Energy storage of the right size installed at strategic locations can optimize load and effectively reduce wires infrastructure build-out across all voltage levels (e.g., circuits, substations, subtransmission). Energy Storage deployed at strategic locations for capacity benefit and enhanced with a MicroGrid capability can serve a dual purpose of peak shaving during normal conditions and maintain electric service to the customer(s) during planned or unplanned outages. Determination of right size and strategic location for energy storage deployment relies on the accuracy of the grid data, such as connectivity model. Southern California Edison’s Grid Connectivity Model (GCM) is the definitive source for up-to-date electrical connectivity and structural data of the SCE grid. This ensures that system planners, engineers, and operators have consistent information for their analysis and planning. GCM services are available to the enterprise to better model the system and are essential for integrating clean energy and customer-side alternatives. Each panelist will provide a different perspective as theyoutline SCE's approach to evaluating the strategic deployment of battery storage, the factors influencing decision-making, and examples of deployed energy storage. Additionally, the panel will dive deeper into the GCM framework, challenges and solutions for overcoming data quality challenges.
