Compare plans with your own usage
Download your hourly usage from your utility (Green Button or CSV). Select the file here. The tool calculates each month of your real usage on each plan of your utility, hour by hour for time-of-use plans, and on a supplier offer if you type one.
How to get your usage file
- Sign in to your account on the website of your utility.
- Find the usage page (for example "Energy usage", "My usage" or "Usage details").
- Click "Green Button", "Download my data" or "Export". Select hourly or 15-minute intervals and the last 12 months.
- Save the file (XML or CSV) and select it above.
Many utilities offer Green Button data. A time-of-use plan needs hourly or 15-minute data. For a plan without time periods, daily data is also enough.
How the tool calculates
The tool adds the kWh of each hour into calendar months. For a time-of-use plan it puts each hour in the period of that plan (for example on-peak, off-peak or super off-peak) from the hours, the weekdays and the holidays in the tariff. Then the bill calculator of each plan calculates each month with today's rates, the riders and the options that you select. The tool uses only complete months, and each plan uses the same months.
The result shows what your usage of the last year costs on each plan at today's rates. It does not show future rates, and it does not include net metering (energy that your solar panels send to the grid), discounts or programs that change the bill.
