How choice works in Connecticut
Households can buy energy from a licensed supplier while the local utility keeps delivering it and sending the bill.
Eversource and United Illuminating buy power for customers who do not choose a supplier and charge it as standard service. The price is updated on a regular schedule.
- What a supplier changes: the price and terms of the energy you buy, and often the company that sends the bill.
- What it does not change: your delivery utility, your meter, outage service and the poles and wires.

How to compare offers in Connecticut
Compare offers with your utility’s current standard service rate and read the rate type carefully.
The official comparison site is EnergizeCT. Start there, because it is run for consumers.
Ready to switch? Read the Connecticut switching guide for the steps, the rules we checked and what to confirm first.
- Find your current default price and the date it will next change.
- Ask each supplier for the price, the type, the term, every fee and the early termination fee in writing.
- Compare over a full year, not one month.
- Check what happens when the term ends.
The state’s Energize Connecticut program lists licensed electric suppliers and their current offers. Ask any supplier to explain the rate type and when the price can change before you agree.
Your utility continues to deliver the power and send the bill. A supplier changes the supply rate only.
Five questions to ask before you sign
- What is the price per kWh, and is it fixed or variable?
- How long is the term, and what is the fee for leaving early?
- Are there monthly charges, minimum usage fees or conditions on credits?
- What happens when the term ends, and how will I be told?
- How long do I have to cancel after signing?
Your rights and where to complain
Suppliers are licensed or registered with the state, and the Connecticut Public Utilities Regulatory Authority handles complaints. Keep a copy of your contract and any call or email confirmation. If you think you were switched without permission, tell your utility and your regulator right away.
