Up to 1.3 million households in Victoria are at risk of blackouts during heatwaves this coming summer if no extra power generation is secured and two power plant outages last longer than expected, the Australian Energy Market Operator has found.
Failures at AGL Energy's Loy Yang coal power plant and at an Origin Energy gas plant in Victoria pose a "significant risk" of blackouts of up to four hours if repairs last longer than their scheduled date in December into the summer, AEMO said in a report on Thursday.
