BHP Billiton raises 'power security' fears after latest South Australia blackout

CEO Andrew Mackenzie warns jobs in peril due to government policy failure after power was cut to 200,000 properties on Wednesday night

Federal and state governments must make power security a priority after South Australia suffered another widespread blackout, the boss of mining company BHP Billiton has warned.

Andrew Mackenzie said problems which cut power to 200,000 properties on Wednesday night showed that investment and jobs were being placed in peril by the failure of policy to both reduce emissions and secure affordable and uninterrupted power.
