Central Maine Power Company's (CMP's) Advanced Metering Infrastructure (AMI) project featured territory-wide deployment of more than 622,000 smart meters, covering all of CMP's residential, commercial, and industrial customers. This project created a technology platform for providing customers with electricity usage information and alternative electricity rates from third-party energy providers. Customers view their energy consumption through a web portal and can use that information to help manage electricity bills. CMP assessed the load-shape and consumption impacts of providing customers with different types of information using web portals and proactive bill alert messages.
