States with Deregulated Energy

The information below is provided by the

With the restructuring of the U.S. energy market in the 1990s, deregulation was introduced in different forms to several states. Energy deregulation allows customers to choose their own electricity and natural gas suppliers.

While many states have opened their energy markets in some form, no state is completely deregulated for all energy services and to all customers except for the District of Columbia. Today, residents of 26 states have at least some choice in their supplier for electricity, natural gas, or both.

States with Limited Choice for Residential Customers

Most states with deregulated energy markets have some sort of limitation for choosing your electric or gas suppliers. While there are typically geographical limitations based on the servicing utility’s participation in your area, some states have other restrictions.

In California, residents and small businesses in the Pacific Gas & Electric (PG&E), San Diego Gas & Electric (SDG&E), and Southern California Gas (SoCalGas) utility territories can benefit from the “Core Aggregation” program to purchase their gas from a third-party gas service provider or Core Transport Agent (CTA). 

In Florida, residential consumers at Central Florida Gas (CFG) are randomly assigned to one of two approved suppliers when they sign up for service. Still, they may call CFG to request a change to the other supplier.

In Kansas, Kansas Gas Service customers using between 800 and 1,500 Mcf (8.3 to 15.5 therms) of natural gas annually can switch to a third-party gas supplier. The average American household uses about 61.3 Mcf per year.

In Michigan, state law places a cap on the total amount of electricity that can be purchased from retail suppliers based on the local utilities’ retail sales, according to the Michigan Public Service Commission (MPSC). This practice places potential customers in a queue, essentially denying retail electric service to new Michigan residential customers. As a result of the limitation, there are currently no licensed alternative electric suppliers (AESs) providing services to residential customers in Michigan.

In Nebraska, residents can choose their gas supplier only during a two-week period in the month of April.

In New Mexico, participation in natural gas choice is currently limited but remains available by law.

In Wyoming, residents have three weeks in April to choose an alternate gas supplier.

In Virginia, residents can choose an electric supplier if they decide to buy electricity from 100 percent renewable energy sources. This option is further limited to utility customers who cannot directly purchase electricity from their utility company’s renewable sources.

In West Virginia, participation in the market is limited. Natural gas choice is technically available statewide to residents served by Peoples Gas West Virginia, Dominion Energy West Virginia, Consumers Gas Utility, or Mountaineer Gas.

States with No Energy Choice

Alternate energy supplier choice is not available to residents in Alabama, Alaska, Arizona, Arkansas, Colorado, Hawaii, Idaho, Iowa, Louisiana, Minnesota, Mississippi, Missouri, Nevada, North Carolina, North Dakota, Oklahoma, Oregon, South Carolina, South Dakota, Tennessee, Utah, Vermont, Washington, and Wisconsin. While these states may allow large industrial or commercial customers to choose their suppliers, residential customers have no access to retail energy providers.
