Feasibility Analysis of Reconfiguring Conventional Underground Water to Solar Powered Pumping Systems in Nigeria
Mechanical Engineer with over 9 years experience in Water and Renewable Energy Engineering projects
Advice for future students
"Take the programme seriously despite challenges of combining work with studies as this is what it takes to have full understanding of how things work in the renewable energy sector".
Experience with the MBA Renewables
"I like the blended approach used in the programme between Renac and Beuth. This has helped to bridge the gap between practical and theoretical knowledge".
Abstract of the thesis:
This thesis describes the Feasibility Analysis of Reconfiguring Conventional Underground Water to Solar Powered Pumping Systems in Nigeria. It also examines selected problems associated with water and power supply in Nigeria, performance of various underground water projects across the country, Solar energy resources in Nigeria as well as the possibilities of replacing the conventional water pumping systems with solar powered from both technical and economic points of view.
The economic analysis was done using the Life Cycle Cost Approach which is the total cost of all system components over its lifetime typically between 10 to 15 years. The most significant parameters of the life cycle costs put into consideration are initial costs, energy costs, and maintenance costs.
Economic Analysis was equally done to determine the Net Present Value (NPV), Internal Rate of Return (IRR) and Cost Benefit ratio while running the system with diesel, grid and solar PV separately as power source.
The results revealed that running the system with solar PV gives a quicker return on investment with a Net Present Value (NPV) of 6,468.02 Euro and an Internal Rate of Return (IRR) of 22% as well as a Cost Benefit Ratio of one at the seventh year. It was also justified that running same on either diesel or national grid is neither profitable nor sustainable as the status of the power supply from the national grid is epileptic and unreliable with an average power production of 2,500MW against the projected power requirement of 12GW for a population around 182 million.
