A 54.425 MW renewable project in Huelva is cancelled because the approved high-speed rail route made it technically unfeasible months earlier. This is the result published in the BOE on August 21, 2026 through the Resolution from the General Directorate of Energy Policy and Mines that accepts the withdrawal of Arena Power Solar 33, SLU, and archives file PFot-544.
The case is not a simple administrative procedure: it illustrates a real and growing risk for renewable energy promoters in Spain, that of incompatibility between planned energy infrastructure and high-speed transport projects that advance in parallel.
What does this resolution establish?
The resolution includes three specific legal and administrative effects:
- Acceptance of withdrawal: The General Directorate of Energy Policy and Mines formally accepts the withdrawal of Arena Power Solar 33, SLU, from its request for administrative construction authorization for the Campos del Condado IV photovoltaic installation.
- Archive of file PFot-544: The administrative procedure is closed with no possibility of resuming it under the same file.
- Return of economic guarantees: The promoter expressly requested the return of guarantees deposited for the access and connection procedure to the transport network. The resolution confirms that such guarantees will not be executed.
The technical cause that triggered the withdrawal was the final approval of the informative study of the Seville-Huelva high-speed rail line in December 2024. That rail route directly affected the planned location for the 220 kV collector substation, an essential element to evacuate the energy generated by the plant. Without a viable substation, the project lost its technical reason for being.
Additionally, the access and connection permits to the transport network granted by Red Eléctrica had already expired in January 2025, which eliminated any possibility of reactivating the project in its original configuration.
Economic and operational impact
For the promoter, Arena Power Solar 33, SLU, the most relevant direct economic impact is the recovery of economic guarantees deposited for the access and connection procedure. By not being executed, the promoter recovers those funds, which partially limits project losses.
However, unrecoverable costs are significant:
- Investment in technical studies, engineering and administrative processing of file PFot-544.
- Costs of environmental assessment processes and access and connection permits managed with Red Eléctrica.
- Time invested in a project that will not generate income or connect to the network.
From a sectoral perspective, the cancellation of 54.425 MW represents the loss of planned renewable capacity for the province of Huelva, as well as the indirect economic impact on the municipalities of Beas and Trigueros, which will not receive the benefits associated with the installation (local employment, land leases, municipal tax revenues).
The case reveals a systemic risk: renewable promoters processing projects in areas where high-speed rail infrastructure is simultaneously planned may face incompatibilities that nullify years of investment in processing.
Who does it affect?
- Arena Power Solar 33, SLU: Direct promoter, which loses the project and processing costs, although it recovers the deposited guarantees.
- Municipalities of Beas and Trigueros (Huelva): They lose the economic and tax activity associated with a 54.425 MW installation.
- Renewable energy promoters in Spain: The case is a warning signal about the risk of overlap between energy projects and high-speed rail planning.
- Investors and financiers of photovoltaic projects: They must incorporate verification of transport infrastructure plans in the informative study phase in the project's area of influence into their due diligence.
- Advisors and consultants for energy processing: They need to expand risk analysis to planned transport infrastructure, not just those already built.
Practical example
Arena Power Solar 33, SLU, processed for years the construction authorization of Campos del Condado IV, a 54.425 MW photovoltaic plant in the municipalities of Beas and Trigueros (Huelva). To be able to evacuate the energy generated, the project included a 220 kV collector substation connected to the transport network managed by Red Eléctrica.
In December 2024, the Ministry of Transport finally approved the informative study of the Seville-Huelva high-speed rail route. That route occupied or directly conditioned the planned location for the collector substation. Without that evacuation infrastructure, the plant could not discharge energy to the network.
Faced with this situation, the promoter made the decision to formally withdraw from the request, request the return of the economic guarantees deposited, and assume as a loss the processing costs already incurred. Red Eléctrica's access and connection permits, which had expired in January 2025, confirmed that there was no room to reconsider the project under the same file.
This case is a direct example of the risk assumed by renewable promoters when transport infrastructure planning advances in parallel and without effective coordination with energy files being processed.
What should companies do now?
- Review renewable projects being processed and verify if there is any informative study or high-speed rail infrastructure project in the planning phase in the area of influence of the planned installation or its evacuation substation.
- Consult the map of rail corridors from the Ministry of Transport before committing significant investment in engineering or environmental processing of new photovoltaic projects.
- Verify the status of access and connection permits granted by Red Eléctrica: if they have expired or are about to expire, evaluate the real viability of the project before continuing to incur costs.
- Include in the due diligence of renewable projects a specific analysis of incompatibilities with planned transport infrastructure, not just those already built or under construction.
- If you decide to withdraw from a file, expressly request the return of economic guarantees deposited for the access and connection procedure, as Arena Power Solar 33, SLU, did in this case.
Frequently asked questions
Why was the Campos del Condado IV solar plant in Huelva cancelled?
Promoter Arena Power Solar 33, SLU, withdrew because the final approval of the informative study of the Seville-Huelva high-speed rail in December 2024 directly affected the 220 kV collector substation planned to evacuate the plant's energy. Without that infrastructure, the project was technically unfeasible.
What happens to the economic guarantees deposited by the promoter?
Arena Power Solar 33, SLU, expressly requested the return of economic guarantees deposited for the access and connection procedure to the transport network. The resolution confirms that such guarantees will not be executed, so the promoter will recover them.
When did Red Eléctrica's access and connection permits for this project expire?
The access and connection permits to the transport network granted by Red Eléctrica for the Campos del Condado IV plant expired in January 2025, even before the withdrawal recorded in the August 2026 resolution was formalized.
What is file PFot-544 and what does its archive imply?
PFot-544 is the code of the administrative file for construction authorization of the Campos del Condado IV photovoltaic plant. Its archive implies the definitive closure of the procedure: the project cannot be reactivated under that file and the promoter would have to start a new process from scratch if it wanted to resume any initiative in that area.
What practical lesson does this case leave for other renewable promoters?
The Campos del Condado IV case shows that photovoltaic projects can be blocked by transport infrastructure that is still in the informative study phase, not just those already built. Promoters must verify the Ministry of Transport's rail plans before committing investment in processing, especially regarding the location of evacuation substations.
