The Three Seas Initiative Investment Fund (3SIIF) has invested in Bioforce, Estonia’s largest biomethane producer, operator and distributor, to support the company’s expansion into Poland and Latvia and accelerate the growth of renewable gas production across Central and Eastern Europe.
Bioforce currently holds an estimated 40 percent share of Estonia’s biomethane market and operates three production facilities in the country. A fourth plant is in the initial commissioning phase, bringing the company’s combined production capacity to more than 250 GWh of biomethane annually.

The investment will provide Bioforce with capital to develop a pipeline of greenfield biomethane projects in Poland and the Baltic region. The planned expansion is expected to increase the company’s production capacity fourfold to approximately 1 TWh by 2032.
As part of its growth strategy, Bioforce plans to establish a presence in Poland by developing new biomethane facilities, supported by the funding from 3SIIF. The company has already recruited a local management team to oversee its Polish operations and intends to further strengthen its presence in the market.
The investment provides 3SIIF with exposure to the growing biomethane sector through an integrated platform spanning production, operations, distribution, cross-border trading and industrial offtake. The fund said the expansion of renewable gas capacity is expected to support the energy transition in Central and Eastern Europe by reducing dependence on imported natural gas and diversifying regional energy supplies.
The Bioforce transaction marks the sixth investment by the Three Seas Initiative Investment Fund. Previous investments include Polish locomotive leasing company Cargounit, Estonia-based Greenergy Data Centers, renewable energy developer Enery, Bulgarian port operator BMF Port Burgas, and Polish renewable energy developer R.Power.
Henry Uljas, Chairman of the Management Group at Bioforce, described the transaction as the largest investment to date in biomethane production in the Baltic states. He said the funding would enable the company to expand production capacity in Estonia while accelerating its entry into Poland and other Baltic markets.
According to Uljas, Bioforce aims to begin construction of its first biomethane plant in Poland in 2027 and plans to build and commission at least 10 biomethane facilities across the country over the following five years, positioning the company for significant regional growth while supporting energy security through increased domestic renewable gas production.
