State blackout puts SA power in spotlight

AAP

WHAT HAPPENED?


  • All of South Australia lost power last Wednesday during severe storms


  • Power was back in Adelaide in hours but took longer in some regional areas

WHAT CAUSED THE BLACKOUT?


  • An initial report from the Australian Energy Market Operator says the loss of three major 275 kV transmission lines and 315 MW of wind generated power in the storm increased demand on SA's main interconnector with Victoria


  • The extra demand overloaded the Heywood interconnector, which then shut down to protect itself from damage, cutting power to the state

HOW HAVE LEADERS RESPONDED?


  • Premier Jay Weatherill says AEMO's report confirms the blackout was a weather event, not a renewable event as suggested by Prime Minister Malcolm Turnbull and SA Liberal Leader Steven Marshall


  • The SA Liberals are calling for an independent inquiry into the blackout and say the state government's rush towards intermittent renewable energy played some role in the mess


  • Mr Turnbull says Mr Weatherill has a case to answer to "keep the lights on" in his state

WHAT'S NEXT?


  • AEMO will release a more detailed report on the incident and a set of recommendations, which could take up to six months to prepare


  • The nation's energy ministers are meeting in Melbourne on Friday, which Mr Weatherill says will be a chance to discuss the blackout and prevent more.
