Property owners in Calera y Chozas (Toledo) should know that the General Directorate of Energy Policy and Mines has authorized Red Eléctrica de España (REE) to build an electrical transmission line at 220 kV double circuit in that municipality. The Resolution of April 9, 2026 (BOE-A-2026-9171) is not merely an administrative procedure: it includes the declaration of public utility, which makes forced expropriation a legally available tool for executing the project.
The project consists of the entry and exit at the Calera y Chozas substation of the existing Almaraz-Ébora line, thereby reinforcing electrical transmission capacity in the center-west area of the Peninsula, a strategic area due to its proximity to the Almaraz nuclear power plant.
What does this regulation establish?
The resolution grants REE two differentiated but complementary authorizations:
- Prior administrative authorization: Confirms that the project is viable from a regulatory and energy planning perspective.
- Administrative construction authorization: Allows physical initiation of the overhead line works.
Additionally, the public utility of the installation is expressly declared. This declaration is not minor: in practice, it means that REE can initiate forced expropriation proceedings on the land necessary to trace and build the line, even if property owners do not agree to the cession.
| Element | Detail |
|---|---|
| Authorization holder | Red Eléctrica de España, SAU (REE) |
| Line type | Overhead electrical energy transmission, double circuit |
| Voltage | 220 kV |
| Project | Entry and exit at Calera y Chozas substation of the Almaraz-Ébora line |
| Location | Calera y Chozas, Toledo |
| Authorizing body | General Directorate of Energy Policy and Mines |
| Associated declaration | Public utility (enables forced expropriation) |
REE is subject to execution obligations, deadlines and technical conditions that it must comply with before putting the installation into service. Failure to meet these conditions could result in revocation of the authorization.
Economic and operational impact
For Red Eléctrica de España, this authorization marks the formal start of the construction process. The company must assume construction costs, expropriation procedures and compensation to affected property owners, in addition to complying with the deadlines and technical conditions set out in the resolution.
For property owners in Calera y Chozas, the impact is more immediate and direct:
- Their properties may be affected by easements or partial or total expropriation.
- They have the right to receive compensation, but the process can be long and complex if no prior agreement is reached with REE.
- It is advisable to seek specialized legal advice on expropriations to defend their interests and negotiate land valuation.
From the perspective of the electrical system, the project reinforces transmission capacity in the center-west peninsular area, which can have positive effects on supply security in the region, particularly relevant given the proximity to the Almaraz nuclear power plant.
Who does it affect?
- Red Eléctrica de España (REE): As the authorization holder, it must execute the project respecting the technical conditions, deadlines and obligations set out in the resolution.
- Property owners in Calera y Chozas (Toledo): Their properties may be in the line route and be subject to forced expropriation or establishment of easements.
- Calera y Chozas Municipality and local administrations: They must coordinate with REE on urban planning and territorial organization aspects related to the work.
- Energy sector companies: The improvement of transmission infrastructure in the area may affect connection planning and network access in the center-west area.
Practical example
A farmer who owns a property in Calera y Chozas whose land falls within the approved route of the 220 kV line will receive a notification from REE initiating the forced expropriation proceeding. Since the installation has been declared of public utility, the owner cannot oppose the land cession, but does have the right to:
- Participate in the valuation process and negotiate the corresponding compensation.
- Challenge the valuation if they consider it does not reflect the real value of their property.
- Claim additional damages resulting from the impact on their agricultural or livestock activity.
Without specialized legal advice, it is common for property owners to accept compensation lower than what they could obtain. In expropriations of electrical infrastructure, the difference between the initial offer and the final valuation after appeal can be significant.
What should companies do now?
- Property owners in Calera y Chozas: Check if your property is in the line route by consulting the file at the General Directorate of Energy Policy and Mines or in the text of the resolution published in the BOE.
- Seek specialized legal advice on expropriations before signing any agreement with REE. The declaration of public utility does not eliminate your right to fair compensation.
- Document the current state of your property: Photographs, valuations, agricultural yields or any data that proves the real value of the land will be useful in the negotiation process.
- Energy sector companies with interests in the area: Review whether the new infrastructure affects your connection plans or network access in the center-west peninsular area.
- REE and its contractors: Verify that the execution deadlines and technical conditions set out in the resolution are integrated into the project planning to avoid delays or non-compliance.
