MELBOURNE, Aug 5 (Reuters) – Global miner Rio Tinto (RIO.AX) has received several offers to build 4 gigawatts (GW) of wind and solar farms to power its alumina and aluminium operations in Australia’s Queensland state, the company’s Australia head said on Friday.
Rio Tinto Chief Executive Officer Australia Kellie Parker said the company, the country’s biggest single power user, had received proposals for “a lot more than the 4 GW” that it asked for in its call for proposals key to slashing its carbon emissions.
Rio Tinto said in June its Boyne aluminium smelter, Yarwun alumina refinery and Queensland Alumina refinery need a combined 1,140 megawatts (MW) of reliable power, and was seeking offers to build at least 4,000 MW, or 4 GW, of wind and solar power backed up by energy storage which would be required to supply steady power. read more
