Guam Power Authority AMI Deployment

GPA realized a 9% increase in overall customer satisfaction with the utility and a 13% increase in satisfaction with GPA customer service since 2012.

Grid modernization programs are driving measurable increases in customer satisfaction at Guam Power Authority (GPA).

According to customer surveys conducted before and after installing advanced meters, GPA realized a 9% increase in overall customer satisfaction with the utility and a 13% increase in satisfaction with GPA customer service since 2012 – the year it began installing Landis+Gyr's Gridstream® AMI solution.

GPA’s improved customer satisfaction numbers are linked to improvements in outage response, line losses and customer transactions, such as new account set-up and final billing on terminated accounts.

"Customer satisfaction is influenced by a variety of factors, including how we managed billing changes after meter installations, and the improved efficiency of transactions for transient customers," said John Cruz, Manager of the Strategic Planning and Operations Research Division at GPA. "We've seen a sizable reduction in truck rolls for service calls and both technical and non-technical line losses. These efficiencies allow us to keep power costs lower and reduce connection fees. Customers are responding to service improvements overall."

With its advanced metering project now complete, GPA is expanding capabilities for managing distributed generation from solar installations, improving power quality with voltage management initiatives and analyzing AMI data for insights into distribution network performance to promote operational efficiencies.

Landis+Gyr's Gridstream platform provides a reliable and secure connection to critical points across the distribution system, and interfaces with existing utility systems and applications to more effectively manage billing, operations, engineering and customer engagement. The network component of the solution enables two-way communications with meters, sensors and switches to provide interval load and voltage data and support net metering, outage management and remote service connection capabilities.
