California is rapidly decarbonizing its electricity grid through increased reliance on decentralized production, storage and management of electricity use. To maintain reliable customer service in a more decentralized power grid, California’s grid operators are finding new ways to coordinate operations. The new practices are highlighted in a report released by MTS titled “Coordination of Transmission and Distribution Operations in a High Distributed Energy Resource Electric Grid,” prepared by the California Independent System Operator, Pacific Gas & Electric, Southern California Edison and San Diego Gas & Electric with MTS. The report describes the challenges of operating a high distributed energy resource grid, and recommends a number of new, proactive exchanges of information between CAISO, utilities, and DER service providers.
