A new biomethane injection point arrives at the Salamanca-Zamora pipeline. The General Directorate of Energy Policy and Mines has granted Enagás Transporte SAU administrative authorization, approval of the execution project, and declaration of public utility to build the position O-12X with measurement station G-65 in Peleas de Abajo (Zamora). The resolution, published on May 16, 2026, is a concrete piece within the decarbonization strategy of the Spanish gas sector.
For biomethane producers operating or planning to operate in Castilla y León, this infrastructure represents direct access to the natural gas transport network managed by Enagás. For landowners in Peleas de Abajo, the declaration of public utility has immediate implications for the availability of their properties.
What does this regulation establish?
The resolution grants three simultaneous authorizations to Enagás Transporte SAU for the project called Annex to the Salamanca-Zamora pipeline. New position O-12X with measurement station G-65 for biomethane injection:
| Authorization granted | What it allows |
|---|---|
| Administrative authorization | Build and operate the new connection infrastructure to the Salamanca-Zamora pipeline |
| Approval of the execution project | Execute the works according to the technical project presented, including position O-12X and measurement station G-65 |
| Declaration of public utility | Facilitate the occupation of necessary land in Peleas de Abajo and streamline associated administrative procedures |
The installation has a clear functional objective: to allow the injection of biomethane into the natural gas transport network. Biomethane is a renewable gas produced from organic waste or biomass that, once purified, is technically equivalent to natural gas and can circulate through the same pipeline infrastructure.
This action is framed within the objectives of integrating renewable gases into the existing gas infrastructure, without the need to build parallel networks.
Economic and operational impact
The resolution does not include economic figures on the cost of the infrastructure or access tariffs to the injection point. However, its operational implications are relevant for several market actors:
- For biomethane producers: The existence of a new injection point on the Salamanca-Zamora pipeline expands connection options to the transport network in Castilla y León. Accessing Enagás's transport network is the necessary step to commercialize biomethane at scale and benefit from the support mechanisms for renewable gases in force in Spain.
- For the renewable gas market: Each new enabled injection point reduces the infrastructure bottlenecks that hinder the development of the biomethane sector in Spain. The G-65 measurement station guarantees traceability and control of the injected gas.
- For landowners in Peleas de Abajo: The declaration of public utility enables Enagás Transporte SAU to initiate occupation or easement procedures on affected land. This may involve compensation negotiations or, ultimately, forced expropriation.
- For Enagás Transporte SAU: The authorization allows progress in project execution and expands the capacity to receive renewable gases in its transport network.
Who does it affect?
- Enagás Transporte SAU: Company authorized to build and operate the new infrastructure. Responsible for project execution and land occupation processes.
- Biomethane producers in Castilla y León: Companies or projects that produce biomethane and seek injection points on the natural gas transport network. This new point in Peleas de Abajo (Zamora) may be relevant for facilities located in the vicinity of the Salamanca-Zamora pipeline.
- Landowners in Peleas de Abajo (Zamora): Affected by the declaration of public utility, which enables the occupation of land necessary for the installation.
- Biogas and biomethane project developers: Companies planning new biomethane production plants and evaluating the viability of connection to the existing network.
- Energy advisors and energy transition consultants: Professionals who assist companies in accessing renewable gas infrastructure.
Practical example
An agro-industrial company located in the province of Zamora that manages organic waste and has built a biogas plant needs to connect to the natural gas transport network to commercialize its production as certified biomethane.
Until now, the absence of nearby injection points on the Salamanca-Zamora pipeline could represent a significant logistical and economic obstacle: either transporting the biomethane by other means, or connecting to more distant points with higher infrastructure costs.
With the new position O-12X and measurement station G-65 enabled in Peleas de Abajo, this company can explore direct connection to the Salamanca-Zamora pipeline, reducing the distance of the connection installation and potentially the associated costs. The next step would be to initiate contact with Enagás Transporte SAU to learn about the technical and economic conditions for accessing this new injection point.
What should companies do now?
- Biomethane producers: Evaluate whether your production plant is in the area of influence of the Salamanca-Zamora pipeline and whether the new position O-12X in Peleas de Abajo can be your closest injection point. Contact Enagás Transporte SAU to request information about access conditions.
- Landowners in Peleas de Abajo: Check whether your property is within the area affected by the project. The declaration of public utility enables Enagás to initiate occupation processes. Seek professional advice before receiving any formal notification.
- Biomethane project developers in Castilla y León: Incorporate this new injection point into your analysis of connection viability to the network. Consult the approved execution project to learn about the technical specifications of the installation.
- Energy advisors and consultants: Update your map of available biomethane injection points in Spain with this new node in Zamora. It is relevant information for clients evaluating the viability of biomethane projects in the region.
- All affected parties: Monitor the publication of project execution timelines by Enagás Transporte SAU, as the operational entry into force date of the infrastructure is not specified in the published resolution.
