Are you sure that the problem is centralization and not interconnectedness? I think if Argentina had just one generating plant they would have found it a lot easier to get things back up and running - no coordination problems - and if they had a few dozen independent grids then only a handful of them would have been affected (just one, or even none). The grid, as it exists today, is rather distributed - hundreds of generating plants in both US East and US West, and I imagine the situation is similar in South America.
