Pinta and Guindalera Wind Farm: electrical infrastructure authorization in Valladolid

Key data

Pradamap, SLU has administrative authorization to build the electrical installations for auxiliary services of the Pinta and Guindalera wind farm, with an installed capacity of 103.5 MW in La Mudarra (Valladolid). The Resolution of October 18, 2026 from the General Directorate of Energy Policy and Mines grants both prior administrative authorization and construction authorization, the two key administrative milestones before starting work.

The processing followed the procedure established in Royal Decree 1955/2000, received favorable reports from environmental and road agencies, and obtained technical approval from Red Eléctrica de España. No objections were filed during the public information period.

What does this regulation establish?

The resolution authorizes two specific electrical installations that form part of the wind farm's evacuation infrastructure:

The supply point is located at the Villalba 220 kV sectionalizing substation, which is the energy evacuation node from the Pinta and Guindalera wind farm to the transmission network.

The authorization is granted under the framework of Royal Decree 1955/2000, which regulates the activities of transport, distribution, marketing, supply and authorization procedures for electrical energy installations. The promoter is obligated to comply with the system operator's technical standards and to obtain any additional sectoral authorizations that may apply before starting construction.

Economic and operational impact

This resolution unlocks the construction phase of the wind farm's evacuation infrastructure. Without these authorizations, the wind farm could not connect to the grid or begin generating revenue from energy sales.

The most relevant operational effects for the promoter and its environment are:

• Enablement to start work: Pradamap can begin construction of the 323-meter underground line and the 100 kVA transformation center without risk of administrative paralysis.
• Compliance from Red Eléctrica de España: Technical review has already been completed, eliminating one of the main bottlenecks in wind farm evacuation projects.
• No objections in public information: The absence of neighborhood or sectoral opposition reduces the risk of appeals that could delay the project.
• Pending obligations: The promoter must still obtain any additional sectoral authorizations that apply (urban planning, environment, roads in construction phase, etc.) before executing the work.

A 103.5 MW wind farm represents a typical investment of tens of millions of euros and a generation capacity that, at full capacity, can supply tens of thousands of homes. The authorized evacuation infrastructure is the final link connecting that generation to the national transmission network.

Who does it affect?

• Estudios y Proyectos Pradamap, SLU: Direct promoter and holder of the authorizations. Must manage construction steps and remaining sectoral authorizations.
• Contractors and electrical engineering companies: Those executing the 323-meter underground line and the 100 kVA transformation center in La Mudarra.
• Red Eléctrica de España: As system operator, must supervise the connection to the Villalba 220 kV substation and compliance with its technical standards.
• Sectoral administrations: Environmental, road and urban planning agencies in Castilla y León that must issue the additional required authorizations.
• Wind energy sector in Castilla y León: This type of resolution sets the pace for new park development in the region and serves as a reference for other promoters in processing.

Practical example

Pradamap, SLU now has in hand the two key administrative authorizations: prior authorization (which certifies project viability) and construction authorization (which enables the start of work). The next concrete step is to obtain any additional sectoral authorizations that apply—for example, permits for crossing roads or municipal work licenses—before mobilizing machinery.

Once the 323-meter underground line at 13.2 kV and the 100 kVA transformation center are built, the Villalba 220 kV sectionalizing substation will have the auxiliary electrical supply necessary to operate. This allows the Pinta and Guindalera wind farm, with its 103.5 MW of installed capacity, to evacuate energy to the national transmission network and begin generating revenue.

Without this auxiliary infrastructure, the sectionalizing substation could not operate safely, blocking the commissioning of the entire wind farm, regardless of the status of other installations.

What should companies do now?

1. Pradamap, SLU: identify pending sectoral authorizations. The resolution expressly indicates that the promoter must obtain any additional sectoral authorizations that apply. It is advisable to draw up a map of pending procedures (urban planning, environment, roads) to avoid delaying the start of work.
2. Review the system operator's technical standards. Red Eléctrica de España already gave its approval, but the promoter must comply with its technical standards during construction and commissioning. Ensure that contractors know and apply them.
3. Plan coordination with Red Eléctrica de España. Connection to the Villalba 220 kV substation will require operational coordination with the transmission network manager for testing and commissioning.
4. Other wind promoters in processing: Review whether their projects in Castilla y León follow the same RD 1955/2000 procedure and whether they are pending Red Eléctrica de España approval or favorable sectoral reports.
