Navajo Tribal Utility Association Smart Grid Project

Jump to: navigation, search

Navajo Tribal Utility Association, located in Ft. Defiance, Arizona, will receive $4.99 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected Navajo Tribal Utility as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

The Navajo Tribal Utility Authority’s (NTUA) Advanced Metering Infrastructure (AMI) project deploys 28,000 residential smart meters and supporting communications and information technologies. The project provides automated meter reading, improved outage detection and response, power quality monitoring, and tamper detection capabilities. The communications system relays customer electricity data to NTUA, where the new meter data management system helps NTUA leverage the data to better manage peak demand, which results in reduced system-wide capacity needs, electrical losses, and operations and maintenance costs.[3]
