The distribution networks of Nedgia, the Naturgy group’s gas distributor, have channeled more than 170 GWh of biomethane during 2025, which represents an increase of 53% compared to the previous year, consolidating itself as a strategic asset for the promotion of green gas in Spain.
The evolution recorded in 2025 confirms the upward path begun in previous years and underpins biomethane as a key energy vector in promoting a competitive energy transition. According to the information provided by the company itself, “this growth has been possible thanks to the technological maturation of biomethane and the progressive incorporation of new production plants into the Nedgia network.”
“Biomethane is already a reality in the Spanish energy system and our networks are demonstrating that they can integrate it immediately and efficiently. At Nedgia we are putting the infrastructure at the service of the energy transition, facilitating green gas of local origin to reach homes, industries and businesses, and contribute directly to the reduction of emissions and energy independence,” says Raúl Suárez, CEO of Nedgia.
Reduction of CO2 emissions
The distributor already has 14 connected facilities that injected 170 GWh of biomethane last year, an amount equivalent to the annual consumption of more than 33,000 homes. This renewable energy made it possible to reduce emissions by more than 34,000 tons of CO2.
This strong push for green gas will continue in the coming months, since Nedgia has 98 projects in its portfolio with a signed contract to inject green gas into the network, which could total a volume greater than 5.8 TWh/year, a figure equivalent to the annual consumption of 1.1 million homes. According to Naturgy’s forecasts, there will be fourteen projects that will begin to inject green gas into the network throughout 2026.
A key vector for decarbonization
Biomethane is a gas of renewable origin obtained from the treatment of very different types of waste. Thanks to the connection to the grid of the plants that produce it, this green gas can be used in the same uses as conventional natural gas, contributing to reducing CO₂ emissions and reinforcing energy independence with an indigenous and sustainable source.
The integration of biomethane into the gas network allows immediate progress in the decarbonization of sectors that are difficult to electrify, such as industry or heavy transportation, and complements other renewable solutions within an integrated technological approach.
According to a report from the Spanish Gas Association (SEDIGAS), Spain has the technical potential to produce 163 TWh per year of biomethane. This capacity represents approximately 45% of national natural gas consumption, which would cover 100% of residential and commercial demand.
Nedgia is playing a strategic role in promoting the distribution of so-called green gas through a network that already has more than 60,000 kilometers and with which it could immediately deliver renewable gas to more than 5.5 million supply points distributed in 1,222 municipalities, serving homes, companies and industries throughout the national territory.
According to Nedgia, the good figures for the previous year confirm that biomethane is no longer a solution for the future, but rather a present reality, with a tangible impact on the reduction of emissions and the transformation of the energy system. In any case, this energy still requires impulse mechanisms that allow it to unfold its enormous potential, as is already happening in other countries around Europe.
