South Africa is home to a glut of energy companies ranging from renewable energy specialists to gold miners with a global presence.

The country’s energy demand stands at more than 200 billion kilowatt hours (kWh), making for a per capita rate of more than 3,600 kWh.

The methods catering to this demand have changed drastically over the years, with coal slowly being phased out as wind and solar increase in prominence.

It still relies heavily on fossil fuels, however, with a recent report by Stats SA revealing an 85.7% reliance on the power generation method as recently as 2016, followed by nuclear power (5.2%) and natural gas (3.2%).

Here we take a closer look at some of the companies operating right at the top of South Africa’s energy sector.


Top energy companies in South Africa


Formed in 1923, Eskom owns the majority of power stations in South Africa and accounts for 95% of the country’s electricity and 45% of the electricity produced across all of Africa.

The state-owned utility generates, transmits and distributes electricity to industrial, mining, commercial, agricultural and residential customers and redistributors.

It has been in a precarious financial situation for some time now, with the South Africa government having to pay 5bn rand (£270m) to help the company cope with declining revenues and rising costs.

The country’s Public Enterprises minister Pravin Gordhan said on Johannesburg-based Talk Radio 702: ““We have had an extreme financial difficulty as a result of state capture – the damage that has been caused has been huge.”

“However, Eskom isn’t on the brink of financial collapse – the problem is well under control.”



Sasol’s history dates back to midway through the 20th century and it remains to this day one of South Africa’s largest chemicals and energy companies.

The firm has more than 30,000 employees working in 30 countries around the globe, and is listed on both the Johannesburg and New York stock exchanges.

As of 2014, Sasol comprises two upstream business units, three regional operating hubs and four customer-facing strategic business divisions.

Its various products include liquid fuels, low-carbon electricity and a plethora of chemicals.

Like many energy companies in South Africa, it too has felt the strain caused by Eskom’s woes, and reported a 6% decline in its core earnings per share for the year ending June 2018, citing power outages from the state-owned supplier as being at fault.



Based in Pretoria West, Exxaro specialises in coal mining and heavy mineral extraction, and was formerly known as Kumba Resources Limited before it changed its name in late-2006.

Its wide-ranging assets include coal operations and investments in iron ore, pigment manufacturing, renewable energy (wind) and residual base metals in countries around Europe and the US as well as South Africa.
