WattPayoff compares what available rate plans would have cost based on your own usage, so you can spot potential savings. Now it keeps checking for you. Each month, automated monitoring analyzes your most recent 365 days of actual usage, calculates costs across active PG&E electricity rate schedules, and notifies you of the lowest-cost option. If another rate would have saved you money, see the estimated difference. If your current rate was already the lowest-cost option, get that confirmation too. You can also run a comparison whenever you want. WHAT YOU CAN DO • Compare rate costs side by side using your own usage history, including time-of-use and EV rate options. • Explore energy usage charts by day, month, year, last 365 days, lifetime, billing cycle, or a custom date range. • Review PG&E bills, billing periods, energy billed, rate schedules, and individual charges. • See energy received from the grid and energy delivered back—especially useful if you have solar. • Explore modeled EV rate and Powerwall scenarios. • Use the app on iPhone or iPad. Whether you charge an EV, have solar or battery storage, or simply want a clearer picture of your electricity costs, PG&E Toolkit - Pro helps you make sense of your usage and rate options. To get started, you need PG&E electric service and access to your PG&E online account. Rate comparisons show what different plans would have cost for past usage. Rate eligibility and future savings may vary. SUBSCRIPTION PG&E Real Meter Data Analyses is a monthly, auto-renewing subscription. The current price is shown before purchase.

If you’ve ever tried to figure out which rate plan from PG&E is the most beneficial for your situation this is the app for you. I spent much time on my own trying to calculate the best rate plan for me. This app does it for me effortlessly after sharing data from my PG&E account. When I contacted customer support about the inclusion of the medical baseline in its calculations, they said they would look into it. Lo and behold, they implemented the medical baseline into the appropriate rate plans within literally minutes (as an option in account settings). Now that’s what I call excellent customer service! -- Kenzo Chan, 2025-09-29 ### *---- "Prior version was an App. Not sure what this." This app is barely functional and once you sign up it’s quite difficult to cancel your account.
