Opponents of Central Maine Power Co.’s current efforts to replace all its electric meters with “smart” meters have filed a formal complaint at the Maine Public Utilities Commission.

The complaint asks the PUC to order an immediate halt to installation and allow for new public input regarding the project. It also asks that customers who don’t want the meters installed be allowed to opt out of the program.

Smart meter opponents say the wireless, radio frequency equipment can affect human health and that the impact of installing the networks in neighborhoods needs further study. CMP and Maine’s public health agency said the techology is safe and similar to wireless routers  used to connect computers.

The filing was spearheaded by Elisa Boxer-Cook, a Scarborough resident. The action comes five days after the town of Scarborough became Maine’s first town to pass a resolution asking CMP for a 90-day halt to installation.
