Project Summary:

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.

Equipment:

- 50,280 Smart Meters
- AMI Communication Systems
--- Meter Communications Network
--- Backhaul Communications
- Customer Web Portal
- Substation Automation Equipment for 7 out of 29 Substations
--- Substation Automation Communications Network
--- Digital relays
--- Transformer Monitors

Targeted Benefits:

- Reduced Meter Reading Costs
- Reduced Operating and Maintenance Costs
- Improved Electric Service Reliability and Power Quality
- Reduced Costs from Equipment Failures, Distribution Line Losses, and Theft
- Deferred Investment in Distribution Capacity Expansion
- Reduced Truck Fleet Fuel Usage
- Reduced Greenhouse Gas and Criteria Pollutant Emissions
