Two new wind parks in Cuenca province receive environmental approval. The Resolution of July 3, 2026 from the Directorate General for Quality and Environmental Assessment declares the project "Wind generation modules Escuderos I and Escuderos IV, and their evacuation infrastructure, in Cuenca province" compatible with the environment, promoted by Elawan. With this EIA, the project overcomes the main administrative obstacle prior to substantive authorization.
The key differentiator of this project is its hybrid design: the wind turbines are integrated with already existing photovoltaic plants of 48.29 MW each, optimizing the use of evacuation infrastructure and maximizing generation at the same grid connection point.
What does this regulation establish?
The resolution formulates a favorable EIA for the two wind modules, which means the project can continue its processing toward final administrative authorization, provided that the imposed conditions are met. The technical and environmental aspects evaluated are as follows:
| Park | Power | Wind turbines | Municipality | Hybridized PV |
|---|---|---|---|---|
| Escuderos I Hybrid | 21.6 MW | 3 units | Palomares del Campo | 48.29 MW |
| Escuderos IV Hybrid | 28.8 MW | 4 units | Montalbo | 48.29 MW |
The evacuation infrastructure is shared and runs underground to the Torrejoncillo del Rey substation. This design reduces visual and ground impact compared to overhead lines.
The environmental analysis concludes that impacts on air quality, noise, and electromagnetic fields are compatible or not significant. For the selection of sites, a multivariate analysis between alternatives was used, prioritizing locations with less impact on protected habitats and fauna.
The conditions imposed by the EIA are structured in three areas:
- Cultural heritage: obligations for archaeological prospecting and monitoring during construction.
- Risk management: specific protocols for the construction and operation phases.
- Water quality for workers: control measures during project execution.
Economic and operational impact
The favorable EIA is a critical milestone in the value chain of a renewable project: without it, it is not possible to obtain administrative authorization or begin construction. Its achievement unlocks the following project phases and has direct impact on financing and commissioning timelines.
The wind-solar hybridization model that Elawan applies in Escuderos I and IV presents relevant economic and operational advantages for the sector:
- Grid connection point optimization: by sharing evacuation infrastructure with existing photovoltaic plants of 48.29 MW, grid access costs are reduced and the capacity of the Torrejoncillo del Rey substation is maximized.
- Generation complementarity: wind and solar have complementary production profiles (higher wind generation in winter and at night; solar in summer and during the day), which improves the utilization factor of shared infrastructure.
- Reduced environmental impact: the use of underground cabling for evacuation and site selection through multivariate analysis minimize the risks of subsequent challenges and the costs of corrective measures.
The EIA conditions on cultural heritage and risk management imply additional compliance costs (archaeological surveys, construction protocols), which must be budgeted in the detailed engineering phase.
Who does it affect?
- Elawan as direct developer: must comply with all EIA conditions to advance to final administrative authorization.
- Municipalities of Palomares del Campo and Montalbo (Cuenca): municipalities where the wind turbines are physically located, with urban planning and procedural participation implications.
- Wind developers and renewable investors operating or planning to operate in Castilla-La Mancha: this case establishes precedent on environmental assessment criteria for hybrid wind-solar projects in the region.
- Engineering and construction companies contracted for project development: must incorporate EIA conditions into their construction plans.
- Grid managers and substation operators linked to Torrejoncillo del Rey: hybridization with existing infrastructure affects evacuation capacity planning.
- Environmental and cultural heritage consultants who must execute the conditions imposed by the resolution.
Practical example
Elawan already operates the 48.29 MW photovoltaic plants in Palomares del Campo and Montalbo with access to the Torrejoncillo del Rey substation. With the approved EIA for Escuderos I Hybrid, it can add 3 wind turbines of 21.6 MW on the same evacuation infrastructure, without needing to build a new high-voltage line or request a new grid connection point.
This means that the marginal evacuation cost for the 21.6 MW wind power is significantly lower than that of an independent wind park of the same capacity, since the investment in the substation and evacuation cabling is already amortized by the existing solar plant. The same reasoning applies to Escuderos IV Hybrid with its 4 wind turbines of 28.8 MW in Montalbo.
In terms of processing, the favorable EIA issued on July 3, 2026 and published on July 20 allows Elawan to continue with the request for administrative authorization before the competent substantive body, incorporating into the file the conditions on cultural heritage, risk management, and water quality required by the resolution.
What should companies do now?
- Elawan — comply with EIA conditions: incorporate into the executive project the measures on cultural heritage (archaeological surveys), construction risk management, and water quality for workers before requesting final administrative authorization.
- Developers of similar projects — analyze the precedent: review the site selection criteria through multivariate analysis and the impact thresholds on habitats and fauna that DGCEA has applied in this case, to anticipate requirements in your own projects.
- Investors and financiers — update the risk model: the favorable EIA reduces the regulatory risk of the project; update valuation models incorporating the costs of imposed conditions and timelines for the next administrative phase.
- Municipalities of Palomares del Campo and Montalbo — prepare coordination: review the urban planning and territorial planning implications arising from the implementation of wind turbines and underground evacuation infrastructure.
- Contractor companies — budget environmental conditions: include in bids the costs of archaeological surveys, risk management protocols, and water quality controls required by the EIA.
Frequently asked questions
What is the total power of the Escuderos I and Escuderos IV wind parks approved in Cuenca?
Escuderos I Hybrid has a power of 21.6 MW with 3 wind turbines, located in Palomares del Campo. Escuderos IV Hybrid has 28.8 MW with 4 wind turbines, in Montalbo. The total wind power is 50.4 MW. Each park will be hybridized with an existing photovoltaic plant of 48.29 MW, adding 96.58 MW of hybridized solar capacity.
What does it mean for the EIA to be favorable and what conditions does it impose?
A favorable EIA means the project is environmentally viable and can continue its processing toward final administrative authorization. It is not a construction permit, but a mandatory prior requirement. The resolution imposes conditions in three areas: cultural heritage (archaeological surveys), risk management during construction and operation, and water quality for workers. Non-compliance with these conditions may halt or revoke subsequent authorization.
Why will the wind parks be hybridized with existing solar plants?
Both parks share underground evacuation infrastructure with existing photovoltaic plants of 48.29 MW each, connected to the Torrejoncillo del Rey substation. Hybridization allows optimization of grid connection point use, reduction of evacuation costs, and improvement of infrastructure utilization factor, since wind and solar have complementary generation profiles.
How were the wind turbine sites selected?
The resolution indicates that site alternatives were evaluated through multivariate analysis, selecting locations with less impact on protected habitats and fauna. The analysis concluded that impacts on air quality, noise, and electromagnetic fields are compatible or not significant at the chosen sites.
When does the EIA for the Escuderos wind parks in Cuenca come into effect?
The EIA was formulated by Resolution of July 3, 2026 and published in the BOE on July 20, 2026, the date from which it is in effect. Developer Elawan can begin from that date the procedures for final administrative authorization before the competent substantive body.
