Hawaiian Electric Co. customers on O'ahu, Maui and the Big Island may be saying goodbye to their meter readers.

The company has signed a 15-year agreement with a company that makes automatic meter-reading systems and hopes to deploy the wireless-reading equipment starting next year to 430,000 residential and commercial electric customers.

The company said that it decided to use the remote-reading solution made by Sensus Metering Systems after completing a two year test in which thousands of "smart" electric meters were deployed in a variety of settings on O'ahu.
