.  The blackout also sparked a war of words between supporters of renewable power and those who blamed SA's high reliance on wind and solar generation as a contributing factor.  That included an infamous confrontation between former Premier Jay Weatherill and then Federal Energy Minister Josh Frydenberg at a media conference in Adelaide, with Mr Weatherill lashing the coalition's "anti-South Australian stance" as a disgrace.  Current Energy Minister Angus Taylor said it was important for the regulator to enforce market rules.  "We need to have reliable power in this country ... and that means all generators need to perform," he said.  In its action, the AER alleges each of the wind farm operators failed to ensure that their plant and associated facilities complied with their generator performance standard requirement to ride-through certain disturbances.  It also alleges that the wind farm operators failed to provide automatic protection systems to enable them to ride-through voltage disturbances to ensure continuity of supply, in contravention of the National Electricity Rules.  The AER is seeking declarations, penalties, compliance program orders and costs.
