Exxaro Namakwa Sands 13.7MW CO / H2 Generation Plant, South Africa

PEC provided concept designs to determine the suitability of technologies for waste heat to power generation at Exxaro’s Namakwa Sands smelting plant near Saldanha in the Western Cape. The studies looked at the use of off-gases from the smelting process – carbon monoxide (CO) and hydrogen (H2) – as sources of combustion to generate electricity to power the smelter and to potentially feed the local transmission grid. PEC also investigated the impact of the new generating plant on the existing plant’s electrical distribution network.

Thereafter, PEC provided final design and construction documents for the 13.7MW off-gas generating plant The plant interconnects to the 33kV smelter plant consumer substation and offsets power taken from the national grid.
