How to interpret this bill estimate

The statewide residential rate in Connecticut is 28.30 ¢/kWh. Applying that rate to 900 kWh of monthly use produces an estimated bill of $254.70 before delivery charges, taxes, and fixed utility fees.

That benchmark is useful for comparing states, but real households can land above or below it depending on cooling load, heating type, home size, appliance intensity, and local utility rate design.

What usually moves a household bill?

In practice, the biggest bill drivers are air conditioning, space heating, electric water heating, laundry, EV charging, and the length of time high-wattage appliances run each month.

That is why this page links to both usage-cost routes and appliance operating-cost pages: one shows what a whole-home kWh pattern looks like, and the other shows how specific devices contribute to the final bill.
