San Diego Gas and Electric Company Smart Grid Project

From Open Energy Information

San Diego Gas and Electric Company, located in San Diego, California, will receive $28 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected San Diego Gas and Electric as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

San Diego Gas & Electric’s (SDG&E) Grid Communication System (SGCS) project includes the installation of a fully integrated wireless communication system covering up to 90% of the utility’s customers. The project aims to enhance reliability and reduce outage durations and operations and maintenance costs. The project implements two-way communications and applications to: (1) allow SDG&E to integrate new advanced metering infrastructure and distribution automation equipment, and (2) provide increased system visibility and identify the scope and location of outages.[3]
