Memphis Light, Gas and Water Division Smart Grid Project
Memphis Light, Gas, and Water Division, located in Memphis, Tennessee, will receive $5 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected Memphis Light, Gas, and Water Division as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.
Memphis Light, Gas, and Water Division’s (Memphis’s) project to implement smart grid technology in a network electric distribution system includes new intelligent relays and sensor equipment to provide remote switching at the transformer level and information to aid in the design, operation, and preventive maintenance of this complex electric system. A fiber optic communications system is being deployed, which integrates real-time data from grid monitors with the grid operator’s distribution management software platform. Memphis expects these upgrades to reduce restoration times and the need for truck rolls for grid maintenance, improving reliability and reducing operating costs and pollutant emissions.
