    Electricity Plan Options in Connecticut

    There are several types of electricity plans to choose from in Connecticut. Some of the most common include fixed-rate and 100% renewable plans.

    Fixed-Rate Electricity Plans

    A fixed-rate plan locks in your electricity supply rate for the length of the plan. There are no unexpected rate hikes and your rate does not change because of market conditions. You usually save more money compared to variable-rate plans, which are available in other states. A 2015 ruling by the Connecticut Public Utilities Regulatory Authority (PURA) banned variable-rate plans in Connecticut.

    100% Renewable Plans

    If you want to feel good about the energy you use, pick a 100% renewable energy electrical plan if one is available in your area. Plans marked with “100% Renewable Sources” source all energy from renewable resources such as solar and wind, reducing their impact on the environment.

    Basics of Energy Choice in Connecticut

    Before energy deregulation, the local energy utility handled all generation, transmission, and distribution in Connecticut. Because of the lack of competition, local utilities had a monopoly on the industry and were able to set energy rates as high as they liked.

    Connecticut adopted legislation in May 1998 (PA 98-28) that allowed residents to choose their electricity provider. Under the act, PURA offers licenses to third-party suppliers in order to foster a more competitive and consumer-friendly market. As this market evolved, more protections have been put in place to ensure customers are treated fairly and have more robust choices.

    Connecticut Utilities with Energy Choice

    Connecticut’s electricity needs are served by two primary utility companies, and luckily, they both offer Energy Choice to their customers.

    After switching energy suppliers, your utility provider will stay the same, so when the current plan runs out, you can compare rates again and switch to another supplier if needed.

    Reading Your Connecticut Electricity Bill

    A Connecticut electricity bill splits charges into two separate sections: delivery charges and electricity supply charges. Supply charges will change when you're switching electricity providers, but utility or delivery charges will remain the same.

    Utility Delivery Charges

    These charges mainly ensure the reliable delivery of electricity to your home. A local utility company and the Connecticut Public Utilities Regulatory Authority set these rates so they do not change based on the electricity provider.

    Electricity Supply Charges

    Electricity supply (aka, electricity generation) charges are the charges for the actual amount of electricity used. The electricity supply/generation rate is what you use when comparing electricity rates.

    If you get your electricity supply through your local utility, you can use the "Price to Compare" when comparing electricity plans. This is also listed on your bill.
