Connecticut Light & Power Co rate plans

4 residential plans are currently open to new customers. Some charge different prices depending on the hour — which is where most of the savings hide.

Which plan would cost you least?

No bill upload, no sign-up. Tell us roughly what you use and what runs on electricity — we price every plan against the same household and show you the gap.

What else runs on electricity

That adds up to 7,914 kWh a year. Compare it to the total on your bill and adjust until it’s close.

Same usage, different plan

$531a year

That is the gap between the cheapest plan you could be on — Rate 18- Controlled Water Heating Electric Service — and the priciest. Not by using less power. By being billed differently for the same power.

An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
