Comparison shopping is a great way to find better deals on a variety of products and services. Additionally, when consumers have more options, it can create more competition between providers and further drive down prices. Unfortunately, comparison shopping is not an option in every case.

For example, all utility companies are controlled by the Public Utilities Regulatory Authority (PURA), which sets the rates for all the residents living in a specific service area. These residents cannot switch their utility providers, and their distribution/charges will only change if they move to a different service area.

In most states, electricity rates are controlled the same way as utilities. However, this is changing in some markets as energy deregulation continues to gain popularity. Today, energy choice gives people and businesses in Connecticut and several other states the option to choose their electricity provider.

Deregulation has helped break up regional monopolies and give consumers access to better service and lower rates. However, the market can be difficult to navigate, which can create challenges for inexperienced shoppers. Having the power to choose your energy provider comes with a responsibility to research your options carefully and find the best deal.

    What To Keep In Mind While Comparing Electricity 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 have a fixed rate, so your electricity rate stays the same for the whole contract. Some plans allow you to lock in a low rate for years. Remember to check for any early cancellation fees.
    • 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.

    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. The Public Utilities Regulatory Authority (PURA) sets these charges. They are the same for all residents within your utility’s service area.
