AUGUSTA — Maine utility regulators are going to investigate Central Maine Power Co.’s Smart Meter installation policy.

The Public Utilities Commission voted today to open an investigation to determine if a policy of providing a no opt-out option in the Smart Meter program is reasonable or unjustly discriminatory.

Smart Meters were approved by the PUC in early 2010. The system is designed to improve customer service, enhance storm restoration efforts, reduce utility costs and ratepayer costs.

The commission decided today to examine the possibility of local opt-outs to the program and what alternatives are available.
