Read My Meter

Your electric meter shows how many kilowatt hours (kWh) you use. By reading it regularly, you can monitor your energy use.

Digital displays

TEP is replacing many of its older meters with newer, electronic models.  If you already have one of these new meters, the display will show a running total of kWh that have been used since the meter was installed. 

To determine how much energy you have used since your last billing period, subtract the reading shown on your previous bill from the figure displayed on the meter. Then, multiply the difference by the multiplier found on your electric bill. (This second step isn’t really necessary for most residential customers, whose multiplier is usually “1.” However, commercial meters may have large multipliers.)  

For example, subtracting a previous reading of 05620 from the reading displayed above (06312), then multiplying the answer by “1,” would show that you’ve used 692 kWh since your last reading.

Some of our new meters occasionally display a screen showing all possible character segments (see below). This “character check” is displayed only briefly before the typical kWh display is restored.

Manual displays

Your electric meter shows how many kilowatt hours (kWh) you use. By reading it regularly, you can monitor your energy use. The dials on your meter work much like a car odometer with the dial farthest to the right advancing the dials to the left.

Remember to always read your meter from right to left. This will minimize your chances of making an error. Note that dials A and C move clockwise while B and D move counterclockwise.

For example, look at the meter below, start with dial A on the right and read to dial D on the left. If the arrow is between numbers, record the smaller number unless the dial is between 9 and 0, then record 9.

Electric Meter

If the arrow is close to or exactly on a number, look at the dial to the right. If the arrow has not yet reached 0 then record the smaller number. For example the meter above shows a reading of 8367.

Once you have obtained your reading, subtract this read from the previous month's read and multiply the difference times the multiplier found on your electric bill.

For example, subtract last month's reading of 5509 from this month's reading of 5699, giving you your usage of 0190 kWh. Multiply 190 times the multiplier of 10 which equals 1,900 total kWh used.


What's a "kWh," and why is it important?

A "kWh" or kilowatt-hour, is 1,000 watt-hours, the standard measurement for electricity consumption. For example, a single 100-watt bulb will use up 1 kWh after 10 hours. At a kWh rate of $0.08, the cost to light that 100-watt bulb for 10 hours would be $0.08. To better understand your electricity usage, check out Energy Tips.

How does TEP arrive at my monthly kWh usage?

Your current month's kWh usage is calculated by subtracting the previous month's meter read from this month's meter read.

When does TEP read my meter?

Your current bill statement lists the date that your meter will be read the following month and the date that it was read for your most recent billing cycle.

How can I reduce my monthly bill?

Simple adjustments to your usage patterns and the installation of energy-efficiency devices can reduce your power service consumption and lower your electric bill. Our Energy Tips will show you how to be a power saver.

My electric bills vary a lot from season to season. How do I even them out?

Your energy usage will fluctuate with the seasons and can even vary from month to month. Our Budget Billing program eliminates the guesswork of monthly electricity bills by estimating your annual bill and allowing you to pay the same amount every month.
