Acciona cancels Mulatón 43 MW solar plant in Ayora: what it means for the energy sector

Key data

The cancellation of the Mulatón solar plant definitively closes a file that had been active since December 2022. Corporación Acciona Eólica, SL submitted the formal withdrawal on March 16, 2026 under Article 94 of Law 39/2015, and the General Directorate of Energy Policy and Mines accepts it through a resolution of April 27, 2026, published in the BOE on June 8, 2026.

The immediate trigger was a corporate split: in February 2026, Acciona Eólica del Levante and Corporación Acciona Eólica informed the administration that they no longer belonged to the same business group as of December 2025, requesting the de-accumulation of the files being processed jointly. Shortly after, the promoter opted directly for total withdrawal of the project.

What does this resolution establish?

The resolution from the General Directorate of Energy Policy and Mines formalizes four specific legal effects:

• Acceptance of the withdrawal submitted by Corporación Acciona Eólica, SL on March 16, 2026.
• Definitive archiving of the file for prior administrative authorization, administrative construction authorization, environmental impact declaration and public utility declaration of the hybrid photovoltaic installation «Mulatón».
• Cancellation of the evacuation infrastructure associated with the project, which also formed part of the original request.
• Confirmation of promoter compliance after the mandatory hearing procedure, closing the proceedings without pending appeals.

The project had been processed jointly with other photovoltaic plants from the Acciona group. The corporate separation between Acciona Eólica del Levante and Corporación Acciona Eólica — effective since December 2025 — made it impossible to maintain accumulated processing, which led to the withdrawal.

Economic and operational impact

The cancellation of Mulatón has direct consequences for several actors in the Valencian energy ecosystem:

• Lost renewable capacity: almost 43 MW of photovoltaic power that will not be incorporated into the electrical grid of the Comunitat Valenciana, with the consequent delay in the region's energy transition objectives.
• Evacuation infrastructure: the evacuation network planned for the project is also cancelled, which may affect grid planning in the Ayora area.
• Impact on Acciona's portfolio: the de-accumulation of files and subsequent withdrawal reflect an internal reorganization of the group following the corporate separation of December 2025. Other group projects in the area could be affected by the same restructuring.
• Affected administrations: both the Generalitat Valenciana and the Albacete administration (mentioned in the scope of impact) will need to recalibrate their forecasts for installed capacity in the area.

Who does it affect?

• Corporación Acciona Eólica, SL: direct promoter that withdraws the request and closes the file.
• Acciona Eólica del Levante: entity that, following the group separation in December 2025, prompted the de-accumulation of files.
• General Directorate of Energy Policy and Mines: instructing body that accepts the withdrawal and archives the file.
• Comunitat Valenciana administration: loses a renewable installation of almost 43 MW in its territory.
• Albacete administration: affected in the scope of the associated evacuation infrastructure.
• Other renewable promoters in the Ayora area: the cancellation may open or modify access to grid connection points previously reserved for this project.
• Investors and funds with exposure to Acciona's renewable portfolio: the corporate restructuring and project cancellation are relevant signals for monitoring the group's portfolio.

Practical example

A renewable energy promoter that had planned the connection of its own photovoltaic plant in the Ayora (Valencia) area and that depended on the evacuation infrastructure shared with the Mulatón project must now act:

1. Verify with the grid operator if the connection point or evacuation capacity provided for its project is modified following the archiving of the Mulatón file.
2. Review whether its access and connection request was processed jointly with files from the Acciona group, since the de-accumulation requested in February 2026 may have generated changes in processing.
3. Consult with the General Directorate of Energy Policy and Mines the updated status of available evacuation points in the area, as the capacity not used by Mulatón could be redistributed.

What should companies do now?

1. Promoters with projects in the Ayora area: contact Red Eléctrica / grid operator to verify if the cancellation of Mulatón frees up evacuation capacity or modifies the conditions for grid access in the area.
2. Acciona group companies with accumulated files: review the status of each individual file following the de-accumulation requested in February 2026, as each project must now be processed independently.
3. Investors with exposure to the Valencian renewable sector: update portfolio models by removing the 42.99 MW of Mulatón from any forecast of future installed capacity in the Comunitat Valenciana.
4. Energy advisors and consultants: inform your clients about the potential availability of connection points in the Ayora area, which may have been freed following the archiving of the file.
5. Local and regional administrations: update energy infrastructure development plans in the La Canal de Navarrés region (Ayora) by removing Mulatón's capacity from forecasts.
