Probably, I believe the main reason some businesses are not growing in some countries like Nigeria is lack of constant power supply. Imagine if a business uses the money they spend to power their generators to pump into their businesses. They will probably employ more people and therefore improving the economy.Most of those big generators you are talking about depend on diesel and not on petrol. And now diesel is quite expensive because here a litre of diesel is about 1.5 dollars compared to petrol which is about 0.4 cent.. most business organisation will have a lot of challenge when using this type of generator.
