The California Public Utilities Code is the state law that governs how investor-owned electric, gas, water, telecommunications, and transportation companies operate in California. It sets the rates they can charge, the safety rules they must follow, and the protections customers are entitled to, and it gives the California Public Utilities Commission (CPUC) broad authority to enforce every part of it. If you pay a PG&E bill, ride with a licensed rideshare driver, live near a rail crossing, or get water from an investor-owned utility, the code shapes your service.
What the Code Actually Governs
The code reaches nearly every essential service delivered by a private utility. On the energy side, it covers how electricity and natural gas are priced, how renewable targets are met, and how utilities must prevent their equipment from starting wildfires. On the water side, it applies to more than 100 investor-owned water and sewer utilities that together serve about 16 percent of Californians.1California Public Utilities Commission. Water Division Publicly owned water systems are not regulated by the CPUC; they answer to federal and state drinking water agencies instead.
The code also governs telecommunications service quality, broadband deployment programs, railroad safety inspections, and transportation network companies like Uber and Lyft. Recent additions include Division 4.1 on wildfire safety, which reaches both privately and publicly owned utilities, and the Digital Infrastructure and Video Competition Act of 2006, which handles video and broadband franchising.
Who Enforces the Code
The CPUC is the primary enforcer. Five commissioners, appointed by the Governor and confirmed by the State Senate, serve staggered six-year terms.2California Public Utilities Commission. Divisions Section 701 grants the commission sweeping authority to “supervise and regulate every public utility in the State” and to take actions “necessary and convenient” to carry out that jurisdiction.3California Legislative Information. California Code PUC – Section 701 That covers rate approvals, infrastructure decisions, licensing, investigations, and penalties.
Public participation is built in. Utilities seeking rate increases must give at least five days’ notice before a hearing and publish that notice in local papers. Anyone can formally intervene by filing a written petition, and members of the public can appear at hearings and state their position without becoming a formal party.4California Public Utilities Commission. Rules of Practice and Procedure Ex parte rules limit private lobbying of decision-makers outside those public channels.5California Public Utilities Commission. Rules of Practice and Procedure – Section: Rule 4 Applicability
How Rates Get Set
Section 451 is the foundational rate rule. Every charge a utility imposes must be “just and reasonable,” and every utility must maintain adequate service and facilities for the safety, health, comfort, and convenience of its customers.6California Legislative Information. California Code PUC – Section 451
That standard gets applied through the General Rate Case, a formal proceeding that runs about 18 months from filing to final decision. Phase 1 sets the utility’s total revenue requirement. Phase 2 divides that amount among residential, commercial, and industrial customer groups.7California Public Utilities Commission. Understanding How the CPUC Processes a General Rate Case The CPUC holds public forums across the service territory, takes written comments through its docket, and runs formal evidentiary hearings where consumer advocates and local governments can cross-examine the utility’s witnesses.
Consumer Protections You Can Use
Bill Discounts for Lower-Income Households
The California Alternate Rates for Energy (CARE) program, authorized by Section 739.1, gives qualifying customers a 30 to 35 percent discount on electricity and a 20 percent discount on natural gas from the state’s large investor-owned utilities. Smaller utilities with fewer than 100,000 accounts offer a 20 percent electricity discount.8California Public Utilities Commission. CARE/FERA Program
Eligibility runs off household income or enrollment in programs like Medi-Cal, SNAP, or WIC. For June 2025 through May 2026, a one- or two-person household qualifies at up to $42,300 in income, and a four-person household at up to $64,300.8California Public Utilities Commission. CARE/FERA Program
Before a Utility Can Shut Off Your Service
Residential gas and electric disconnections for nonpayment require a three-step notice process. A 15-day written notice comes first. About ten business days later, a 48-hour notice follows, with in-person visits required for customers on life support or medical baseline. On the day of disconnection, the utility must make an outbound phone call offering a payment plan. All notices must be provided in the top five languages spoken in the service territory.
Disconnection is prohibited when a medical professional certifies that termination would be life-threatening to someone in the household and the customer is willing to enter a payment arrangement. Service also cannot be cut while a formal complaint against the utility is under review. Most utilities voluntarily halt disconnections during the late-December holiday season.
Clean Energy Rules That Show Up on Your Bill
Renewable and Carbon-Free Targets
The Renewables Portfolio Standard, codified starting at Section 399.11, requires 50 percent renewable electricity by the end of 2026 and 60 percent by 2030.9California Legislative Information. California Code PUC – Section 399.11 SB 100, signed in 2018, layered a broader target on top: all retail electricity from carbon-free resources by 2045. The 2045 target is wider than the RPS because it counts zero-carbon sources like large hydro and nuclear that do not qualify as “renewable” under the RPS definitions.10California Public Utilities Commission. Renewables Portfolio Standard Program
Rooftop Solar Under Net Billing
Since April 2023, new rooftop solar customers connect under the net billing tariff, which replaced the older net energy metering framework. Excess electricity exported to the grid earns bill credits based on the value of that generation to the grid, not the full retail rate. Credit values change over time and can occasionally exceed the retail rate during late-summer evenings.11California Public Utilities Commission. Net Energy Metering and Net Billing
Residential customers of PG&E and Southern California Edison who interconnect before the end of 2027 get a temporary nine-year adder that boosts their export credits. Customers already on NEM 2.0 can stay on it for 20 years from their interconnection date, or voluntarily switch to the current tariff at any time.11California Public Utilities Commission. Net Energy Metering and Net Billing
Community Choice Aggregation
Section 366.2 lets cities and counties form Community Choice Aggregation (CCA) programs that buy electricity on behalf of local residents while the incumbent utility continues to deliver it. Customers are automatically enrolled when a CCA launches in their area and can opt out at any time.12California Legislative Information. California Code PUC – Section 366.2 The CPUC authorizes CCAs only after imposing a cost-recovery mechanism so remaining utility customers don’t absorb stranded costs.
Wildfire Safety Rules
Wildfire risk drives some of the most active parts of the code. Section 8386 requires every electrical corporation to build, maintain, and operate its lines so as to minimize the risk of catastrophic wildfire. Each utility submits an annual wildfire mitigation plan covering at least three years, addressing vegetation management, infrastructure inspections, public safety power shutoff protocols, effectiveness metrics, and undergrounding strategies in high-risk areas.13California Legislative Information. California Public Utilities Code 8386.3
Plans must also spell out how the utility will protect vulnerable customers during shutoffs, including medical baseline customers on electrically powered life-support equipment. Utilities may deploy backup power or provide financial assistance if the customer demonstrates financial need. The Office of Energy Infrastructure Safety, an independent state office, must approve or deny each plan within nine months of submission and conducts field inspections to verify compliance.14Office of Energy Infrastructure Safety. Office of Energy Infrastructure Safety
AB 1054, signed in 2019, created the Wildfire Fund to help participating utilities pay catastrophic fire claims without collapsing or shifting the full cost to ratepayers. The fund was initially capitalized with a $10.5 billion loan from the state’s Surplus Money Investment Fund, plus billions in utility contributions; large electrical corporations contribute $300 million a year, adjusted by an allocation metric. Utilities that draw on the fund must reimburse it over time, though the reimbursement obligation is capped based on a percentage of the corporation’s equity rate base, and the state carries no liability for claims exceeding the fund’s balance.15California Legislative Information. AB 1054
Rideshare and Rail
Uber, Lyft, and Other Rideshare Coverage
Rideshare platforms operate as transportation network companies (TNCs) licensed by the CPUC. Insurance requirements track where the driver is in a trip:
- Period 1 (app on, waiting for a match): $50,000 per person for death or injury, $100,000 per incident, and $30,000 for property damage.
- Period 2 (match accepted, en route to pickup): $1,000,000 for death, injury, and property damage, plus $1,000,000 in uninsured and underinsured motorist coverage.
- Period 3 (passenger in the vehicle): the same $1,000,000 combined coverage as Period 2.
Vehicles must pass inspection by a facility licensed by the Bureau of Automotive Repair annually or every 50,000 miles, whichever comes first.16California Public Utilities Commission. Overview of Transportation Network Company Regulations The CPUC also enforces a zero-tolerance drug and alcohol policy for drivers.17California Public Utilities Commission. Transportation Network Companies
Rail Inspections and Grade Crossings
The CPUC’s Rail Safety Division inspects rights-of-way, equipment, and operations. Under Section 309.7, the division must employ enough federally certified inspectors to check locomotives and equipment in Class I railroad yards at least every 180 days and to inspect all main and branch line tracks at least every 12 months.18California Public Utilities Commission. Federal Laws, State Laws, and CPUC General Orders on Railroads The commission can also require utilities to install and maintain safety devices at grade crossings, from interlocking signals to block signaling systems.
Where the Code Stops and Federal Law Takes Over
The CPUC regulates retail electricity transactions, meaning what you actually pay. Wholesale electricity sales between suppliers and utilities are handled by the Federal Energy Regulatory Commission.19Federal Energy Regulatory Commission. An Introductory Guide to Electricity Markets Regulated by the Federal Energy Regulatory Commission Grid reliability is governed federally too: under Section 215 of the Federal Power Act, the North American Electric Reliability Corporation writes mandatory reliability standards, FERC approves them, and utilities must comply.20North American Electric Reliability Corporation. US Reliability Standards
For water, federal law sets the floor. Under the Safe Drinking Water Act, California retains primary enforcement authority only if its rules are at least as stringent as EPA standards, if it updates its rules within two years of any EPA revision, and if it maintains inspection and emergency planning capacity.21U.S. Environmental Protection Agency. Primacy Enforcement Responsibility for Public Water Systems The CPUC’s regulation of investor-owned water utilities sits on top of that federal baseline.
Penalties and How to File a Complaint
Section 2107 sets a default penalty of $500 to $100,000 per offense when a utility violates the state constitution, a section of the code, or any CPUC order, decision, rule, or directive.22California Legislative Information. California Public Utilities Code 2107 Section 2108 treats every violation as a separate offense, and each day a violation continues counts separately, so sustained noncompliance can add up quickly.
Beyond fines, the CPUC can order corrective action, mandate operational changes, and open formal investigations with subpoena power that reaches facilities, records, and testimony. For wildfire safety, revenues approved for a utility’s mitigation plan cannot be diverted to unrelated programs.
If you have a dispute with your utility, you can file an informal complaint with the CPUC’s Consumer Affairs Branch at no cost, and the utility cannot disconnect your service while that complaint is being resolved. Formal proceedings follow the commission’s Rules of Practice and Procedure, with the same public hearing and intervention rights that apply in rate cases.
