Advanced Metering Infrastructure (AMI) is being deployed by utilities in the US to give distribution network operators better tools to manage the network.

On October 25, Landis+Gyr and Arizona Public Service (APS) said they are expanding their contract, originally signed in 2015, to include additional AMI services plus the installation of an additional 500,000 advanced meters over the next seven years.

APS, which serves 1.3 million homes and businesses in Arizona, has begun deploying Landis+Gyr’s Gridstream AMI infrastructure in 2016 and has used the network to support advanced metering technology and distribution automation across its service territory, according to a press release.

The Gridstream network connects utilities with data from critical points in the distribution system and interacts with existing utility systems and applications to more efficiently manage billing, operations, engineering and customer service.

The network enables communications with meters, sensors and switches to provide load and voltage data at intervals and enables network metering, outage management and remote service connection capabilities, according to the company.

“As we look forward to new opportunities for distributed energy resources and growth in electric transportation, the data and control provided by smart grid systems play a critical role in the planning, management and maintenance of our electric grid,” said Scott Bordenkircher, Director of Metering Technologies in APS.
