MELBOURNE (Reuters) – 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 destabilized the national grid and soaring natural gas prices have driven up power tariffs.

A blackout last year forced Olympic Dam to shut for two weeks, costing the company $105 million. Over the past year, rising power bills have added around $30 million to its costs.  Olympic Dam President Jacqui McGill said security of supply, price and system reliability are all challenges for the mine.

“Cheaper power – that’s the key for me,” she said at an American Chamber of Commerce event in the South Australian capital of Adelaide. Power prices need to drop 25 percent to make Olympic Dam copper more competitive globally, she said.

While the state of South Australia has taken steps, such as lining up 129 megawatt hours of battery capacity from Tesla Inc, to help avert power outages from next summer, more needs to be done, McGill said.
