Biogen supports customers and partners through flexible energy offtake agreements that provide long‑term certainty, stable pricing and access to low‑carbon energy generated from organic waste. As a leading UK anaerobic digestion operator, Biogen offers tailored solutions for both electricity and biomethane offtake, helping organisations meet commercial and sustainability objectives.

Electricity produced at Biogen’s AD facilities is sold through Power Purchase Agreements (PPAs). A PPA is a contract under which renewable electricity is supplied to an offtaker, typically an energy supplier or large end user, at agreed commercial terms. These agreements provide predictable revenues for generators while giving offtakers access to reliable, renewable power that supports decarbonisation targets and energy security.

Biogen also produces biomethane, which is exported to the gas grid through Gas Purchase Agreements (GPAs). GPAs govern the sale of renewable gas to an offtaker and play a key role in reducing the carbon intensity of gas supply. Biomethane produced through anaerobic digestion is fully traceable and compliant with UK regulatory standards, making it an attractive option for organisations seeking lower‑carbon alternatives to natural gas.

Both PPAs and GPAs can be structured to suit different commercial requirements, whether customers are looking for long‑term fixed pricing, market‑linked arrangements or certificates to support carbon reporting. Biogen works closely with offtake partners to ensure contracts are clear, transparent and aligned with operational realities.

Through its energy offtake agreements, Biogen helps turn food and organic waste into dependable, low‑carbon energy, supporting the transition to a more sustainable UK energy system while delivering value for customers and partners alike.

Biogen works closely with businesses to structure agreements that align with operational needs, annual energy consumption and long‑term carbon‑reduction strategies. Throughout the duration of the agreement, customers receive transparent reporting and recognised certification, demonstrating the renewable origin of their energy and providing a robust foundation for compliance, audit and sustainability reporting.

By sourcing energy directly from Biogen, customers actively support the circular economy—helping to convert both food waste and agricultural feedstocks into valuable, low‑carbon energy that powers UK businesses, homes and industry. These long‑term arrangements provide dependable renewable energy while contributing to a cleaner, more resilient energy future.

Our long‑term offtake agreements give organisations certainty, transparency and a direct route to certified renewable energy. By structuring contracts around each customer’s operational and sustainability priorities, we deliver stable pricing, full traceability and dependable access to biomethane or green electricity—supporting real progress toward net‑zero goals and a more resilient energy future.
