Two projects in the city of Albacete will see Naturgy, through its distribution subsidiary Nedgia, inject 34 GWh of renewable biomethane per annum into the city’s gas network, as part of the “Albacete Green Energy” strategy.


With the support of the different public authorities (City Council, Provincial Council and Regional Government of Castilla-La Mancha) and private enterprise, the City Council has submitted 14 projects forming part of the Albacete Green Energy strategy for funding from the European Union Next Generation fund. These initiatives have a common goal: to help the city grow, and to build a future with greater opportunities and quality of life by promoting an integrated circular economy.

Thanks to this roadmap for the future, Albacete will become the first city in Spain to avail of the biomethane produced from water treatment at the Wastewater Treatment Plant (WWTP) and waste treatment from the Municipal Solid Waste Treatment Centre (CTRU).

To this end, more than 6 kilometres of pipeline will be built to enable the city’s distribution network to convey the 34 GWh of renewable gas to be generated each year in these two initiatives. This is equivalent to the consumption of 6,800 homes in the city of Albacete. Moreover, CO2 emissions will be reduced by 8,250 tonnes, equivalent to planting around 390,000 trees.

Pioneering initiatives

The first of the projects, which will be undertaken by Aguas de Albacete and Naturgy at the city’s WWTP, will produce 16 GWh of biomethane per annum for consumption in the different offices and buildings of Albacete City Council. The second project, to be undertaken by the Albacete Provincial Council at the Municipal Solid Waste Treatment Centre (CTRU), will see the production of 18 GWh of biomethane per year, as well as 4,000 tonnes per annum of high added value fertilisers. This project also aims to increase waste recycling by recovering reject streams and a greater quantity of glass, and by producing recycled plastic to generate renewable energy in the form of electricity and heat to supply local businesses.

For Naturgy, participation in this project is further consolidation of the company’s commitment to the decarbonisation of the gas network and the circular economy. The progressive incorporation of renewable gases, such as biomethane, or hydrogen in the future, into the Spanish gas system will play a key role in achieving 2030 and 2050 decarbonisation targets. Moreover, injecting renewable gas into gas distribution infrastructures is the most efficient and cost-effective way to decarbonise households, as well as all grid-connected economic sectors.
