Planning for Large-Scale Wind and Solar Power in South Africa

Identifying Cost-Effective Deployment Strategies Through Spatiotemporal Modelling

South Africa hopes to expand wind and solar power. Success depends on how and where to deploy the technologies. This study develops a 10-year database of expected power generation for these technologies across South Africa. A power system model simulates the performance of different spatial deployment strategies in 2040. The results suggest that optimization of the location and quantities of the technologies could significantly reduce the cost of greenhouse gas abatement compared to conventional approaches. The data and techniques utilize open-source satellite data and software to minimize the cost of analysis, an approach that could be translated to other contexts.
