| Affected parties | Renewable energy and storage developers seeking access to the Mudéjar 400 kV node |
| Category | Energy |
| Available capacity | Up to 935.1 MW (synchronous generation modules and electric park modules) |
| Node | Mudéjar 400 kV — just transition zone Andorra-Teruel |

| Official source | BOE-A-2026-23658 |
Up to 935.1 MW of evacuation access capacity at the Mudéjar 400 kV node are available for renewable energy and storage developers. Order TED/1197/2026 regulates the procedure and requirements of the auction to allocate that capacity, published and in force since 11 November 2026.
The opportunity arises because Enel Green Power España environmentally modified its original project in the area, freeing up power that was reserved but not executed. Red Eléctrica, as the system operator, has confirmed the technical availability of that capacity at the node.
What does this regulation establish?
Order TED/1197/2026 creates a specific auction procedure to allocate the evacuation access capacity released at the Mudéjar 400 kV node. This capacity comes from the modifications provided for in basis 23 of Order TED/1182/2021, of 2 November, which regulated the access regime at just transition nodes.
The available capacity is structured in two differentiated blocks, both with the same maximum ceiling:
| Module type | Maximum available capacity | Description |
|---|---|---|
| Synchronous generation modules | 935.1 MW | Technologies with generation synchronized to the grid (e.g. biomass, geothermal, controllable hydroelectric) |
| Electric park modules | 935.1 MW | Non-synchronized generation technologies (e.g. solar photovoltaic, wind) with or without storage |
Applicants must demonstrate both technical requirements for connection and socioeconomic commitments linked to the just transition zone of Andorra-Teruel, affected by the closure of the coal-fired power plant. The urgency of the procedure is expressly justified by the economic and social impact on that region.
The regulation modifies the framework established by Order TED/1182/2021: where previously the capacity was reserved for Enel Green Power España's project, it is now open to auction among developers meeting the established requirements.
Economic and operational impact
For renewable developers, accessing 935.1 MW at a 400 kV node with confirmed technical availability is an uncommon opportunity in the Spanish market. Just transition nodes receive priority treatment in administrative processing, which can significantly reduce project development timelines.
The opportunity cost of not participating is high: the capacity will be allocated through auction and, once awarded, will not be available for new applications at that node. Companies that already have projects in the pipeline for the Teruel area should assess whether their technical assets and socioeconomic commitments are sufficient to compete.
From an operational perspective, the regulation imposes a dual requirement:
- Technical requirements: demonstrate the viability of connection to the Mudéjar 400 kV node according to the system operator's conditions (Red Eléctrica).
- Socioeconomic commitments: assume concrete obligations for impact in the just transition zone of Andorra-Teruel, linked to the closure of the coal-fired power plant.
Who does it affect?
- Developers of solar photovoltaic energy projects with capacity to connect to the Mudéjar 400 kV node.
- Developers of wind energy projects in Teruel province or areas electrically close to the node.
- Energy storage companies (batteries, hydrogen, etc.) that want to evacuate energy through that node.
- Developers of synchronous generation technologies (biomass, geothermal, hydroelectric) seeking evacuation capacity on the transmission network.
- Investment funds and renewable asset managers with projects under development in Aragón or bordering areas.
- Technical and legal advisors supporting developers in transmission network access procedures.
Practical example
A solar photovoltaic energy development company has a 200 MW project in the Andorra-Teruel region in its portfolio, currently without assigned access capacity. With the opening of the auction regulated by Order TED/1197/2026, it can request that capacity at the Mudéjar 400 kV node within the electric park modules block (which allows up to 935.1 MW in total).
To participate, the company must submit technical documentation demonstrating the viability of connection to the node and formalize the socioeconomic commitments required for the just transition zone. If the auction awards it the 200 MW requested, it obtains guaranteed access to the transmission network at a 400 kV node with technical availability confirmed by Red Eléctrica, eliminating one of the main bottlenecks in renewable project development in Spain.
What should companies do now?
- Verify if you have projects in your portfolio that can connect to the Mudéjar 400 kV node or in areas electrically close to Andorra-Teruel.
- Review Order TED/1197/2026 to identify the specific technical requirements demanded of applicants and the auction procedure timelines.
- Consult with Red Eléctrica (system operator) on the technical conditions for connecting to the Mudéjar 400 kV node for your specific technology (synchronous or electric park).
- Prepare the socioeconomic commitments required for the just transition zone of Andorra-Teruel: quantify and document them before submitting your application.
- Act with urgency: capacity is limited (935.1 MW in total per block) and will be allocated through auction. Once awarded, it will not be available at that node.
Frequently asked questions
How much capacity is available at the Mudéjar 400 kV node and how is it divided?
Order TED/1197/2026 puts up to 935.1 MW of evacuation access capacity for auction. This capacity is divided into two independent blocks: one for synchronous generation modules (up to 935.1 MW) and another for electric park modules (up to 935.1 MW). Both blocks have the same maximum ceiling.
Why is this capacity available at the Mudéjar node now?
The capacity was freed because Enel Green Power España environmentally modified its original project in the area, leaving unexecuted power that it had reserved. Order TED/1197/2026 responds to that modification (provided for in basis 23 of Order TED/1182/2021) and opens access to new developers through auction.
What requirements must applicants meet to participate in the auction?
Applicants must demonstrate two types of requirements: technical (viability of connection to the Mudéjar 400 kV node according to Red Eléctrica's conditions as system operator) and socioeconomic (impact commitments in the just transition zone of Andorra-Teruel, affected by the closure of the coal-fired power plant).
When does Order TED/1197/2026 enter into force and what is the deadline for applying?
Order TED/1197/2026 was published and entered into force on 11 November 2026. To find out the specific deadlines for submitting auction applications, you need to consult the full text of the regulation in the BOE (BOE-A-2026-23658).
What happens if I don't participate in the auction?
The available capacity (up to 935.1 MW per block) will be allocated among developers who submit applications and meet the requirements. Once assigned, it will not be available for new applications at that node. Developers with projects in the Teruel area who do not participate will lose the opportunity to access a 400 kV node with technical availability confirmed by Red Eléctrica.
