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 electric provider. The act required the two electric utilities and the Department of Public Utility Control (DPUC) to establish a competitive market. The law also required the companies to unbundle (separate) their generation components from the rest of their businesses by October 1, 1999.

100% Renewable Plans

Reading Your Connecticut Electricity Bill

Your Connecticut electricity bill splits charges into two separate sections, delivery charges and electricity supply charges. Your supply charges will change when you switch electricity providers and utility or delivery charges will remain the same.

Utility Delivery Charges

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

Electricity Supply Charges

Electricity supply (aka. electricity generation) charges are the charges for the electricity you use. Your 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.
