Not usually. In the United States, most public utility companies are not owned by the government — they are privately owned corporations that answer to shareholders. According to the U.S. Energy Information Administration, investor-owned utilities serve roughly 72% of the country’s electricity customers, even though they make up a small share of the total number of utilities.1U.S. Energy Information Administration. Investor-Owned Utilities Served 72% of U.S. Electricity Customers The rest of the market is split between government-owned municipal utilities and member-owned cooperatives. Which one delivers your power, water, or gas depends on where you live, and it affects how your rates are set, where any profits go, and who you complain to when something goes wrong.
The Three Ownership Models
Utilities feel like public services because they are essential and everyone uses them. That doesn’t mean the government runs them. Three ownership structures dominate the U.S. utility landscape, and they operate under very different rules.
Investor-Owned Utilities
Investor-owned utilities, or IOUs, are private companies that issue stock to shareholders like any other publicly traded corporation. They are the dominant model for electricity delivery, with about 168 IOUs serving an average of roughly 654,600 customers each.1U.S. Energy Information Administration. Investor-Owned Utilities Served 72% of U.S. Electricity Customers They earn profits for shareholders while operating under heavy state regulation. A state public utility commission approves their rates, reviews their infrastructure spending, and enforces service quality standards. The tension between shareholder returns and affordable customer rates is what drives most utility regulation in the country.
Water follows a similar pattern. The Government Accountability Office reports that privately owned water utilities serve more than 10% of the U.S. population, and state commissions regulate them much the way they regulate private electric companies.
Government-Owned Municipal Utilities
Roughly 1,958 publicly owned utilities operate across the United States, though they are typically much smaller than IOUs, averaging about 12,100 customers each.1U.S. Energy Information Administration. Investor-Owned Utilities Served 72% of U.S. Electricity Customers The category includes utilities run by cities, counties, states, federal agencies such as the Tennessee Valley Authority, and special-purpose public utility districts that residents vote into existence.
Municipal utilities answer to elected officials or locally appointed boards rather than to shareholders. Because they are government entities, they can finance infrastructure through tax-exempt municipal bonds, which lowers borrowing costs and helps keep rates down.2American Public Power Association. Municipal Bonds and Public Power They also pay no federal income tax, though many make payments in lieu of taxes to local governments to offset the revenue a taxable utility would have generated.
Member-Owned Cooperatives
About 812 electric cooperatives serve roughly 24,500 customers each, concentrated in rural areas where investor-owned utilities historically had no financial incentive to build.1U.S. Energy Information Administration. Investor-Owned Utilities Served 72% of U.S. Electricity Customers Cooperatives are nonprofit and owned by their customers. Every customer is a member with one vote in electing the board of directors, regardless of how much electricity they use. Any revenue exceeding the cooperative’s costs is returned to members or reinvested in the system.
To keep their federal tax exemption under Section 501(c)(12) of the Internal Revenue Code, cooperatives must receive at least 85% of their income from members, operate democratically, keep adequate records of each member’s ownership interest, and return surplus revenue to members proportionally.3IRS. General Survey of IRC 501(c)(12) Cooperatives and Examination of Current Issues A cooperative that fails the 85% test in a given year can lose its exemption for that year.
How to Tell Which Type Serves You
Your bill and your utility’s website usually name the owner. Look for signals like “Inc.,” “Corp.,” or a stock ticker (investor-owned), “City of…” or “Municipal Utility District” (government-owned), or “Cooperative,” “Co-op,” or “EMC” (member-owned). If the entity has an elected board of directors that only its customers vote for, it is almost certainly a cooperative. If a city council sets its rates, it is municipal. If a state public utility commission approves its rates through formal proceedings, it is most likely investor-owned.
Why the Ownership Type Matters
The ownership model shapes almost every part of a utility’s operation, and the effects reach the customer.
Where the Money Goes
An investor-owned utility exists to earn a return for its shareholders. Its approved rates include a profit margin the regulator considers reasonable. A municipal utility has no shareholders; any surplus stays with the city or gets reinvested. A cooperative returns surplus to its members. If you are served by a co-op and you see a “capital credit” refund show up occasionally, that is your share of the prior year’s margin.
Taxes and Borrowing
Investor-owned utilities pay federal and state income taxes like other corporations, and those tax costs get built into rates. Municipal utilities pay no federal income tax and can issue tax-exempt bonds. Since 1913, interest on government-purpose municipal bonds has been exempt from federal income tax, which lets municipal utilities borrow at lower interest rates than private companies.2American Public Power Association. Municipal Bonds and Public Power That borrowing advantage can translate into meaningfully lower customer rates. Qualifying cooperatives also avoid federal income tax under Section 501(c)(12), provided they meet the 85% member-income test each year and operate according to cooperative principles.3IRS.

Who You Answer To, and Who Answers to You
Customers of an investor-owned utility are not owners; they are ratepayers, and their leverage runs through the state regulator. Customers of a municipal utility are constituents of the local government that owns it, and they influence rates through the ballot box. Customers of a cooperative are members with a direct vote on the board that governs it.
Every Utility Is Regulated, Just Not by the Same Agency
Private ownership does not mean a utility is unregulated. Whether it is investor-owned, municipal, or a cooperative, a utility operates under layers of oversight designed to protect consumers and maintain reliable service.
At the federal level, the Federal Energy Regulatory Commission regulates interstate electricity transmission, wholesale electricity sales, and the transmission and sale of natural gas for resale in interstate commerce.4Federal Energy Regulatory Commission. What FERC Does Its authority under the Federal Power Act requires that wholesale rates be “just and reasonable” and prohibits undue discrimination.5Federal Energy Regulatory Commission. Federal Power Act
Safety and environmental rules apply based on what the utility does, not who owns it. A privately owned gas pipeline and a municipal gas system follow the same federal safety rules from the Pipeline and Hazardous Materials Safety Administration, which oversees roughly 2.6 million miles of pipeline under Title 49 of the Code of Federal Regulations.6PHMSA. PHMSA Regulations Every public water system, whether run by a city, a private company, or a cooperative, must meet the health-related standards the EPA sets under the Safe Drinking Water Act.7U.S. EPA. Summary of the Safe Drinking Water Act
Where regulation differs sharply by ownership is at the state level. State public utility commissions have their strongest authority over investor-owned utilities: they approve or deny rate changes, set service standards, license providers, and hear consumer complaints. Municipal utilities and cooperatives often face lighter state oversight because they already answer to local elected officials or their own members, though the specifics vary widely by state.
Service Obligations That Apply No Matter Who Owns the Wires
Every utility, regardless of ownership, carries a legal obligation to provide continuous, nondiscriminatory service to all customers within its designated service area. It generally cannot refuse to connect a new customer or cut off service without following specific procedures. The idea of universal service ensures that residents in hard-to-reach or low-income areas still receive utility service even when serving them costs more than they generate in revenue, with the added cost spread across the broader customer base.
Disconnection protections during extreme weather also apply broadly. The LIHEAP Clearinghouse reports that 42 states have cold-weather disconnection protections and 19 states have hot-weather protections. Cold-weather moratoriums commonly run from November through March, with some states triggering protections when temperatures fall below 32°F and others using fixed calendar dates. Hot-weather protections are less common but growing, with thresholds typically set at 95°F or above.8LIHEAP Clearinghouse. Disconnect Policies These protections cover most regulated utilities regardless of ownership.
Where to Take a Complaint
The right complaint channel depends on who owns the utility. For an investor-owned utility, the state public utility commission is usually the first stop. Most commissions accept informal complaints by phone or online and try to mediate. If informal resolution fails, you can file a formal complaint, which triggers a process that resembles a court proceeding: an administrative law judge holds hearings, both sides present evidence, and the commission issues a binding decision. If you disagree with the final decision, courts can review whether the commission acted within its legal authority, followed proper procedures, and based its decision on substantial evidence, though courts give regulators significant deference on technical questions.
For a municipal utility, the dispute path often runs through city hall rather than the state commission, because many states exempt government-owned utilities from commission jurisdiction. For a cooperative, you can raise issues at member meetings or through the elected board of directors, and depending on your state, formal regulatory channels may also be open. If a utility shuts off service during a weather-based protection period, your state’s public utility commission or equivalent agency is the place to file the complaint.
