What To Keep In Mind While Comparing Suppliers In Connecticut
The ElectricityRates.com Marketplace makes comparing electricity plans straightforward, but there are still a few things you should understand before you make the switch.
- Electricity Supply/Generation Rate – Your electricity supply rate is how much you pay for each kilowatt-hour (kWh) of electricity you use. It’s one of the many different charges that go into your electric bill. This is the number you want to use while comparing electricity plans.
- Plan Length – Most plans on ElectricityRates.com are fixed-rate plans, which means your electricity rate will be locked in for the duration of your contract. Some plans allow you to lock in a low rate for years. Just be sure to take note of any cancellation/early termination fees that you will have to pay if you cancel before your contract ends.
- Renewable Energy – Many suppliers offer renewable energy plans. These plans ensure that no matter how much electricity you use, an equal amount of renewable electricity goes into the grid. Renewable plans are clearly marked in the ElectricityRates.com Marketplace.
- Supplier Reputation – ElectricityRates.com’s Provider Score system can help you find the best suppliers in your area. On top of that, ElectricityRates.com vets all electricity suppliers before they’re featured on our site to ensure their integrity.

Electric Companies In CT: Utility vs Supplier
If you’re new to Energy Choice in Connecticut, you should know the difference between your electricity supplier and your utility provider.
- Utility Provider – This is the company that delivers electricity to you and bills you. The two main utility providers in Connecticut are Eversource and United Illuminating (UI). On your electric bill, charges for distribution/delivery go to your utility provider. You cannot switch utility providers.
- Electricity Supplier (aka Electricity Provider) – Your electricity supplier is the company that supplies the electricity you use. By default, your electricity supplier in Connecticut is your utility provider, but you have the option to switch. On your electric bill, the charges that support your electricity supplier are under supply/generation charges.
Since you can’t switch utility providers, the distribution/delivery charges will not change when you switch suppliers. These charges are set by the Public Utilities Regulatory Authority (PURA) and are the same for all residents within your utility’s service area.
