Biomethane Monetary Incentive Program

In 2015, pursuant to California Public Utilities Commission (CPUC) Decision 15-06-029, the CPUC adopted the biomethane interconnector monetary incentive program2. The objective of the program is to encourage the development of biomethane projects that are interconnected to the utilities’ gas pipeline systems. The initial incentive program contributed up to 50 percent of the interconnection costs, with a cap of $1.5 million per project. The statewide funding for the monetary incentive program is capped at $40 million.
On September 24, 2016, the interconnector monetary incentive program was modified when Gov. Jerry Brown signed AB 2313 into law.  The senate bill increased the maximum funding for this incentive program to up to $3 million per project. This bill also allows for dairy cluster projects, defined as three or more dairies in close proximity, to include gathering line costs as a qualifying interconnection expense, and increases the maximum incentive for these projects to $5 million per project.
The monetary incentive is available to eligible Biomethane Interconnectors until December 31, 2021, or until the program has exhausted its $40 million cap.  The program is described in detail in SoCalGas’ Rule 39 Section A.3.a.
