Enel Green Power España can move forward with the construction of its battery storage system in Teruel after receiving prior administrative authorization from the Directorate General for Energy Policy and Mines. The resolution, dated April 1, 2026 and published in the BOE on July 30, 2026 (BOE-A-2026-16634), has two sides: it authorizes the BESS Mudéjar and, at the same time, closes the door to the San Jorge wind farm.
The decision is relevant not only for Enel, but for any renewable energy developer in Aragón: it illustrates how overlap between projects can block a 75 MW installation already in processing.
What does this resolution establish?
The resolution regulates two differentiated administrative decisions on Enel Green Power España projects in the municipalities of Andorra and Albalate del Arzobispo (Teruel):
| Project | Type | Power | Decision | Reason |
|---|---|---|---|---|
| BESS Mudéjar | Battery storage (solar hybridization) | 41.58 MW | Authorized | Passes ordinary environmental impact assessment; favorable reports from regional and state bodies |
| San Jorge | Wind module | 75 MW | Rejected | Overlap with third-party projects, including Copenhagen Infrastructure |
The BESS Mudéjar will be hybridized with the Mudéjar-Millán Hernández Bonaga photovoltaic farm (66 MW), already operational. The authorization also includes the evacuation infrastructure necessary to connect the battery system to the grid. The file has completed an ordinary environmental impact assessment and has obtained reports from multiple regional and state bodies, indicating a complex and lengthy processing procedure.
The rejection of the San Jorge wind module is not due to technical deficiencies in Enel's project, but to a concurrence conflict: another developer — Copenhagen Infrastructure — has rights or files that geographically overlap with the wind proposal.
Economic and operational impact
For Enel Green Power España, the resolution represents a mixed result with clear operational implications:
- Confirmed opportunity: The 41.58 MW BESS Mudéjar can advance to the next administrative phases (construction authorization, commissioning certificate). Hybridization with the existing 66 MW photovoltaic farm optimizes the use of already installed evacuation infrastructure and improves the manageable generation profile.
- Loss of wind capacity: The 75 MW San Jorge module is excluded from Enel's portfolio in this area, at least in its current configuration. Reformulating the project would require a new processing procedure with associated costs and timelines.
- Overlap risk for the sector: The Copenhagen Infrastructure case is a warning signal for any developer with projects in processing in Aragón: concurrence with third parties can block large installations even in advanced phases of the file.
From the perspective of the electricity market, the addition of 41.58 MW of storage to a 66 MW photovoltaic farm improves the manageable dispatch capacity of the installation, which has value both in the wholesale market and in the provision of adjustment services to the system operator.
Who does it affect?
- Enel Green Power España, SLU: Direct developer. Must activate the next phases for BESS Mudéjar and decide whether to reformulate or abandon the San Jorge wind project.
- Renewable energy developers with projects in Teruel and Aragón: The rejection of San Jorge due to overlap with Copenhagen Infrastructure is a precedent affecting any developer with files in high-concurrence areas.
- Copenhagen Infrastructure: Its project in the area is strengthened by the elimination of competition from Enel's San Jorge wind module.
- Advisors and consultants for renewable processing: Must review concurrence maps for their clients before advancing authorization requests in saturated areas.
- Municipalities of Andorra and Albalate del Arzobispo: Municipalities directly involved in the territorial development of these projects.
Practical example
Imagine a renewable energy developer with a 60 MW wind project in processing in the Andorra region (Teruel), an area where the Mudéjar-Millán Hernández Bonaga photovoltaic farm already operates and where Copenhagen Infrastructure has active files.
Before submitting or continuing its prior administrative authorization request, this developer should verify whether its implementation area overlaps with the polygons of already authorized or advanced processing projects. The San Jorge case demonstrates that the Directorate General for Energy Policy and Mines rejects projects due to overlap, even when the affected developer (Enel) is a first-tier operator with proven technical and financial capacity.
The cost of not performing this prior verification can be the total loss of investment in processing (environmental impact studies, engineering, administrative fees) of a 75 MW project, as occurs with the San Jorge module.
What should companies do now?
- Enel Green Power España: Activate the next administrative phases for BESS Mudéjar (construction authorization request) taking advantage of the fact that prior authorization is already granted. Evaluate whether to reformulate the San Jorge wind module in an alternative location without overlap.
- Developers with projects in Aragón: Immediately review the concurrence maps of their files in processing. Request updated information from the Directorate General for Energy Policy and Mines about third-party projects in the same areas.
- Processing advisors: Include overlap analysis with third-party projects as a mandatory step in the due diligence prior to any prior administrative authorization request in high-density renewable project areas.
- Renewable energy investors: Consider concurrence risk as a valuation variable in projects in processing, especially in autonomous communities with high saturation of requests such as Aragón.
Frequently asked questions
What is BESS Mudéjar and what authorized power does it have?
BESS Mudéjar is an energy storage system with batteries of 41.58 MW installed power, promoted by Enel Green Power España. It will be hybridized with the Mudéjar-Millán Hernández Bonaga photovoltaic farm of 66 MW, already operational in the municipalities of Andorra and Albalate del Arzobispo (Teruel). Prior administrative authorization was granted by resolution of April 1, 2026.
Why was Enel's San Jorge wind farm rejected?
The 75 MW San Jorge wind module was rejected primarily due to overlap with third-party projects in the same area, specifically mentioning the Copenhagen Infrastructure project. This is not a technical or environmental problem with Enel's project, but a concurrence conflict between files.
What phases remain pending for BESS Mudéjar to enter operation?
The resolution grants prior administrative authorization, which is the first step in the process. Enel Green Power España must subsequently obtain construction administrative authorization and, finally, the commissioning certificate before the installation can operate. The authorization also includes the necessary evacuation infrastructure.
What risk does a renewable developer face if their project overlaps with a third party's?
As illustrated by the San Jorge wind module case, overlap with third-party projects can lead to total rejection of the prior administrative authorization request, even in large-scale projects (75 MW in this case). This implies the loss of all investment made in processing: environmental impact studies, engineering, fees and time invested.
What bodies have intervened in the processing of BESS Mudéjar?
The file has passed an ordinary environmental impact assessment and has obtained reports from multiple regional and state bodies, as indicated in the resolution. Authorization is the responsibility of the Directorate General for Energy Policy and Mines, dependent on the Ministry for Ecological Transition and Demographic Challenge.
