SB 453 directs the California Public Utilities Commission (PUC) to collect status reports from each electrical corporation on awarded and unallocated Microgrid Incentive Program funds and to review whether further action is needed to advance microgrid deployment. If the PUC finds additional steps are warranted, it must consider using a third‑party administrator and require unallocated funds (collected on or before January 1, 2026) to be targeted to areas that have experienced two or more deenergization events, with priority for vulnerable populations and critical community infrastructure.
The bill sets clear deadlines for reporting and a hard stop for reallocations: utilities must provide fund-status updates by January 15, 2026, and any unallocated funds remaining on January 1, 2027, must be returned to ratepayers as bill credits. SB 453 also clarifies that the PUC cannot impose new charges on ratepayers to implement these measures and defines key terms used for prioritization.
At a Glance
What It Does
The bill requires electrical corporations to report the status of Microgrid Incentive Program funds to the PUC by January 15, 2026, and directs the PUC to review and, if needed, reallocate unspent funds collected on or before January 1, 2026. The PUC must consider third‑party administration and prioritize funds to areas with two or more deenergization events, vulnerable populations, and critical community infrastructure; leftover funds on January 1, 2027, must be returned as bill credits.
Who It Affects
Investor‑owned utilities and other electrical corporations that collected Microgrid Incentive Program funds, the PUC (responsible for review and any reallocation), potential third‑party program administrators, and customers in repeatedly deenergized areas—including medically dependent residents and operators of community‑critical facilities.
Why It Matters
The bill forces a near‑term accounting of microgrid program funds and creates a pathway to redeploy dormant dollars to populations most at risk from public safety power shutoffs and other deenergization events. It also imposes a firm sunset for reallocations, which affects whether unspent funds will be used for resilience projects or returned to ratepayers.

What This Bill Actually Does
SB 453 inserts a narrowly focused set of duties into the Public Utilities Code to ensure the Microgrid Incentive Program money collected by utilities is either put to work for resilience projects or returned to customers. First, each electrical corporation must report to the PUC by January 15, 2026, showing how much of the Microgrid Incentive Program funds have been awarded and how much remain unallocated.
The statute ties the PUC’s review to monies collected on or before January 1, 2026, so the analysis is backward‑looking to the pot of funds available up to that date.
If the PUC concludes that additional steps are needed to advance deployment using those collected funds, it must take two concrete actions. One, it must consider appointing a third‑party administrator to run the program for that utility—this is a procurement and governance option designed to overcome utility capacity or conflict issues.
Two, the PUC must direct that remaining unallocated funds be deployed to areas with two or more deenergization events, giving priority to vulnerable populations (including people who depend on electric medical devices or refrigerated medication) and to customers that operate critical community infrastructure that supports resiliency during outages.The bill limits the PUC’s authority in two important ways: it forbids imposing any new charge on ratepayers to implement these measures, and it creates a firm deadline for the use of the collected funds—any unallocated funds still on hand as of January 1, 2027, must be returned to ratepayers as bill credits. The statutory language also imports existing definitions for “access and functional needs population,” “critical community infrastructure,” “deenergization event,” and “vulnerable communities,” so the prioritization relies on preexisting definitional frameworks rather than creating new regulatory categories.
The Five Things You Need to Know
Utilities must file a status report with the PUC on awarded and unallocated Microgrid Incentive Program funds by January 15, 2026.
The PUC’s review is limited to funds collected on or before January 1, 2026, when deciding whether additional actions are needed to advance the program.
If the PUC orders further action, it must consider using a third‑party administrator to run the Microgrid Incentive Program for that utility.
Unallocated funds identified for reallocation must be prioritized to areas with two or more deenergization events, prioritizing access and functional needs populations and operators of critical community infrastructure.
Any unallocated Microgrid Incentive Program funds remaining on January 1, 2027, must be returned to ratepayers as bill credits; the PUC cannot impose additional charges on ratepayers to implement this section.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Utility reporting requirement and reporting deadline
This subsection obligates each electrical corporation to provide the PUC, by January 15, 2026, a current accounting of awarded and unallocated Microgrid Incentive Program funds tied to prior PUC decisions (Decision 21‑01‑018 and Decision 23‑04‑034). Practically, utilities will need to reconcile program award records, unspent commitments, and any administratively reserved amounts so the PUC can see the precise pool available for possible reallocation.
PUC review of unallocated funds (look‑back to Jan 1, 2026 collections)
The PUC must review the reported status and determine whether additional actions are warranted using funds collected on or before January 1, 2026. This is an evaluative mandate rather than an automatic reallocation; the PUC retains discretion to decide if reallocation or other interventions are necessary to advance microgrid deployment.
Consideration of third‑party administration
If the PUC decides further action is necessary, it must consider appointing a third‑party administrator to run the Microgrid Incentive Program for the affected utility. That option addresses potential conflicts of interest, staffing shortfalls, or program delays at utilities, but it will require the PUC to design procurement specifications and oversight terms if pursued.
Prioritization criteria and deadline for return of funds
When reallocating unallocated funds, the PUC must direct utilities to prioritize areas with two or more deenergization events, prioritize vulnerable populations (including those dependent on electric medical devices and refrigerated medication), and prioritize operators of critical community infrastructure. The subsection establishes a hard deadline: funds remaining on January 1, 2027, must be returned to ratepayers as bill credits, limiting the window for programmatic use of these particular dollars.
Limitations, definitions, and fiscal note
Subsection (b) bars the PUC from imposing new charges on ratepayers to implement this statute. Subsection (c) imports existing statutory definitions for terms used in prioritization (access and functional needs population, critical community infrastructure, deenergization event, vulnerable communities). Section 2 states the act creates a state‑mandated local program only to the extent it makes certain violations crimes and specifies no state reimbursement is required under Article XIII B, Section 6.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Residents in areas with repeated deenergization events — the bill directs unallocated funds to communities that have experienced two or more outages, increasing their chance of receiving funded microgrids or resiliency projects.
- Access and functional needs populations who rely on electric medical devices or refrigerated medication — the statute explicitly prioritizes these people when reallocations are made, improving targeted support for medically dependent residents.
- Operators of critical community infrastructure (e.g., health clinics, community shelters, refrigeration hubs) — the bill prioritizes customers whose facilities support community resiliency during outages, improving continuity for essential services.
Who Bears the Cost
- Investor‑owned electrical corporations — they must assemble and submit fund reconciliations, potentially redesign program administration, and bear transaction and procurement costs if a third‑party administrator is used.
- The PUC — the commission must conduct reviews, make determinations about third‑party administration, and oversee reallocations, increasing its workload and enforcement responsibilities.
- Potential third‑party administrators and program implementers — if engaged, they face procurement competitiveness and the operational burden of rapid program deployment within the statutory timelines, without new ratepayer funding to cover administrative costs.
Key Issues
The Core Tension
The bill balances two legitimate goals—getting dormant microgrid funds into the hands of communities at highest risk from repeated deenergization, and protecting ratepayers from new charges—but the tight deadlines and no‑new‑charge rule force a trade‑off between speedy reallocation (which may require costly, expedited administration) and careful, sustainable program deployment (which typically needs time and resources).
SB 453 narrows the PUC’s remedial toolbox in two ways that produce operational tensions. First, the bill confines review and reallocation authority to funds collected on or before January 1, 2026, and then requires returning any remaining unallocated funds by January 1, 2027.
That creates a short window for the PUC and any third‑party administrator to reprogram money, which risks rushed procurements or projects that are administratively infeasible within the timeframe. Second, by forbidding new charges on ratepayers, the bill forces any administrative or procurement costs onto utilities or third parties, or demands they be absorbed within existing program budgets—potentially reducing funds available for actual hardware and installations.
Implementation also hinges on imported definitions: “deenergization event,” “access and functional needs population,” and “critical community infrastructure” come from other statutes, so gaps or ambiguities in those cross‑references could affect prioritization. Finally, the statute’s criminal penalty hook (a violation of a PUC order can be a crime) triggers a state‑mandated local program declaration but asserts no state reimbursement—raising practical questions about prosecutorial or enforcement priorities for noncompliance that are unlikely to be resolved quickly.
