Major Investments in Polish Biomethane Become a Reality. Biorig Will Invest over PLN 1.5 Billion in a Platform Targeting 1 TWh/ Year

(Solarig) • Solarig, a worldwide leader in sustainable energy solutions with a proven project record of 20 GW, is expanding its biomethane operations in Poland through its renewable gases division, Biorig.

WARSAW, December 15th – 2025. Solarig, through its green division, Biorig, will invest PLN 1.5 billion in the Polish biomethane market by creating a major platform with the capacity to produce 1 TWh/y — enough to power 400,000 average Polish households.

The Spanish company aims to be a leader in this emerging segment of the local economy. Especially, since Poland has significant potential for biomethane production, which, according to the Polish Economic Institute (PIE), could reach as much as 8 billion m³ per year, corresponding to 46% of the country’s natural gas demand. In the long term – by 2050 – it may increase to even 13 billion m³ (Gas for Climate data), which would place Poland in 5th place in the EU in terms of production capacity.

Biorig also chose this region due to its large livestock base, which offers potential for sustainable feedstock. Poland has the second-highest number of farms in the EU after Romania, with 1.3 million agricultural holdings. The country also has nearly 5.9 million hectares of cultivated land devoted to cereals, as well as robust and varied poultry, cattle and swine farming sectors. These conditions create an ideal landscape for Biorig’s green investments, which are deeply rooted in the rural environment and integrated with the agricultural sector, relying on manure, slurry and various agricultural by-products, including straw. Biorig’s comprehensive model optimizes waste management from the primary sector, reducing environmental contamination of soils through nitrification.

Biorig’s growth strategy in Poland will be centered on collaboration with local developers and suppliers who share the company’s technical and environmental vision. This will be achieved through the acquisition of brownfield projects that are ready to build (Rtb). The company will then be able to further develop these initiatives by integrating its experience in the construction, management and operation of biomethane plants in Europe. This approach will be complemented by greenfield developments for new facilities.

Announcements regarding business plans for Poland are part of the development strategy of the Solarig Group, representing a company’s commitment to Poland’s energy transition.

By launching Biorig’s operations in Poland, Solarig is broadening its contribution to the energy transition beyond renewable electricity, and adds a focus on renewable gases that amplifies its current portfolio under development of around 1.5 GW of energy storage assets (BESS) and PV projects. Meanwhile, Biorig strengthens its position as one of Europe’s leading biomethane developers and producers, with over 60 facilities under development across Spain, Italy, and now Poland.

Altogether, this portfolio will generate around 5 TWh/year of renewable energy, making a decisive contribution to reducing Europe’s dependence on fossil natural gas and improving waste management in key regions of the continent.

– Poland represents a strategic opportunity due to the great potential of its market: this is a key moment, thanks to regulatory momentum that encourages the installation of biomethane plants—energy infrastructures essential for reducing dependence on fossil fuels and efficiently managing organic waste for recovery as biofertilizers. These are solid foundations on which to establish ourselves as a leading international player in the biomethane market. We are excited to contribute to the sector’s development with a model successfully tested in Spain and Italy, adapted to the local context – explained Piotr Tomasz Kosior, Country Manager Biorig Poland.

Biorig’s plan is to develop around 20 biomethane plants located across several regions in Poland, including Zachodniopomorskie (West Pomeranian), Wielkopolskie (Greater Poland), Dolnośląskie (Lower Silesian), Ślaskie (Silesian), Lubelskie (Lublin), Mazowieckie (Masovian), and Podlaskie (Podlaskie). Biomethane produced there will be supplied to industrial customers, particularly energy-intensive manufacturers seeking cost-competitive green energy, through gas grid contracts for pipeline delivery and long-term purchase agreements (BPAs) to assure long-term income.

Solarig develops, finances, builds, and operates infrastructures for the energy transition. The company currently operates over 15 GW of renewable assets and has a project portfolio exceeding 20 GW across 12 countries. It promotes global decarbonization wherever it operates through renewable energy, green gases, and sustainable fuels. Headquartered in Madrid (Spain), Solarig has a strong presence in Europe, Central and South America, Japan, and Australia.

Solarig initiated its operations in Poland in 2023. Since then, a fully capable local structure was established, which has since taken over origination activities. As a result of both the in-house efforts and co-development partnership, Solarig’s portfolio in Poland currently includes over 300 MW of PV assets and over 1,1 GW of BESS projects.

Biorig is Solarig’s biomethane production division. It was created to provide innovative solutions in the field of renewable gases, such as biomethane. Its activity focuses on the management of agricultural and livestock organic feedstock for transformation into renewable gases and on promoting projects that foster energy transition and circular economy.
