29.5 MW Solar Photovoltaic Plant in Granada: Acciona Expands Renewables by Hybridizing with Wind Power

Key data

Corporación Acciona Eólica, SLU expands its renewable capacity in the province of Granada with a new photovoltaic solar plant of 29.537 MW that will be hybridized with the Los Morrones wind farm, of 30 MW, already in operation. The Resolution of May 4, 2026 from the General Directorate of Energy Policy and Mines grants prior administrative authorization for both the photovoltaic module and its evacuation infrastructure, in the municipalities of Baza and Zújar.

The key to this operation is not just the installed capacity: it is the hybridization model. Instead of building an independent evacuation line for the solar plant, Acciona reuses the infrastructure already existing from the wind farm. This has direct implications for costs, timelines, and system efficiency.

What does this regulation establish?

The resolution grants Corporación Acciona Eólica, SLU the prior administrative authorization for two differentiated elements:

• The Los Morrones photovoltaic generation module, with an installed capacity of 29.537 MW.
• The associated electrical evacuation infrastructure, which will be shared with the existing wind farm.

Prior administrative authorization is the first formal step in the authorization process for electrical generation facilities in Spain. It does not yet enable construction or operation, but it does validate the project from the perspective of energy policy and allows progress toward the following phases of the administrative procedure.

The central concept of this resolution is hybridization: the integration of a new generation technology (photovoltaic) with an already existing facility (wind) under the same connection point to the grid. This formula is expressly contemplated in Spanish policy for accelerating renewable deployment to meet European climate objectives.

Economic and operational impact

Hybridization has a direct and clear economic impact for Acciona: it does not need to build independent electrical power lines for the solar plant. The evacuation infrastructure of the Los Morrones wind farm is already installed and connected to the grid. Reusing it means significant savings in civil works costs and processing timelines.

From an operational perspective, the combination of wind and solar generation at the same connection point allows for greater supply stability: wind and sun have complementary generation profiles (wind is usually stronger at night and in winter; sun during the day and in summer). This improves the utilization factor of the grid connection point.

For the electrical system as a whole, this model reduces the need for new grid infrastructure, one of the main bottlenecks in renewable deployment in Spain.

Who does it affect?

• Corporación Acciona Eólica, SLU: direct holder of the authorization. Must complete the following administrative phases (construction authorization, operating authorization) before operating the plant.
• Municipalities of Baza and Zújar (Granada): territory where the facility will be located. May be affected in terms of land use planning, local employment during construction, and generation of economic activity.
• Renewable project promoters in Spain: this resolution is a reference for the hybridization model that the General Directorate of Energy Policy and Mines is validating. Companies with existing wind farms can analyze whether their facilities are candidates for a similar process.
• Grid managers and system operators: hybridization affects the planning of evacuation capacity in the area.

Practical example

A renewable sector company that has an operational wind farm of, for example, 30 MW with its evacuation infrastructure already installed can consider adding a photovoltaic module of similar capacity to that of Los Morrones (29.537 MW) without needing to request a new grid connection point or build new power lines.

The process begins with a request for prior administrative authorization from the General Directorate of Energy Policy and Mines, as Acciona has done. Once this authorization is obtained—which is the step covered by this resolution—the promoter must continue with construction authorization and, subsequently, operating authorization before putting the facility into operation.

In the specific case of Los Morrones, the sum of both facilities reaches approximately 59.5 MW of combined renewable capacity (30 MW wind + 29.537 MW photovoltaic) sharing the same evacuation infrastructure.

What should companies do now?

1. If you are a renewable promoter with existing wind farms: analyze whether your facilities have available evacuation capacity to add a hybridized photovoltaic module. This resolution confirms that the General Directorate of Energy Policy and Mines is approving this type of project.
2. Review the status of your grid connection points: hybridization is only viable if the existing connection point has sufficient capacity to absorb the additional generation from the solar plant. Consult with your grid manager.
3. Initiate the prior administrative authorization procedure if your project meets the technical and location requirements. This is the first formal phase and the one that opens the rest of the process.
4. Coordinate with the affected municipalities from the start of the project. Baza and Zújar are involved in this case; in similar projects, early municipal coordination reduces risks of opposition or administrative delays.
5. Monitor hybridization resolutions published in the BOE to identify trends in approval criteria and technical models that the administration is validating.
