Abstract
The supply and demand for electricity have outpaced available infrastructure in Nigeria despite the abundant energy resources. The paper investigates the determinants of electricity generating infrastructure in Nigeria for the period 1980 to 2016. Using an Autoregressive Distributed Lag model, electricity generation capacity was used as an indicator for electricity infrastructure development. Its expansion was based on the behaviour of inflation rate, total government expenditure, interest rate, private sector financial credit, exchange rate, real GDP per capita, real gross fixed capital formation, and the rate of urbanisation. Financial credit to private sector, total public expenditure, real per capita income, real gross fixed capital formation, urbanization, and exchange rate adversely affect the development of electricity generation capacity. Investment in generating assets is capital intensive, which should be matched with adequate private sector financing. If the power sector subsidy will remain and achieve its objective, strategies that will lead to sustaining exchange rate stability should be promoted. Based on estimate, every one million population require 1000MW of electricity to function in modern-day society implying that Nigeria needs 180,000MW of electricity capacity. The realisation of this is hinged on large scale electricity infrastructure investment enabled, partly, by the favourable macroeconomic environment.JEL Classification: E16, O1, O2
