Deregulated Energy Markets Explained: A State-by-State Guide for Small Business Owners in 2025

Most small business owners never question where their electricity comes from or whether they have a choice in who provides it. They receive their utility bill, pay it, and move on. But in more than a dozen U.S. states, that assumption is costing businesses significant money every single month. Deregulated energy markets allow commercial businesses to choose their electricity (and natural gas) supplier — introducing competition that can reduce supply costs by 8–20% compared to the utility's default rate. If your business operates in a deregulated state in 2025, you have a direct path to lower energy costs that millions of business owners are simply not using.

This comprehensive, state-by-state guide explains what energy deregulation is, which states have deregulated electricity and natural gas markets, and exactly how small business owners in those states can use supplier choice to lower their energy bills without any disruption to their service. We'll cover the key rules, the common pitfalls, and the strategies that are consistently delivering the best outcomes for businesses that actively manage their energy procurement in deregulated markets.

Whether you're in Illinois, Texas, Pennsylvania, New Jersey, or any of the other deregulated states, this guide gives you the information you need to take control of one of your business's largest operating expenses — and stop paying more than you have to for the same electricity everyone else receives.

What Is Energy Deregulation? How Small Businesses Can Take Control of Their Electricity Costs in 2025

Energy deregulation is a policy framework that separates the competitive aspects of electricity and natural gas supply from the natural monopoly functions of transmission and distribution, allowing multiple suppliers to compete for customers in the retail market.

The Traditional Regulated Model

In a traditional regulated electricity market, a single utility provides everything: it generates (or procures) the power, transmits it over high-voltage lines, distributes it through local networks, and bills the end customer. The state public utility commission sets rates at levels that allow the utility to recover its costs plus a regulated return. Customers have no supplier choice — they pay whatever the commission approves.

How Deregulation Changes the Model

Energy deregulation "unbundles" the supply function from the delivery function. Transmission and distribution (the poles, wires, transformers, and meters) remain under utility control, regulated by the state commission. But the supply function — the actual procurement of electricity or natural gas — is opened to competitive retail suppliers. These suppliers buy energy in wholesale markets and sell it to end-use customers at negotiated retail prices.

For small businesses, this means you can choose a retail electricity or gas supplier who will provide your commodity supply at a competitive market rate — potentially significantly below the utility's default rate. Your utility still delivers the energy to your meter; only the supplier (and therefore the supply price) changes. There is no service interruption, no equipment change, and no change to your relationship with the utility for delivery services.

Why Deregulation Saves Money

Competition drives prices down. When multiple licensed retail suppliers compete for commercial accounts, they have incentive to offer attractive fixed-rate contracts, flexible terms, and value-added services. The most competitive offers available from retail suppliers in active deregulated markets are typically more favorable than the utility's default procurement rate — which is set through regulatory auctions rather than true market competition.

According to the American Council for an Energy-Efficient Economy and market studies of deregulated state energy markets, commercial customers in active deregulated markets who work with competitive suppliers save an average of 8–18% on their energy supply costs compared to utility default rates over time.

Which States Have Deregulated Energy Markets? The Complete 2025 State-by-State Breakdown for Business Owners

As of 2025, the following states have retail electricity and/or natural gas deregulation that allows commercial customers to choose their supplier. The degree and structure of deregulation varies by state.

Fully Deregulated Electricity States (Commercial Supplier Choice Available)

Key Differences Between State Markets

While all of these states offer commercial supplier choice, they differ in important ways:

• Texas (ERCOT) is the most aggressively competitive market — full supplier choice with no regulated default rate "backstop" for most accounts. The widest range of pricing options but also the highest exposure to market volatility without a fixed contract.
• Illinois (PJM/ComEd) has a robust competitive market with 20+ licensed retail suppliers. The utility ComEd maintains a "default supply" rate that acts as a backstop but is typically more expensive than competitive offers during favorable market windows.
• ISO-New England states (MA, CT, NH, ME, RI) have well-developed competitive markets but smaller supplier ecosystems than PJM states. The capacity market premium is significant in New England, making competitive procurement especially valuable.
• New York (NYISO) has a complex market structure with significant differences between zones. Downstate (NYC/Long Island) markets have the highest rates and the most active supplier competition.

How to Choose the Best Energy Supplier for Your Small Business in a Deregulated State (And Avoid Costly Mistakes)

Supplier choice is only valuable if you make an informed choice. Here's how to navigate the process correctly.

Step 1: Verify Your Eligibility

Confirm that your business address is in a deregulated service territory. In states with limited deregulation (like Michigan and Virginia), there may be capacity limits or minimum usage thresholds. Your utility's website or a commercial energy broker can confirm your eligibility quickly.

Step 2: Gather Your Usage Data

Obtain 12 months of utility bills showing monthly kWh usage and peak demand (kW). In many states, your utility provides this data through an online portal or through Green Button data downloads that can be shared directly with suppliers for quoting purposes.

Step 3: Use a Licensed Commercial Energy Broker

A commercial energy broker licensed in your state contacts multiple retail suppliers simultaneously, obtains competitive quotes for your account, and presents them in a standardized comparison format. This is the most efficient way to access the full breadth of the market without spending weeks contacting individual suppliers. See our guide to choosing the right commercial energy broker for a detailed framework.

Costly Mistakes to Avoid

• Accepting the first offer: The first supplier you contact will quote their own rate — which may not be the market's best. Always compare at least three offers before signing.
• Ignoring early termination fees: Some commercial energy contracts carry significant ETFs if you exit early. Understand the fee structure before signing.
• Auto-renewing without shopping: Many commercial energy contracts include auto-renewal clauses that lock you into a new term at prevailing market rates (which may be higher) if you don't actively renegotiate. Set calendar reminders 90 days before your contract end date.
• Comparing rates without understanding what's included: Always compare all-in supply rates, not just "energy" rates that exclude capacity, transmission, or renewable energy compliance costs.
• Choosing an unlicensed supplier: Verify that any supplier you consider is licensed by your state's utility regulatory authority. Working with unlicensed suppliers creates legal and billing risk.

Top Money-Saving Strategies Small Business Owners Are Using Right Now in Deregulated Energy Markets

Beyond simply switching suppliers, the most financially effective small business operators in deregulated markets use several additional strategies.

Strategy 1: Multi-Year Fixed Contracts During Low-Rate Windows

Locking in a 24 or 36-month fixed contract during seasonal or cyclical low-rate windows captures favorable pricing for multiple years, amplifying the savings compared to annual or month-to-month procurement. Spring months (March–May) typically offer the most favorable procurement windows in most deregulated markets.

Strategy 2: Commercial Natural Gas Supplier Choice

In most deregulated states, natural gas supply is also a competitive market. Small businesses with significant gas consumption (restaurants, manufacturers, healthcare facilities) can lock in competitive fixed-price gas supply contracts that protect against winter natural gas price spikes. This is an often-overlooked savings opportunity separate from electricity procurement.

Strategy 3: Green Energy Products and REC Procurement

Several deregulated markets offer commercial customers the ability to purchase 100% renewable energy supply products at competitive rates. For businesses with sustainability goals or ESG reporting requirements, this can satisfy environmental commitments while still delivering cost savings compared to utility default rates. Our guide on renewable energy certificates explains the mechanics in detail.

Strategy 4: Annual Contract Benchmark Review

Even if you're on a fixed contract that's mid-term, annually benchmarking your current rate against current market offers keeps you informed about your relative cost position. If your fixed rate is significantly above current market, you may choose to evaluate early termination economics. If it's below market — as it should be if you signed during a favorable window — that benchmark confirms the value of your proactive procurement decision.

Frequently Asked Questions

What is a deregulated energy market?

A deregulated energy market allows commercial and sometimes residential customers to choose their electricity or natural gas supplier, rather than being required to buy from the local regulated utility. The utility still delivers the energy; only the supply procurement is opened to competition.

Does switching suppliers affect my power reliability?

No. Physical delivery of electricity is handled by your utility regardless of which supplier you choose. Reliability, grid maintenance, and outage response remain the utility's responsibility and are entirely unaffected by supplier choice.

How much can a small business save by switching suppliers in a deregulated state?

Savings depend on your current rate, consumption level, and prevailing market conditions. In active deregulated markets like Illinois and Texas, commercial customers who proactively shop the market during favorable windows typically save 8–18% on supply charges. For a business spending $3,000/month on electricity, that's $2,880–$6,480 per year in potential savings.

Is my state deregulated?

The major deregulated states for commercial electricity include Illinois, Texas, Pennsylvania, New Jersey, New York, Massachusetts, Connecticut, Ohio, Maryland, Delaware, New Hampshire, Maine, and Rhode Island. See the full table earlier in this article for details.

What happens if my retail electricity supplier goes out of business?

If a licensed retail supplier goes bankrupt or fails, state regulations require that affected customers are transitioned to the utility's default supply rate without service interruption. Your electricity will continue flowing without any action on your part. However, you should promptly shop for a new competitive supplier to avoid remaining on the (typically more expensive) default rate.

Can multi-location businesses use a single energy contract across multiple deregulated states?

Some larger retail suppliers and energy brokers can coordinate energy procurement across multiple deregulated states for multi-location businesses, simplifying contract management and potentially leveraging aggregate volume for more competitive pricing. See our guide on energy management for multi-location businesses for details.
