  • How to Change Your Electric Supplier in CT
Print

It is easy to change your electric supplier in CT, because you reside in a state that gives residents and businesses the right to choose the energy supplier they prefer.

Connecticut residents enjoy a deregulated energy market. Instead of buying power from a single electricity utility company, you have energy choice. Many providers vie for your business with competitive prices, innovative plans and energy solutions and excellent customer service.

The process for how to change your electric supplier in CT is straightforward, but you will want to consider various aspects to make the right choice for you.

Why Change CT Electric Suppliers?

You may wish to change electricity suppliers in CT for a variety of reasons. When you choose the right supplier and plan, you can enjoy a number of benefits. Competitive energy suppliers offer advantages over utilities. These advantages make it attractive to change your electricity supplier in CT:

  • Lower costs: As companies compete to get you to change your electric supplier in CT, they may offer lower rates and discount incentives.
  • Attractive contract options: You can opt for fixed-rate plans that protect you from changing electric supply rates, renewable energy plans for power generated from wind, solar and/or hydro and flexible time-of-use plans, to name a few.
  • Dedicated customer service: Through helpful customer support staff, companies work hard to keep you happy.
  • Reputation: It all adds up to earning a positive reputation. When you change your electric supplier in CT, you want to choose a reputable company.

How to Change Your Electric Supplier in CT

How to change your electric supplier in Connecticut.

When it comes to how to change an electric supplier in CT, the process is easy—especially when you choose a provider that helps at every step.

  1. Research companies offering electricity in CT. Check their reputation and review their plans and benefits. You’ll also want to compare electric rates in Connecticut to ensure you’re getting the right plan for your household energy usage and budget.
  2. Understand your current plan and usage. Review your current provider’s contract. Review recent bills and read your electric meter so you have a good idea of your usage. Also, CT suppliers do not charge an early termination or cancellation fee.
  3. Sign up for service. You can easily complete this step online and most companies can also support you by phone, if you prefer. You don’t have to do anything else, as service with Constellation will switch over without interruption or hidden fees.

Things to Consider When Switching Suppliers in Connecticut

Knowing what aspects to think about when asking “how do I change my electric supplier in CT” will help you make a solid choice. You’ll put yourself in the best situation when you make an informed decision about suppliers and plans.

  • Determine your options. Find out what companies are licensed in CT and understand the charges, fees and taxes that the state requires. The best supplier will make this information readily available and easy to understand.
  • Understand your current costs. Look at recent bills to see how much power you use and what you pay. You will have a good benchmark to compare against competitive offers.
  • Ensure the electric supplier is reputable. Reputation matters because it is earned over years of service and over millions of customers. Constellation, for example, has a 25-year track record in 16 states, supporting 2 million customers.
  • Consider customer service. Ask friends, check social media and read online business reviews. Give the company a call. If problems arise or your needs change, you want to depend on fast, reliable and truly helpful responses.

How Long Does It Take To Switch Energy Providers in CT?

The process to change an electric supplier in CT takes a few minutes of your time. However, the change may take up to three billing cycles to become effective per the CT regulations governing supplier switching.

What Do I Need to Switch Electricity Providers in CT?

  • To change your electric supplier in CT, you will need:
  • The address where you want to establish service.
  • The name of the person responsible for the bill.
  • An idea of your usage levels, patterns and existing rates so you can choose the right plan.

Will I Lose Electricity While I Switch?

Your service will not be interrupted when changing electric suppliers in CT. Your utility or current supplier will continue to provide service throughout the transition, making the process seamless.

How Often Can I Switch Suppliers?

Connecticut allows you to change electric suppliers at any time without a cancellation fee, meaning you can switch suppliers whenever you choose.

Who Do I Call if There’s a Power Outage—My Utility or My New Provider?

Your local utility maintains the infrastructure for delivering electricity to your business or home. If the power goes out, contact the utility company directly and report the outage.
