Matteo De FeliceI created this visualisation using 15-minute CAISO data from January 2023 to December 2025 to explore how batteries operate in relation to wind & solar generation and overall grid demand.
Each dot is a 15-minute snapshot. The X-axis shows combined wind & solar output (GW), the Y-axis shows battery net output (positive -> discharging into the grid, negative -> charging). Color encodes grid demand. It is quite evident the solar fingerprint and how demand shapes the dispatch.
