Are you moving to Connecticut?

If you’re moving to Connecticut this summer, you should know that the state is one of about 15 where energy is deregulated. That means residents don’t have to buy electricity (or natural gas) from utilities. Instead they can buy energy from suppliers who compete on price, renewal energy mix, term length and more.

For example, the price to compare for the utility company Eversource is 10.14 cents per kilowatt hour. In the zip code 06103, a deregulated supplier offers a rate of 8.19 cents per kilowatt hour. That’s a savings of over 19 percent.

Want to find out what your savings could be? Just enter your ZIP code above and see what’s available in your area. Select a plan that fits your needs and sign up.

History of energy deregulation in Connecticut

The Connecticut Department of Public Utility Control passed PA 98-28 In May 1992  to deregulate the state’s electricity market and boost the economy. By creating a competitive market, the act allows residents to choose an electricity supplier and the rate he or she wants to pay for a home or business’s electricity.

The deregulated system also has a lower price cap, which ensures that consumers’ rates won’t skyrocket because of steadily increasing gas prices. The new deregulated system puts Connecticut electricity consumers first, so everyone can have power at the perfect rate.

Who can buy deregulated energy in Connecticut?

  • Deregulated electricity: Residencies and businesses.
  • Deregulated natural gas: Residencies and businesses.

To expand on that, both homes and businesses in Connecticut can choose a plan from deregulated electricity providers. Commercial and industrial businesses in Connecticut also have the option to purchase deregulated natural gas.

Sadly, only about 25 percent of state residents take advantage of Connecticut energy choice, according to a Energy Choice poll earlier this year.

Who provides the electricity?

With a deregulated electricity market, you choose your own electric supplier from the companies serving your region. Different suppliers charge different rates for different plans – you pick the rate that’s right for your needs.

However, your utility company is still in charge of delivering the electricity to your home or business. And don’t worry, you don’t have to tell your utility that you’ve switched suppliers, your supplier will handle all the details once your new cycle starts.If you have any problems, emergencies, power outages, etc., contact your utility company – not your supplier!

What are the different plans and products offered?

  • Fixed rate plans: Most Connecticut suppliers offer fixed rate contracts for term lengths from 6 months to 2 years. Fixed rate plans ensure predictability, in that the consumer is paying a constant rate for the entire term length of the plan’s contract.
  • Variable-rate plans: Variable-rate plans allow the consumer’s monthly rate to change from month to month. However, these plans do offer more flexibility because they do not require a long-term contract or subject the consumer to early cancellation fees.
  • Prepaid plans: The consumer pays in advance for electricity and is alerted throughout the month about usage and account balance. Some Connecticut suppliers do not require a credit check or deposit for prepaid plans.
  • Green/Renewable energy plans: Many Connecticut suppliers offer plans that use up to 100% of energy from green or renewable sources. Most of these plans include fixed rates, so the consumer’s supplier bill will be consistent from month to month.
  • Home services: Some of Connecticut’s electricity supply companies do more than just supply energy. Direct Energy, Constellation, and others offer additional products and services such as smart thermostats, HVAC installation, roof repairs and more.
  • Renewable Energy Credits (RECs): Homeowners or business owners have the option of purchasing RECs through some energy suppliers that can further offset their home or business carbon emissions and encourage local renewable energy sources.

Now that you know the lingo, you’re ready to shop for a better energy plan. Enter your ZIP code above to see what’s available.

Are there renewable energy options in Connecticut?

Yes! A stipulation of PA 98-28 requires suppliers to obtain a portion of their power from renewable sources. So, if you’re a Connecticut resident who is worried about your carbon footprint, the deregulated electric market has a plan for you. A recent poll found that 15 percent of Connecticut energy shoppersconsider renewable energy the most important factor in selecting a plan. Every electric supplier in Connecticut has at least one plan that draws some if not all its energy from renewable sources, which allows you to control your environmental impact. And with so many rate options, your love for the planet won’t put a huge dent in your bank account.

I’ve picked a plan! Now what?

If you choose to switch suppliers, you can easily cycle into your new electricity plan without any power interruptions. Your new plan will then take effect at the end of your current billing cycle (between 15 to 45 days). When your plan term is nearing its end date, Energy Choice will send you a reminder 30-60 days beforehand, giving you the opportunity to choose a new plan or continue with your supplier at a default rate.
