BESS La Farga Plant: 148 MW energy storage authorized in Girona

Key data

Cadaques Directorship, SL has received administrative approval to develop one of the most relevant energy storage projects authorized in Spain in 2026. The General Directorate of Energy Policy and Mines granted prior administrative authorization through a resolution dated April 20, 2026, published in the BOE on May 16, 2026.

The plant, called La Farga BESS, will have 148,394 MW of installed capacity and will be located in the Girona municipalities of Vilademuls and Sant Julià de Ramis. The authorization also covers the evacuation infrastructure necessary to connect the installation to the electrical grid.

What does this regulation establish?

The resolution grants prior administrative authorization to Cadaques Directorship, SL to build the La Farga BESS energy storage plant. This type of authorization is the first formal step in the administrative process for energy infrastructure projects in Spain: without it, progress cannot be made to the following construction and commissioning phases.

The authorized elements are as follows:

• BESS storage plant (Battery Energy Storage System) with 148,394 MW of installed capacity
• Evacuation infrastructure necessary to connect the plant to the electrical grid

Before starting construction, the promoter must demonstrate compliance with all technical and environmental conditions established in the resolution. Only once this compliance is verified can the project advance to the following phases.

BESS plants allow storing excess electrical energy—especially from renewable sources—and releasing it during periods of high demand, contributing to the stability of the electrical system and the achievement of decarbonization objectives.

Economic and operational impact

For Cadaques Directorship, SL, obtaining this authorization means unlocking the project development process. From this point forward, the promoter must direct its resources to meet the technical and environmental conditions required to begin construction.

From the perspective of the energy sector, the authorization of a 148,394 MW storage plant has relevant operational implications:

• Capacity to absorb renewable generation surpluses and reduce energy spillage
• Possibility of providing flexibility and balancing services to the electrical system operator
• Contribution to reducing dependence on backup generation with fossil fuels during peak demand periods
• Local economic impact in the municipalities of Vilademuls and Sant Julià de Ramis during the construction and operation phases

For energy sector companies, renewable promoters, and grid operators, this type of authorization sets the pace for developing storage capacity in Spain, an increasingly strategic asset for renewable integration.

Who does it affect?

• Cadaques Directorship, SL: direct promoter, obligated to comply with technical and environmental conditions before starting construction
• Municipalities of Vilademuls and Sant Julià de Ramis (Girona): territories where the installation and its evacuation infrastructure will be located
• BESS project developers and promoters in Spain: reference for administrative process and timelines for similar projects
• Electrical system operators and distribution companies: affected by the new storage and evacuation capacity that will be incorporated into the grid
• Industrial companies with high exposure to energy prices: increased storage capacity contributes to stabilizing the electricity market

Practical example

Cadaques Directorship, SL has obtained prior administrative authorization, but cannot start construction yet. The process it must follow from now on is as follows:

1. Demonstrate to the General Directorate of Energy Policy and Mines compliance with all technical conditions established in the resolution
2. Demonstrate compliance with required environmental conditions
3. Once both blocks of conditions are verified, request and obtain administrative construction authorization
4. Begin works in the municipalities of Vilademuls and Sant Julià de Ramis

This scheme is standard for any energy infrastructure promoter in Spain: prior authorization is not the endpoint, but the starting point of the actual construction process. Projects of similar magnitude—more than 100 MW of storage—typically require additional months to complete the condition verification phase and obtain construction authorization.

What should companies do now?

1. If you are Cadaques Directorship, SL or participate in the project: review in detail the technical and environmental conditions of the resolution and establish a compliance plan with milestones and responsible parties before advancing to the next administrative phase.
2. If you are a BESS project promoter in Spain: analyze this resolution as a reference for the requirements demanded by the General Directorate of Energy Policy and Mines for large-scale storage projects.
3. If you are an energy sector company or infrastructure investor: incorporate this project into your map of storage capacity under development in Spain to anticipate changes in the structure of the electricity market in Catalonia and the system as a whole.
4. If you are an industrial company in the area of influence: follow the project's evolution to assess possible opportunities for supply contracts or energy services associated with plant operation.
5. Consult the complete resolution in the BOE (reference BOE-A-2026-10654) to know the exact details of applicable technical and environmental conditions.
