| Requesting company | Energías Renovables Yadisema, SL |
| Installation | Yadisema Phase II photovoltaic plant — 63.83 MW installed capacity |
| Location | Province of Toledo |
| Reason for denial | Expiration of access and connection permits to the transmission network (October 1, 2024) |

| Applicable legal framework | Law 24/2013, Electricity Sector |

A 63.83 MW photovoltaic project in Toledo loses its construction authorization not for technical or environmental reasons, but due to a calendar problem: the access and connection permits to the grid expired before the administrative process reached its end. The resolution from the Directorate General for Energy Policy and Mines, published in the BOE on June 11, 2026, is a clear warning for the Spanish renewable sector.
Energías Renovables Yadisema, SL had obtained prior administrative authorization in July 2023. However, it could not meet the technical and administrative requirements on time, and the grid permits—the essential prior step—expired on October 1, 2024. The consequence is the complete rejection of the construction authorization request.
What does this resolution establish?
The resolution rejects the request for prior administrative authorization for modifications and administrative construction authorization of the Yadisema Phase II photovoltaic installation, along with its evacuation infrastructure, in the province of Toledo.
The legal basis is clear: Law 24/2013, Electricity Sector, requires that the project holder have valid access and connection permits at the time of requesting—and obtaining—construction authorization. It is not a requirement that can be remedied afterwards.
In this case, the access and connection permits corresponded to the Leganés 220 kV substation of Red Eléctrica de España. Those permits expired on October 1, 2024, while the administrative process was still underway. Since they were not valid at the time of resolution, the Directorate General has no legal margin to grant the authorization.
| Project milestone | Date | Result |
|---|---|---|
| Prior administrative authorization obtained | July 2023 | Granted |
| Expiration of access and connection permits (Leganés 220 kV substation) | October 1, 2024 | Permits expired |
| Resolution denying construction authorization | March 4, 2026 | Rejected |
| Publication in BOE | June 11, 2026 | Final resolution |
Economic and operational impact
For Energías Renovables Yadisema, SL, the denial means the loss of all investment made in project processing: environmental impact studies, engineering, administrative fees, legal and technical fees accumulated over years of management. A 63.83 MW project represents development investment that, in the current market, can easily amount to several million euros in processing costs alone, not counting asset investment.
Beyond the specific case, the sectoral impact is relevant: this resolution confirms that expiration of grid permits is an automatic and irrevocable cause for denial under Law 24/2013. There is no possibility of extension once expired, nor of remediation during processing. The developer must restart the process from the point of requesting new access and connection permits, competing again in a market of nodes with high demand.
The operational risk is twofold: administrative timelines in Spain for projects of this scale are long (several years), while grid permits have limited validity. If processing is delayed—due to appeals, sectoral reports, regulatory changes, or any incident—the developer may reach the end of the process without valid permits.
Who does it affect?
- Photovoltaic installation developers with projects under processing in Spain, especially those with access and connection permits nearing expiration.
- Developers of other renewable technologies (wind, concentrated solar, storage) subject to the same framework of Law 24/2013.
- Investment funds and family offices with positions in renewable asset development in Spain.
- Legal and technical advisors managing portfolios of projects in different processing phases.
- CFOs and business development directors of energy companies with projects in portfolio that have not yet obtained construction authorization.
Practical example
A developer obtained in 2022 the access and connection permits for a 50 MW solar park in Castilla-La Mancha, expiring in October 2024. In parallel, it processed the prior administrative authorization—obtained in 2023—and advanced in environmental impact studies. However, the environmental impact declaration was delayed due to third-party objections, and in October 2024 the grid permits expired.
Although the developer has all technical documentation ready and prior authorization granted, it cannot obtain construction authorization. It must request new access and connection permits—competing with other projects at the same node—and restart part of the processing. The lost time and accumulated costs are not recoverable. This is exactly the scenario that Yadisema Phase II experienced.
What should developers do now?
- Audit the expiration dates of all your active access and connection permits. Identify which projects have permits nearing expiration (in the next 6-18 months) and cross that information with the actual status of administrative processing.
- Evaluate the real timelines for processing each project. If processing cannot be completed before grid permit expiration, analyze options: request extension if regulations allow, accelerate critical milestones, or prioritize resources on those projects.
- Set up expiration alerts in your portfolio management system. The October 1, 2024 expiration was not a last-minute surprise: it was a known date since permit issuance. An alert system would have allowed early action.
- Consult with your legal advisor about your margin for action under Law 24/2013 if any project is at risk of expiration. The Yadisema resolution confirms there is no margin for remediation once permits have expired.
- If permits have expired, start as soon as possible the process of requesting new access and connection permits from Red Eléctrica de España, assessing whether the original node remains viable or whether it is worth exploring alternative evacuation options.
Frequently asked questions
Why is Yadisema Phase II construction authorization denied?
Because the access and connection permits to the Leganés 220 kV substation of Red Eléctrica de España expired on October 1, 2024. Law 24/2013 of the Electricity Sector requires that the holder have valid grid permits to obtain construction authorization. Since they expired before the request was resolved, the Directorate General for Energy Policy and Mines cannot grant the authorization.
What happens if access and connection permits expire before obtaining construction authorization?
Denial is automatic under the framework of Law 24/2013. There is no possibility of remediation or extension once expired. The developer must request new access and connection permits, restarting that part of the process and competing again for capacity at the corresponding node.
Did Yadisema Phase II have any prior authorization granted?
Yes. Energías Renovables Yadisema, SL had obtained prior administrative authorization in July 2023. However, having prior authorization is not sufficient: Law 24/2013 also requires valid access and connection permits to take the next step and obtain construction authorization.
Which substation were Yadisema Phase II permits linked to?
The access and connection permits were linked to the Leganés 220 kV substation of Red Eléctrica de España. Its expiration on October 1, 2024 is the direct and sole reason for the denial recorded in the resolution published in the BOE on June 11, 2026.
How can developers avoid this risk in their projects?
By continuously monitoring the expiration dates of access and connection permits and cross-referencing them with the actual administrative processing calendar. If there is a risk that processing will extend beyond expiration, action must be taken in advance: explore extensions if regulations allow, accelerate critical milestones, or request new permits before current ones expire.
