Peak electricity demand tends to be in the afternoon, right around sunset. Since this is right as solar is tapering off, this creates the duck curve problem [1]. It does vary by region and season. In hotter climates, during the summer, peak electricity demand does tend to happen around mid-day [2]. The same page you linked, actually. In case you didn't notice, the demand curves for spring, summer, fall, and winter are all overlaid on the same graph. Mid-day electricity use is highest during the summer, but in other seasons it peaks in the evening right around sunset. Furthermore, about half of homes in the US are heated by gas [3], so decarbonization of heating is going to increase night-time energy use. 1. https://en.wikipedia.org/wiki/Duck_curve https://en.wikipedia.org/wiki/Duck_curve 2. https://www.eia.gov/todayinenergy/detail.php?id=42915 https://www.eia.gov/todayinenergy/detail.php?id=42915 3. https://www.eia.gov/todayinenergy/detail.php?id=30672#:~:text=Broad%20ranges%20in%20winter%20temperatures,36%25%20who%20rely%20on%20electricity https://www.eia.gov/todayinenergy/detail.php?id=30672#:~:tex....
