21 trucks. In Sacramento.
Routes vary 250 miles to 450 miles per day. I'll assume the average (350 miles per day)
1.7kWh per mile (note it's a heavy truck so it's one mile needs more than one kWh, not miles per kWh like an EV car).
That's 595kWh charging daily per truck (350 miles X 1.7kWh). Times 21 trucks = 12,495kWh per day.
And the article says it's solar powered, to which I call a giant BS. Are we really supposed to believe they have enough solar to generate 12 MWh daily? With Sacramento averaging 5.7 daily peak solar hours, that means they need a solar array of 2,100 kW just for an average day. Did they set up 700 solar panels? Do they have 12 MWh of battery storage to hold the solar power until the trucks come in for charging?
