AB 2463 directs the California Public Utilities Commission (CPUC) to open a quasi‑legislative rulemaking by April 1, 2027 to establish a baseline capital‑market risk framework that becomes the analytical reference for setting authorized returns on equity (ROE) for electrical and gas corporations. The bill requires that the baseline identify typical business, financial, and regulatory risks—accounting for rate recovery tools and revenue stabilization—and makes that baseline rebuttable only if a utility proves it faces materially greater risk.
Beyond the baseline, the bill forces the CPUC to adopt a clear strategy tying downward ROE adjustments to specified load‑growth or sales‑volume triggers, to reexamine the cost‑of‑capital adjustment mechanism for symmetry and credibility, to ensure ROE for transmission‑level customer‑funded projects reflects actual utility capital at risk, and to evaluate incentive‑based return models (including pilots) linking shareholder earnings to performance outcomes. The package is designed to sharpen the link between market conditions, utility risk, and shareholder compensation—shifting analytical burden, evidentiary standards, and possible financial consequences for utilities and investors while aiming to protect ratepayers.
At a Glance
What It Does
The bill requires a CPUC rulemaking to create a baseline capital‑market risk framework that serves as the default analytical reference for ROE decisions, subject to rebuttal only on a showing of materially greater risk. It mandates a strategy with prospective, transparent triggers to reduce ROE when load growth or sales volume sufficiently decreases per‑unit revenue risk, and directs reviews of the cost‑of‑capital adjustment mechanism, transmission‑level customer‑funded projects, and incentive‑based ROE pilots.
Who It Affects
All electrical and gas corporations regulated by the CPUC, their investors and credit providers, large transmission‑level customers and project developers who fund infrastructure, CPUC analysts and intervenors, and California ratepayers who ultimately pay authorized returns.
Why It Matters
This changes the baseline for ROE determinations from a case‑by‑case assessment to a prescriptive framework that can lower authorized returns when market or operational conditions reduce utility risk, potentially reducing ratepayer costs, altering utility financing economics, and encouraging performance‑linked compensation structures.

What This Bill Actually Does
AB 2463 makes the CPUC do more than occasional ROE tweaks: it forces the commission to build a standardized analytical baseline that identifies the ordinary business, financial, and regulatory risks utilities face and to treat that baseline as the starting point for every authorized equity return. The baseline must account for classic risk‑mitigating features of regulated cost‑of‑service utilities—things like authorized cost recovery, revenue stabilization mechanisms, and regulatory oversight—so that the ROE reflects net market risk, not a gross, unadjusted figure.
Once the baseline exists, utilities carry the burden when they claim they face higher-than‑baseline risk. The bill raises the evidentiary bar: a utility must prove it has 'materially greater' risk to justify an upward departure, and any such departure requires express, evidence‑based findings.
Conversely, the commission can set ROE at or below the baseline without the utility having to make any showing—effectively making downward adjustments administratively easier if supported by record evidence.The bill also makes risk adjustments operational. The CPUC must craft clear, prospective triggers tied to measurable load‑growth or sales thresholds that, when met, lead to downward adjustments in ROE.
That turns what is often a qualitative judgment about changing risk into a rule‑based mechanism—and pushes the commission to balance predictability for investors against savings for ratepayers.Finally, AB 2463 tackles two practical edge cases. First, it requires the CPUC to rework the existing cost‑of‑capital adjustment mechanism to ensure it moves symmetrically—both up and down—based on market conditions, and to fix instances where the mechanism was suspended or failed to reduce ROE when appropriate.
Second, it directs the CPUC to reassess how it compensates utilities for infrastructure where initial capital comes from transmission‑level customers or other third parties; the ROE in those cases must reflect the utility’s actual capital at risk unless the CPUC expressly finds comparable risk was assumed. The bill also instructs the commission to evaluate and potentially pilot incentive‑based return models that tie some shareholder earnings to outcomes such as interconnection speed, cost control, reliability, safety, and risk reduction.
The Five Things You Need to Know
The CPUC must open a quasi‑legislative rulemaking by April 1, 2027 to set a baseline capital‑market risk framework that will serve as the standard reference for ROE decisions.
The baseline is rebuttable only if a utility proves it faces 'materially greater' risk; upward departures require express findings based on substantial evidence, while the commission may set ROE at or below the baseline without a utility showing.
The CPUC must adopt a strategy with clear, prospective load‑growth or sales‑volume triggers that produce downward ROE adjustments when thresholds are met, to reflect reduced per‑unit revenue risk.
The bill mandates a comprehensive review of the cost‑of‑capital adjustment mechanism to check for asymmetry, examine past suspensions/non‑triggers, evaluate ratepayer and shareholder impacts, and adopt fixes to improve objectivity.
For transmission‑level projects funded in whole or part by customers or third parties, the commission must ensure authorized ROE reflects the utility’s actual capital at risk and may pilot incentive‑based return models linking shareholder earnings to performance.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Rulemaking to review ROE and cost‑of‑capital methodologies
This section directs the CPUC to open a systemwide, quasi‑legislative proceeding by a set date to reassess how it calculates cost of capital and authorized ROE for every electrical and gas corporation. By mandating a single, systemwide rulemaking, the bill centralizes what are often piecemeal, utility‑specific analyses and signals that the commission should consider structural reforms rather than isolated adjustments.
Baseline capital‑market risk framework and evidentiary rules
The commission must create a baseline framework identifying typical business, financial, and regulatory risks, explicitly factoring in regulatory risk‑mitigants (e.g., cost recovery and revenue stabilization). The framework carries a presumption: utilities must demonstrate 'materially greater' risk to rebut it, and any upward deviation requires express, substantial‑evidence findings. Practically, this changes litigation and testimony strategies—intervenors and utilities will focus on evidence showing material divergence from the baseline rather than re‑arguing every component of market risk from scratch.
Load‑growth and sales triggers for downward ROE adjustments
The CPUC must design a transparent strategy that links specific load‑growth or sales thresholds to prospective downward adjustments in ROE, recognizing that sustained growth can lower per‑unit revenue volatility. The mandate for 'clear, prospective triggers' implies the commission should define measurable metrics and timing so that utilities and investors can anticipate adjustments rather than face retroactive or ad hoc changes—an important shift for financial planning and rate forecasting.
Comprehensive review of the cost‑of‑capital adjustment mechanism
This section forces a forensic look at the existing adjustment mechanism to determine whether it responds symmetrically to market movements and whether past suspensions or non‑triggers were justified. The CPUC must measure shareholder vs. ratepayer impact and adopt fixes to improve objectivity and credibility—likely by tightening trigger rules, clarifying suspension criteria, or embedding automaticity where appropriate.
ROE for transmission‑level customer‑funded projects
For projects where a transmission‑level customer or third party provides initial capital (advances, prepayments, etc.), the CPUC must ensure the authorized ROE reflects the utility’s actual capital at risk. The commission cannot simply assign the same equity return used for utility‑financed assets unless it finds the utility assumed comparable financial exposure. This provision nudges treatment of customer‑funded infrastructure toward lower equity compensation unless clear utility risk remains.
Evaluation and pilots for incentive‑based return models
The CPUC must study alternative models that tie part of shareholder compensation to measurable performance outcomes and can implement pilots or phased approaches. By authorizing pilots and integration into ratemaking, the bill opens a path for performance‑linked returns on metrics like timely interconnections, cost control, reliability, safety, and risk reduction—shifting some compensation from guaranteed returns to outcome‑based rewards.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- California ratepayers: If the CPUC lowers authorized ROE when load growth or market conditions reduce revenue risk, customers may pay lower carrying costs on rate base and see downward pressure on rates over time.
- Large transmission‑level customers and project sponsors: When third parties fund initial capital, the bill requires ROE to reflect the utility’s actual capital at risk, which can reduce the premium paid by those customers compared with a full utility ROE.
- Project developers and interconnection applicants: The requirement that the CPUC consider mechanisms to remove disincentives for timely interconnection could speed project delivery and lower delays that currently add project cost.
- Regulatory consistency advocates and intervenors: A single baseline framework and clearer triggers reduce case‑by‑case variability, making outcomes more predictable and analyses more comparable across utilities.
Who Bears the Cost
- Electrical and gas corporations: Utilities face a higher evidentiary burden to justify ROE above the baseline and risk lower authorized returns when load growth triggers are met, which could reduce shareholder earnings.
- Investors and creditors: Reduced ROE or increased use of performance‑based returns can compress expected equity returns and change risk profiles, potentially raising the cost of capital or affecting credit spreads.
- Utility compliance, finance, and regulatory teams: Designing rebuttal evidence, monitoring load/sales triggers, and engaging in new pilots will require additional modeling, reporting, and administrative work—raising near‑term compliance costs.
- Third‑party funders and equity partners: If ROE on customer‑funded projects falls to reflect lower utility risk, third parties may receive less favorable overall compensation or need to adjust financing structures.
Key Issues
The Core Tension
The bill pits two valid objectives against each other: protecting ratepayers from overpaying for equity when market or operational changes reduce per‑unit risk, versus preserving utilities’ ability to attract capital and maintain service by providing predictable, adequate returns. Lowering ROE in response to reduced risk benefits customers but can raise the cost of capital or deter investment; keeping ROE high protects investment attraction but risks imposing unnecessary costs on ratepayers—there is no mechanical fix that fully satisfies both aims.
The bill delegates a heavy analytical task to the CPUC with few prescriptional calibrations, which creates two implementation risks. First, translating a qualitative concept like 'baseline risk' into a defensible, auditable framework requires extensive empirical work—defining inputs, sensitivity analysis, and boundary conditions—while the statute leaves key design choices (metrics, lookback windows, load definitions) to the commission.
That opens the door to litigation over methodology and to stakeholder pressure to skew parameters in ways that advantage particular parties.
Second, the rule‑based triggers for downward ROE adjustments create forecasting and gaming risks. Load growth and sales volumes are noisy and influenced by policy drivers (electrification incentives, economic cycles, behind‑the‑meter adoption).
If triggers are set too aggressively, utilities may face premature ROE reductions that raise their financing costs; if set too conservatively, ratepayers get little benefit. The requirement to align ROE for customer‑funded projects with 'capital at risk' raises allocation questions: how to split construction, operational, and performance risk between the utility and funder, and how to treat contingent obligations or guarantees.
Finally, incentive‑based returns shift compensation risk to shareholders but create measurement and verification burdens; poorly designed metrics can encourage short‑termism or gaming and complicate enforcement.
Practical rollout will also depend on CPUC capacity. The agency must conduct systemwide empirical reviews, design robust triggers, run pilots, and adjudicate disputes under higher evidentiary standards—all tasks that require technical staff and time.
Absent additional resources or very careful scoping, the CPUC risks protracted proceedings and interim uncertainty that could itself influence utility financing behavior.
