Alto Cabrera Wind Farm (144 MW): Enel Green Power Authorization Denied

Key data

A 144 MW project that had been in processing for six years has ended in definitive denial. The Resolution of August 27, 2026 from the General Directorate of Energy Policy and Mines closes the file for the «Alto Cabrera» wind farm by Enel Green Power España, SL, with no possibility of ordinary appeal after the promoter's withdrawal.

The case is not a one-off accident: it is the materialization of three risks that any wind farm promoter must manage simultaneously—environmental, procedural, and grid-related. When all three fail at once, the project has no way out.

What does this resolution establish?

The resolution dismisses the application for prior administrative authorization of the «Alto Cabrera» wind farm and its evacuation infrastructure. The chain of events that led to this decision was as follows:

The key regulatory framework is Royal Decree-Law 23/2020, which establishes mandatory time milestones for renewable projects linked to grid access and connection permits. Failure to meet the favorable environmental impact declaration milestone automatically triggered the expiration of grid permits, closing the second avenue for remediation.

Economic and operational impact

For Enel Green Power España, the denial means the total loss of investment made in processing over six years: technical studies, environmental assessments, administrative fees, legal resources, and personnel costs dedicated to the file. A 144 MW project in Spain can require processing investments of several million euros before the first shovel hits the ground.

Beyond the specific case, the sectoral impact is significant:

• Risk of domino effect: Projects with weak environmental files or grid permits close to expiration face the same scenario.
• Loss of connection point: The expiration of grid access and connection permits in January 2023 means the promoter must request a new connection point in a market with high competition for available nodes.
• RDL 23/2020 deadlines as systemic risk: The royal decree-law establishes milestones that, if not met, trigger automatic expirations. Environmental inadmissibility does not stop the clock on grid permits.
• Opportunity cost: 144 MW out of the system equals renewable capacity not installed in a context of accelerated energy transition.

Who does it affect?

• Enel Green Power España, SL: Direct promoter affected by the definitive denial.
• Promoters of large-capacity wind farms in Spain: Any company with projects over 50 MW in processing must review the status of its environmental file and grid permits.
• Investors and funds with exposure to renewables in Spain: The denial affects the valuation of projects in portfolio that depend on pending authorizations.
• Legal advisors and renewable permit consultants: Must review the synchronization between environmental milestones and grid permit deadlines for their clients.
• CFOs and business development directors at utilities: Need to incorporate the risk of grid permit expiration as a variable in project viability models.

Practical example

The «Alto Cabrera» case illustrates with precision the mechanism of double failure that can sink a renewable project:

Enel Green Power España submitted its application in 2020. In April 2022, the General Directorate of Quality and Environmental Assessment declared the ordinary environmental impact assessment inadmissible for three simultaneous grounds—not one, but three—which prevented obtaining the favorable environmental impact declaration.

That favorable declaration was precisely the mandatory milestone of RDL 23/2020 to which the grid access and connection permits were linked. By failing to obtain it on time, the grid permits automatically expired in January 2023.

With the environmental file blocked and the connection point lost, the promoter filed an appeal, but in May 2026 acknowledged that it was impossible to meet RDL 23/2020 deadlines and withdrew, expressing agreement with the denial resolution. Six years of processing and the associated investment: zero result.

The operational lesson is clear: environmental inadmissibility does not freeze grid permit deadlines. Both clocks run in parallel, and if the environmental one fails, the grid one keeps running until expiration.

What should promoters do now?

1. Audit the environmental status of all projects in processing: Verify whether the ordinary environmental impact assessment has been admitted for processing and whether there are grounds for inadmissibility pending remediation.
2. Cross environmental milestones with grid permit deadlines: Identify the expiration date of each access and connection permit and calculate whether the environmental schedule allows obtaining the favorable declaration before that date.
3. Review compliance with RDL 23/2020 milestones: Check which milestones are overdue, which are approaching, and whether extension mechanisms apply.
4. Evaluate the viability of continuing with blocked projects: If the environmental file is inadmissible and grid permits have expired or are close to expiring, calculate the real cost of continuing versus abandoning and reallocating resources.
5. Strengthen the technical quality of environmental assessments before submitting them: The inadmissibility for three simultaneous grounds in «Alto Cabrera» suggests deficiencies in the submitted documentation. An external review prior to submission can avoid this scenario.
6. Inform investors and boards about expiration risk: This type of denial has direct impact on the valuation of renewable project portfolios. Transparency with governing bodies is essential.
