RIO TINTO UNIT IN SOUTH AFRICA PLEADS FOR POWER TARIFF RELIEF
JOHANNESBURG — Richards Bay Minerals (RBM), a unit of mining giant Rio Tinto, warned that it will struggle to survive without a cut in industrial electricity tariffs. RBM – which mines titanium dioxide concentrate – said that despite deploying renewable power projects, its costs remain unsustainable under current Eskom pricing. The company told media it expects R250 billion in losses this year without relief.
RBM’s concerns center on its new Zulti South mine project in KwaZulu-Natal, a $1.2 billion greenfield expansion. CEO Mike Fraser said the government should extend the 35% special tariff enjoyed by big coal miners (via tariff pooling) to heavy power users like RBM, or risk the projects becoming unviable. Currently RBM pays the commercial tariff, which has nearly quadrupled in a decade. With electricity often cited as SA’s second-largest industrial cost after labor, RBM argues that high prices undercut foreign investment and miners’ competitiveness.
Why this matters to South Africa: Mining is 9% of SA GDP, so RBM’s plea highlights national energy policy challenges. If SA wants to attract mining and processing investment (a government goal), balanced tariffs are crucial. The story will also consider how RBM’s renewable energy initiatives fit into SA’s green transition and any precedent for tariff exceptions.
