The purpose of this report is to provide insight into utility trends regarding AMI deployment costs and benefits within the NEEP region. The report reviews the costs and benefits evaluated in both retrospective and prospective AMI deployment proposals, highlighting any outlying factors included in each proposal. There are a wide range of functions offered by an AMI system that enhance the information available to the customer, increasing the potential for interaction between the customer and utility. The customer is able to become a more active participant in the market for electricity and can change the way they use electricity. The utility is able to provide new programs and rate designs that incentivize more efficient use of electricity. The economic and social benefits of these changes are widespread and differ according to the functionality proposed in various AMI deployments.
