San Diego Gas & Electric's (SDG&E's) Grid Communication System (SGCS) project involved the installation of various wireless communication systems. These systems cover targeted intelligent electronic devices on transmission and distribution poles and other electric assets. SDG∓E implemented advanced high-speed wireless communications systems, updated and expanded supervisory control and data acquisition (SCADA) capabilities, and increased the communications fiber footprint, allowing the utility to remotely monitor, communicate with, and control transmission and distribution equipment. The project made critical communications upgrades at substations and supporting telecom sites. SDG&E also expanded and optimized communications infrastructure to support smart grid initiatives while increasing system resilience.
