Nigeria spent over 25 billion naira in 2012 importing power generating sets

The group good governance lnitiative,GGI reports that the government spent 25 billion naira on importing generator sets to supplement the insufficient power supply in the country.
The country barely is able to supply a tiny 4,000mw for the over 160 million people, while south africa with 50 million people generate 40,000mw
The deplorable state of power supply in the country is really affecting the country's businesses. It was reported that in 2012 the individual businesses including banks, and small scale business spent a total sum of over 2 billion naira. It was also reported that 60 million people who use generator sets spent over 1.56 billion naira. This has made so many business to colapse and even the ones remaining to lose a lot of money to power generation
