That's a common one heard for Guam.
If you are truly interested, do some research in stuff like "shore power" (both breakers and grounding) and "ship power" requirements vs a commercial power plant.
Disclaimer: I'm not an electrical engineer nor Naval nuclear engineer. But I did spend the past week around many of both. . . almost as good as staying in a Holiday Inn for the week. 
You don't like my comments, but I am an Electronics and Software engineer.
The amount of power in Joules in the grid is hard to grasp.
But all this stuff has to be synchronized or things explode.
Power plants are designed to shut down if the least little thing goes wrong.
I was helping on an engine run on a C5A once and the engine guy paralleled the
Ground Power Uni(GPU)t with the engines. Whole airplane shook and the GPU flipped over and
made a mess. The GPU was half the size of one of your Honolulu buses.
I don't think wind power is reliable. I have 10.6 kW of solar panels ready to be installed,
so I'm amenable to PC power. It is overpriced and not logical.
I'm a geothermal believer guy and local politics kills that. Tahitians that showed up
here in Hawaii 800 years ago are so "special", they can dominate
and override logic.
So pay UP!
