How Many States Have Deregulated Energy?

Energy deregulation in the United States refers to the separation of generation and distribution for electricity and, in some cases, natural gas. In deregulated markets, consumers can choose among competitive providers rather than being limited to the local utility. The status of deregulation varies by state and by energy type, with electricity markets being the most commonly deregulated. This article explains where deregulation currently stands, how it affects prices and choices, and what consumers should know before selecting a supplier.

What Deregulation Means

Deregulation typically allows consumers to select their electricity or natural gas supplier, while the local utility remains responsible for distribution and grid maintenance. In many states, generation is opened to competition, but transmission and distribution remain regulated monopolies. Benefits often cited include price competition, innovative plans, and better customer service. Critics argue about potential price volatility, variable-rate plans, and complex billing. The exact structure depends on state policy, regulatory decisions, and market development over time.

Current Landscape in Electricity Markets

Electricity market structures in the United States range from fully regulated to fully competitive, with many states modernizing over the last two decades. The most significant deregulation tends to be in regions where regulatory bodies implemented customer choice for generation. In these markets, households and businesses can shop for a competitive electricity supplier, while the utility still delivers power and maintains the grid. States with retail competition typically provide a mix of plans, including fixed-rate, indexed, and renewable energy options. Overall, deregulation is most common in the Northeast and parts of the Midwest and South, though not universal even there.

Deregulation by State: A Snapshot

It is important to distinguish between electricity and natural gas deregulation and to note that the status can change with new legislation or regulatory decisions. The following snapshot reflects typical patterns in recent years:

• Texas — Maintains a largely deregulated electricity market for retail customers, with competitive generation and choice of supplier in most areas outside some municipal utilities. Texas remains the largest regulated but competitive market by scale and is often cited as a model of retail choice implementation.
• California — The state historically moved toward competition in the 1990s, but a large portion of residential and small commercial electricity remains regulated, with limited, voluntary competition in specific segments and emergency programs. Market complexity and policy priorities influence ongoing changes.
• New York — Operates with substantial customer choice in many regions, though some areas rely on regulated tariffs. The state has pursued renewable goals and targeted programs that interact with competitive suppliers and public utility commissions.
• Pennsylvania — Features a mixed landscape where some customers have choice, but many remain on default service supplied by the incumbent utility, depending on utility and local regulatory decisions.
• Illinois — Has elements of retail access in electricity with competitive suppliers available to many customers in specific jurisdictions, while other segments retain rate-regulated structures.
• Ohio — Known for its electricity market that includes competitive suppliers in parts of the state, balanced with regulated default service in others, subject to ongoing regulatory oversight.
• Nevada and New Jersey — Spots of customer choice exist in electricity markets, but default service and regulated rates are common in many areas, with ongoing policy evolution.
• Massachusetts and Connecticut — These states have mixed programs where some customers can shop, while many remain on utility-provided tariffs and procurement programs regulated by state agencies.

Note: Gas deregulation varies separately from electricity. Some states deregulated natural gas supply in limited contexts or for specific customer classes, while others maintain regulated gas tariffs with limited shopping options. The overall count of states with any form of energy deregulation grows more complex when including gas markets, municipal programs, and partial reform scenarios.

What This Means For Consumers

For consumers, the practical implications of deregulation include the ability to choose among multiple electricity or natural gas suppliers, potential price savings, and access to renewable energy plans. When evaluating options, customers should consider:

• Contract type: fixed-rate, variable-rate, or indexed plans and their risk profiles.
• Renewable content: percentage and source of renewable energy in a given plan.
• Fees and charges: enrollment fees, early termination fees, and transition charges.
• Billing and customer service: ease of switching, billing clarity, and dispute resolution processes.
• Range of options: the variety of offers available locally and any regional differences.

Regulatory agencies, such as state public utility commissions and consumer protection offices, offer resources to compare plans, read the fine print, and report concerns. It is advisable to compare offers from multiple suppliers and verify their legitimacy, especially in markets with aggressive marketing or less familiar brand names.

Recent Trends And Future Outlook

Key trends shaping energy deregulation include a growing emphasis on renewable energy procurement, time-based pricing to reflect system costs, and digital platforms enabling easier comparisons. States may revisit deregulation policies to balance consumer protections with competitive pressures, particularly in regions facing reliability concerns or high price volatility. Pending legislation and regulatory reviews could expand or restrict shopping options, influence default service terms, and redefine how utilities support grid reliability in a changing energy mix.
