How to bid for an Eskom tender


Eskom is a government-owned public utility company that is responsible for providing about 95% of the total electricity supply to South Africans at large. Established in 1923, it is among the top seven utilities in the world in terms of generation capacity and among the top nine in terms of sales. The organisation has a number of important and extensive services to provide to the African continent which requires a large amount of skill.

As an operator of numerous power stations throughout the country, including Africa’s only nuclear power plant at Koeberg in the Cape, Eskom often requires assistance in the form of supply and delivery of electrical components, coal plant maintenance, etc.

Sourcing this assistance is done through a tender process. Essentially, a tender is an offer to do work or to supply goods at a fixed price. The process is designed to ensure that the work to be done is given out in a fair way. Driven by a number of procurement policies, tenders become binding business contracts once accepted by both parties.

Eskom awards tenders due to the need to outsource skills or services provided by some private companies. The tenders may be small-scale or relatively huge projects. An example is the latter, is the tender offered to French firm Areva. Dubbed by the media as “the never-ending tender,” because it took four years to finalize, this tender is for the refurbishment of the Koeberg nuclear plant.
