When the government of President Olusegun Obasanjo came into power, there was a very serious determination of that government to tackle the power. The then government discovered that the problem was capacity limitation.
The quantum of power that a nation has, determines its growth potentials. So when a nation doesn't have power, you can also imagine what that does to its economic development. And there is a multiplier effect of power. So if you have ten times more power, what you do to the economy is that you add ten to fifteen more times more to the development of the economy. Hence the birth of the National Integrated Power Project (NIPP).
The National Integrated Power Project (NIPP) means that you must have all the ingredients that make up power into one single entity (Value chain).
And that is whether it is fuel, gas, water or biomass, the power turbines themselves, the transmission, infrastructure, the distribution infrastructure, all together into one ambit, hence the word integrated. Now national because power business is highly capital intensive, hence the project is being funded by the three tiers of government for the benefit of all Nigerians.
When you have a system where the governance infrastructure is tailored to have such perception in terms of integration. You have smoothes delivery of your services by every sector of the economy.
This is where the NIPP and PHCN are related, because the PHCN also deals with gas, water as the case may be and power generation, transmission and distribution.
The government also invited the private sector to come into power. You see Agip in Obiafuru-Obirikom ob-obi, you find shell in Afam in Rivers State, you find AES in Egbin. They gave license to so many private companies.
