Biomethane in Segovia: Redexis injects renewable gas into transport network with investment of 50,854 €

Key data

The General Directorate of Energy Policy and Mines has authorized Redexis Infraestructuras, SL to construct and operate a new position on the Segovia Norte pipeline exclusively for biomethane injection. The resolution, published on 26 September 2026 in the BOE (BOE-A-2026-19994), simultaneously grants administrative authorization, approval of the execution project, and declaration of public utility of the facilities.

This type of authorization sets the real pace of energy transition in the gas sector: each new biomethane connection to the transport network is a concrete step toward gas decarbonization in Spain.

What does this regulation establish?

The resolution grants Redexis Infraestructuras three authorizations in a single administrative act:

• Administrative authorization: permission to construct and operate the facility.
• Approval of the execution project: technical validation of the specific design presented.
• Declaration of public utility: recognition that facilitates, if necessary, land occupation and easement processing.

Technically, the installation consists of a 4-inch steel piping 7 meters in length that connects at kilometer point 26+840 of the Segovia Norte pipeline. This new position acts as the entry point for biomethane produced in the area into the primary transport network, operating at a pressure of 80 bar and with a maximum capacity of 2,775 Nm³/h.

The project did not require environmental impact assessment and received no objections during the public information process. The CNMC issued a favorable report in July 2026, clearing the way for the final resolution.

Economic and operational impact

With a budget of 50,854.68 €, this installation is technically modest but strategically relevant. The reduced cost is explained by the short piping length (7 meters) and direct connection to existing infrastructure. However, the operational value is disproportionately greater: it enables biomethane entry into the primary transport network at high pressure (80 bar), which implies regional-scale distribution.

For the gas sector, each biomethane injection point in the transport network means:

• Reduced dependence on fossil natural gas in the mix distributed by that network.
• Generation of new revenue streams for biomethane producers who need access to the transport network.
• Progressive compliance with gas system decarbonization objectives established in European and Spanish regulations.
• Precedent for similar processing at other points in the network managed by Redexis.

Who does it affect?

• Redexis Infraestructuras, SL: directly authorized company. Must execute the project according to the approved design and maintain the facility in operational conditions.
• Biomethane producers in the Carbonero el Mayor (Segovia) area: this infrastructure is the access point to the transport network for anyone producing biomethane in the area.
• Gas transport network operators: must integrate biomethane flows into their management of the Segovia Norte network.
• Municipality of Carbonero el Mayor: territory where the facility is physically located, with the associated declaration of public utility.
• Energy sector companies studying similar biomethane injection projects into the network: this resolution is a reference for processing and requirements.

Practical example

Imagine a biomethane plant located near Carbonero el Mayor that produces renewable gas from agricultural waste. Until now, without a connection point to the transport network, that biomethane could only be distributed locally or by tanker truck, with high logistics costs and limited reach.

With the new position authorized to Redexis at KP 26+840 of the Segovia Norte pipeline, that plant can inject up to 2,775 Nm³/h directly into the transport network at 80 bar. This means immediate access to all consumption points connected to the Segovia Norte pipeline, with the ability to scale distribution without additional proprietary infrastructure. Redexis's investment in the connection (50,854.68 €) is what enables that access: a relatively low entry cost for the impact it generates in the biomethane value chain.

What should companies do now?

1. If you are a biomethane producer in the Segovia area: contact Redexis Infraestructuras to learn about access conditions to the authorized injection point at KP 26+840 of the Segovia Norte pipeline.
2. If you operate in the gas sector and are studying similar projects: analyze this resolution as a processing model. The process was agile: no objections in public information and favorable CNMC report in July 2026 for a resolution published in September.
3. If you are an investor or advisor in renewable energy: identify other points in the transport network where biomethane injection is not yet enabled. Authorizations of this type have relatively low project costs (in this case, 50,854.68 €) and high strategic value.
4. If you manage regulatory compliance in an energy company: review whether your company has obligations to integrate renewable gas and whether projects like this can contribute to their compliance.
5. Consult the complete resolution in the BOE (BOE-A-2026-19994) to verify the exact technical and administrative conditions of the authorization.
