Connecticut price to compare
If you live in a deregulated area of Connecticut and don’t sign up for a specific energy plan, you are automatically enrolled in a plan from your utility company and charged a default rate, known as the Price to Compare (PTC). Energy providers often offer plans with lower rates than the PTC. Enter your ZIP code or call the number on your screen to explore your options.
Types of energy plans in Connecticut
You have the power to choose an energy supplier in Connecticut. But before you do, there are a few main plan types to know when shopping for energy. Your exact rate structure depends on your chosen plan, but it will fall into one of these categories.
- Fixed-rate plans: Your electricity rate remains constant for the duration of your contract, typically 12–36 months. If you terminate your contract early, you’ll have to pay an early termination fee (ETF). Check the Electricity Facts Label (EFL) to find out what fees you may be charged.
- Variable-rate plans: The price you pay for energy changes by month with variable-rate plans and depends on fluctuations in the market. You can cancel your plan at any time without penalty.
- Prepaid plans: In a prepaid plan, a type of no-deposit plan, you pay for energy upfront and receive alerts when your account balance needs to be replenished.
- Renewable energy plans: In Connecticut, energy suppliers are required to source a portion of their energy from renewable sources such as solar or wind power. Some companies offer renewable energy credits (RECs), while alternative electric suppliers source 100% green energy.
Understanding deregulation in Connecticut
Electricity deregulation began in Connecticut in 2000. Since then, customers have been able to either choose their electricity plans from an independent electricity supplier or stay enrolled with their area’s utility company. Not sure where to start? Use Choose Energy’s free marketplace to compare plans and rates in your area.
The deregulated energy market in Connecticut is managed by the state’s Public Utilities Regulatory Authority (PURA). The utility educates residents and businesses on options through its Energize CT program.
