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.

Multiple electricity suppliers compete for your business, offering various plans and rates. This competition is designed to drive innovation and potentially lower prices. Your local utility (Eversource Energy (formerly known as CL&P) or United Illuminating) continues to deliver electricity, maintain power lines, and respond to outages, regardless of your chosen 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.

What is Energize CT?

Energize CT is the statewide program that helps residents and businesses save through rebates, audits, and efficiency incentives—think smarter insulation, heat pumps, and weatherization that cut CT energy costs in the long term.

The program is funded by a utility bill surcharge, helps Connecticut residents and businesses reduce energy use and costs through programs and rebates. Its “Home Energy Solutions” audit offers on-site assessments, free energy-saving products, and recommendations, saving homeowners $200-$250 annually.

Energize CT offers a wide range of rebates for energy-efficient upgrades, including significant incentives for heat pumps, smart thermostats, and triple-pane windows. The initiative also provides specialized energy audits and rebates for businesses of all sizes.

Understanding Your Connecticut Electricity Bill

Deciphering your electricity bill is key to making informed decisions about your energy supply. Connecticut electricity bills typically consist of two main components: delivery charges and supply charges.

  • Delivery: Delivery charges are set by your utility company and regulated by PURA. TThey cover the cost of transmitting and distributing electricity to your home, including maintenance of power lines and other infrastructure in your town.
  • Supply: Supply charges reflect the cost of generating or purchasing electricity and can vary based on your chosen supplier and plan.
  • Additional Charges: Your bill may also include additional charges such as transmission charges (regulated by the Federal Energy Regulatory Commission, or FERC), distribution charges, public benefits charges, and Competitive Transition Assessment (CTA) charges.
Understanding the components of your Connecticut electricity bill

Pro tip: Your “Price to Compare” is the utility’s Standard Service supply rate. If a supplier’s electricity rate beats that (after fees), you likely save money on the usage portion of the bill.

Tips to Reduce Electricity Costs in CT

While choosing the right supplier through ElectricityRates.com can lead to significant savings, implementing energy-efficient practices can further reduce your electricity bill.

Practical strategies to reduce your Connecticut electric bill include:

  • Leverage Energy Choice to shop rates or take advantage of time-of-use rates
  • Perform regular maintenance on energy-consuming systems
  • Use natural light and heating/cooling
  • Monitor your monthly electricity usage and take advantage of free Energize CT audits
  • Upgrade home appliances such as LEDs and smart thermostats
  • Educate household members or employees about energy conservation
  • When CT energy prices change twice a year (January/July), compare Connecticut electric rates rates again.

By combining these energy-saving strategies with a competitive electricity plan from ElectricityRates.com, Connecticut residents and businesses can significantly reduce their energy costs while contributing to a more sustainable future.

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.

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:

  1. Price per kWh & contract length: Compare CT electric rates and terms to get an apples-to-apples comparison.
  2. Fixed vs. variable: Fixed = steady, locked-in price; variable = can save, but rate may change (more info on types of plans in CT below).
  3. Early termination or hidden fees: Ensure you’re comfortable with the commitment.
  4. Green energy: Prefer eco-friendly plans? Look for 100% renewable plans.
  5. 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.
  6. 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.

Types of CT Energy Plans

  • Fixed-rate plans: Lock in a CT energy rate for 6 to 36 months—popular for budget predictability.
  • 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.
  • Green energy plans: Match some or all usage with renewable energy, even if you don’t want to install solar panels. The perfect way to support a cleaner Connecticut community.

Renewable Energy in Connecticut

Connecticut’s power generation relies heavily on natural gas, accounting for 50% of its total energy production, while nuclear power makes up 40% of the state’s energy.

However, Connecticut has made significant strides in promoting renewable energy, offering residents more green options than ever before. The state has set ambitious goals through its Renewable Portfolio Standard (RPS), aiming for 40% of electricity to come from renewable sources by 2030 and a 100% zero-carbon electricity supply by 2040. These targets drive investment in renewable energy and increase the availability of green energy plans for consumers.

Business and Commercial Electricity Rates

All Connecticut business owners face the challenge of coping with high electricity costs. As of 2025, the average commercial electricity rate in Connecticut is approximately 22.92 to 23.34 cents per kWh, making it one of the highest commercial rates in the nation. Retail energy rates from competitive suppliers can offer substantial benefits for Connecticut businesses, including potential for significant savings, customized plans, budget certainty, and energy management solutions.

Business owners can choose from various types of electricity plans, including fixed-rate plans, indexed plans, block and index plans, and green energy plans. When selecting a plan, businesses should consider their usage patterns, contract length, demand charges, and additional services offered by suppliers.
