1.0     INTRODUCTION

          The primary aim of National Electrical Power Authority (NEPA) is in cardinal point which is to generate, transmission, distribution and sales electricity within and outside country.

National Electric Power Authority NEPA can be regarded as heart beat of the nation economy as the operation of machines use in industries and most household equipment depend on electricity.

Today National Electric Power Authority (NEPA) meets total maximum energy demand from the total installed capacity of the Authority power station which is 600mw, the terminal power station are strategically located at Egbin, Ijora, Delta Ugheli, Sapele and Afan, while the hydro power station generate are located at Kanji, Jebba and Shoro, the terminal power station generate electricity for exportation into grid system.

As part of the positive effort of NEPA to ensure the electricity generated reach the appropriate quarters in the next millennium, it has put in place 11,000km of transmission line running across the nation.

Many researchers had previous carried out research work on NEPA, on some aspect of electricity consumption with related objective. Individual article and study of NEPA, they have put forward many analysis and suggestion basically on consumption, supply and distribution of electricity.

According to Chief A.O. Osho of Abule Egba Community in Lagos State, put up a protest on behalf of the community in the daily times of “21st of March 1991” WHY DO WE HAVE INCENSANT POWER FAILURE, Mr. Muyiwa Otunowo (P.R.O) Nepa Lagos South directorable through a booklet title “planning ahead of NEPA” answered the question he said NEPA plans ahead a very much so to meet adequate constant and supply of electricity, the future demand must be known since we can not produce and store electricity. The national electricity as can be done to most of consumer goods or water.
