CPUC Issues Proposed Decision on Voluntary RNG Tariff

The CPUC has issued a Proposed Decision that would adopt a voluntary tariff for customers of SoCalGas and SDG&E to choose to purchase biomethane.  The tariff requires that at least half of the biomethane purchased by the utilities is generated in California and half of that portion must come from sources other than landfill gas to help California meet is Short-Lived Climate Pollutant and waste reduction goals.  The tariff will include biomethane generate from biomass conversion (gasification and pyrolysis) as well as the biomethane from anaerobic digestion of organic waste.  The Proposed Decision would approve the voluntary tariff as a three-year pilot program and will then assess whether to make it permanent or replace with a biomethane procurement program.
