Arrebol Wind Farm Cancelled: What It Means for Renewable Developers

Key data

A 58.1 MW wind project in Tarifa (Cádiz) has just been permanently archived. Statkraft Iberia Dos, SLU, requested in March 2025 the filing of the SGIISE/PEol-925 file after receiving an unfavorable resolution requiring submission to a full ordinary environmental assessment, a lengthy process with uncertain results. The Resolution of June 15, 2026 from the Directorate General for Energy Policy and Mines formally accepts that withdrawal.

The case illustrates a pattern that repeats in the sector: large-scale projects in sensitive areas that accumulate administrative and environmental obstacles until making investment unviable.

What does this resolution establish?

The resolution accepts the withdrawal filed by Statkraft Iberia Dos, SLU, of the prior administrative authorization for the «Arrebol» wind farm and its associated evacuation infrastructure. The key elements of the file are:

• Project: «Arrebol» wind farm, located in the municipality of Tarifa, province of Cádiz.
• Planned installed capacity: 58.1 MW.
• Evacuation infrastructure: Connection to the Puerto de la Cruz 220 kV substation.
• File: SGIISE/PEol-925.
• Reason for withdrawal: Unfavorable resolution requiring submission to full ordinary environmental assessment.
• Express acknowledgment by the developer: Environmental unviability is due to causes not attributable to the developer.
• Status of access and connection permits: Expired in March 2026, even before the formal resolution.

The developer expressly acknowledged that the project's unviability is due to causes beyond its control, which may be relevant for claims or recovery of guarantees and securities deposited during the process.

Economic and operational impact

For Statkraft Iberia Dos, closing the file means the definitive loss of a 58.1 MW project in one of Spain's areas with the highest wind resource. Tarifa is historically one of the most productive locations for wind energy in the Iberian Peninsula, making this cancellation particularly significant.

From an operational perspective, the sector should note the two factors that combined made the project unviable:

• Environmental barrier: The requirement for a full ordinary environmental assessment (as opposed to a simplified assessment) implies much longer timelines, greater result uncertainty, and additional processing costs that can make a project economically unviable.
• Expiration of network permits: The access and connection permits to the Puerto de la Cruz 220 kV substation expired in March 2026. Without these permits, even if the environmental assessment were passed, the project could not evacuate the generated energy.

The combination of both factors—environmental blockage plus expiration of network permits—is the scenario that most wind projects currently in processing are facing in Spain.

Who does it affect?

• Renewable energy development companies with wind projects in processing in Spain, especially in areas with environmental restrictions.
• Investors and infrastructure funds with participation in wind projects in the prior authorization phase.
• CFOs and business development directors of energy sector companies evaluating the renewable project pipeline.
• Legal advisors and permit consultants managing files before the Directorate General for Energy Policy and Mines.
• Financial entities that have granted financing or guarantees linked to wind projects in processing.
• Network operators and substation managers affected by the release of connection capacity at the Puerto de la Cruz 220 kV substation.

Practical example

A wind developer has a 50 MW project in an area of the Cádiz mountains, with access and connection permits granted in 2022 and valid until 2025. During processing, it receives a resolution from the environmental authority requiring submission to a full ordinary environmental assessment instead of the simplified one initially planned.

The ordinary assessment process can extend an additional 18 to 36 months. Meanwhile, the access and connection permits expire. Like what happened with Statkraft Iberia Dos in the Arrebol project, the company faces a double blockade: without environmental approval and without valid network permits. The most likely outcome is project withdrawal, with the resulting loss of investment made in processing and deposited guarantees.

The key to avoiding this scenario is anticipating environmental risk before network permits expire, and assessing whether to request an extension of those permits or renegotiate connection conditions while the environmental assessment is being resolved.

What should companies do now?

1. Review the status of access and connection permits for all projects in processing: check expiration dates and assess whether it is necessary to request an extension before they expire.
2. Audit the environmental risk of the pipeline: identify which projects are in areas that could require a full ordinary environmental assessment and estimate the impact on timelines and economic viability.
3. Document causes of unviability beyond the developer's control: as Statkraft Iberia Dos did, express acknowledgment that unviability is due to causes not attributable to the developer can be relevant for recovery of guarantees and securities.
4. Evaluate alternatives before withdrawing: explore whether it is possible to reformulate the project (capacity reduction, change of wind turbine location) to avoid ordinary assessment or reduce identified environmental impact.
5. Consult the archived file as a reference: the SGIISE/PEol-925 file and the resolution published in the BOE on July 10, 2026 can serve as precedent for managing similar situations before the Directorate General for Energy Policy and Mines.
