SB 919 California Senate · 2025-2026 Regular Session

Biomethane monetary incentive program.

Summary
The California Global Warming Solutions Act of 2006 designates the State Air Resources Board as the state agency charged with monitoring and regulating sources of emissions of greenhouse gases. The act authorizes the state board to include the use of market-based compliance mechanisms in regulating those emissions. The implementing regulations adopted by the state board provide for the direct allocation of greenhouse gas allowances to electrical corporations and gas corporations pursuant to a market-based compliance mechanism. Existing law vests the Public Utilities Commission with regulatory authority over public utilities, including gas corporations. Existing law requires the commission to consider options to promote the in-state production and distribution of biomethane, and that facilitate the development of a variety of sources of in-state biomethane. The commission has adopted 2 decisions implementing these requirements, the 2nd of which adopted a 5-year monetary incentive program effective June 11, 2015, for biomethane projects. Existing law requires the commission to modify the biomethane monetary incentive program in specified respects and to extend the program, as modified, until December 31, 2026, or until all available program funds are expended, whichever occurs first. This bill would require the commission to extend the biomethane monetary incentive program until December 31, 2030. The bill would authorize the commission to authorize additional funding of $50,000,000 for the program, of which no more than $10,000,000 would be authorized for dairy biomethane projects, using the revenues, including any accrued interest, received by a gas corporation as a result of the direct allocation of greenhouse gas allowances provided to gas corporations as part of the above-described market-based compliance mechanism. Under existing law, a violation of the Public Utilities Act or an order, decision, rule, direction, demand, or requirement of the commission is a crime. Because the provisions of this bill would be part of the act and because a violation of a commission action implementing its requirements would be a crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

What changed between versions

03/05/26 - Amended Senate 04/28/26 - Amended Senate · 5 edits · Apr 28, 2026
MODERATE
The April 28 amendment to SB 919 removes a separate section that required the Public Utilities Commission to allow rate recovery of biomethane interconnection costs by June 1, 2026, and instead consolidates all provisions into a single amendment to Section 399.19. The bill now specifies a concrete funding amount of $50 million (capped at $10 million for dairy biomethane projects) for the incentive program, extends the program's sunset date from January 1, 2027 to January 1, 2031, and adds legislative findings referencing the PUC's March 2026 proposed decision declining to ratebase interconnection costs.
Scope change
The bill's scope narrowed by removing the standalone Section 784.2 amendment (which imposed a June 1, 2026 deadline for rate recovery), while its funding scope became more specific with the $50 million cap and $10 million dairy sub-cap. The effective period of the law was extended by four years.
REQUIREMENT

The entire amendment to Section 784.2 of the Public Utilities Code was removed. That section had required the commission to allow recovery in rates of biomethane infrastructure investment costs on or before June 1, 2026. Rate recovery is now governed solely by Section 399.19(4)(A), which takes effect on and after January 1, 2027.

FISCAL

The bill now specifies that the commission may authorize additional funding of $50,000,000 for the biomethane monetary incentive program, with a cap of no more than $10,000,000 for dairy biomethane projects. The prior version authorized 'additional funding' without specifying an amount.

TIMELINE

The section's sunset date was extended from January 1, 2027 to January 1, 2031, giving the law four additional years of effect.

SCOPE

The language 'or until all available program funds are expended, whichever occurs first' was removed from the program extension provision. The program is now guaranteed to run until December 31, 2030 regardless of whether funds are exhausted earlier.

DEFINITION

Two new legislative findings were added: one referencing the PUC's March 6, 2026 Proposed Decision in Rulemaking 13-02-008 (which declines to ratebase biomethane interconnection costs but directs gas corporations to host a cost-reduction workshop and authorizes them to file ratebasing applications), and another stating the commission should act expeditiously on ratebasing if it recognizes ratepayer savings and greater likelihood of meeting 2030 methane reduction goals.
