Below we explain the different types of services we offer third-party users for connection to the Enagás transmission network.
A direct line is a connection between an Enagás transmission network high-pressure pipeline and a pipeline that directly supplies a qualified consumer.
This service allows gas to be supplied at a maximum pressure of 72/80 bar, which is a particularly important technical advantage for some industrial processes, as well as for electricity generation (cogeneration), as it avoids the post-compression of gas.
Enagás places its measuring station, where the metering of natural gas consumption is performed, at the disposal of the end customer. In this case, Enagás is responsible for all periodic meter verifications and calibrations as required under the Rules for the Technical Management of the System (NGTS).
At Enagás, qualified consumers can make use of our experience in the construction and maintenance of transmission pipelines. If you are interested in constructing a Direct Line, please do not hesitate to contact us.
To connect to our transmission network, you must complete the connection request form available on this page and Enagás will provide a response on the viability of the connection within 40 working days. If feasible, the infrastructure connection contract and the measurement protocol will be signed before commencing the connection project; both of these documents are available on this page.
Once the connection facilities have been completed and the commissioning certificate has been obtained, the launch of the facilities will be carried out in coordination with Enagás.

With this service, it is possible to contract the construction or enlargement of a physical connection with a transmission pipeline with an Enagás pipeline.
To do so, the owner of the gas transmission pipeline must complete a connection request using the template available on this page. Once received, Enagás will have 40 business days to provide a response on the viability of the connection. If feasible, the infrastructure connection contract and connection management manual will be signed before commencing the connection project; both of these documents are available on this page.
Once the connection facilities have been completed and the commissioning certificate has been obtained, the launch of the facilities will be carried out in coordination with Enagás. The following requirements must be met before the gas pipeline can be commissioned:
Enagás, as the leading natural gas transmission company in Spain, operates more than 45 transmission network connections (PCTT) throughout its network.

The decarbonisation targets set by the European Union have accelerated the pace of promotion and development of renewable gases, including biomethane. In Spain, the update of the National Integrated Energy and Climate Plan 2023-2030 (PNIEC) has a specific measure (1.15) for the development of biogas and biomethane, which establishes specific objectives for the promotion, production and consumption of these energy solutions.
In this context, Enagás is working to adapt its transmission infrastructure to facilitate the injection of renewable gases into the network and, through the Green Link service, to lay the foundations for the future injection of renewable energies into the system. The Green Link service allows the different agents in the Gas System to request connection of their biomethane and/or hydrogen production facilities to the transmission network managed by Enagás.
Through Green Link, Gas System agents can contract modular solutions tailored to their needs, deadlines and budgets. It is a comprehensive and innovative solution that covers the entire infrastructure life cycle (from design to decommissioning). Moreover, it features a commercialisation model that is active, agile, simple and transparent. It also complies with the high-quality standards guaranteed by Enagás.
How to contract a biomethane connection service
Companies interested in applying for the biomethane connection service must register before accessing the platform set up for this purpose.
The company interested in connecting to the transmission network will find instructions on this platform on how to pay the costs of drawing up the connection quotation. Said company may also request additional information from the transmission system prior to the application for connection. In the event of a viable connection request, the applicant company must sign the documentation provided by Enagás to begin the connection process, within a maximum period of 60 business days from the date of reply to the request, and pay 10% of the connection budget, as well as providing the requested documentation.
How to contract a hydrogen connection service
Companies interested in applying for the hydrogen connection service must fill out the following form.
In compliance with the Spanish Royal Decree-Law 14/2022, of 1 August, on economic sustainability measures in the field of transport, grants and study aids, as well as measures for energy saving, efficiency and reduction of energy dependence on natural gas, Enagás will provide a response on the technical-financial viability of the requested biomethane and/or hydrogen connection, as well as the contract models, within a maximum period of 40 business days.
