26 MW Solar Plant in Cádiz: Environmental Report Approved for PSFV Alíjar

Key data

The PSFV Alíjar photovoltaic plant obtains the environmental approval that clears the path toward its final authorization. With 25.99 MW of capacity and 42.44 hectares of area in the province of Cádiz, the Suresa Retama SLU project will be hybridized with the PE Alíjar II wind farm already in operation, thus optimizing the existing evacuation infrastructure. The resolution, published on 31 July 2026 in the BOE (BOE-A-2026-16732), formally opens the way for substantive authorization of the project.

What does this regulation establish?

The resolution issues a favorable simplified environmental impact report for the PSFV Alíjar photovoltaic generation module. This type of report is the mandatory prior step before the competent administration can grant substantive authorization for the energy project.

The key technical and procedural elements are as follows:

A relevant aspect of the process is that the promoter had to modify the original project design. A change in the General Urban Planning Plan (PGOU) of Jerez de la Frontera disabled a plot that was initially part of the project, forcing Suresa Retama SLU to reformulate the proposal before obtaining the favorable report.

Economic and operational impact

For the renewable energy sector, this type of resolution has a direct impact on the investment and project development chain:

• Investment unblocking: The favorable environmental report is the key that allows progress toward substantive authorization. Without it, the project cannot be built or operated.
• Hybridization as an efficiency model: By sharing evacuation infrastructure with the existing PE Alíjar II wind farm, the project reduces grid connection costs and optimizes the use of the available transformer substation.
• 3.51 km underground line: Underground placement of the 20 kV line implies higher installation costs compared to an overhead line, but reduces visual and landscape impact, which facilitates obtaining permits.
• Regulatory risk materialized and overcome: The change in Jerez's PGOU that forced project reformulation is a real example of the municipal regulatory risk faced by renewable promoters. The successful project adaptation demonstrates the importance of monitoring local urban planning.
• Bird protection measures: The conditions imposed in the report (corrective measures for bird protection) will generate additional costs for design, installation, and environmental monitoring that the promoter must budget.

Who does it affect?

• Suresa Retama SLU: Direct project promoter. Must now process substantive authorization and implement the required corrective measures for bird protection.
• Local administration of Jerez de la Frontera: Municipality where the project is located, whose PGOU already conditioned the final design.
• Local administration of El Puerto de Santa María: Municipality also affected by the project's territorial scope.
• Renewable energy sector (promoters and developers): Reference procedure for solar-wind hybridization projects in Andalusia.
• Renewable engineering and construction companies: Potential contractors for plant execution and underground evacuation line.
• Investors in renewable assets: The favorable report improves the regulatory risk profile of the project for financing and divestment purposes.

Practical example

Suresa Retama SLU initially designed the PSFV Alíjar project including a specific plot within its 42.44 ha area. During processing, the Municipality of Jerez de la Frontera modified its PGOU, which disabled that plot for energy use. The promoter had to reformulate the project — adjusting the module layout and possibly the effective area — to maintain the 25.99 MW of capacity within plots that retained the appropriate urban classification.

This case illustrates a real and frequent risk in the development of renewable plants in Spain: changes in municipal urban planning can alter projects already in environmental processing. Suresa Retama's solution was to adapt the project and select Alternative 3, which the administration valued as having the lowest environmental and territorial impact, ultimately achieving the favorable report.

What should companies do now?

1. Suresa Retama SLU: begin processing substantive authorization. The favorable environmental report is a necessary but not sufficient condition. The next mandatory step is to request administrative authorization from the competent energy authority.
2. Budget corrective measures for bird protection. The report requires specific protection measures. They must be incorporated into the executive project and the construction and operation budget.
3. Verify the urban status of all plots. The Jerez PGOU case demonstrates that municipal planning can change during processing. Monitor any urban modifications in affected municipalities (Jerez and El Puerto de Santa María).
4. Promoters of other renewable projects in Andalusia: review the hybridization procedure. This project is a reference for how to process solar-wind hybridization by leveraging existing evacuation infrastructure, reducing costs and timelines.
5. Investors: update regulatory risk analysis. With the favorable environmental report, the project overcomes one of the most uncertain barriers in renewable development. This is the time to review valuations and financing conditions.
