The satellite biogas plants related to Suomen Lantakaasu Oy’s Ylä-Savo biogas project, built by Doranova, have progressed according to schedule. The project has now entered the process installation phase, which will be completed during the winter. Commissioning of the plants will begin in early summer 2026.
Doranova Oy is involved in delivering one of the most significant biogas investments in Finland. Suomen Lantakaasu Oy’s Ylä-Savo project complex consists of a central plant in Kiuruvesi and two satellite plants located in Lapinlahti and Nurmes. Doranova has been responsible for the design of the satellite plants, the permitting process, as well as their construction and commissioning.
The project represents a modern hybrid production model in which the Lapinlahti and Nurmes satellite plants produce compressed biogas (CBG). The CBG is transported to the central plant in Kiuruvesi, where the biogas is liquefied into LBG and delivered for end use. The project serves a broad agricultural network, involving more than 100 farms.
The Lapinlahti and Nurmes plants are identical facilities, each permitted to receive 34,500 tonnes of feedstock per year and to produce 10 GWh of compressed biomethane annually. The main feedstock is liquid manure, with solid manures and feed residues generated as feeding losses also utilized. The plants are equipped with post-hygienisation, ensuring the safety of the nutrient products. To optimize gas production, the process heat required by the biogas plants is generated by wood-chip-fired heating plants.
Doranova’s Business Area Director, Mikko Saalasti, notes that the cooperation began as early as the design and environmental permitting phase in 2023:
“Doranova has had the honor of being involved in the design and environmental permitting processes of the satellite plants since 2023. Earthworks were able to start as early as the winter of 2025, which made it possible to complete the tank structures and process buildings well ahead of the winter season. During the winter of 2025–2026, process equipment as well as electrical and automation systems will be installed. The projects have progressed according to schedule, and around the summer period we will be able to begin commissioning at both sites.”
Saalasti emphasizes the importance of the projects both for Doranova and for the Finnish biogas sector:
“The Lantakaasu projects will account for a significant share of Doranova’s workload in 2025–2026. At the same time, Lantakaasu is rapidly developing into a key player in the Finnish biogas industry. These projects therefore represent an excellent opportunity for Doranova to demonstrate our expertise,” Saalasti concludes.
