“Suddenly the peak grid drain time will start around 6 pm local time. As soon as people get home from work they will start charging their cars. Nearly every car in the area will be getting charged at the same time.
You drive home, plug in your car, then go into the house.”
Take a large Texas city say Houston. Everybody gets in at 5:30-6PM, and plugs in EV. Maybe you have supper but for many it’s get back on the road for baseball, football, band practice etc. in 45-60 minutes. These trips are not always to the local ball park 2 miles away could easily be 20 miles for an away game. Going to be doing some fast food and maybe some shopping with the trip so maybe 50 miles total round trip would not be uncommon. So at about 8-9PM you have another surge in demand for power. You add in a August 100 degree day in Houston with 90% humidity till 11PM or so I don’t see how the existing grid handles that
” So at about 8-9PM you have another surge in demand for power. “
Markets adjust with lower rates 9PM to 9AM. No surge.
