that Enel Green Power Spain coordinate with other renewable promoters in the area to avoid technical incompatibilities, especially in access to evacuation infrastructure at 400 kV. This coordination is an express condition of the authorization and its non-compliance may affect the processing of later phases of the project.
How many projects are part of the accumulated file "HB5-Regallo"?
The accumulated file includes the "Calandrias" photovoltaic module (authorized) and the "El Castillo" wind module (denied), plus six other hybrid projects in the provinces of Teruel and Zaragoza. In total, the file groups eight renewable generation initiatives processed jointly by the General Directorate of Energy Policy and Mines.
