Dr Grové Steyn

BIng(Ind), BA, MSc, DPhil

One of South Africa’s leading infrastructure and regulatory economists, Grové combines high-level strategic insight with strong economic and financial analytical skills.  He takes a keen interest in the economic and institutional complexities of developing infrastructure and appreciates the challenge of aligning the stakeholder perspectives of investors, financiers, service users, policy makers and regulators in order to facilitate development in the infrastructure industries.  His engineering and utility background provides him with a good understanding of the related technologies, and he maintains an interest in the economics of technology.

Most recently, Grové was appointed to the President Ramaphosa’s Economic Advisory Committee (PEAC). Before this he served on the Eskom Sustainability Task Team.

Jesse Burton

BA (Hons, History), MSc (Energy Studies)

Jesse is a reseacher in the Energy Systems, Economics, and Policy group at the Energy Research Centre at the University of Cape Town. She holds an MSc in Energy Studies from UCT and her Masters thesis examined the role of industrial policy in meeting climate change mitigation objectives in South Africa. Since then her research has focused on the South African coal and electricity sectors.  Some of her recent research as examined the political economy of decarbonisation, the politics of fossil fuel subsidies, the greenhouse gas implications of future coal investments, and the costs and risks of stranded assets in the South African energy sector. She is currently involved in research examining the political economy of the South African coal sector, fossil fuel finance,  and developing transition pathways for South Africa’s coal sector in the context of climate change.
