According to the official tracker (https://www.energy.ca.gov/data-reports/clean-energy-serving-... and elsewhere) there were 279 days in 2025 where California was on 100% renewable for _some_ time during the day (could be hours, could be minutes at mid-day).
In total hours equivalent of 77.3 full days over 2025.
