PORTLAND — A group of Central Maine Power ratepayers has filed an appeal with the state’s highest court in its fight against the utility’s use of smart meters.

Lead plaintiff Ed Friedman and other CMP customers are appealing the Public Utilities Commission’s dismissal of their complaint challenging CMP’s program to replace 600,000 traditional electric meters with wireless digital devices known as smart meters.

The appeal filed with the Maine Supreme Judicial Court claims smart meters can create health problems and are an invasion of privacy because information they collect can be used for personal profiling.

CMP says smart meters are safe, cut energy use and allow utilities to pinpoint problems during power outages more quickly.

The PUC allows CMP customers to opt out of using the meters for $12 a month.
