Reading your digital meter

The APS meter at your home tracks and records your daily power usage. You can check your daily energy usage1 by logging into your aps.com account online or on the APS app. Your online account provides detailed reports of your usage and is the best and easiest way to view and manage your usage. Some customers have an interest in learning more about how their meter works. The information on this page will help you understand how to read the usage on your meter, if you choose. See tips for reading each meter type below.

There are three categories of digital meters –
Standard Advanced Metering Infrastructure (AMI),
Solar AMI, and
Non-Standard Non-AMI2,
which are explained in each tab below.

The meters can measure total power you use over time in kilowatt hours (kWh), on-peak, off-peak, and super off-peak kWh and kW usage (demand). They feature an easy-to-read electronic display, which typically shows six to 12 fields. Each field appears through the display window for a few seconds on a rotating basis.

Note: Most APS meters are standardized to be consistent across display types for our time-of-use classifications, regardless of the rate plan you may be on. Therefore, you are only charged for the fields displayed on the meter, or time-of-use classifications (tiers), that apply to your rate plan. APS may use this non-billing data to compare your usage history to recommend rate plans that may save you the most money based on your usage habits.

The information provided on this page was prepared for you as a general guide. Please note that it does not apply to all meter models.
