Spanish biomass power producer Magnon generated over 1,240 GWh of renewable electricity in 2025, enough to meet the annual power needs of nearly one million people, the company said on Wednesday, Renewables Now reported.
Most of the output came from Andalusia in southern Spain, where Magnon operates five biomass-fired plants that produced close to 805 GWh during the year. Two facilities in Castile-La Mancha generated more than 310 GWh, while a plant in Extremadura contributed over 125 GWh.
Magnon, which identifies itself as Spain’s largest manager of agroforestry biomass, reported handling more than 1.5 million tonnes of sustainable biomass in 2025—an increase of nearly 10% compared with 2024. The material is sourced primarily from agricultural residues and forestry by-products, helping support rural jobs and local supply chains.
The company is also progressing projects to utilise biogenic carbon dioxide produced at its facilities. Using biomass plants in Huelva, Puertollano and Merida, Magnon is developing an energy hub focused on converting biogenic CO2 into renewable fuels such as e-methanol by combining it with green hydrogen. One of these initiatives involves Dutch company Power2X and its green hydrogen venture, ErasmoP2X.
Magnon operates as the renewable energy arm of Spanish pulp producer Ence Group, which generates more than four million tonnes of biogenic CO2 each year.
