Electricity Deregulation
- 19 U.S. states plus D.C. have some form of retail electricity choice, separating generation from delivery.
- Consumers choose a retail provider for supply; the local utility still delivers power and handles outages.
- About 21.7 million households buy electricity from a competitive supplier or community choice program (EIA Form 861, 2025).

See Nevada electricity rates →What Is Electricity Deregulation?
Deregulation separates the electricity supply from the delivery infrastructure. The utility keeps the wires, but competing companies can sell electricity over them. You still get one bill — only the supply portion changes.
How Does Switching Work?
In most deregulated states, switching takes minutes and causes no service interruption:
In states with municipal aggregation (Ohio, Illinois, Massachusetts), customers may be enrolled automatically through an opt-out community program.
Does Deregulation Save Money?
Deregulation doesn’t guarantee lower prices, but it introduces competition. This historically drives down supply costs in active markets. Commercial and industrial customers tend to benefit most because they consume enough electricity to negotiate favorable contracts.
Residential Savings
Residential customers who actively compare plans can lower the supply portion of their bill, but only if the offer beats the utility's default rate. Passive customers who remain on default rates may see little difference.
The Engagement Factor
The key factor is engagement. In Texas, where shopping is essentially mandatory, the average residential price was 97.5% of the national average in 2024 (PUCT). In Ohio, government aggregation programs have driven residential switching to 67%. Suppliers must offer value to retain customers.
In states with low switching rates, fewer suppliers compete and the savings potential is more modest.
Why Some States Have Restricted Markets
Not every state that passed deregulation legislation followed through with full implementation. Several markets were scaled back or restricted after initial problems.
California — Residential Suspended Since 2001
California suspended residential direct access in 2001 after market manipulation and supply shortages triggered an energy crisis. Commercial and industrial customers can still participate, but under a cap (~28,800 GWh statewide) with a long waitlist. Separately, 25 CCA programs now serve California customers under different regulatory rules.
Michigan — 10% Cap, Fully Subscribed
Michigan passed its Customer Choice Act in 2000 but capped competitive supply at 10% of each utility’s retail sales in 2008. The program has been fully subscribed since 2009, with 5,517 participants (nearly all C&I) and 5,101 customers on the waitlist at the end of 2025.
Virginia — Expanded in 2026
Virginia allowed switching through a 100% renewable energy exception. The SCC approved Dominion’s own renewable tariff in 2020, closing that loophole. In July 2026, HB 921 removed the 1% cap; any nonresidential >5 MW customer is now eligible.
Oregon & Nevada — C&I Only
Oregon and Nevada limit choice to commercial and industrial customers, with Oregon using structured annual enrollment windows through PGE and Pacific Power.
Timeline of U.S. Electricity Deregulation
The path to competitive electricity markets began in the mid-1990s and has unfolded over three decades, with major expansions, setbacks, and ongoing policy shifts.
Natural Gas Deregulation
Many of the same states that deregulated electricity also allow consumers to choose their natural gas supplier. In deregulated gas markets, you pick the company that procures the gas. The local utility continues to deliver it through its pipeline network, the same model as electricity deregulation.
States With Natural Gas Choice
22 states plus D.C. had residential natural gas choice programs in 2024 (EIA). Among the states with electricity choice, residential gas choice is available in:
- Ohio, New York, Pennsylvania, New Jersey
- Maryland, Illinois, Massachusetts, and on a limited basis Connecticut
- Rhode Island, Michigan, California, Montana
- Virginia and Washington D.C.
Georgia is a notable exception — it has full residential natural gas choice (since 1998, in the Atlanta Gas Light territory) but remains fully regulated for electricity.
Gas vs. Electric Deregulation Gaps
Michigan also has more open gas choice than electric — while electricity is capped at 10%, natural gas choice is open to residential and business customers of four of the state's seven regulated gas utilities. Virginia follows a similar pattern, with full gas choice and only limited electric choice (expanded for >5 MW commercial customers in July 2026).
Community Choice Aggregation (CCA)
CCA programs represent a growing form of electricity choice that doesn’t fit neatly into the “deregulated vs. regulated” framework. Under CCA, a local government aggregates the buying power of residents and businesses to procure electricity supply from competitive providers, often with higher renewable energy content.
Where CCA Is Active
- California — 25 programs with about 69,600 GWh of forecast 2026 load (CPUC)
- Massachusetts — expanding municipal aggregation across the state
- Illinois — primary driver of residential switching in ComEd and Ameren territories
- Ohio — government aggregation has pushed residential switching to 67%
- New York — previously had 100+ CCA communities; one active program remained in November 2026. DPS staff formally recommended discontinuance in August 2026
How CCA Works
In Ohio and Illinois, CCA programs are the primary driver of residential switching. Customers are enrolled automatically on an opt-out basis. CCA customers keep their existing utility for delivery and billing. Only the supply source changes.
Frequently Asked Questions
What does electricity deregulation mean?
Electricity deregulation means the state allows consumers to choose their electricity supplier instead of being limited to the local utility monopoly. The utility still delivers the power over its wires, but you pick the company that generates or procures the electricity and sets the supply rate on your bill.
How many states have deregulated electricity?
19 states plus Washington D.C. have some form of retail electricity choice, 20 jurisdictions in total. The degree of access varies widely. Texas has a mandatory-choice market: in its competitive area every home buys from a retail provider. Ohio's government aggregation programs have pushed residential switching to 67%.
On the other end, Michigan caps participation at 10% of retail sales. Virginia expanded commercial access in July 2026 (HB 921 removed the 1% cap for nonresidential >5 MW customers). California suspended residential direct access entirely in 2001.
Does deregulation lower electricity prices?
Deregulation introduces competition, which can lower prices. This is especially true for commercial and industrial customers who actively shop and negotiate. Residential savings depend on engagement and on the offer: compare a supplier's price with the utility's default rate before switching.
In Texas, the average residential price was 97.5% of the national average in 2024 (PUCT). In Ohio, aggregation programs have created strong pressure on suppliers. However, passive customers who stay on default utility rates may see little difference.
Can I choose my electricity provider?
If your state is deregulated and your area is served by a participating utility, yes. Enter your ZIP code on ElectricChoice to see available plans and providers. Some states only allow commercial and industrial customers to choose (Oregon, California, Nevada).
Michigan imposes a 10% cap that's fully subscribed with a long waitlist. Virginia expanded commercial access in July 2026 (HB 921 removed the 1% cap for nonresidential >5 MW customers).
Will I lose power when I switch providers?
No. Switching electricity suppliers does not cause any interruption in service. The local utility continues to deliver power over the same wires. The only thing that changes is the supply portion of your bill — it comes from your chosen provider instead of the utility's default supply. The transition typically takes 1–2 billing cycles.
What is the difference between a utility and an electricity supplier?
A utility owns and maintains the physical infrastructure: the power lines, transformers, and meters that deliver electricity to your home. A supplier (also called a retail electricity provider, ESCO, or CRES) generates or procures the electricity that flows over those wires.
In deregulated markets, you choose your supplier while the utility continues to handle delivery and billing. See our guide to supply vs. delivery rates for more detail.
