How to connect to our transmission network

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:

• A commissioning certificate for the transmission pipeline must be obtained
• The new facility must be registered in the computer systems of the Technical Manager of the System
• The gas in the pipeline must have been acquired in accordance with the regulations

Enagás, as the leading natural gas transmission company in Spain, operates more than 45 transmission network connections (PCTT) throughout its network.

With this service, distributors can contract the construction or enlargement of a physical connection between a distribution network and an Enagás gas pipeline.

To do so, the distributor must submit 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:

• A commissioning certificate for the distribution network must be obtained
• The new facility must be registered in the computer systems of the Technical Manager of the System
• The gas in the network must be provided by a shipper. Please refer to the procedure for filling distribution networks, which is available on this page.

The decarbonisation targets set by the European Union have accelerated the pace of promotion and development of renewable gases, including biomethane.

At national level, the Integrated National Energy and Climate Plan 2021-2030 (PNIEC) devotes Measure 1.8 to the promotion of renewable gases and sets a biogas annual production target of 10.41 TWh by 2030, including a saving of some 2.1 million tonnes of CO₂. The Plan refers to the availability of different types of renewable gases such as –primarily but not exclusively– biogas, biomethane and renewable hydrogen (both in terms of the resource used and the energy used in the production process). The measure provides that the penetration of renewable gas, including biogas, biomethane, renewable hydrogen and others, will be encouraged through the approval of specific plans.

In this context, Enagás is working to adapt its transmission infrastructure to facilitate the injection of biomethane into the network and, through the Green Link service, to lay the foundations for the future injection of renewable hydrogen into the system. The Green Link service allows the different agents in the Gas System to request connection of their biomethane 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 marketing model that is active, agile, simple and transparent and offers payment flexibility with different contracting models. It also complies with the high quality standards guaranteed by Enagás..
