Electricity in California is partially deregulated: the state opened power generation to competition in the 1990s but kept the wires, poles, and meters that deliver power to your home under the control of a regulated monopoly utility. That means you may be able to choose who produces your electricity, but you cannot choose who delivers it, and the delivery company still sends your bill. For most residential customers, the practical choice comes down to staying with the default utility supply or being enrolled in a local Community Choice Aggregator.
What California Deregulated and What It Didn’t
Two parts of the electricity system work very differently in California.
Power generation is competitive. Independent generators, renewable developers, and out-of-state producers all sell electricity into the state’s wholesale market. The Federal Energy Regulatory Commission oversees that market, and the California Independent System Operator (CAISO) manages the physical flow of power across the high-voltage grid for about 80 percent of the state’s demand.1Federal Energy Regulatory Commission.

Transmission and distribution are not competitive. The poles, wires, substations, and transformers between the grid and your house are treated as natural monopolies. One utility owns that infrastructure in each service territory, and the California Public Utilities Commission (CPUC) sets what it can charge to use it.2California Public Utilities Commission. Regulatory Services No matter who generates your power, it travels over those same wires.
So when people ask whether California has deregulated electricity, the honest answer is “half of it.” The generation half is open; the delivery half is not.
Why Full Deregulation Didn’t Last
California tried broader deregulation once. Assembly Bill 1890, signed on September 23, 1996, broke apart the old vertically integrated utility model and set up a competitive wholesale market along with new institutions to run it.3U.S. Energy Information Administration. California Electric Energy Crisis – Provisions of AB 1890 The law also froze retail rates at June 1996 levels and required an immediate 10 percent discount for residential and small commercial customers running through 2002.4California State Legislature. AB 1890 Assembly Bill – Chaptered
Between 2000 and 2001, supply shortages, trader manipulation, and surging demand sent wholesale prices soaring. Utilities had to buy expensive power at market rates while the rate freeze blocked them from passing those costs through. Rolling blackouts followed. The state stepped in to buy power directly, one major utility filed for bankruptcy, and the fully competitive retail market was dismantled. What remained is the hybrid system California still uses today.
Can You Actually Choose Your Provider?
Whether you have any choice at all depends on who delivers your electricity. California has two very different kinds of utilities.
Investor-Owned Utilities
Pacific Gas and Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E) are privately owned, publicly traded companies regulated by the CPUC.5California Energy Commission. Electric Load-Serving Entities in California Together they cover most of the state’s electricity customers. Each has an exclusive distribution territory, and each also serves as the default power supplier if you don’t choose an alternative. If you’re served by one of the three, you have access to the choice programs described below.
Municipal and Publicly Owned Utilities
About a quarter of California customers are served by publicly owned utilities such as the Los Angeles Department of Water and Power and the Sacramento Municipal Utility District. These are government entities answerable to local boards rather than the CPUC.6California Public Utilities Commission. Helpful Resources for Areas Not Regulated by the CPUC If your bill comes from a municipal utility, the state-level choice programs don’t apply to you. Your rates and any local supplier options are set by your utility’s governing board.
Community Choice Aggregation
Community Choice Aggregators (CCAs) are local government programs that buy electricity on behalf of residents and businesses in their jurisdiction. More than two dozen now operate across California, serving over 15 million customers across hundreds of cities and counties. Most emphasize higher renewable content than the default utility supply, and many offer generation rates comparable to or slightly below the utility’s.
When a CCA launches in your area, you are enrolled automatically. California law guarantees your right to opt out and return to utility generation at any time.7California Legislative Information. California Public Utilities Code 366.2 If you opt out within the first 60 days or two billing cycles, there’s no penalty. After that, opting out locks you into utility service for at least 12 months before you can rejoin.8California Public Utilities Commission. Community Choice Aggregation – Consumer Information Each CCA posts opt-out instructions on its website; methods vary from a phone call to a postcard to an online form.
A CCA is not a competitive marketplace. If one exists where you live, you have one option plus the utility default. If none exists, you have only the utility default.
Direct Access
Direct Access lets customers contract with a licensed Energy Service Provider for their electricity supply. This was the broad retail competition that AB 1890 originally introduced. It was suspended during the energy crisis and has only been partially reopened.
The statewide cap sits at roughly 28,800 gigawatt-hours after SB 237 added 4,000 GWh in 2018, and the CPUC recommended against further expansion in 2021 because it could not confirm the expansion would meet state emissions goals or avoid shifting costs to remaining utility customers.9California Public Utilities Commission. Direct Access In practice, Direct Access is available almost exclusively to large commercial and industrial users, and even they have faced a waitlist for years. Residential customers cannot sign up.
The Fee That Follows You When You Leave
Whether you switch to a CCA or a Direct Access provider, the investor-owned utility still delivers the power and handles billing. You will also likely see a Power Charge Indifference Adjustment (PCIA) on your bill. The PCIA exists because the utility signed long-term power contracts on behalf of all customers before some of them left for other suppliers. The fee makes departing customers pay their share of those legacy contract costs.
When the utility’s contracted power costs more than its current market value, the PCIA is a charge. In rare cases where contracts come in below market value, it can be a credit.10California Public Utilities Commission. Power Charge Indifference Adjustment The PCIA has been a point of friction between CCAs and the utilities because it can erase whatever rate savings a CCA might otherwise offer over the utility’s generation charge.
Why Competition Hasn’t Made California Electricity Cheap
As of January 2026, California residents pay an average of 30.29 cents per kilowatt-hour, nearly double the national average of 17.45 cents.11U.S. Energy Information Administration. Electric Power Monthly Only about 12 to 15 cents of a typical bill represents the generation component that is open to competition. The rest covers regulated delivery, infrastructure, and state-mandated programs.
Most of California’s rate premium over other states comes from the delivery side rather than the generation side. Wildfire mitigation spending, grid hardening, and undergrounding programs have pushed distribution costs up significantly in recent years, and those costs are set through the CPUC’s rate-setting process rather than through any competitive market. Switching to a CCA can change the generation line on your bill. It cannot change the delivery line, and the delivery line is where most of the pressure sits.
So if you came to this question hoping to shop for a cheaper electricity provider the way you might shop for internet service, the honest answer is that California doesn’t work that way. Generation is competitive at the wholesale level, residential retail choice is limited to whether a CCA happens to serve your address, and the regulated delivery charges apply either way.
