With a generating capacity of more than 40,000 MW, South Africa-based Eskom is Africa’s largest energy utility, and ranks as one of the top five energy utilities in the world. Eskom is a de facto monopoly in South Africa, and also generates over half the electricity produced in the whole of Africa, with operations in 31 countries on the continent. Because of its heavy reliance on coal, it is the primary source of greenhouse gas emissions in South Africa. Eskom management has also stated that it intends to rely increasingly on nuclear power. And in recent years, Eskom has begun to promote new dams and buy existing hydropower plants around the continent as it seeks to expand its influence across Africa. This paper explores the company's social and ecological footprint across Africa.
