| Regulation | Resolution of June 3, 2026, from the General Directorate of Energy Policy and Mines — acceptance of withdrawal of file HB6 |
|---|---|
| Publication | June 25, 2026 |
| Entry into force | June 25, 2026 |
| Affected parties | Enel Green Power España, SL; municipalities of Híjar and Samper de Calanda (Teruel) |
| Category | Energy / Renewables |
| Cancelled file | El Tambor-HB6 |
| Cancelled capacity | 132.3 MW total (65.3 MW PV + 48 MW wind + 19 MW BESS) |
| Affected macro-node | Mudéjar 400 kV (1,844 MW total) |
A hybrid installation of more than 132 MW ceases to exist on paper in Teruel. Enel Green Power España, SL submitted on May 13, 2026 the withdrawal of its request for prior administrative authorization for the project «El Tambor-HB6», and the General Directorate of Energy Policy and Mines formally accepted it through a resolution of June 3, 2026, published in the BOE on June 25, 2026.
The trigger was not an isolated business strategic decision: the company expressly alleges that the conditions imposed in the favorable environmental impact assessment issued in February 2026 made it unfeasible to continue with the project as originally conceived.
What does this resolution establish?
The resolution accepts the withdrawal submitted by Enel Green Power España, SL and closes the file for prior administrative authorization of the project «El Tambor-HB6». The affected components were as follows:
| Module | Name | Installed capacity | Technology |
|---|---|---|---|
| Photovoltaic solar | El Tambor | 65.3 MW | Photovoltaic |
| Wind | La Torica | 48 MW | Wind |
| Storage | BESS El Tambor | 19 MW | Batteries (BESS) |
| Evacuation infrastructure | — | — | Grid connection |
The project was located in the municipalities of Híjar and Samper de Calanda (Teruel) and was part of the macro-node «Mudéjar 400 kV», a set of seven hybrid installations processed jointly in Teruel and Zaragoza with a total capacity of 1,844 MW. The resolution affects exclusively the HB6 file: the other six projects in the group continue their processing.
The reason for the withdrawal, as stated in the file, is the conditions of the favorable environmental impact assessment issued in February 2026. This is relevant for the sector: a favorable EIA does not equate to a clear path — it can impose technical, design or environmental compensation restrictions that make the project economically unfeasible as originally conceived.
Economic and operational impact
The cancellation of «El Tambor-HB6» has consequences on several levels:
- Lost renewable investment in Teruel: The combined 132.3 MW (PV + wind + storage) represent significant investment that will not materialize in the municipalities of Híjar and Samper de Calanda, both in a just transition zone due to the closure of the Andorra thermal power plant.
- Impact on local economic development: Renewable projects in just transition zones typically carry commitments for local employment, contracts with local suppliers and contributions to development funds. The cancellation eliminates those direct and indirect effects.
- The macro-node «Mudéjar 400 kV» loses 132.3 MW: The node goes from processing 1,844 MW with seven projects to continuing with six. This may affect the planning of shared evacuation infrastructure.
- Signal of regulatory risk for investors: The fact that a favorable EIA with excessive conditions causes the abandonment of a project of this scale is a warning signal for other promoters with similar projects in processing.
- Regional decarbonization objectives: Aragón has renewable generation commitments linked to the PNIEC. The cancellation of projects due to environmental conditions may hinder compliance with those objectives within the planned timeframes.
Who does it affect?
- Enel Green Power España, SL: Direct project promoter. Loses the investment made in processing the file and must reconsider its strategy in the area.
- Municipalities of Híjar and Samper de Calanda (Teruel): Lose the investment, employment associated with construction and operation, and income from land leasing and local taxes.
- Other promoters of the macro-node «Mudéjar 400 kV»: The remaining six projects may be affected in the planning of shared evacuation infrastructure.
- Promoters of renewable projects in processing in Spain: The cancellation due to EIA conditions is a relevant precedent for assessing the regulatory risk of their own files.
- Investors and funds with exposure to renewables in Aragón: Must review the status of the EIA of their portfolio projects and assess whether the imposed conditions are acceptable.
- Local and regional administration of Aragón: Impact on economic development plans for the just transition zone of Andorra-Sierra de Arcos.
Practical example
A renewable energy promoter has a hybrid project in processing in Teruel, within the same macro-node «Mudéjar 400 kV». Its project shares evacuation infrastructure with «El Tambor-HB6» and five other files in the group.
Following the cancellation of file HB6, this promoter must evaluate two specific issues: first, whether the exit of 132.3 MW from the node alters the sizing of the shared evacuation infrastructure and, therefore, the cost allocation among the remaining projects. Second, whether its own environmental impact assessment — pending resolution or already issued — includes conditions similar to those that led Enel Green Power to withdraw, to assess whether its project remains viable under current terms.
This preventive analysis is exactly what distinguishes development teams that avoid late surprises from those who discover unfeasibility when they have already committed significant resources.
What should companies do now?
- Promoters with projects in the macro-node «Mudéjar 400 kV»: Contact the grid operator to confirm whether the exit of file HB6 modifies the sizing or cost allocation of the shared evacuation infrastructure.
- Promoters with EIA issued or in processing: Review in detail the conditions of your environmental impact assessment. If the conditions are technically unacceptable, it is preferable to negotiate or reconsider the project before committing more investment in processing.
- Investors with a portfolio of renewable projects in Aragón: Update the regulatory risk map of their assets, incorporating the scenario of EIA with restrictive conditions as a valuation variable.
- Local administrations of Híjar and Samper de Calanda: Evaluate whether there are other promoters interested in developing renewable capacity at the same site, taking advantage of environmental studies already conducted.
- Advisors and consultants in the energy sector: Incorporate this precedent in the feasibility analyses of similar projects, especially in areas with high environmental sensitivity or in just transition zones.
Frequently asked questions
Why did Enel Green Power withdraw the «El Tambor-HB6» project?
The withdrawal, submitted on May 13, 2026, occurred as a result of the conditions imposed in the favorable environmental impact assessment issued in February 2026. A favorable EIA does not equate to authorization without restrictions: it can include technical or environmental conditions that make the project unfeasible in the terms originally conceived.
What was the total capacity of the cancelled project?
The «El Tambor-HB6» project totaled 132.3 MW in three modules: 65.3 MW photovoltaic («El Tambor»), 48 MW wind («La Torica») and 19 MW battery storage («BESS El Tambor»), plus its evacuation infrastructure. It was located in Híjar and Samper de Calanda (Teruel).
Does this cancellation affect the remaining projects of the macro-node «Mudéjar 400 kV»?
The resolution affects exclusively the HB6 file. The other six projects of the macro-node «Mudéjar 400 kV» (1,844 MW total, processed jointly in Teruel and Zaragoza) continue their processing. However, the exit of 132.3 MW may have implications for the sizing of the shared evacuation infrastructure.
What impact does this cancellation have on the just transition zones in Teruel?
Híjar and Samper de Calanda are located in a just transition zone linked to the closure of the Andorra thermal power plant. The cancellation of the project eliminates the planned renewable investment, employment associated with construction and operation, and local income derived from the project, which may slow economic development in the area and hinder regional decarbonization objectives.
Can another promoter resume the project at the same site?
The resolution closes only the file of Enel Green Power España, SL. The site in Híjar and Samper de Calanda is not reserved or blocked. Another promoter could submit a new authorization request, although they would need to start the process from the beginning, including a new environmental impact assessment.
