[ARCHIVED] Electric Metering System Upgrade

Wellesley Municipal Light Plant Logo

The Wellesley Municipal Light Plant (WMLP) is upgrading its electric metering system to improve electric service to residents and businesses. 

 This upgrade includes installing a new AMI (Advanced Meter Infrastructure) electric meter at your home or business. The installation will be performed at no cost to you.  

Instead of requiring the WMLP to drive by your home or business each month to collect readings from the electric meter, the new AMI electric meters will transmit data is transmitted remotely and automatically to the WMLP.

The new meters also give customers the ability to access and review their electric usage on a web-based customer portal, and can readily detect power outages and send alerts, which will improve restoration times. 

WMLP staff will begin installing  AMI meters in December 2023. Here's what to expect for the installation: 

  • Installers will arrive at your home or business in clearly marked vehicles and with a photo ID badge.
  • Installers will ring the doorbell or knock on your front door prior to locating and switching your existing meter. 
  • The installation will take approximately 20 minutes and will require a brief power outage that typically lasts less than one minute.  We sincerely apologize for this short disruption in your electric service.

If WMLP cannot safely access your electric meter, or it is located inside your home or business, WMLP staff will need to schedule an appointment for the installation.AMI Code (002)

For inside meter installation, an adult (18 years old minimum) must be present.  The area around the electric meter (minimum 5-foot radius) must be accessible to the installer.

For detailed information on the new AMI system, visit the WMLP AMI webpage at  Or contact WMLP Customer Service at Customer Service at 781-235-7600 or scan the QR code in this announcement. 

Thank you for your cooperation and understanding with this transition.
