As a customer, you receive a monthly bill for your energy and water usage. If you have a smart meter, your usage information is automatically transmitted to EWEB using a low-power radio over a secure wireless network. If you have a non-communicating meter, our meter readers physically collect the energy and water usage information needed to calculate your bill each month.

While it is EWEB's intention to read every meter each month, there are occassions when we need to estimate a customer's usage due to various circumstances such as weather, technical difficulties, complications accessing the meter, or due to changes in staffing.

If we are unable to collect the actual meter read, standard business practice is to calculate an estimate of the amount of energy and water you used in that billing period. Although the frequency of estimations has temporarily increased, they are not new. Utilities often use estimations when they are unable to get to an actual read of a meter. 

How does EWEB estimate usage?

The meter on your home works like the odometer in your car, counting energy in kilowatt hours (kWh) and water in kilogallons (kgals). EWEB reads the meter and then subtracts the previous meter read to determine your usage for the month. All meter reads are printed on your bill.

When usage is estimated, the estimation calculation is based on the average of the prior month's usage, the same month last year and the prior month last year.

When actual usage is collected after an estimate, any difference between the prior estimation and your actual usage is automatically corrected. If our estimate was too low (your usage was more than we estimated), the difference between the estimated usage and your actual usage will be added to your next bill. If our estimate was too high (your usage was less than we estimated), you'll be credited on your next bill for the additional amount you paid.

Example April 2022 Estimated Bill  
Example May 2022 True-up Bill
March 2022 consumption 1600 kWh April bill based on estimated consumption 1400 kWh
April 2021 consumption 1400 kWh April Actual consumption 1500 kWh
March 2021 consumption 1200 kWh True-up difference (1500-1400)   100 kWh
Average  1400 kWh May Consumption 1000 kWh
Estimated April bill 1400 kWh Total May bill (actual consumption + true-up) 1100 kWh

To find out if your usage was estimated, view the Electric or Water Usage section of your bill. If your bill was estimated, you will see the note: *based on an estimated read. There will also be a note in the "message center" in the left margin of the first page of your bill. 

If your bill does not indicate it is an estimated bill, it may be the corrected (true-up) bill. You can verify this by looking at your previous bill to see if it inidicates that it is an esitmated bill.  The true-up bill is based on your actual meter read, when we correct any difference between your actual and estimated readings.
