The global demand for electricity will soar over the next decade with an anticipated shortage of at least 600 GW expected by 2015.
Rupert Soames, group chief executive of energy rental company Aggreko, says "serious intervention" is needed now to meet this demand.
Soames was speaking yesterday at the launch of Aggreko's first service centre in the country - and the largest in Africa - in Midrand, Johannesburg.
The centre is one of 133 owned worldwide by the United Kingdom-based company widely renowned as the global leader in the rental of power generation and temperature control equipment.
The centre will provide temporary power for manufacturing, shipping, process industries, mining and construction industries, as well as for major sporting events.
"We are working on building a relationship with Eskom because it (Eskom) can definitely benefit from our equipment."
Aggreko has a long track record of providing power to sporting events worldwide.
In the last 12 months it has powered the Beijing Olympics and the European Football Championships.
In January the company also supplied power for the inauguration of US President Barack Obama in Washington DC.
