Origin Energy has advised the Australian Stock Exchange that Eraring Power Station is running out of coal. The news resulted in the company slashing the profit target for the electricity business. It also threatens to deepen a worsening energy crisis engulfing Australia's east coast.
The company cited challenges, which it said had "deteriorated significantly" over recent weeks, in sourcing black coal for the 2880-megawatt generator.
Production issues at its primary supplier Centennial Coal's nearby Mandalong mine are not expected to ease until next year.
The company is seeking to source more expensive alternative supplies of the fossil fuel by rail.
