What Is Electricity Deregulation?

The electricity market in the United States operates under two major models: regulated and deregulated.

In regulated states, a single utility company controls both the generation and distribution of electricity.

In deregulated states, consumers have the power to choose their electricity provider, naturally leading to more competition and potentially lower rates. If you live in a deregulated area, knowing your options can help you save on energy costs and find a cost-effective plan that’s tailored to your usage profile.

How Deregulation Works: REPs vs. Your Utility

Deregulation splits your electricity into two separate functions, which is why your bill has two distinct charges.

Your utility company owns the physical infrastructure — the power lines, transformers, and meters that physically deliver electricity to your home. You cannot choose your utility. It’s determined by where you live, and it stays the same regardless of who you pay for electricity.

Your retail electricity provider (REP) is the company you actually choose. REPs purchase electricity on wholesale energy markets, package it into consumer plans, and sell it to you. When you “switch electricity providers,” you’re only switching your REP — not your delivery infrastructure.

This matters because your utility still responds to outages, still reads your meter, and still maintains the lines outside your home. Switching providers doesn’t change any of that.

Two documents to know when shopping for a REP:

Electricity Facts Label (EFL): Required in Texas, this one-page document shows your true rate at 500, 1,000, and 2,000 kWh usage levels, the energy sources powering your plan, and all fees. Always compare EFLs — not the advertised headline rate, which can be misleading.

Your Rights as a Consumer (YRAC): A disclosure document explaining your rights against unauthorized switching (slamming), unauthorized charges (cramming), and your right to fair service. Worth reading once so you know what protections exist.

Pros and Cons of Deregulated Electricity

Deregulation isn’t universally better or worse than regulated markets. The outcomes depend heavily on how informed you are as a consumer.

What works in your favor:

Competition between dozens of REPs creates real pricing pressure, especially during off-peak seasons. Consumers who actively shop — particularly in Texas, Ohio, and Pennsylvania — can find rates 10–20% below the default utility tariff. Deregulated markets also offer plan variety that regulated markets simply don’t: 100% renewable plans, free nights and weekends, prepaid plans with no credit check, and fixed-rate contracts that lock in your price for up to 3 years.

Where consumers get caught out:

Variable-rate plans are the biggest trap in deregulated markets. These plans have no fixed rate — your price can change month to month based on wholesale market conditions. During extreme weather events like Winter Storm Uri in Texas (February 2021), some customers on variable plans saw bills spike to 10–20x their normal amount in a single month. If you’re on a variable plan, understand the risk before summer or winter arrives.

Promotional rates are another common issue. Some REPs advertise an attractive introductory rate that expires after 3–6 months, automatically rolling you into a higher variable rate. Reading the EFL carefully and noting your contract end date prevents this.

Common Consumer Mistakes in Deregulated Markets

Comparing advertised rates instead of EFL rates. The headline rate you see advertised is often only accurate at exactly 1,000 kWh usage. At 500 kWh or 2,000 kWh, the effective rate is often significantly different due to base charges and tiered pricing. Always check the EFL at your actual usage level.

Missing the contract end date. When a fixed-rate contract expires, most REPs automatically roll you onto a month-to-month variable rate — often 30–50% higher than your contracted rate. Setting a calendar reminder 45–60 days before your contract ends gives you time to shop without pressure. See our guide to finding your contract end date.

Assuming green energy plans are more expensive. In deregulated markets, 100% renewable plans — powered by wind or solar RECs — are often competitively priced with standard plans, sometimes even cheaper. If you’re in Texas, Pennsylvania, Ohio, or Illinois, it’s worth comparing green plans directly.

Ignoring base charges. Some plans have low per-kWh rates but include a $9–$15 monthly base charge regardless of usage. Low-usage households (under 700 kWh/month) often pay less on plans with slightly higher per-kWh rates but no base charge.

Green Energy in Deregulated Markets

One of the least-discussed advantages of deregulated electricity is the ability to specifically choose how your power is generated — not just what you pay for it.

In regulated states, your utility decides the energy mix. In deregulated states, you can select a plan where 100% of your supply is matched by renewable energy certificates (RECs) from wind farms, solar installations, or hydroelectric sources.

RECs work by ensuring that for every kilowatt-hour you consume, an equivalent kilowatt-hour of renewable energy is fed into the grid somewhere. Your physical electrons still come through the same wires, but your consumption is matched and offset by verified clean generation.

Texas is the largest wind energy producer in the US, which means 100% wind plans are widely available and often affordable in the ERCOT market. Pennsylvania and Illinois both have active green energy markets with competitive pricing. If reducing your carbon footprint is a priority, a deregulated market is one of the few places a residential consumer can directly act on that preference.

Which States Have Deregulated Electricity?

Not all states in the U.S. have deregulated electricity markets. Some of the major states with electricity deregulation include:

• Connecticut
• Delaware
• Maine
• Massachusetts
• New Hampshire
• Texas

In these states, consumers can choose from multiple electricity retailers, each offering different rates, contract lengths, and renewable energy options.

Which States Have Deregulated Electricity and Gas?

In some states, residential consumers have the option to choose their electricity and gas provider in states like:

• Illinois
• Maryland
• Massachusetts
• Michigan
• New Jersey
• New York
• Ohio
• Pennsylvania
• Rhode Island
• Washington, DC

Electricity Prices Are Complicated

Although competition aims to lower costs, electricity deregulation has shown varied outcomes depending on how it’s implemented.

For example:

• Some national data shows that residential customers in deregulated states paid significantly more per kilowatt-hour on average than those in regulated states – in one analysis, about 42% more.
• However, this trend is not uniform and can largely depend on regional factors like fuel costs, infrastructure investment, and regulation.
• Further, data from Texas in earlier years showed residential electricity prices dipping below the national average after deregulation, though this gap fluctuated over time.

This illustrates that pricing outcomes are not solely driven by deregulation itself.

Rather, they also reflect the market, fuel prices, grid investments, and policy choices.

Additionally, not all deregulated markets look the same.

Other regions and states have experienced major issues when deregulation was poorly designed, most famously the California electricity crisis in 2000–2001, which saw supply instability and huge price spikes.

How have Electricity Prices Have Changed Over Time?

According to data from the U.S. Energy Information Administration (EIA), the average residential electricity price in the United States has roughly doubled since 2000, rising from about 8 cents per kilowatt-hour to over 16 cents per kilowatt-hour in 2024.

As mentioned above, this trend doesn’t mean deregulation alone caused prices to rise. Instead, it highlights a key feature of competitive electricity markets: prices respond to broader economic forces rather than remaining fixed by regulation.

In deregulated states, retail electricity providers purchase power from wholesale markets and pass those costs, along with risk, to consumers through different types of plans. When fuel prices rise or grid demand increases, retail rates often follow. When markets soften, consumers who actively shop can sometimes secure lower rates than those available under a fixed regulated tariff.

To get a clearer picture of how volatile electricity prices are, let’s take a look at how prices have changed over the last 20 years.

Because deregulated electricity markets rely on competition rather than fixed, regulator-approved rates, prices tend to evolve with broader economic and energy market conditions. Examining how residential electricity prices have changed over the past 20 years provides useful context for understanding why electricity bills today look very different from those of the early 2000s, even when household usage hasn’t changed much.

If you live in a deregulated state, taking the time to compare plans can lead to significant savings and better service. Whether you’re looking for a lower rate, a green energy plan, or flexible contract terms, there’s likely a provider that fits your needs.
