Connecticut residents often search for the lowest electricity rates, but finding the right electricity plan requires more than choosing the smallest number displayed in a supplier advertisement.
Electricity bills can include multiple components, including electricity supply charges, delivery charges, public benefit programs and other regulated costs. Consumers who want to compare Connecticut electricity rates need to understand how supplier pricing works, how utility rates are calculated and how contract terms affect long-term costs.
Connecticut has a competitive electricity supply market where eligible customers can choose an electricity supplier while their utility continues delivering electricity and maintaining the local grid.
The Connecticut Public Utilities Regulatory Authority (PURA) provides consumer resources for choosing suppliers, comparing rates and understanding available electricity options.
A smart electricity comparison should consider:
Current utility supply rate
Electricity usage
Supplier pricing
Fixed or variable contracts
Monthly fees
Early termination charges
Renewable energy options
Renewal conditions
The cheapest advertised rate is not always the cheapest electricity plan.
How Electricity Choice Works in Connecticut
Connecticut separates electricity supply from electricity delivery.
Your local electric utility remains responsible for:
Power distribution
Utility poles and wires
Metering
Infrastructure maintenance
Outage restoration
An electricity supplier provides the generation supply portion of your bill.
This means switching suppliers does not change the company responsible for delivering electricity to your home.
The two major electric distribution companies in Connecticut are:
Eversource Energy
United Illuminating (UI)
Both utilities provide standard service generation rates, while eligible customers may compare alternative supplier offers through Connecticut's official supplier comparison resources.
Understanding this difference is important:
Utility = delivers electricity
Supplier = provides electricity supply pricing
Start With the Connecticut Supplier Rate Board
Before choosing among Connecticut electricity suppliers, consumers should understand the official comparison tools available.
The Connecticut Supplier Rate Board allows customers to compare supplier generation rates with utility standard service rates.
Consumers can use the official resource to compare electricity supplier rates and review available generation offers.
The correct comparison process is:
Identify your utility.
Check the current standard service rate.
Review available supplier offers.
Compare contract terms.
Calculate your expected annual cost.
This prevents consumers from choosing a plan only because of an attractive advertised rate.
Why Connecticut Electricity Rates Differ
Electricity prices vary depending on several factors:
Utility territory
Supplier offer
Contract length
Market conditions
Electricity consumption
Rate structure
A customer served by Eversource may see different standard service pricing compared with someone served by United Illuminating.
The Connecticut Supplier Rate Board explains that standard service generation rates change periodically, including scheduled changes during the year.
Because of these differences, there is no single Connecticut electricity rate that applies equally to every household.
Compare Connecticut Electricity Rates Based on Your Location
Electricity supplier availability depends on where you live.
Your ZIP code helps determine:
Utility territory
Available suppliers
Applicable rates
Current comparison options
Consumers can compare Connecticut electricity rates through available comparison tools and then evaluate plans based on their own electricity usage.
You can also compare electricity plans after identifying the offers available for your location.
A statewide average rate is useful for general understanding, but your actual service address determines which plans you can select.
Do Not Choose an Electricity Plan Only by the Advertised Rate
One of the most common mistakes consumers make is selecting a plan based only on cents per kilowatt-hour.
Consider two electricity plans:
Plan A
Rate:
12.5¢ per kWh
Monthly fee:
$0
Plan B
Rate:
11.3¢ per kWh
Monthly fee:
$14.95
At 1,000 kWh:
Plan A:
1,000 × $0.125 = $125
Plan B:
1,000 × $0.113 = $113
Add monthly fee:
$113 + $14.95 = $127.95
Although Plan B advertises a lower electricity rate, Plan A would cost less in this example.
This is why consumers should compare the total estimated electricity cost rather than focusing on one number.
Calculate Your Real Electricity Cost
A simple electricity cost calculation is:
Monthly electricity cost = electricity usage × supplier rate + additional fees
Example:
Monthly usage:
900 kWh
Supplier rate:
11.8¢ per kWh
Monthly fee:
$9.95
Electricity cost:
900 × $0.118 = $106.20
Add fee:
$106.20 + $9.95 = $116.15
This calculation provides a clearer picture of what the electricity plan may actually cost.
Always perform this calculation before switching suppliers.
Use Your Actual Electricity Usage
Your electricity consumption plays a major role in determining which plan provides the best value.
A small apartment may use:
400–700 kWh monthly
A larger home may use:
1,200–2,000+ kWh monthly
A plan that works well for one household may not work well for another.
Before choosing a supplier, review previous electricity bills and identify:
Average monthly usage
Highest usage month
Lowest usage month
Seasonal changes
A plan advertised around 1,000 kWh may not represent your actual electricity cost if your household normally uses much more or less energy.
Fixed-Rate Connecticut Electricity Plans
Fixed-rate electricity plans provide a stable supply rate for a specific contract period.
Common contract lengths include:
6 months
12 months
24 months
36 months
Advantages:
Easier budgeting
More predictable supply costs
Protection from certain market changes
However, fixed-rate does not mean your entire electricity bill remains unchanged.
Your bill can still increase because of:
Higher electricity usage
Delivery charges
Utility-related adjustments
Before choosing a fixed plan, review:
Rate per kWh
Contract duration
Cancellation fees
Monthly charges
Renewal terms
Variable Electricity Plans in Connecticut
Variable-rate electricity plans allow the supplier price to change according to contract terms.
These plans may provide flexibility but can create uncertainty.
Before selecting a variable plan, understand:
How often rates can change
What factors influence pricing
Whether notice is provided
Whether cancellation fees apply
PURA provides consumer guidance explaining how customers can review supplier choices and compare available electricity rates before enrolling.
A low introductory variable rate should not automatically be considered a long-term bargain.
Compare Eversource Electricity Rates
Eversource serves a large number of Connecticut electricity customers.
Consumers should compare Eversource standard service rates with available supplier offers before making a decision.
Eversource explains that the supply portion of the electricity bill represents the cost of electricity used by customers and that supply rates are based on market conditions.
When comparing Eversource alternatives, evaluate:
Supply rate
Contract length
Monthly fees
Cancellation charges
Renewable options
A supplier offer should always be compared against the current Eversource standard service rate.
Compare United Illuminating Electricity Rates
United Illuminating customers can also compare available electricity supply options.
UI publishes standard service generation rates and time-of-use pricing information for residential customers.
Before switching, compare:
Current UI supply rate
Supplier offers
Usage pattern
Contract conditions
The lowest advertised supplier rate may not always create the lowest overall electricity cost.
Understand Connecticut Delivery Charges
Many consumers compare only the supply portion of their bill.
However, electricity bills contain multiple components.
A supplier mainly affects the electricity supply portion.
Utility delivery charges continue because the utility maintains the physical electricity network.
This means:
A 10% lower supplier rate does not necessarily reduce the entire electricity bill by 10%.
Understanding each bill component helps consumers estimate realistic savings.
Check Monthly Supplier Fees
Monthly fees can significantly affect electricity costs.
Example:
Monthly supplier fee:
$14.95
Annual cost:
$14.95 × 12
= $179.40
A supplier plan must create more than $179.40 in annual savings through its lower rate before the fee becomes worthwhile.
Always convert monthly charges into yearly costs.
Review Early Termination Fees
Some electricity contracts include cancellation charges.
These fees matter if you:
Move homes
Find a cheaper plan
Want more flexibility
Need to change suppliers
Example:
Monthly savings:
$8
Annual savings:
$96
Termination fee:
$150
The cancellation cost could eliminate the expected savings.
Always review contract terms before enrollment.
Compare Renewable Electricity Plans
Some Connecticut electricity suppliers offer renewable energy options.
Consumers interested in renewable electricity should compare:
Renewable percentage
Electricity rate
Contract length
Monthly fees
Cancellation conditions
Renewable energy should be considered as one feature of the plan.
The most environmentally focused plan is not always the cheapest, and the cheapest plan is not always the best match for every consumer.
Avoid Promotional Electricity Rates
Some suppliers advertise:
Introductory discounts
Limited-time rates
Special promotions
Before choosing a promotional offer, check:
How long the discount lasts
What happens afterward
Whether the rate becomes variable
Whether additional fees apply
A promotional rate should always be evaluated across the full contract period.
Compare Annual Electricity Costs
Monthly comparisons can hide important differences.
Annual calculations provide a clearer picture.
Example:
Plan A:
$115 monthly average
Annual cost:
$1,380
Plan B:
$105 monthly average
Monthly fee:
$15
Annual energy cost:
$1,260
Annual fee:
$180
Total:
$1,440
Plan B appeared cheaper monthly but costs more annually.
Annual comparison helps identify the real value.
How to Switch Electricity Suppliers in Connecticut
The switching process is generally simple:
Step 1:
Review your current electricity bill.
Step 2:
Identify your utility and current supply rate.
Step 3:
Compare available supplier offers.
Step 4:
Review contract terms.
Step 5:
Enroll with your selected supplier.
The utility continues delivering electricity while the supplier provides the chosen generation service.
Consumers can review official Connecticut supplier selection guidance before switching.
When Should You Compare Connecticut Electricity Plans?
Good times to review electricity options include:
Before your contract expires
After receiving renewal information
When supplier rates change
When moving homes
After major changes in electricity usage
The electricity plan that worked last year may not remain the best option forever.

Avoid these mistakes:
Choosing the lowest advertised rate
The lowest rate may include hidden conditions.
Ignoring contract length
Short promotional plans may expire quickly.
Not checking renewal terms
Rates can change after the initial agreement.
Ignoring monthly fees
Small charges can create large annual costs.
Comparing supplier rates incorrectly
Compare supply charges with supply charges—not total bills with supplier-only rates.
