What? Peak electrical consumption is during the day. The big challenge for electric companies is the swing between the night trough in demand and the day peak. Night charging is excellent because it flattens that curve. Bringing demand into a straighter line and allowing electric companies to generate at a steady rate without having to cycle production up and down. I glanced though the article and found no mention of that. You can’t write a piece like this and begin anywhere else. This article gets an F- for effective communication and persuasion.

The article (and paper) is saying that in solar-dominated generation regions, peak electrical production is during the day when the sun is out, and the trend seems like it's not stopping. I haven't actually read the full paper, but to quote the abstract: > We study charging control and infrastructure build-out as critical factors shaping charging load and evaluate grid impact under rapid electric vehicle adoption with a detailed economic dispatch model of 2035 generation. We find that peak net electricity demand increases by up to 25% with forecast adoption and by 50% in a stress test with full electrification. The paper is at https://www.nature.com/articles/s41560-022-01105-7 https://www.nature.com/articles/s41560-022-01105-7, I only briefly skimmed through it but it seems plausible. The assumption that a flat electrical load is desirable is less and less true as renewables go on the grid; of course, if we just took the (imo sensible) step to go all-nuclear, hydro, and geothermal for baseline load, then diurnal electrical consumption would not be desirable, but with the solar that might not be the case.

I have TOU based electric plan in CA, and the summer times are about to shift to peak starting at 4pm (from 10am). This huge shift is because of excess capacity from installed solar. 4pm is early enough that there's lots of use, but late enough that solar is tapering off.
