Im brazillian, and the energy cost and availability in a industral environment its low, unless you produce your own. The costs of solar arrays its so far expensive too, the import fees its 60%.

Actually I have a small farm on Paraguay, the energy cost could go as low as $0,039 but you have some limitations like 3mw per site, if you want some bigger farms you have to make a substation, then you gonna need some very political influence$$$. The import fees its very low.

Argentina as i heard have low cost when Cristina Kirchner was president, today the energy dont have more the subsidy, dont know the cost right now.

Venezuela... forget about it.
