Nedgia’s network is adding a new green gas plant in O Porriño (Pontevedra), another step towards bringing renewable energy to homes and businesses using existing gas infrastructure.
This new facility has an annual feed-in capacity of 38 GWh, enough to meet the energy needs of more than 7,400 homes. It will also prevent the emission of around 6,900 tonnes of CO₂ per year, helping to reduce the carbon footprint and support the transition to a more sustainable energy model.
What is green gas?
Green gas, or biomethane, is a renewable energy source produced from organic waste that can be distributed via the existing gas network. Consumers can therefore benefit from increasingly sustainable energy without having to make any changes to their gas installations or appliances.
More renewable gas for households
With the addition of O Porriño, there are now 18 green gas plants connected to the Nedgia network, with a combined capacity of 569 GWh per year, equivalent to the consumption of more than 100,000 households.
This progress reinforces Nedgia’s commitment to the development of renewable gases and demonstrates how distribution networks can play a key role in the decarbonisation of energy consumption, enabling more and more households to access renewable energy safely and efficiently, whilst making use of existing infrastructure.
Driving the energy transition
Commissioning new biomethane plants, such as O Porriño, enables us to continue moving towards a more sustainable energy model, promoting the use of local resources and helping to reduce emissions. Another step towards bringing green gas to more homes and contributing to a low-emission energy future.
