Explain my bill

Copy the figures off your bill and we will price it from the rates National Grid filed with the state — every charge explained in plain language, and every number citing the document it came from. Where the filed rates will not support an answer, we say so instead of estimating.

From your bill

Rate class

Printed near the top of the bill, as a service classification.

Billing period from

Electricity used (kWh)

The total for the period, not the daily average.

Peak demand (kW)

Only on demand-metered commercial bills. Leave blank otherwise.

Who supplies your electricity?

NYISO load zone

Where your service address sits. Supply prices differ by zone.

Municipality (optional)

Sets the local surcharge. Blank uses the default rate.

Nothing you type here is saved. There is no account, and no copy of these figures after the page reloads.

Joule Compass explains bills and checks them against published tariffs. It is not an engineering audit and not financial advice. A difference between our reading and your bill is a question worth asking your utility, not a finding against them.
