Central Maine Power Company Smart Grid Project

From Open Energy Information

Central Maine Power Company, as a result of the American Recovery and Reinvestment Act of 2009, will receive $95.9 M in funding to develop a smart grid.[2]

Central Maine Power Company’s (CMP) Advanced Metering Infrastructure (AMI) project consists of territory-wide deployments of more than 600,000 smart meters to all of its residential, commercial, and industrial customers. This project is designed to create 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 can monitor real-time electricity demand and use that information to better manage peak loads. This project aims to reduce operations and maintenance costs and service restoration times for customers through quicker and more accurate location of faults and power outages. CMP plans to assess the load-shape and consumption impacts of providing customers with different types of information using Web portals and home area networks.[3]
