How to Obtain Your Electric Usage Data


With the advent of PG&E’s Smart Metering system, it is now possible to obtain data about your electric usage over the past years. When designing a solar system, it is important to have accurate information about your historical electric usage. Along with considering your future plans, your historical energy usage data is required to properly forecast your needs. Without it, you will almost certainly end up buying, and thus paying for, more solar systems than you need or not getting enough to obtain the saving you desired.

To obtain your historical energy usage data, you can simply contact us via phone at +1 (408) 900-8140 or email us at AnalyzeMyData@Sum.Solar.

If you prefer, you can download the data yourself by following the instructions outlined below. If you already have a PG&E account, skip to step 2.


Step 1: Set up a PG&E Account

If you DO NOT
have a PG&E account


  1. If you do not have a PG&E account, it is easy to set one up. First, you will need a copy of your PG&E bill (you will need your account number located on the bill).

    Click on www.pge.com to go to the PG&E website.

    After you see the login dialog box, click back on this tab to continue with the instructions and click the Next Step button.

  3. On the Verification screen, click the “Residential” button. Enter your 11-digit PG&E account number (located on your bill) and select the verification mode (phone number or SSN). Continue following the on-screen instructions and read and accept the Terms of Use.

    Next Step...
  4. You will see a “Download my data” pop-up or “Export your Data” dialog with a Time Period and Format selection. It will look either like this:

    PG&ampE Export Data Popup

    Or like this:

    PG&ampE Export Data Dialog

    Either way, select “Export Usage for a range of days”. Enter the “From” date to include at least 1 year of data. You can simply set the year back a couple of years to get more than 12 months of data (or the last full year that you were a PG&E customer). The more data you can provide, the more accurate the analysis can be. The easiest way to change the date is to click the mouse just to the right of the year, press backspace to earase the year, and type in a year at least one year ago.

    The “To” date should already be set to a couple of days prior to the current day (i.e. the most recent utility reading taken).

    Check the “CSV” radio button under Format.

    Click the Export button to download the data.

    Your file will begin downloading. You may get a save file dialog. In which case simply select "Save File" and press OK.

    Next Step...
  5. Unfortunately we have to do basically your last step again to get cost information. After clicking the “Export” button in the prior step, select the “Export all bill totals” radio button and click “Export” again.

    Your file will begin downloading. You may get a save file dialog. In which case simply select "Save File" and press OK.

    Next Step...
  6. You will end up with two files. One named “BillingData.ZIP” and one named “DailyUsageData-DATE.zip”. Note: The filenames may be slightly different but you can safely assume that the first two files in the download folder/list are the ones you just downloaded.

    Depending on your browser and your settings, your file will be downloaded to your USER\Downloads folder. Again, depending on your browser, you can typically open this folder by clicking on the down-arrow to the right of the filename at the bottom of the browser or the down-arrow to the right of the URL/Search Entry box at the top of the browser.

    Browser Download File Dialog

    Either way, click on the down arrow and select “Open Containing Folder” or “Show in Folder” (Note: if you are using Firefox, you will need to right-click on the filename that appears when you click on the down-arrow).

    Next Step...
  7. Simply e-mail the files to AnalyzeMyData@Sum.Solar. To do this, simply click on the AnalyzeMyData@Sum.Solar and then select both files and drag-and-drop the files into the message body of the email.

    Please make the e-mail title/subject: “Your Address” (i.e. 1234 Anytown, BigCity CA 91234).

    If you have any questions or need any assistance, please do not hesitate to call us at +1 408.900.8140. One of our operators would be happy to walk you through the steps.
