SANFORD — Sanford has become the third Maine community to pass a resolution asking Central Maine Power Co. to hold off on installing smart meters.

The town council wants CMP to wait at least 90 days before installing more equipment, until the utility provides residents with more information.

Scarborough and Cape Elizabeth previously passed similar requests.

CMP is replacing all its electric meters with new wireless equipment meant to help manage electricity use and demand. But some residents have concerns, ranging from health impacts to privacy and security. CMP says the meters are safe and secure.

The Maine Public Utilities Commission also is reviewing a request from smart meter opponents to put the program on hold, but so far has taken no action.
