What is a Retail Electricity Provider?

To understand how retail electricity providers work, it’s important to distinguish between electricity providers and utility providers.

  • Utility providers, namely Eversource and United Illuminating, are responsible for maintaining power lines and infrastructure, responding to power outages, and delivering electricity to your home or business.
  • Retail Electricity Providers (aka Electricity Suppliers) – Electricity providers, on the other hand, compete to provide you with electricity supply and offer various rates and plan options.
How electricity is generated by a power plant, distributed by a utility and sold to residents through retail electricity providers in deregulated states.

The Public Utilities Regulatory Authority (PURA) plays a crucial role in overseeing Connecticut’s electricity market. PURA regulates utility companies, ensures fair competition among suppliers, and protects consumer interests. Understanding these roles helps you navigate the market more effectively and make informed decisions about your electricity supply.

What to Look For When Comparing Electricity Suppliers in Connecticut

The ElectricityRates.com Marketplace makes comparing electricity plans straightforward. However, if you’ve never switched before, there are some things you should understand.

  • Types Of Plans – Fixed-rate and variable-rate plans are the two most common plan types. A fixed-rate plan locks in your rate for the duration of your contract, while a variable-rate plan changes your rate each month. In general, it’s better to go with a fixed-rate plan as they offer more predictability and are more likely to save you money.
  • Plan Length – This refers to the length of a plan’s electricity contract. For fixed-rate plans, this shows you how long your rate is locked in for.
  • Early Termination Fees – Some plans come with cancellation fees if you cancel your plan before the end of the contract.
  • Your Electric Supply/Generation Rate – Your electricity supply rate is one of the charges that make up your total electric bill. When comparing electricity plans in Connecticut, the rates you’re comparing are electricity supply rates. You can find your current electricity supply rate on your electric bill.
  • Renewable Energy – Many suppliers offer renewable energy plans. These plans ensure that no matter how much electricity you use, an equal amount of renewable electricity goes into the grid. Renewable plans are marked in the ElectricityRates.com Marketplace.
  • Supplier Reputation – Not all suppliers are reputable. This is why ElectricityRates.com vets all suppliers before they’re featured on our site to ensure their integrity.

Choosing the right electricity provider can lead to significant savings and better service. By leveraging Energy Choice in Connecticut, you can potentially lower your electricity bills, choose plans that align with your values (like supporting renewable energy), and benefit from improved customer service and innovative offerings.
