Exploration of the integration of renewable resources into California's electric system using the Holistic Grid Resource Integration and Deployment (HiGRID) tool

► Modeled interaction of renewables resources on California grid. ► “True” cost of intermittent renewables must include effect on other generation. ► Value of dispatchable power increases with additional intermittent renewables. ► Integrating wind and solar exhibits synergistic benefits for cost and performance.
