One possible reason ( and return on investment) for the new cable is "Cruise Ship Shore Power"4th cruise ship pier?
It's currently being done in Florida and especially in Miami's port. It cost them $25 million per terminal pier to install it and then they charge the docking ship for energy use. This allows the cruise ship (a floating small city, bigger than any hotel the island could build) to shut down it's generators while docked for 8-12+ hours. The cost is comparable to their fuel burn but the benefit is a big reduction of those engine hours (wear & tear) as well as down time to do generator maintenance. They promote it's reduced emissions but in reality it's a huge cruise ship savings in down time and equipment life span. Since 6-12 cruise ships are already using the dockage, that's an immediate customer, unlike the 2+ years it would take for a hotel to be built. When the ships leave at night, that un-used capacity is available to the island homes overnite when demand rises.
