Evaluation of Solar Chimney Power Plant in Semi-Arid Region of Nigeria

Abstract

Solar chimney power plant (SCPP) is a renewable energy facility that converts the potential energy in the Sun into

kinetic energy and subsequently into electrical energy. The problem of global warming and electricity

generation/distribution in Nigeria cannot be over emphasized; however with the vast land in the semi arid region and

the potentials of the above technology, high prospects exist for solar chimney as it is a decentralized form of power

generation. The aim of this paper was to theoretically evaluate the performance of the solar chimney power plant in

semi-arid region of Nigeria, and estimate the amount of electrical energy that can possibly be generated. A

mathematical model was used to estimate the amount of power generated, and determine the relationship between

various meteorological and physical factors to the power produced. A solar chimney power plant with collector

diameter of 700 m and chimney height of 700 m can produce up to 3000 MW of electricity
