Smart Grid Project


The Guam Power Authority's (GPA's) Smart Grid Project involved a territory-wide deployment of advanced metering infrastructure (AMI) and integration of the AMI with an outage management system (OMS). GPA also implemented substation automation equipment including voltage regulators, fault indicators, smart relays, and transformer monitors. An energy management system was deployed to leverage the new automation assets. Customers now have the ability to install devices that assist in managing electricity use and costs, including in-home displays and home area networks.
