The future of renewable energy is often shaped not just by innovation but also by smart partnerships. On September 8, 2025, Anaergia announced that it has signed an agreement to sell the Riverside Bioenergy facility in California, marking a significant step in its capital light growth strategy. While the deal value has not been disclosed, this transaction highlights how strategic collaboration can unlock climate solutions while reducing financial exposure.

The Riverside Bioenergy facility represents a cornerstone for the City of Riverside’s sustainability efforts, particularly in meeting the state’s SB1383 organic waste recycling regulations. The facility, located at the Riverside Water Quality Control Plant, will be upgraded to process municipal organic waste into renewable natural gas (RNG). By diverting waste from landfills and transforming it into clean energy, this project will substantially cut the carbon footprint of Riverside’s water treatment operations. The initiative demonstrates how municipal partnerships with clean-tech companies can turn regulatory compliance into long-term environmental value.

Although ownership of the facility will be transferred to a developer backed by institutional investors, Anaergia’s presence will remain integral. Through its affiliate Anaergia Technologies, the company will deliver EPC services, including advanced biogas conditioning, upgrading systems, and organic feedstock processing scheduled for 2026 and 2027. Additionally, Anaergia Services will provide long-term operations and maintenance, ensuring the facility operates efficiently once construction is complete. A separate technology supply contract worth approximately C$13 million with the City of Riverside further deepens Anaergia’s role in advancing local energy infrastructure.

The financial model of the Riverside Bioenergy facility underscores the growing importance of policy-backed clean energy demand. Revenue will be generated through the sale of RNG into the gas grid under long-term fixed-price contracts, supported by California’s SB 1440 mandate. With utilities required to procure at least 12% RNG by 2030, this framework secures reliable offtake while ensuring the project contributes to statewide emission reductions. For Anaergia, this approach reflects a broader shift—prioritizing flexibility and strategic partnerships while advancing impactful climate solutions.

Anaergia’s Riverside deal highlights a model where capital efficiency meets environmental ambition. As the project progresses, it will serve as a case study in how municipalities, investors, and technology providers can work together to drive the transition toward cleaner energy systems.
