How Energy Deregulation Works
Learn how deregulated energy markets separate delivery from supply, why that lets you choose your provider, and what stays the same on your bill.
If you live in a deregulated energy state, your electricity or natural gas bill is shaped by two very different companies working together. Understanding how that split works is the first step to reading your bill with confidence and making informed choices about your service.
## What Is Energy Deregulation
For most of the twentieth century, a single utility company in each region generated electricity or produced natural gas, moved it across power lines and pipelines, and sold it directly to homes and businesses. Prices were set by a state regulator, and customers had no choice of provider.
Energy deregulation changed that structure. In a deregulated market, state law separates the parts of the energy business that make sense as a monopoly — the physical wires, poles, meters, and pipelines — from the parts that can support competition, such as generating electricity or sourcing natural gas. The delivery side stays regulated. The supply side is opened up so multiple licensed companies can compete to sell energy to you.
The goal is straightforward: give consumers a choice about who supplies their energy, and let providers compete on price, contract length, renewable content, customer service, and other features.
## Regulated vs. Deregulated Markets
In a regulated market, one utility handles everything end to end, and the state public utility commission approves the rates that customer pays. There is typically no shopping option.
In a deregulated market, the same physical utility still owns and operates the wires or pipelines in your area, but the energy itself can be purchased from any licensed supplier serving your region. Some households never switch and stay on a default service rate; others actively compare plans and choose a competitive supplier. Both options are legal, and neither changes who physically delivers the energy.
Deregulation is decided state by state, and some states are partially deregulated — for example, offering choice for electricity but not natural gas, or vice versa.
## The Utility Company: Delivery
Your utility is the company that owns the poles, wires, transformers, gas mains, and meter connected to your home. In a deregulated market, the utility is responsible for:
- Maintaining the delivery infrastructure - Reading your meter - Restoring service after outages - Responding to gas leaks and safety issues - Billing for the delivery portion of your service (in many states)
Because running parallel sets of wires to every home would be wasteful and unsafe, delivery remains a regulated monopoly. Your state regulator reviews and approves the delivery charges the utility can pass on to customers. You cannot shop for a different utility — it is determined by where you live.
## The Energy Supplier: Generation and Pricing
The supplier is the company that actually sources the electricity or natural gas you use. Suppliers buy energy on wholesale markets, or generate it themselves, and sell it to end customers under a plan they design. In a deregulated market, the supplier is responsible for:
- The rate you pay per kilowatt-hour or per therm/ccf - The contract terms, such as fixed vs. variable pricing and length - Any renewable energy content advertised with the plan - Customer-facing questions about your rate and enrollment
When you shop for an energy plan, you are choosing a supplier. Everything downstream of that decision — poles, wires, meter reads, outage response — stays with your existing utility.
## How Your Bill Reflects Both
In deregulated states, your bill usually shows two main categories of charges: delivery (regulated, set by the utility) and supply (competitive, set by your chosen supplier or the default service rate). Depending on the state, these can appear on one combined bill from the utility or on separate bills. The taxes, fees, and public benefit charges you see are set by state and local rules, not by your supplier.
Because delivery is the same regardless of who supplies your energy, comparing plans is mostly about comparing the supply rate and contract terms.
## Why Choice Matters
Deregulation is what makes shopping for an energy plan possible in the first place. It is the reason you can review multiple offers, pick a contract length that fits your household, or choose a plan with a specific renewable energy mix. It also means the responsibility for reading the fine print — rate type, term length, cancellation terms, and how the plan renews — sits with the consumer.

Frequently Asked Questions
What is a deregulated energy market?
It is a market where state law separates energy delivery from energy supply. The utility still owns and operates the wires or pipelines, but multiple licensed suppliers can compete to sell you the electricity or natural gas that flows through them.
Do I have to switch providers in a deregulated state?
No. Shopping for a competitive supplier is optional. If you do not choose one, you stay on your utility's default service, sometimes called standard service or provider of last resort.
Does my utility company change if I switch suppliers?
No. Your utility is tied to where you live and does not change when you pick a new supplier. The utility continues to deliver energy, read your meter, and respond to outages and safety issues.
Will my service be less reliable if I switch to a competitive supplier?
No. Reliability depends on the physical delivery system, which the utility still operates under the same rules regardless of who supplies your energy.
How do I know if my state is deregulated?
Deregulation is set state by state and can differ between electricity and natural gas. Entering your ZIP code on 97 Options is a quick way to see what choices are available where you live.
