Is this what you'll actually pay?
It's a fair benchmark, not a forecast. We take Connecticut's average rate of 32.24 ¢/kWh and apply it to 900 kWh a month at the all-in average rate, which comes to $290.16. That rate already includes delivery, fixed charges, and utility fees; locally billed taxes vary by area.
Your own bill can land well above or below that, depending on how much you run the air conditioning, how you heat your home and water, your home's size, and how your utility designs its rates.

Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
