WattPayoff features
Everything the app does with your PG&E smart-meter data, one page per feature.
Compare every PG&E rate plan with your own usage
WattPayoff takes your actual hourly usage from PG&E and calculates what it would have cost on each currently offered PG&E residential rate plan, side by side, for the last 365 days or any range you pick.
A monthly check for a cheaper rate plan
Yes: every month WattPayoff prices your most recent 365 days of actual usage (or all the history available, if less) on every current PG&E residential rate plan and sends you a notification.
Usage charts at any scale
WattPayoff charts your PG&E smart-meter usage at the scale you choose: one day, one month, one year, the last 365 days, your lifetime with the app, a single billing cycle, or a custom date range.
Every charge on your PG&E bill
WattPayoff shows each of your PG&E electric bills line by line: the bill amount, billing days, energy billed in kilowatt-hours, your rate schedule, and every individual charge and tax, grouped by date range.
One billing cycle at a time
In WattPayoff, open your recent bills and choose a billing cycle; the app analyzes exactly the dates PG&E billed you, so the usage matches the bill.
Solar energy in and out of the grid
WattPayoff charts the net energy your home received from the PG&E grid and the net energy it delivered back, from your PG&E meter data, by day, month, year, billing cycle or custom range.
One or two Powerwalls, modeled
WattPayoff models your own PG&E usage with one or two Tesla Powerwalls on EV rate plans such as EV2-A and EV-B, and shows what each combination would have cost next to your current plan.
Rate plans for EV owners
WattPayoff prices your real usage, charging included, on the EV plans EV2-A and EV-B, the Electric Home plan E-ELEC and the time-of-use plans, and shows which would have cost least over the last 365 days.
