Standard Service

Standard Service Generation

  • Standard Service is the generation supply option provided by Eversource and United Illuminating (UI) and is available to all residential customers. However, customers can choose a licensed supplier for their generation services which may lower their cost.
     
  • Eversource and UI do not own electric generation plants or produce electricity.  Instead, they buy electricity in the marketplace to serve customers on Standard Service Generation.  So Standard Service Generation rates are based on the market price for electricity.
     
  • The Public Utilities Regulatory Authority 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.
     
  • Customers who wish to return to the Standard Service rate must contact Eversource or UI. Eversource and UI are required to switch residential customers back to the Standard Service rate within 72 hours of the request and will prorate your bill accordingly. Be sure to check with your supplier regarding cancellation fees that may apply. Learn more about returning to Standard Service Generation.

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. It is important to know that regardless of the electric supplier you choose, Eversource or UI will deliver your electricity, bill you for service, and respond to power outages. Only Eversource or UI can terminate your service.

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 licensed 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 their generation service from Eversource or UI. The delivery costs on your bill remain fully regulated.
What are some questions that I should ask suppliers?
  • 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 a cancellation fee?
  • What are the monthly savings if I switch?
  • 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 services like a home energy assessment, enrollment bonus, etc.
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 the Standard Service rate.

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.
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.
Will Eversource or UI be upset if I choose an electric supplier?
No. Eversource and UI encourage customers to keep their cost as low as possible.
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 Programare NOT electric suppliers. Instead, they use the surcharge from participating customers to support the production of clean energy throughout the United States.
