Smart Meter FAQ
Find answers to frequently asked questions about smart meters below. If you have additional questions, our customer service team is available 24/7 at (602) 236-8888.
Smart meters are equipped with two-way radio communication, which enables SRP to read them remotely, start and stop power remotely in most cases, and change price plans for customers without having to change the meter.
Smart meters securely capture and store energy-usage data using digital technology. SRP then provides the information through online tools such as SRP My Account and the SRP Power app, giving customers better control over their energy usage and budgets.
Because smart meters do not require manual meter reads, they offer a number of additional benefits such as helping to lower prices through reduced transport, fuel and labor costs, in addition to helping reduce pollution and traffic in our communities.
SRP's smart meters are manufactured by Honeywell Smart Energy (formerly Elster) and Landis+Gyr.
SRP installed its first smart meters in 2003.
Some people have asked about the potential health effects from exposure to the radio frequency (RF) emitted by smart meters.
Although smart meters utilize RF technology, they represent no known health hazards and emit significantly lower exposure levels than most other typical devices that emit RF, such as cellular phones, wireless routers and microwave ovens. For more details on the subject, please download Honeywell Elster's white paper on RF safety .

Smart meters provide a number of benefits to customers; however, if you wish to have an alternative meter installed at your residential location, and there are no meter access issues or on-site generating devices present, you can choose to opt out by calling SRP at (602) 236-8888. With this option, SRP will switch you to the Basic Price Plan and install a standard meter, which must be read manually. This will require an additional monthly charge of $20 plus tax, which helps recover additional costs for bill processing and the costs associated with manually reading the meter.
SRP will manually read your meter every other month. On the months we do not read your meter, your usage will be determined based on prior history. SRP will correct any potential discrepancies with the next month's read. If no usage history is available, SRP will continue to manually read the meter until enough history has been accumulated. Any variance or correction will be made the next time your meter is read.
While many programs are available to Basic Price Plan alternative customers, some programs are not supported by the limited technology of a standard meter. SRP customers who opt out of having a smart meter will not be able to enroll in Time-of-Day price plans, Renewable and Buyback riders, M-Power or Custom Due Date.
Not at this time, however SRP remotely reads the meter daily and posts the reads and usage in My Account for you to view and more easily manage your energy usage.
Our smart meters are designed, built and tested to comply with American National Standards Institute (ANSI) standards C12.1 and C12.20, which call for metering accuracy of +/- 0.5% at temperatures ranging from -40° F to 176° F. Every meter is tested by the manufacturer for accuracy prior to shipment, and the meter test results are then forwarded to SRP.
When smart meters are received by SRP, a sample of the shipment is tested to confirm the accuracy results. SRP follows the rigorous statistical sampling standards established by ANSI, and the testing protocol provides for very clear pass/fail criteria.
SRP systematically monitors the consumption and diagnostic data reported by the meters on a daily basis. We also continuously monitor the status of the communications network.
SRP also performs billing validation routines that identify when usage falls outside expected parameters. If a bill falls outside these parameters, SRP will validate and/or correct the bill before it is issued.
Customers may also validate their meter reads by verifying the meter reads at the physical meter or by tracking their daily energy consumption on SRP My Account. See instructions on how to read the smart meter.
Yes, smart meters are secure. Protection begins at the meter itself. Proprietary meter protocols defend against hacking. Encryption is used at each step of the data transmission process: at the meter, during transit from the meter to SRP, and at SRP. The meters are password-protected and meet the ANSI 12.21 and 12.22 security standards for communication. The equipment SRP uses is completely removed from the broad internet. SRP uses a separate system with firewalled access to the outside world.
SRP has skilled personnel in place to monitor emerging standards, risks and threats, and procedures are adapted to ensure compliance with existing and emerging standards and requirements.
As an added precaution, every meter reading used for billing is systematically tracked for extreme variations in reads — very high or very low usage in any one billing period.
