South Africa will launch the tender for the approximated $72b expansion of its nuclear power plants in June when state utility Eskom requests proposals from companies bidding for the project, Reuters reported.

According to FORTUNE, South Africa, which is the only African country holding a nuclear power station, wants nuclear power to be the main source for power generation expansion. Accordingly, the country has asked Eskom to procure an additional 9,600m of capacity to reduce the country’s reliance on an aging fleet of coal-fired plants.

According to an internal Eskom document, the country’s nuclear program will begin. Eskom’s document states that the firm will issue requests for proposals in June and will set the deadline for bids in September, and for evaluation in December.

The final decision on the winning bidder will be in March 2018 and the contract will be signed between December 2018 and March 2019.

Eskom’s spokesperson, Khulu Phasiwe stated, “Nothing at this stage has been decided on, those dates were suggestive dates. If everything goes well, we will issue a request for proposals around June. The National Treasury, Department of Energy and the Department of Public Enterprises still have to make their own findings.”
