California Community Choice Aggregators (CCAs) are pioneering long-duration energy storage (LDES) projects like Tumbleweed and Willow Rock to enhance renewable energy utilisation by storing excess solar and wind power. These projects aim to provide continuous discharge for 8+ hours, reducing curtailment, grid strain, and reliance on peaking fossil fuel plants while supporting state procurement goals.
