The latest monitoring report on renewable energy power plants from the National Energy Regulator of South Africa NERSA indicates that, while installed renewable capacity continues to expand, actual energy output remains variable and dependent on resource conditions.
The March 2026 report tracks the performance of wind, solar photovoltaic PV and concentrated solar power CSP plants connected to the grid under the Renewable Energy Independent Power Producer Procurement Programme.
The data shows that renewable generation continues to contribute to the national energy mix but output fluctuates across technologies, reflecting the inherent variability of wind and solar resources. Plant performance, measured through indicators such as energy sent out, availability and capacity factors, differs significantly depending on technology and operating conditions.
