Smart Grid Project


The Guam Power Authority’s (GPA) Smart Grid project involves a territory-wide deployment of advanced metering infrastructure (AMI) and implementation of substation automation equipment, which includes circuit switches, capacitors, voltage regulators, fault indicators, smart relays, and equipment sensors. Customers can install devices that assist in managing electricity use and costs, including in-home displays and home area networks. The new AMI and substation automation technologies are intended to improve reliability and stability of GPA’s electric system, reduce operating costs, and accommodate future deployment of distributed generation.
