A project with 46.5 MW of installed capacity comes to an end not due to technical or environmental reasons, but due to an administrative timeline problem. The General Directorate of Energy Policy and Mines has rejected the application for prior administrative authorization of the "Umiko" photovoltaic park, promoted by Energía Inagotable de Umiko, SL, in the municipality of Tauste (Zaragoza). The resolution, published in the BOE on September 16, 2026, definitively closes file PFot-752.
The reason is clear: the grid access and connection permits at the Jundiz 220 kV substation expired on October 29, 2023 because the favorable environmental impact declaration (EIA) was not obtained within the deadline. The EIA arrived in November 2023, but it was too late: the permits had expired in accordance with Royal Decree-Law 23/2020. After the hearing process, the developer itself requested the file to be archived.
What does this resolution establish?
The resolution rejects the application for prior administrative authorization of the "Umiko" photovoltaic park. This means the project cannot advance to the following phases: construction authorization and operating authorization. The closure is definitive.
The mechanism that triggers the denial is regulated in Royal Decree-Law 23/2020, which establishes mandatory temporal milestones for holders of grid access and connection permits. If these milestones are not met within the established timeframe, the permits automatically expire. In this case, the unmet milestone was obtaining the favorable environmental impact declaration (EIA) before October 29, 2023.
The sequence of events was as follows:
- The grid access and connection permits to the Jundiz 220 kV substation were in force with a deadline linked to obtaining the EIA.
- On October 29, 2023, as the EIA had not been obtained within the deadline, the permits expired in accordance with RDL 23/2020.
- In November 2023, the EIA was finally issued, but the permits had already expired, so the favorable EIA could not reactivate the file.
- After the hearing process, the developer requested voluntary archiving of the file.
- The resolution of August 31, 2026 formalizes the definitive closure of file PFot-752.
Economic and operational impact
A 46.5 MW photovoltaic park represents a typical investment of tens of millions of euros in development, engineering, environmental studies, and administrative processing. All that capital invested in the Umiko project is lost with no possible return when the file is closed.
Beyond the specific case, the operational impact for the sector is significant:
- Irrecoverable loss of the grid access point: the grid access and connection permits at the Jundiz 220 kV substation cannot be recovered. The developer must request new permits for any future project, competing again in a highly saturated grid access market.
- No possibility of remediation: the expiration of grid access and connection permits is an incurable defect. There is no automatic extension mechanism or rehabilitation once it occurs.
- High opportunity cost: the time invested in environmental processing (several years for projects of this magnitude) cannot be recovered if the grid permits expire before the environmental assessment procedure concludes.
Who does it affect?
- Photovoltaic park developers with files in process that have valid grid access and connection permits with pending temporal milestones.
- Renewable energy sector companies that manage portfolios of solar projects in Spain.
- Investment funds and family offices with stakes in renewable energy developer companies.
- Legal advisors and processing consultants who manage administrative authorization files for generation facilities.
- CFOs and business development directors at energy companies who must monitor the status of regulatory milestones in their project portfolio.
Practical example
Imagine your company has a 30 MW photovoltaic park in process. You obtained the grid access and connection permits in 2021 and have been in the environmental impact assessment process for three years. RDL 23/2020 establishes that if you do not obtain the favorable EIA before a certain date, your permits automatically expire.
This is exactly what happened to Energía Inagotable de Umiko, SL: the EIA arrived in November 2023, but the grid access and connection permits at the Jundiz 220 kV substation had already expired on October 29, 2023, one month earlier. A single month difference between permit expiration and EIA issuance was enough for the 46.5 MW project to become impossible to continue and file PFot-752 to be permanently closed.
The lesson: it is not enough to advance in environmental processing. It is essential to monitor in parallel the expiration deadlines of grid access and connection permits and act before they expire.
What should companies do now?
- Audit the temporal milestones of all your active files: identify the exact expiration date of grid access and connection permits for each project in your portfolio. Do not assume they are valid: verify it documentally.
- Cross-reference grid permit deadlines with the environmental processing calendar: if the EIA may arrive after permit expiration, act now. Expiration is automatic and incurable.
- Consult RDL 23/2020 and its amendments: verify what temporal milestones apply to your grid access and connection permits and what the consequences of non-compliance are.
- Establish internal alerts with sufficient advance notice: schedule quarterly reviews of grid permit status, with alerts at least six months before any deadline.
- Evaluate whether it is appropriate to request information from Red Eléctrica de España (REE): in case of doubts about the status of your grid access and connection permits, contact the system operator to confirm their validity.
Frequently asked questions
Why was the Umiko solar park authorization denied?
The authorization was denied because the grid access and connection permits at the Jundiz 220 kV substation expired on October 29, 2023, as the favorable environmental impact declaration (EIA) was not obtained within the deadline established by Royal Decree-Law 23/2020. The EIA was issued in November 2023, but the permits had already expired, making it impossible to continue with file PFot-752.
What happens if the grid access and connection permits for my photovoltaic project expire?
The expiration of grid access and connection permits is an incurable defect: the authorization file cannot continue and must be archived. The developer loses the grid access point and must request new permits from scratch for any future project, with no possibility of recovering the previous ones. This is confirmed by the Umiko park case, whose file PFot-752 was permanently closed.
What is file PFot-752 and where can I consult it?
File PFot-752 is the administrative reference number assigned to the "Umiko" photovoltaic park project of 46.5 MW in Tauste (Zaragoza), promoted by Energía Inagotable de Umiko, SL. The closure resolution was published in the BOE on September 16, 2026 and can be consulted in the official BOE source.
What temporal milestones does RDL 23/2020 establish for grid access and connection permits?
Royal Decree-Law 23/2020 links the validity of grid access and connection permits to compliance with certain milestones in project processing, including obtaining the favorable environmental impact declaration within established deadlines. If these milestones are not met on time, the permits automatically expire. The Umiko case is a direct example of the consequences of this non-compliance.
Can a developer recover a file archived due to grid permit expiration?
No. Once grid access and connection permits have expired and the file has been archived, there is no rehabilitation mechanism or retroactive extension. In the case of the Umiko park, after the hearing process, the developer itself requested the file to be archived, confirming there was no way to continue. For future projects, the developer must initiate a new process to request grid access and connection permits.
