Anaergia’s SoCal biomethane facility in California begins deliveries under SB 1440 contract to Southwest Gas

June 10, 2026. Anaergia Inc. has begun deliveries to Southwest Gas Corporation’s distribution system. This marks the first delivery of renewable natural gas (RNG) in California under the state’s Biomethane Procurement Program.

The project received conditional approval by the California Public Utilities Commission on March 19, 2026 and commenced RNG delivery after satisfying the CPUC conditions, demonstrating SB 1440’s effectiveness in enabling commercial-scale RNG projects that meet utility safety and quality standards.

“As the first facility to deliver renewable natural gas under California’s Biomethane Procurement Program, the SoCal Biomethane facility proves that organic waste can be transformed into a reliable and renewable fuel source at scale,” said Assaf Onn, CEO of Anaergia. “By integrating with existing wastewater infrastructure, we are delivering immediate value to customers while establishing a replicable blueprint for communities across the state.”

The SoCal Biomethane facility, located at the Victor Valley Wastewater Reclamation Authority in Victorville, co-digests municipal wastewater solids and diverted organic waste sourced across Southern California, upgrading resulting biogas to pipeline-quality RNG that complies with Southwest Gas’ California tariff. The facility can process up to 104,000 tons of organic waste annually and has the potential to reduce greenhouse gas emissions by up to 31,710 metric tons of CO2-equivalent per year.

“This agreement marks an important step in Southwest Gas’ efforts to responsibly integrate RNG into our supply portfolio,” said Justin Brown, President and CEO of Southwest Gas. “Projects like this show what’s possible, delivering tangible environmental benefits for our communities while supporting the energy needs of our customers.”

Anaergia worked with commercial partner Anew Climate, which markets RNG from the SoCal Biomethane facility and supports utility offtake, carbon intensity compliance, and physical delivery and scheduling as a Core Transport Agent in California. The collaboration and this contract establish a model for SB 1440 implementation and a replicable pathway for future biomethane projects across the state.

“We’re pleased to support this project as it moves into active delivery under SB 1440,” said Andy Brosnan, President of Low Carbon Fuels at Anew Climate. “This work reflects the coordination required across industry and regulators to bring renewable natural gas projects online, and the experience gained here will help inform future development across California and in other regions pursuing methane reduction, grid reliability, and expanded renewable energy supply.”

SB 1440 requires investor-owned utilities in California to procure RNG derived from landfill-diverted organic waste, with statewide targets indicating the need for many similar facilities by 2035. The SoCal Biomethane project’s transition to active delivery provides an operational and regulatory template to accelerate broader deployment.
