A 9 MW wind project in the León municipalities of Encinedo and Benuza has just been definitively cancelled. Ekain Renovables, SL has formally withdrawn its application for prior administrative authorization and construction of the "Bierzo Wind II" park, and the Directorate General for Energy Policy and Mines has accepted this withdrawal through a resolution dated June 1, 2026.
The case is not an isolated accident: it illustrates with precision the two risk vectors that can sink any renewable project in environmentally sensitive areas — the environmental barrier and the expiration of grid permits — and it does so with names, dates, and concrete consequences.
What does this resolution establish?
The resolution accepts the withdrawal submitted by Ekain Renovables, SL regarding two simultaneous authorizations: the prior administrative authorization and the administrative construction authorization of the "Bierzo Wind II" wind farm, together with its evacuation infrastructure.
The file has a relevant history for understanding accumulated risk:
- Initially, Bierzo Wind II was accumulated in the same file as Bierzo Wind I (42 MW). At some point in the process, both projects were separated into independent files.
- In December 2025, Red Eléctrica de España declared expired the grid access and connection permits corresponding to Bierzo Wind II. Without grid permits, the project cannot evacuate energy.
- In March 2026, the competent environmental body issued an unfavorable environmental impact assessment (EIA), warning of significant impacts on protected species and the landscape of the area.
- With both barriers active — environmental and grid — Ekain Renovables opted for formal withdrawal, which the Directorate General accepted on June 1, 2026.
Bierzo Wind I (42 MW), being processed in a separate file, is not affected by this resolution and continues its authorization process.
Economic and operational impact
For Ekain Renovables, SL the cancellation means the loss of all development costs accumulated over years of processing: technical studies, environmental studies, administrative fees, consulting fees, and costs associated with obtaining grid access and connection permits that Red Eléctrica de España ultimately expired.
From a sectoral perspective, the case exposes three operational risks that any wind developer must actively manage:
- Environmental risk in sensitive areas: an unfavorable EIA is a definitive block. There is no technical remedy that overcomes it without redesigning the project from scratch or changing location.
- Risk of grid permit expiration: grid access and connection permits have strict deadlines. If environmental or administrative processing is prolonged, grid permits may expire before the project reaches construction.
- Risk of accumulated files: the initial separation of Bierzo Wind I and Bierzo Wind II in a single file, and their subsequent separation, adds complexity and can generate desynchronization between the milestones of both projects.
For investors and financiers of renewable projects, this type of resolution is a warning signal about early-stage project portfolios: a project that reaches an unfavorable EIA has consumed capital without generating returns.
Who does it affect?
- Renewable energy developers with projects in processing in areas with protected species or relevant landscape values.
- Investors and infrastructure funds with positions in wind project portfolios in development phase in Spain.
- Legal advisors and environmental consultants managing authorization files for wind farms.
- CFOs and business development directors in renewable sector companies that must assess project risk in pipeline.
- Financing entities (banks, debt funds) that evaluate regulatory and environmental risk of renewable projects as a financing condition.
- Developers with projects in the province of León and Bierzo, an area that accumulates high environmental sensitivity due to the presence of protected natural areas.
Practical example
Imagine you are the development director of a renewable developer with a 12 MW wind farm in processing in a mountainous area of the northwestern peninsula, with documented presence of protected birds of prey. Your project has been in processing for three years and grid access and connection permits were granted two years ago.
The Bierzo Wind II case affects you directly on two fronts:
- Environmental front: if your environmental impact study has not adequately addressed impacts on protected species and landscape, the environmental body may issue an unfavorable EIA that cancels the project, just as happened with Bierzo Wind II in March 2026.
- Grid front: if environmental processing is prolonged beyond expectations, grid access and connection permits granted by Red Eléctrica de España may expire before you reach the construction phase, as happened with Bierzo Wind II in December 2025. You should already review the validity periods of your grid permits and act before they expire.
What should developers do now?
- Audit grid access and connection permits for all projects in your portfolio: check the expiration dates of permits granted by Red Eléctrica de España. If any are close to expiring and the project has not reached the construction phase, act before they expire.
- Review the environmental status of your projects in sensitive areas: if you have projects in processing in areas with protected species or landscape values, evaluate with your environmental team the probability of an unfavorable EIA and decide if it makes sense to continue or redesign.
- Manage the separation of accumulated files: if you have projects accumulated in the same file (as happened with Bierzo Wind I and II), ensure that the separation does not generate desynchronization in grid permit deadlines or environmental milestones.
- Inform investors and financiers about regulatory risk: this type of cancellation is a signal that investment committees and financing banks value. Document the real status of each project in pipeline with identified environmental and grid risks.
- Consult the complete resolution in the BOE (reference BOE-A-2026-23248) to learn the details of the procedure followed and extract lessons applicable to your portfolio.
Frequently asked questions
Why was the Bierzo Wind II wind farm cancelled?
The project was cancelled due to the confluence of two blocks: an unfavorable environmental impact assessment (EIA) issued in March 2026, which warned of significant impacts on protected species and landscape, and the expiration of grid access and connection permits declared by Red Eléctrica de España in December 2025. Faced with both barriers, Ekain Renovables, SL submitted a formal withdrawal, accepted on June 1, 2026.
What happens with the Bierzo Wind I wind farm (42 MW)?
Bierzo Wind I, with 42 MW, is not affected by this resolution. Although initially accumulated in the same file as Bierzo Wind II, both projects were separated into independent files. Bierzo Wind I continues its authorization process autonomously.
What are the consequences of an unfavorable EIA for a renewable project?
An unfavorable environmental impact assessment definitively blocks the authorization of the project in its current configuration. It is not an obstacle that can be overcome through ordinary appeals: the developer must either redesign the project from scratch (new location, lower capacity, different turbine arrangement) or withdraw, as Ekain Renovables did with Bierzo Wind II.
What happens if grid access and connection permits expire?
If Red Eléctrica de España declares grid access and connection permits expired, the project loses its energy evacuation point to the grid. Without that permit, the farm cannot operate even if it obtains all other authorizations. In the case of Bierzo Wind II, expiration occurred in December 2025, even before the unfavorable EIA was issued in March 2026.
Where can I consult the official resolution for the cancellation of Bierzo Wind II?
The resolution is published in the Official State Gazette with the reference BOE-A-2026-23248, with publication date November 5, 2026 and resolution date June 1, 2026.
