Electric AMI Meter Project
Frequently Asked Questions
What is the Advanced Metering Infrastructure (AMI) Project?
The AMI project is a technological upgrade of all the electric revenue meters in Wellesley. This project involves installing new electric meters at all residences and businesses. The new equipment will allow us to provide improved service, operational savings and better energy usage / billing information.
What is an AMI meter?
AMI stands for Advanced Meter Infrastructure. AMI meter technology has existed for decades and is the most efficient and effective method for collecting and transmitting usage data and detecting service interruptions. AMI meters are digital electric meters equipped with wireless communication technology.
AMI will allow the WMLP to remotely read your electric meter data without having to drive by or access your property each month. The AMI meters will transmit your usage data remotely and automatically over a private, secure radio frequency (RF) network to the WMLP. AMI can also more readily detect power outages and send alerts, which will improve restoration times. Customers will also have the ability to access and review their electric usage on a web-based customer portal.
Why is the WMLP installing AMI meters?
Our existing meters are past their useful life and need to be replaced. The WMLP last replaced them in 1999. Since then, AMI meters have become the standard for utilities around the country because they allow for more efficient collection of meter readings and improved service, particularly in the event of an outage. According to the U.S. Energy Information Administration, about 73% of total residential electric meters in the U.S. are AMI. National Grid and Eversource will begin to deploy AMI meters throughout their service territories in MA in 2024 and 2025, respectively.
How does AMI benefit me?
Using the customer portal, you will have the ability to monitor your electric usage at a more timely and granular basis and therefore be able to save energy and manage costs more effectively. This data will also help us better address your questions and any issues you may have with your usage or an outage condition. In the future, AMI could provide customers additional opportunities to reduce their usage and electric bills more dynamically through high usage alerts, demand management/response programs, and time-varying rates, particularly as more electric vehicles and heat pumps are adopted. These opportunities would serve as an important element towards achieving the Town’s goal for greenhouse gas emission reductions.
Will I still need to call when my power is out?
AMI meters will automatically and remotely report the location of outages, but please don’t hesitate to call us, particularly if you can provide us any information regarding the cause, e.g., fallen tree or limb.
Will this meter replacement cost me anything?
No, there is no charge for the AMI meter and its installation. There will be no additional customer bill charges for this new technology.
When and who will replace my meter?
WMLP employees will be installing the new meters starting in December 2023. All installers will have a photo ID badge and drive clearly marked vehicles. Upon arrival, they will ring the doorbell at or knock on your front door prior to locating and replacing your existing meter.
If we cannot safely access your electric meter or it is located inside your home or business, the WMLP will leave a door hanger and need to schedule an appointment with you for the installation. For inside installation, an adult (18 years old minimum) must be present. The area around the electric meter must be accessible to the installer.
How long will it take to replace my meter?
The installation will take approximately 20 minutes.
Will my service be interrupted during installation?
Replacement will require a brief power outage that typically lasts less than one minute. We sincerely apologize for this short disruption in your electric service.
How will I know that my meter has been changed?
We will leave a door hanger indicating that we have replaced your meter.
Does the radio frequency (RF) from AMI pose a health risk?
AMI meters will not negatively affect your health. The RF emitted by these meters is intermittent and well below the limits set by the Federal Communications Commission (FCC). They represent no known health hazards and emit significantly lower exposure levels than most other typical devices that emit RF, such as cell phones, wireless routers, baby monitors and microwave ovens.
Will the AMI communication system interfere with my home, business or medical devices?
AMI meters do not adversely affect the stability or performance of home wireless networks. The radio transmissions operate in compliance with FCC Regulations to avoid interference with other electronic devices.
Will my account and usage information remain confidential?
Data collected and transmitted by AMI meters is protected by multiple layers of security to guard against unauthorized actions, breaches and tampering. Meters and the associated communications system are encrypted and equipped with security features to prevent unauthorized access.
Will WMLP be able to control anything in my house?
No, the WMLP’s access stops at the AMI meter.
Will the WMLP be able to tell what I am doing in the privacy of my home?
No, AMI meters collect and transmit only energy use data.
Will my new AMI meter make my bills higher?
No, AMI meters measure and record electric usage in exactly the same way as our existing meters. They will not cause your usage to increase or decrease. AMI meters have been tested under various conditions and show consistently accurate readings.
How will I know that you have my reading and not someone else’s?
Each AMI meter has a unique identifier number associated with your customer account that will be transmitted along with the meter reading.
