| Affected parties | Enel Green Power España SL and municipalities of Teruel affected by the project |
| Category | Energy |

| Total canceled capacity | 454.4 MW (220 MW solar + 173.6 MW wind + 60.8 MW storage) |

A 454.4 MW renewable energy project in Teruel is canceled. Enel Green Power España has formally withdrawn from the prior administrative authorization of the hybrid installation "San Martín-HB1", and the General Directorate of Energy Policy and Mines has accepted this withdrawal through a resolution of June 3, 2026, published in the BOE on June 25, 2026.
The direct cause is the unfavorable environmental impact declaration issued in February 2026 by the General Directorate of Quality and Environmental Assessment. Without environmental viability, the project loses its legal basis to continue processing and Enel chooses to withdraw the application before receiving a formal denial.
What does this resolution establish?
The resolution accepts the withdrawal of Enel Green Power España regarding the hybrid installation "San Martín-HB1", composed of three separate modules:
| Module | Name | Installed capacity |
|---|---|---|
| Solar photovoltaic | San Martín | 220 MW |
| Wind | Empeltre | 173.6 MW |
| Battery storage | BESS San Martín | 60.8 MW |
The project was located in six municipalities in the province of Teruel: Albalate del Arzobispo, Híjar, La Puebla de Híjar, Samper de Calanda, Alcañiz and Andorra.
From a procedural perspective, "San Martín-HB1" was part of a set of seven hybrid installations processed jointly under file number PEol-FV-ALM-020. With this resolution, the installations are administratively separated: the San Martín project is terminated, while the other projects in the file continue their processing in separate files.
Regarding evacuation infrastructure, the resolution distinguishes two types:
- Private evacuation infrastructure of the San Martín-HB1 project: become void along with the withdrawal.
- Shared evacuation infrastructure with other projects in file PEol-FV-ALM-020: continue to be processed in separate files and are not affected by this resolution.
Economic and operational impact
The cancellation of a project of this magnitude has direct consequences in several areas:
- For Enel Green Power España: loss of all development costs incurred to date (environmental impact studies, engineering, administrative processing, land negotiation and evacuation agreements). In projects of this scale, these prior costs typically amount to several million euros.
- For the affected municipalities in Teruel: loss of income from land leasing, local taxes associated with plant activity and the potential stimulating effect on local employment.
- For the renewable sector in Spain: the case reinforces the perception that environmental risk is a critical factor in the investment equation, especially for large-scale projects located in sensitive areas.
- For other projects in file PEol-FV-ALM-020: administrative separation creates uncertainty about the timelines and processing conditions of the six remaining projects, especially regarding shared evacuation infrastructure.
This case illustrates a pattern that is consolidating in Spain: large-scale renewable projects that do not pass environmental impact assessment not only lose the investment made, but can also create uncertainty about associated projects that share infrastructure.
Who is affected?
- Enel Green Power España SL: direct promoter of the canceled project.
- Municipalities of Teruel: Albalate del Arzobispo, Híjar, La Puebla de Híjar, Samper de Calanda, Alcañiz and Andorra, which lose the expected economic impact of the project.
- Other promoters in file PEol-FV-ALM-020: the six remaining hybrid projects that were being processed jointly must now manage their processing separately.
- Investors and funds with exposure to renewables in Spain: the case is an indicator of regulatory and environmental risk that must be incorporated into project valuation models in development.
- Legal advisors and energy consultants: must update their risk analyses for projects in processing in areas with environmental sensitivity.
- Landowners and municipalities: with contracts or expectations linked to the San Martín-HB1 project, which become void.
Practical example
A renewable energy promoter has a 200 MW hybrid project in processing in an area with protected habitats, integrated into a joint file with three other projects. After two years of processing and an investment in development of several million euros, it receives an unfavorable environmental impact declaration.
As happened with "San Martín-HB1", the promoter can choose formal withdrawal before receiving an express denial. The consequences are:
- The private evacuation infrastructure of the project becomes void.
- The infrastructure shared with the other three projects in the file continues to be processed, but now in separate files, which may alter timelines and conditions.
- Land lease contracts with local owners are terminated.
- The affected municipalities lose the expected tax revenue and indirect employment.
This scenario, which was considered exceptional five years ago, is becoming a real and frequent risk for large-scale projects in Spain.
What should companies do now?
- Review the environmental status of all projects in processing: identify which are pending environmental impact declaration and at what stage they are, especially if they are located in areas with ecological sensitivity.
- Audit joint files: if you have projects processed under a joint file like PEol-FV-ALM-020, analyze how the cancellation of one would affect the others, especially regarding shared evacuation infrastructure.
- Update investment risk models: incorporate the risk of unfavorable environmental impact declaration as a critical variable in financial models of projects in development, with scenarios of total loss of prior investment.
- Review contracts with landowners and municipalities: ensure that lease agreements and local agreements include termination clauses in case of cancellation due to environmental or regulatory causes.
- Consult with specialists in environmental assessment: before advancing the processing of projects in sensitive areas, obtain an independent technical opinion on the environmental viability of the project.
Frequently asked questions
Why has Enel Green Power canceled the San Martín project in Teruel?
The direct cause is the unfavorable environmental impact declaration issued in February 2026 by the General Directorate of Quality and Environmental Assessment. Without environmental viability, the project cannot continue its administrative processing and Enel chose to submit a formal withdrawal, which was accepted by the General Directorate of Energy Policy and Mines through a resolution of June 3, 2026.
How much capacity did the canceled San Martín-HB1 project have?
The project totaled 454.4 MW of installed capacity, distributed across three modules: 220 MW of solar photovoltaic energy ("San Martín" module), 173.6 MW of wind energy ("Empeltre" module) and 60.8 MW of battery storage ("BESS San Martín" module).
What happens to the other projects in file PEol-FV-ALM-020?
File PEol-FV-ALM-020 grouped together seven hybrid installations jointly. Following the withdrawal of San Martín-HB1, the remaining projects are administratively separated and continue their processing in independent files. The evacuation infrastructure shared with other projects in the file is not affected by this resolution and continues to be processed separately.
Which municipalities in Teruel are affected by the cancellation?
The six municipalities where the project was planned are: Albalate del Arzobispo, Híjar, La Puebla de Híjar, Samper de Calanda, Alcañiz and Andorra, all in the province of Teruel. These municipalities lose the expected economic impact (leases, local taxes and indirect employment) associated with the installation.
What risk does this case represent for other renewable promoters in Spain?
The San Martín-HB1 case confirms that an unfavorable environmental impact declaration can cancel large-scale projects even after years of processing and millions of euros invested in development. Promoters must incorporate this risk into their financial models and review the environmental sensitivity of the areas where they have projects in processing, especially if they are part of joint files with shared evacuation infrastructure.
