Power delivery could be an issue. I guess it depends on how many ships a day you're serving. If there's just one or two a day, your infrastructure needs to handle short bursts at high capacity but then sits idle 90+ % of the time. If you're serving a hundred ships a day, it sort of just averages out and you can be at close to maximum capacity most of the time. I'd imagine most power utilities would love to have customers that consistent. Delivering power to the ships would be interesting. I suppose it would have to come in at high voltage (either AC or DC) and be stepped down to a suitable pack voltage. That means each ship would have the equivalent of an electrical substation on board.
