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.

Connecticut residents still receive their electric supply from their local utility by default. However, now they have many more providers and electricity rate options to choose from.  A study done by the Retail Energy Supply Associaton found that Connecticut residents and businesses have millions in savings potential by switching to a retail electricity provider.

How to Compare Connecticut Electricity Rates lets you compare Connecticut providers and plans side by side in our Electricity Marketplace. All you have to do is follow this simple three-step process:

Switch Connecticut Electricity Providers for the Best Rates
  1. Enter your zip code – This shows you the providers and plans available in your area.
  2. Compare electricity providers and plans – Compare available plans and choose the rate, plan length and plan type that is right for you.
  3. Switch electricity providers – Select your new rate, fill out the necessary information and make the switch.

After that, your new provider will take care of the rest. There are no interruptions in your service and your local utility provider remains the same. The only thing that changes is your electricity rate.

Types of Electricity Plans in Connecticut

There are several types of electricity plans to choose from in Connecticut. Here are some of the most common.

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.

100% Renewable Plans

If you want to feel good about the energy you use, pick a 100% renewable energy electricity plan. Plans marked with “100% Renewable Sources” source all energy from renewable resources. Renewable plans are also usually fixed-rate plans.

Electricity Plans With Incentives

Some electricity plans come with incentives bundled in. A good example of this is Constellation’s Power to Connect Electricity Plan, which comes bundled with the Constellation Connect Energy Package. When a plan has incentives, lists them in the “plan details” section. Electricity plans with incentives are also usually fixed-rate plans.

Variable-Rate Electricity Plans

A variable-rate plan has a rate that changes from month to month based on market conditions. The primary benefit of a variable rate plan is flexibility. There are usually no cancellation fees, so if you are not living in one place for a very long period of time, it may be beneficial to choose one.

However, they almost always cost you more in the long run. There are also no caps on how high they can take electricity rates, so the costs on your electricity bill might surprise you.

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.
