SDG&E Grid Communication System


San Diego Gas & Electric’s (SDG&E’s) Grid Communication System (SGCS) project includes the installation of an integrated wireless communication system. The network covers targeted intelligent electronic devices on transmission and distribution poles and other electric assets. The project is making critical communications upgrades at substations and supporting telecom sites, expanding and optimizing the communications infrastructure to support Smart Grid initiatives while increasing system resiliency. The project aims to enhance reliability and reduce outage durations and operations and maintenance costs. SGE&E is implementing two-way communications and applications to (1) allow for the integration of new distribution automation (DA) equipment, (2) provide increased system visibility and identify the scope and location of outages, and (3) prepare for more intelligent end-point devices that support new forms of electric generation such as wind and solar. SDG&E is implementing advanced high-speed wireless communications systems, optimizing and expanding SCADA, and increasing the communications fiber footprint that will allow the utility to remotely monitor, communicate with, and control transmission and distribution equipment. Additionally, the project will improve grid security, reduce operating costs, improve grid resilience, and support future Smart Grid technologies.
