It hurts to watch someone make a large investment and be dependent on something he or she has no control over. You can see this fellow has indeed taken steps in planning and constructing a dream scenario,Kudos. Now as someone with an electrical background, I have to ask, what did he upgrade from? In the video he is showing an upgraded service in what seems to be 3/4 to 1 inch conduit which houses what looks to be number two to perhaps 4/0 which at most would be 200 Amps. From his description and plans for his bar, his newest service seems to be woefully undersized. No doubt the man knows his stuff, but just as first sight he may need a much bigger service.
As always, I do hope the island can get their act together when it comes to the grid. It just seems as though it's one step forward three steps back.
