Detroit Edison Company Smart Grid Project

Jump to: navigation, search

The Detroit Edison Company, located in Detroit, Michigan, will receive $83.8 million in federal funds to develop a smarter energy grid. The U.S. Department of Energy chose Detroit Edison as one of 100 companies nationwide to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

Detroit Edison’s (DTE) SmartCurrents project includes deployment of distribution automation assets, advanced metering infrastructure (AMI), and various customer systems. Distribution automation includes 55 circuits and 11 substations upgraded with automated switches and monitors a voltage ampere reactive (VAR) control. AMI includes 600,000 smart meters with customer systems including in-home displays, smart appliances, and programmable communicating thermostats (PCTs). A time-based rate program pilot will assess demand response and customer acceptance. Overall, the project improves distribution system reliability, operational efficiency, and power quality, and assists customers to make more informed decisions about electricity usage to control costs and bills.[3]
