BHP Billiton is looking for ways to shore up power supply and bring down power costs at its Olympic Dam copper mine in Australia, as it plans to expand following a string of electrical outages, the mine’s head said on Friday.
The mine has been badly hit by an energy crisis in Australia stoked by the rapid rise of wind power and closure of coal-fired power plants. This has destabilised the national grid and soaring natural gas prices have driven up power tariffs.
