A protracted strike in the coal sector threatens South Africa’s electricity supply, say consultants Frost & Sullivan.

Ninety per cent of South Africa’s electricity is generated from coal, and dwindling stocks are likely to mean Eskom cannot guarantee the availability of electricity, said Wonder Nyanjowa, mining industry analyst at Frost & Sullivan.

But Eskom claims all coal fired power stations in South Africa have stockpiles, which can fuel their plants for an average of 38 days.

South Africa consumes two-thirds of its coal production in energy generation and in manufacturing synthetic fuel. The rest is exported, mainly to the EU, China and India.

Eskom’s construction programme is likely to increase coal consumption by an additional 50 million tonnes between 2015 and 2017.
