I don't think your numbers are that off, and once you add in maintenance costs the EV's are likely to be extremely competitive with current engines. There are more than PR reasons that every major company put in Tesla Truck orders.
From what I've read, at peak production the US has about 40% more electrical capacity than consumption (assuming I've made the right conversions - as a side note the difference between kilowatts and kilowatt hours is confusing to me). The problem isn't so much producing the electricity, it's getting that electricity to where it's needs. In the macro sense, we're talking about high voltage transmission lines, which at least in WI are very popular, providing they don't run anywhere near where you live. In which case they're the devil. In the micro sense - getting the charging stations installed and maintained is going to be a right mess.
Don't plan on hauling anything heavy in 25 years.

not4hire and gentleroger Thank this.

Large horsepower is really only used to accelerate. Once you get up to cruising speed you are only using the power needed to overcome wind resistance, rolling resistance, and driveline losses, and to climb a hill. Bonus, an electric motor setup to regeneratively brake will capture alot of the energy used to go up a hill when you go back down.not4hire Thanks this. -

One of the concepts for electric cars (and trucks) is that they are tied to the electric grid when not in use and become storage capacity once the vehicle gets above a threshold of charge. So "the grid" could draw down the pack to say 80% charge to cover a high usage time then recharge the pack after the power plants come up to supply the drain on the grid.
Probably not a good assumption for OTR type trucks, However all those snowed in fleet trucks and buses sitting at a terminal and plugged in would be electric capacity available to offset the generating stations that dropped off (like during this cold snap) potentially heading off the rolling blackouts.
Currently chargers for cars can be set up to only charge during nonpeak hours for the folks that have electric meters that are set up to give consumers a lower cost of electricity during off peak hours.not4hire Thanks this. -

Also of note is how marginal the supply for current demand is, Utilities are having a challenge meeting the demand from when people get home from work and start turning on all their home appliances. If you were to remove EVs from the picture and the plan, the status quo is not adequate for normal population growth and the growing per-capita consumption.
