Thanks, just need to understand the terms you laid down like

"power suppliers are regionalised"

From a meeting I attended a while ago, over in the island of Hispanola or specifically Dominican Republic, their government have struck a deal with Venezuela for oil through CHavez trade policies. They give oil in exchange to have preference in trade negotiation and support of Venezuela products.

Dominican Republic may be making money but at the end of the day it goes to another coffer.

Just want to know if certain carribean islands have a particular network different from another island.

For instance since Dominican Republic is Spanish speaking Venezuela certainly have an advantage in that negotiation. On the same island with Haiti, it is not benefiting. So any money Dominican make would be being that 'middle man' on the island come from Haitian trade development.

This is what I am attempting to aim for.

Thanks otherwise.
