- question: Which states have deregulated electricity? answer: "As of 2025, the following states have full or partial retail electricity choice for residential customers: Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan (partial), New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Texas, Virginia (partial), and the District of Columbia. Some additional states offer choice only for commercial/industrial customers."
- question: Is deregulated electricity cheaper? answer: Not always. Competitive markets create opportunities for lower rates, but they also expose consumers to marketing gimmicks, variable rate traps, and complex contracts. Research from the Retail Energy Supply Association and consumer groups shows mixed results — informed shoppers can often save 5–15%, while those on default or variable rates may pay more.
- question: What happens if my energy supplier goes out of business? answer: Your electricity does not shut off. The local distribution utility is obligated to continue delivering power. You'll be placed on the utility's default "Provider of Last Resort" (POLR) rate, which may be higher than competitive rates, until you choose a new supplier.
- question: Can I switch to renewable energy through deregulation? answer: Yes. Many competitive suppliers offer 100% renewable energy plans, typically backed by Renewable Energy Certificates (RECs). The physical electrons are the same, but the RECs ensure an equivalent amount of renewable generation is added to the grid on your behalf.
Electricity Deregulation Explained
In most of the 20th century, electricity was a regulated monopoly: one company generated, transmitted, and distributed power in each service territory, with rates set by a state commission. Starting in the 1990s, about a third of U.S. states restructured their electricity markets to allow consumer choice in who generates their electricity.
How Regulated Markets Work
In a regulated (or "vertically integrated") state:
- One utility handles everything: generation, transmission, and distribution
- Rates are set by the state Public Utility Commission (PUC) through formal rate cases
- Customers have one option for electricity service
- The utility earns a guaranteed rate of return on its investments (typically 9–11%)
This model provides stability but limits competition and innovation.
How Deregulated Markets Work
In a deregulated (or "restructured") state:
- Generation is separated from distribution (unbundled)
- Multiple Retail Electric Providers (REPs) compete to sell you electricity
- The local utility still owns and maintains the wires and meters (distribution)
- Your bill may come from the REP, the utility, or both
You choose your supply rate but have no choice in the delivery charge — that remains with your local distribution utility and is regulated.
The Two Parts of Your Bill
| Component | Who Controls It | Can You Choose? | |-----------|:-:|:-:| | Supply (generation) | Competitive suppliers | Yes | | Delivery (distribution) | Local utility | No | | Transmission | Regional grid operator | No |
States with Retail Choice
Full residential choice: Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Texas, DC
Partial or limited choice: Michigan (10% cap on switching), Virginia (available but few suppliers active), Montana (suspended for residential), Oregon (limited)
Notable: Texas has the most active competitive market, with 100+ retail electric providers and a dedicated shopping site (PowerToChoose.org) operated by the PUC.
How to Shop for Electricity
Key Terms
- Fixed rate: Price per kWh locked for a contract term (6, 12, 24 months). Provides budget certainty.
- Variable rate: Price changes monthly based on wholesale market conditions. Can be cheaper in mild months but spike during extreme weather.
- Indexed rate: Tied to a wholesale market benchmark plus a markup.
- Renewable plan: 100% of your usage matched with Renewable Energy Certificates (RECs).
What to Watch For
- Teaser rates that jump after 1–3 months
- Early termination fees ($50–$200 for breaking a fixed contract)
- Usage tiers — some plans offer low rates only above a minimum usage threshold
- TDU (delivery) charges — make sure you're comparing total all-in costs
- Autopay/paperless requirements for advertised prices
Shopping Strategy
- Check your current all-in rate on your latest bill (total charges ÷ total kWh)
- Visit your state's official comparison site (e.g., PowerToChoose.org in Texas, PA Power Switch in Pennsylvania)
- Filter for fixed-rate plans with terms matching your preference
- Add delivery charges to the supply rate for a true apples-to-apples comparison
- Read the Electricity Facts Label (EFL) or equivalent disclosure document before signing
Impact on Renewable Energy
Deregulated markets have accelerated renewable energy adoption in several ways:
- Green choice plans: Customers can actively choose 100% wind or solar-backed plans
- Corporate PPAs: Large buyers (Google, Amazon, Walmart) contract directly with renewable generators in competitive markets
- Competitive pressure: Suppliers compete on both price and green credentials
However, deregulation has also created challenges: some states (notably Texas) have experienced extreme price volatility during weather events, and the competitive market can be confusing for less-engaged consumers.
