What is the Price to Compare in Connecticut?
The Price to Compare (PTC) is the per-kilowatt-hour (kWh) your local utility charges for electric supply, acting as a benchmark for comparing third-party supplier offers. It represents the generation and transmission portion of your bill, which can be replaced by a competitive supplier to save money.
Connecticut Price to Compare (PTC) by Utility
| Utility Name | Price to Compare (¢/kWh) | Effective Date | Electricityrates.com Price |
|---|---|---|---|
| Eversource Energy | 12.64¢ | January 1, 2026 | 11.69¢ |
| United Illuminating (UI) | 13.70¢ | January 1, 2026 | 11.69¢ |
Utility vs. Energy Suppliers
A utility company owns and maintains the physical infrastructure (poles, wires, substations) and is responsible for the delivery, maintenance, repair, and billing of electricity to your home, as well as handling emergencies and outages.
An energy supplier, on the other hand, generates or purchases electricity from wholesale markets and competes to sell power to customers—offering different rates, contract terms, and renewable energy options. In Connecticut, you can choose your energy supplier for the “supply” portion of your bill, but your local utility remains responsible for delivery, infrastructure, and customer service.
CT Utility Companies
Connecticut is primarily served by two major utility companies: Eversource Energy and United Illuminating (UI).
- Eversource Energy serves approximately 1.2 million electricity customers in 149 of the state’s 169 cities and towns, with a new standard service rate of 9.748 cents per kWh from July 1, 2025, through the end of the year.
- United Illuminating serves about 335,000 customers in 17 towns and cities in the greater New Haven and Bridgeport areas.
These utilities play crucial roles in Connecticut’s deregulated market by maintaining the electrical grid, responding to power outages, delivering electricity to all customers in their service areas, and providing “standard service” rates for customers who don’t choose an alternative energy supplier. While you can’t select your utility company, if you live in the Nutmeg State, you can choose your electricity supplier through ElectricityRates.com to shop for better rates while still receiving reliable service from your local utility.
How to Change Electricity Providers in Connecticut?
- Grab Your Latest Bill: To switch, you need specific information from your current electricity bill. Locate your Account Number and your Name Key (usually a 4-letter code found near your account number). Having your bill also helps you see your current “Standard Service” rate so you can accurately compare it to new offers.
- Compare Rates on electricityrates.com Head to our electricity marketplace and enter your ZIP Code to be shown rates from top suppliers serving your area.
Pro Tip: Look for “Fixed” rates to avoid price spikes, and check the “Term” (length of the contract). Connecticut law prohibits residential suppliers from charging sign-up or early cancellation fees, so you can switch again later if rates drop.
- Enroll Online: Once you find a plan that fits your needs, click the “Select Plan” button. From there you will enter your account details and confirm the switch. There will be no service interruption to your electricity and the switch typically takes effect on your next scheduled meter reading date (usually within 1–2 billing cycles).
What to Look for When Selecting a Connecticut Electricity Plan
Choosing the right Connecticut electricity plan is a crucial decision that can significantly impact your energy costs. Below are a few of the key considerations to selecting a plan:
- Price per kWh & contract length: Compare CT electric rates and terms to get an apples-to-apples comparison.
- Fixed vs. variable: Fixed = steady, locked-in price; variable = can save, but rate may change (more info on types of plans in CT below).
- Early termination or hidden fees: Ensure you’re comfortable with the commitment.
- Green energy: Prefer eco-friendly plans? Look for 100% renewable plans.
- Provider reputation: Check the company history and customer reviews to avoid any unwanted shocks. We track top Connecticut electricity providers and pre-vet offers on our marketplace.
- Additional perks: Many energy suppliers offer new customer discounts or referral benefits.
Watch out for red flags, such as extremely low introductory rates that increase dramatically after a short period, pressure to sign up immediately without reviewing the terms, a lack of clear information about rates and fees, and unsolicited door-to-door sales or high-pressure phone tactics.
Remember, all suppliers listed on ElectricityRates.com are licensed by PURA, maintain high customer scores, and adhere to strict consumer protection guidelines. To find out more about top top-rated energy suppliers, head over to our Best Connecticut Electricity Providers page.

- Variable-rate plans: Month-to-month and flexible, but prices can jump without warning.
- Time-of-Use (TOU): Cheaper off-peak rates; great if you can shift laundry, EV charging, and dishwashing to less busy times in the day.

What is Energize CT?

Its “Home Energy Solutions” audit offers on-site assessments, free energy-saving products, and recommendations, saving homeowners $200-$250 annually.

Energy Choice Program in Connecticut
Since 1998, Connecticut has operated under a deregulated electricity market, thanks to Public Act 98-28. This Energy Choice program (known as electricity deregulation) has fundamentally changed how residents and businesses purchase their electricity. Under Energy Choice, the supply and delivery of electricity are separate. While your local utility still handles the delivery of electricity and maintains the infrastructure, you have the freedom to choose your CT electricity supplier.
The benefits of Energy Choice include potential cost savings, customized plans tailored to different needs, and innovation in energy products. The Public Utilities Regulatory Authority (PURA) plays a crucial role in overseeing the Energy Choice program by licensing and monitoring electricity suppliers, ensuring fair marketing practices, providing resources for consumer education, and addressing customer complaints and disputes.
