Finnish gas company Gasum has sold its biogas upgrading unit in Lahti to energy company Nevel, under an arrangement that sees Gasum continue to purchase all upgraded biogas from the plant under a long-term agreement.
The transaction took effect on 23 June 2026. Nevel had previously supplied raw biogas to Gasum's upgrading unit from its adjacent Lahti biogas plant, making the acquisition a consolidation of what had been a split operation across two owners.
Under the new structure, Nevel takes ownership of the upgrading unit and will manage the full value chain from raw biogas production through to upgrading. Gasum will purchase the resulting biomethane and feed it into the gas network for sale to customers. The companies said the change will have no impact on customers.
Nevel said it plans to invest in renewing the plant's operations, with the aim of improving production efficiency and expanding upgrading capacity. For Gasum, purchasing upgraded biogas directly simplifies its procurement process.
Nevel's Kujala biogas plant in Lahti processes around 90,000 tonnes of biodegradable waste, sewage sludge and industrial side streams annually, producing approximately 50 GWh of biogas per year. The plant was originally built by Labio Oy in 2014, with Gasum constructing the upgrading unit and gas grid connection at the same time. Nevel acquired the biogas plant from Labio in 2025 and has now added the upgrading unit to complete its ownership of the site.
Gasum retains ownership of the gas grid connection and associated container unloading station.
