Newly qualified Mechanical Engineer and previous student at the University of the Witwatersrand (WITS), Gabriel Wolfson, has produced an innovative research project titled “Developing More Effective Strategies for CSP Plant Operation Using Machine Learning.” This inspired work promises to enhance Concentrated Solar Power (CSP) plant performance, aligning with the global transition towards a low-carbon, sustainable energy future.
Gabriel’s project, undertaken in collaboration with Kathu Solar Park (KSP), a majority-owned subsidiary of ENGIE, uses historical operational data and advanced machine learning techniques to optimise the plant’s operational strategies. His artificial neural network and reinforcement learning algorithms identify optimal responses to seasonal and weather variations, enabling power production efficiency gains of up to 10–20% during critical periods between late autumn and early spring.
“I believe smart, data-driven solutions can significantly enhance the reliability and efficiency of renewable energy projects,” says Gabriel. “By leveraging machine learning, we empower operators to make more informed decisions, improving performance without replacing human expertise.”
KSP has been instrumental in supporting Gabriel’s work by providing access to operational data, site resources, and expert guidance. Dr. Gary de Klerk, Technical Manager at KSP, highlights the value of this research, “Gabriel’s tool provides a practical solution for a complex optimisation process. His achievement reflects Kathu Solar Park’s commitment to fostering young talent and advancing innovation in renewable energy. Tools like this ensure that more green power is delivered to the grid, strengthening our contribution to South Africa’s energy security.”
The research holds potential applications beyond CSP, extending to hybrid renewable projects that integrate energy storage and green hydrogen. As Gabriel joins the ENGIE Renewables Graduate Programme this year, he remains dedicated to contributing innovative solutions that improve efficiency, sustainability, and the broader impact of renewable energy technologies.
“Recognition of my work motivates me to keep exploring solutions that address real-world energy challenges,” Gabriel concludes. “My ultimate goal is to help drive the global shift to clean, reliable energy.”
KSP’s partnership with emerging talent like Gabriel underlines its commitment to innovation, research, and supporting a skilled workforce that can shape South Africa’s renewable energy future.
