220 kV Power Line Borox-Fuencarral: Environmental Report Approved and What It Means for Envatios XIX

Key data

The modification of the 220 kV power line route between the Borox and Fuencarral substations now has environmental approval. The Resolution of July 23, 2026 from the General Directorate of Quality and Environmental Assessment (reference BOE-A-2026-17715) issues a favorable environmental impact report, clearing the way for Envatios Promoción XIX SL to move forward with the execution project, provided it incorporates the established environmental requirements.

The route change affects 6,584 meters of the electrical evacuation line, which serves photovoltaic solar parks located in the provinces of Toledo and Madrid. The technical solution adopted is mixed overhead-underground: overhead lines are maintained in sections that do not generate conflict, and underground placement is used at points where the line crosses protected ecological corridors in the Community of Madrid.

What does this regulation establish?

The resolution approves the simplified environmental impact report for the modification of section DC 220 kV APC-98-APC-125 of the evacuation line associated with the photovoltaic solar parks of promoter Envatios Promoción XIX SL. The key elements it establishes are:

The process has involved consultations with multiple administrations and technical justification of the infeasibility of additional underground placements beyond those already planned in ecological corridors. The resolution concludes that simplified assessment is sufficient to authorize the modified project.

Economic and operational impact

For Envatios Promoción XIX SL, approval of the environmental report is a necessary condition to execute the electrical evacuation infrastructure for its photovoltaic solar parks in Toledo and Madrid. Without this favorable report, the project could not move forward.

The main operational impacts are:

• Obligation to redesign the execution project: The promoter must incorporate all environmental requirements set out in the resolution before starting construction. This may involve adjustments in engineering, timelines, and construction budget.
• Underground placement in two ecological corridors: Sections crossing the Eastern Corridor and Los Yesos Corridor of the Community of Madrid must be underground, which represents a higher construction cost than conventional overhead lines.
• Technical justification of infeasibility of additional underground placements: The promoter has already demonstrated to the administration that it is not technically feasible to expand underground placement beyond the required sections, which limits future claims in that regard.
• No ordinary assessment: Since ordinary environmental impact assessment is not required, the promoter avoids a longer and more costly procedure, which accelerates startup timelines.

Who does it affect?

• Envatios Promoción XIX SL: Direct promoter. Must adapt the execution project to the approved environmental requirements.
• Municipalities of Morata de Tajuña and Arganda del Rey: Route changes were specifically designed to avoid impacts to active mining concessions in these municipal areas.
• Community of Madrid: The Eastern and Los Yesos ecological corridors are protected through mandatory underground placement in those sections.
• Holders of mining concessions in Morata de Tajuña and Arganda del Rey: The new route avoids interference with their active concession rights.
• Administrations consulted during the process: Multiple agencies participated in the simplified environmental assessment procedure.

Practical example

Envatios Promoción XIX SL plans to evacuate energy generated by its photovoltaic solar parks in Toledo and Madrid through this 220 kV line. The original route crossed areas with active mining concessions in Morata de Tajuña and Arganda del Rey, which created a legal and technical conflict that blocked the project.

With the approved modification, the route deviates by 6,584 meters to bypass those conflicting areas. At points where the new route crosses the ecological corridors of the Community of Madrid, the line is underground. In the rest, it remains as overhead lines to reduce costs.

The result: the promoter obtains environmental approval without needing an ordinary assessment (longer and more costly), but assumes the additional cost of underground placement in the sections of the Eastern and Los Yesos corridors, and the obligation to reformulate the execution project with all environmental requirements before starting construction.

What should companies do now?

1. Review the complete environmental impact report: Envatios Promoción XIX SL must read the entire Resolution of July 23, 2026 (BOE-A-2026-17715) to identify all applicable environmental requirements.
2. Incorporate requirements into the execution project: Before starting any construction, the promoter must update the technical project to reflect the approved environmental conditions, including underground placements in the Eastern and Los Yesos ecological corridors.
3. Coordinate with affected municipalities: Maintain communication with the town councils of Morata de Tajuña and Arganda del Rey to ensure that the new route does not generate additional conflicts with active mining concessions.
4. Verify that no additional authorizations are required: The resolution confirms that ordinary environmental impact assessment is not necessary, but the promoter must check if other sectoral licenses or permits are pending for the modified section.
5. Document the technical justification of infeasibility of additional underground placements: Preserve all technical documentation that proves why it is not feasible to expand underground placement beyond the required sections, in case it is required in later phases of the procedure.
