Potomac Electric Power Company (PEPCO) Smart Grid Project

From Open Energy Information

Potomac Electric Power Company (PEPCO), located in Washington, District of Columbia, will receive $44.6 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected PEPCO as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

The Pepco Holdings, Inc.-DC (Pepco) Smart Grid project in Washington, DC, includes distribution automation, advanced metering infrastructure (AMI), and demand response programs that involve load control devices and time-based rate programs. The AMI installation is designed to provide customers and Pepco with detailed electricity usage information, which, when combined with the demand response programs, helps customers reduce electricity usage and peak demand. The distribution automation deployment includes automated distribution circuit switches and transformer monitors that improve the reliability of the distribution system while decreasing operations and maintenance costs.[3]
