If they are going to electrify at all, the only way it's going to work is diesel-electric hybrid. People have the impression that they can go to Home Depot and buy electrical supplies, amd find an empty space in their breaker panel and that would be enough to charge an electric class-8 truck.
In reality for even a small fleet you are going to need a 1,000 KVA pad mount transformer installed at your facility. If you wanted one next week, you need to get a time machine and go back to the year 2020 and start planning. The customer side of that transformer would be a 1,204 amp, 480 volt, three phase circuit. Just to put it in perspective, I've worked on emergency generators for the City of Philadelphia that were rated One Megawatt. They were powered by a 16v92 twin turbo 2 stroke Detroit. Roughly 1,500 horsepower. If you were in the enclosure doing tests and you had it under load you could feel your bones vibrating and after like 5 minutes your teeth started to itch.
Most places don't even have that much power coming down the street, you are talking about having to do upgrades all the way back to the substation. And lots of substations can't handle it and will need upgrades. Pepsi Sacramento's substation had to be upgraded to charge those Teslas. It took them 3 years to get the power.
I could go on and on with the problems. The six pulse rectification to turn the AC into DC creates 5th and 7th harmonics on the powerlines that doesn't end at the property line, it effects other power company customers. The people making these mandates and regulations are way way out of their league.
BTW here is what the American Trucking Association has to say about it
