  Fixed Rate Plans

  • Under a Fixed plan the generation rate must be Fixed for at least four complete billing cycles. Be sure to check with the supplier about the generation rate you will be charged when a Fixed plan ends.

  Variable Rate Plans

  • Under Variable-Daily or Variable-Weekly plans the generation rate can increase/decrease during your billing cycle. The generation rate for business customers can increase any amount or percentage without being notified by your supplier.

Electric Aggregators

In addition to licensing electric suppliers the Public Utilities Regulatory Authority issues a Certificate of Registration to electric aggregators.

What is an electric aggregator?

An electric aggregator gathers consumers for the purpose of negotiating the rate for generation service from an electric supplier.  An electric aggregator must negotiate with suppliers on behalf of the customers it represents. As such, an aggregator must act as the customer's agent. As a customer's agent, the aggregator may not simultaneously be an agent for one or more suppliers.

How does a registered aggregator differ from a licensed supplier?

Suppliers purchase the electricity that is provided to customers and bill for that electricity through either the customer's electric bill (commonly referred to as consolidated billing) or by directly billing the customer. Aggregators do not purchase electricity or bill for generation supply.  Instead, as noted above, aggregators gather consumers together for the purpose of negotiating the rate for generation from a supplier.

Why are aggregators allowed to post offers on Connecticut's Rate Board?

PURA oversees suppliers and aggregators and posts generally available rates to the Rate Board.  If an aggregator can offer a generally available rate to residential or business customers it may be posted to the Rate Board.

How do aggregators get paid?

Aggregators must act as the customer's agent.  As such, customers typically pay the aggregator for their service.

If I am paying an aggregator, who is my supplier?

Aggregators gather consumers and negotiate rates from suppliers on behalf of those customers.  The aggregator then selects the supplier and rate that is offered to its customers.  Customers who choose to work with an aggregator will be served through the supplier that is selected by the aggregator.

Will the name of the aggregator appear on my electric bill?

No.  Information on your bill will reflect the licensed supplier that is providing your generation service.

Standard Service

Standard Service Generation

  • Standard Service is the generation supply option provided by Eversource and United Illuminating (UI) and is available to business customers. However, customers can choose a licensed supplier for their generation services which may lower your cost.  Please note that the largest commercial and industrial customers (monthly demand greater than 500 kW) are not eligible for Standard Service but are served under Last Resort Service Generation rates.
     
  • Eversource and UI do not own electric generation plants or produce electricity.  Standard Service rates reflect the actual cost to purchase electricity. PURA oversees the auction process Eversource and UI use to purchase Standard Service Generation.
  •  
  • Standard Service Generation rates change on January 1st and July 1st and are Fixed for six months.  Eversource and UI do not offer Variable generation rates.
     
  • Customers who wish to return to the Standard Service rate must contact Eversource or UI. Eversource and UI can switch customers back to the Standard Service rate within 72 hours of the request and will prorate your bill accordingly.

FAQs

  • If you have questions or need help with choosing an electric supplier contact the Public Utilities Regulatory Authority's Consumer Affairs Unit at (800) 382-4586.

Frequently Asked Questions About Choosing A Supplier

What is Supplier Choice?
Your electric bill is divided into two major sections: delivery and generation. Since 2000 the generation portion of your bill has been deregulated, meaning that independent companies, known as “electric suppliers,” can compete to sell generation services. Customers of Eversource and UI have the option to receive generation service from a licensed supplier or to remain with and receive generation service from Eversource or UI.  The delivery costs on your bill remain fully regulated.
What are some questions that I should ask suppliers?
  • Is the generation rate fixed or variable?
  • How long is the contract?
  • Will the contract automatically renew at the end of the term?
  • Will you notify me at the end of the contract?
  • Is there an early termination fee?
  • What are the monthly savings if I switch?
  • How is the electricity generated – coal, gas, nuclear, hydroelectric, solar or wind?
  • What percentage of the electricity is produced from renewable sources?
  • Where does the renewable portion come from?
  • Is a security deposit, enrollment, or other fee required?
  • Do you offer any benefits like a home energy assessment or an enrollment bonus.
Why should I choose an electric supplier?
Most people choose an electric supplier to lower their electricity costs while others switch to support renewable energy.
How long does it take to switch my electric supplier?
The switch happens on your next meter reading date and the meter reading date is shown on your electric bill.  Be sure to ask the supplier how your meter reading date will affect the date you switch.
Is Eversource or UI my electric supplier?
Eversource and UI provide Standard Service Generation to customers who do not choose another electric supplier.
What happens after I switch to a licensed supplier?
Eversource or UI will continue to deliver electricity to your home or business and send the electric bill. The only difference is that the Generation Service rate on your bill will reflect the rate charged by the electric supplier. 
How do I return to Eversource or UI Standard Service?
You must contact Eversource or UI to return to Standard Service generation.

Do Eversource or UI own electric generating plants?
No. Eversource and UI no longer own power plants or produce electricity. Instead, they buy electricity from wholesale suppliers for delivery to customers who have not chosen an electric supplier.
Will Eversource or UI be upset if I choose an electric supplier?
No. Eversource and UI encourage their customers to choose an electric supplier to help lower energy costs.
Do Eversource or UI earn a profit by providing Standard Service generation?
No. Eversource and UI buy electricity from wholesale suppliers for delivery to their customers. All customers pay what Eversource and UI pay to purchase this electricity - no more or no less. Eversource and UI do not profit from the electricity they deliver to you; they just pass through the cost.
Can an electric supplier shut off my electricity?
No. Only Eversource or UI can shut off your electric service.
Who sends me a bill if I choose a licensed supplier?
You will continue to receive one electric bill from Eversource or UI. The only difference is that the generation rate on your bill will reflect the rate offered by the electric supplier you selected.  Some suppliers offer direct billing. If you choose direct billing you will receive two bills - one from Eversource or UI for delivery service and one from the electric supplier for generation service.
Do any suppliers offer electricity produced from wind, solar, or other renewable sources?
Yes. There are many suppliers who offer electricity produced from renewable sources and that exceed the Connecticut minimum Renewable Portfolio Standard (RPS). Look for offers that exceed the minimum RPS on Connecticut's Rate Board and be sure to ask the supplier about their renewable energy plan, how the renewable energy is generated and if the supplier buys renewable energy credits for their renewable energy offers.
What is the CTCleanEnergyOptions Program?
At present, the CTCleanEnergyOptions Program allows consumers to support the production of clean energy through a small surcharge on their electric bill. The companies that participate in the CTCleanEnergyOptions Program do not sell electricity. Instead, they support the production of clean energy through the purchase of Renewable Energy Credits, commonly referred to as RECs.
Can I choose an electric supplier and participate in the CTCleanEnergyOptions Program?
Yes.  You can participate in both or choose either of these options separately. It is important to know that the companies offering the CTCleanEnergyOptions Program are NOT electric suppliers. Instead, they use the surcharge from participating customers to support the production of clean energy throughout the United States.
