The Australian Energy Market Operator (AEMO), which operates and manages a variety of the country’s gas and electricity market functions, warns of a looming power crisis in parts of eastern Australia due to a potential gas supply shortage.

The warning marks a stark reversal of fortune for the country that not too long ago was buoyed by the promise of abundant natural gas and LNG exports.

The report warns of an insufficient supply to meet domestic consumption levels as soon as the summer of 2018-2019. The shortage is expected to hit hardest in South Australia, New South Wales and Victoria.
