Analysis of the Wind Energy Supply and Integration in South Africa

Abstract

South Africa’s energy network is under severe pressure due to low supply and overwhelming demand. With an increase in renewable energy providers, specifically wind energy, it offers great apprehension to know how the supply can aid electricity demand. This research aims to create insight into the wind energy supply of South Africa and question how well this supply meets the demand of South Africa. The methodology used in this work highlights the importance of access to public datasets to dispel misconceptions in the energy industry. Additionally, the work supports network planning and the arguments for increasing wind energy penetration on the South African grid. Wind profiles and typical energy production of South African wind farms are compared to electricity demand. The geographical spacing of the operational wind farms are considered. It is observed that wind energy supply assists in the peak electricity hourly demand as well as seasonal peaks.
