Regulated vs. Deregulated Electricity Markets: What's the Difference?

Why some households can choose their electricity provider and others cannot. How regulated and deregulated markets work and how they affect your electric bill.

Electricity prices can vary widely from state to state — and one of the biggest reasons is whether a state operates under a regulated electricity market or a deregulated electricity market. Understanding the difference helps explain why some households can choose their electricity provider while others cannot, and why rates fluctuate more in certain areas.

This guide breaks down how regulated and deregulated electricity markets work, the pros and cons of each, and how they affect your monthly electric bill.

In the U.S., most states use regulated electricity markets, but some (like Texas and parts of the Northeast and Midwest) allow customers to choose competitive retail electricity suppliers.

What Is a Regulated Electricity Market?

In a regulated electricity market, a single utility company controls the generation, transmission, and distribution of electricity within a defined service area. Customers do not have a choice of electric provider.

Key characteristics of regulated markets:

  • One utility serves each region
  • Rates are approved by a state public utility commission
  • Pricing changes happen slowly and predictably
  • Utilities earn a regulated rate of return

In these states, electricity prices are typically set through formal rate cases that consider fuel costs, infrastructure investments, and operational expenses.

Most U.S. states still operate under regulated electricity markets. Some examples we cover:

What Is a Deregulated Electricity Market?

In a deregulated electricity market (or competitive electricity market), electricity generation and retail sales are opened to competition. Customers can choose from multiple electricity suppliers, while the local utility continues to handle power delivery and infrastructure.

Key characteristics of deregulated markets:

  • Multiple electricity suppliers compete for customers
  • Consumers can shop for rates and plans
  • Prices are more likely to fluctuate based on market conditions
  • Utilities still maintain power lines and reliability

In these markets, your electric bill is usually split into:

  • Supply charge (from your chosen provider)
  • Delivery charge (from the local utility)

Which States Have Deregulated Electricity Markets?

Deregulation is more common in parts of the Northeast, Midwest, and Texas. Examples we cover include:

Even within deregulated states, not all utilities participate fully, and rules can vary by service territory.

How Market Structure Affects Your Electric Bill

Regulated markets:

  • Typically, more stable pricing
  • Fewer sudden rate swings
  • Limited ability to shop for cheaper electricity
  • Long-term infrastructure costs are spread evenly

Deregulated markets:

  • Potential for lower short-term rates
  • Greater price volatility
  • Risk of teaser rates and contract expirations
  • Requires active monitoring by consumers

A deregulated market can offer savings — but only for consumers who actively compare plans and understand contract terms.

Common Gotchas in Deregulated States

Watch for these when shopping in competitive markets:

  • Intro or teaser rates that increase after the first term
  • Early termination fees if you switch providers before the contract ends
  • Variable-rate plans that change month to month
  • "Green" plans that are REC-based (renewable energy certificates) — not always local generation

Why Two Cities in the Same State Can Have Different Electric Costs

Even within the same market structure, electric bills can vary because of:

  • Different utility service territories
  • Local infrastructure costs
  • Fuel mix (coal, natural gas, nuclear, renewables)
  • Transmission and distribution fees
  • State and local taxes

This is why comparing city-level utility costs provides a clearer picture than looking at state averages alone.

Is Deregulation Better for Consumers?

There is no universal answer.

Deregulation can benefit consumers who:

  • Regularly compare providers
  • Understand contract terms
  • Monitor rate changes
  • More plan options (fixed-rate, green energy, prepaid)

Regulated markets often benefit consumers who:

  • Prefer predictable billing
  • Do not want to shop for electricity
  • Value long-term price stability
  • Less plan shopping (one default utility rate set through regulation)

Both systems aim to balance affordability, reliability, and infrastructure investment — they just approach it differently.

How to Use This Information When Comparing Utility Costs

When comparing electricity costs between cities or states:

  1. Check whether the area is regulated or deregulated
  2. Look at electric rates at a standardized usage level (our examples use 1,000 kWh)
  3. Consider local delivery fees and non-electric utilities (water, sewer, trash)

Understanding the market structure adds important context to any utility cost comparison.

Final Thoughts

Electricity market structure plays a major role in how prices are set and how much control consumers have over their bills. Whether regulated or deregulated, each system comes with tradeoffs that influence cost stability, competition, and consumer choice.

When comparing utility costs by city or state, market structure helps explain why prices differ — not just how much they differ.

See average utility costs by state, then compare cities side-by-side (electricity + water + sewer + trash where available).
