"As a result of the increase in WWS supply and decrease in demand from 2019 to 2024, the daily-average gap between WWS supply and demand decreased gradually during that period. This culminated March 7 to June 30, 2024, when the 24-h average WWS supply reached 61.3 % of demand, versus 56.1 % of demand during the same period in 2023." Also "peaked at 83.2 % of daily demand on May 25." Note that demand in 2023 was 533.6 Gwh/day and went down to 529.1. "between June 2023 and June 2024, nameplate capacities of utility solar, wind, and batteries increased by ∼18%, ∼4%, and 73.3%, respectively" Cost and details of those capacity increases isn't mentioned but it seems that the average 31.7% increase in capacity only yielded a 5.2pp increase (mostly from the batteries which appear to handle 4 hours of load).
