Project Description

In December of 2017, the California Public Utilities Commission (CPUC) established a new program that aims to reduce methane emissions from manure generated at dairies. The CPUC said the pilot program will incentivize at least five projects where dairy digesters produce renewable natural gas (RNG) from manure.

The program was adopted pursuant to SB 1383, which established a goal to reduce California’s methane emissions 40 percent by 2030. As part of this goal, the bill authorizes funding of the dairy biomethane pilot projects to demonstrate interconnection to the gas pipeline system. The pipeline infrastructure is needed to inject RNG into the utilities’ natural gas distribution system.
