The Public Utility Commission of Texas (PUCT) is the state agency that licenses every retail electric provider, sets consumer protection rules, and handles complaints when those rules are broken. It does not operate the grid, generate electricity, or approve retail electricity prices. Those functions belong to different entities. Understanding what the PUCT actually controls helps Texas households know when the agency can help them and when a different approach is more practical.
PUCT vs. ERCOT: Two Different Jobs
The PUCT and ERCOT appear together in most coverage of the Texas electricity market, which can blur the distinction between them. They perform fundamentally different functions.
The PUCT is a state government agency created by the Texas Legislature. Its five commissioners are appointed by the governor and confirmed by the Senate. The PUCT writes and enforces the rules that govern the retail electricity market. It licenses every retail electric provider (REP) operating in Texas, sets the terms under which providers can market to customers, and resolves disputes between consumers and providers.
ERCOT (Electric Reliability Council of Texas) is a nonprofit membership organization that operates the electric grid for roughly 90 percent of the state (ERCOT, 2025). ERCOT manages the flow of electricity across approximately 46,500 miles of high-voltage transmission lines, balances supply and demand in real time, and coordinates the wholesale electricity market where power plants sell electricity to providers.
A useful analogy: ERCOT is the highway system. The PUCT is the Department of Motor Vehicles and the traffic court combined.
How the PUCT Licenses Retail Electric Providers
Before any company can sell electricity to Texas households, it must hold a PUCT certificate of operating authority. The licensing process requires applicants to demonstrate financial capability, post a security deposit or bond, and agree to comply with the PUCT's customer protection rules (PUCT Substantive Rule 25.107).
As of 2025, the PUCT oversees more than 100 licensed REPs operating in the competitive service territory (PUCT, 2025). That number includes large national retailers, Texas-based startups, and green-energy specialists. The license is not permanent. The PUCT can suspend or revoke a provider's certificate for billing violations, failure to maintain adequate financial reserves, or repeated consumer protection failures.
Consumer Protections the PUCT Enforces
The PUCT's consumer protection rules set a floor below which no provider can go. Key protections include:
Disclosure requirements. Every provider must give customers an Electricity Facts Label (EFL) before enrollment. The EFL discloses the rate structure, any fees, the contract length, and the average price per kilowatt-hour at 500, 1,000, and 2,000 kWh of monthly usage. The format is standardized by the PUCT so shoppers can compare plans side by side.
Switch timing. Providers cannot delay a customer's switch to a competing provider. Once a customer enrolls with a new provider, the switch must complete within two to three billing cycles (PUCT Substantive Rule 25.272).
Deposit limits. Providers can request a deposit from customers with no credit history or poor credit, but the PUCT caps that deposit at the greater of $50 or one-fifth of the customer's estimated annual bill. The deposit earns interest and must be returned within 30 days of account closure if the customer has paid on time for 12 consecutive months (PUCT Substantive Rule 25.478).
Disconnection rules. Providers cannot disconnect service on Fridays, Saturdays, Sundays, or state holidays. During extreme weather events, the PUCT may issue moratoriums on disconnections. In the summer months (June through September), disconnection is prohibited when the temperature is forecast to exceed 100 degrees Fahrenheit (PUCT Substantive Rule 25.483).
How to File a PUCT Complaint Against an Electricity Provider
When a provider bills incorrectly, refuses to process a switch, or violates any of the rules above, the PUCT offers a formal complaint process. The steps are straightforward.
Step 1: Contact the provider first. PUCT rules require that customers attempt to resolve the dispute directly with the provider before filing a formal complaint. Call the provider's customer service line and document the call: date, time, representative's name, and the outcome. Keep copies of all bills and any written communications.
Step 2: File a complaint with the PUCT. Complaints can be filed online through the PUCT's Interchange system, by phone at 1-888-782-8477, or by mail. The complaint form asks for the customer's account number, provider name, a description of the problem, and supporting documents.
Step 3: The PUCT contacts the provider. Once a complaint is accepted, the PUCT notifies the provider and sets a deadline for a response. Most complaints are resolved through this informal mediation process. Providers typically have 21 days to respond (PUCT, 2025).
Step 4: Formal proceeding, if needed. If the provider's response does not satisfy PUCT staff, the case can escalate to a formal proceeding before an administrative law judge. Formal proceedings are less common but are available as a backstop.
A realistic expectation: the PUCT's informal complaint process resolves most billing and service disputes without a formal hearing. However, the PUCT cannot award monetary damages beyond a refund of overcharges. Customers seeking compensation for losses caused by a provider's conduct may need to pursue a separate civil claim.
What the PUCT Does Not Control
Understanding the PUCT's limits is as useful as understanding its authority.
The PUCT does not set retail electricity prices. Texas deregulated its retail market under Senate Bill 7 in 1999, which means providers compete freely on price. The rate a customer pays reflects market conditions, not a rate approved by any regulator.
The PUCT does not operate or maintain the physical grid. That is ERCOT's domain, subject to Federal Energy Regulatory Commission (FERC) oversight of wholesale markets and interstate transmission.
The PUCT does not cover the entire state. Customers served by municipal utilities such as Austin Energy or CPS Energy in San Antonio, or by electric cooperatives in non-deregulated territory, are generally governed by their local utility's board rather than the PUCT for most rate and service decisions.
When to Switch Providers vs. When to File a Complaint
The deregulated market gives Texas households the ability to switch providers at any time without involving the PUCT. If a current rate is simply higher than alternatives available in the market, the practical step is to compare plans and switch. The U.S. Energy Information Administration reported an average Texas residential retail rate of 12.0 cents per kWh in 2024 (EIA, Electric Power Monthly, 2025), but plans available on the open market frequently range from 9 cents to 16 cents per kWh depending on contract length and usage tier. Switching is faster and less adversarial than a formal complaint.
A PUCT complaint is appropriate when a provider has violated the rules: billed for service not delivered, blocked a switch, refused to return a deposit that is legally owed, or disconnected service in violation of the timing rules described above. These are conduct violations, not price dissatisfaction, and the PUCT is the appropriate venue for them.
The PUCT's Role After Winter Storm Uri
The February 2021 storm exposed coordination failures between the PUCT and ERCOT that the Texas Legislature addressed directly in Senate Bill 3 (2021). The legislation gave the PUCT expanded oversight authority over ERCOT, required ERCOT board members to be Texas residents, and directed the PUCT to develop weatherization standards for power generators. The PUCT's commissioners at the time of the storm resigned, and the Legislature subsequently restructured the commission's governance.
The post-Uri regulatory changes are relevant to consumers because they represent an ongoing process of institutional reform. The PUCT continues to issue new rules on weatherization compliance, demand response programs, and market design. Customers who want to follow these developments can monitor the PUCT's open docket list, which is publicly accessible and searchable by topic.
For most households, the PUCT's practical value is twofold: it ensures that every provider selling electricity in Texas has met a minimum standard, and it provides a clear escalation path when a provider crosses a line. Knowing both the agency's reach and its limits helps consumers focus their energy in the right direction.
