During the 2014 heatwave, Victoria and South Australia both experienced near-record demands on the NEM power system. The level of demand experienced has not been seen since the last heatwave in 2009 where record operational demands were set
The NEM power system proved capable during this high demand period, with demand able to be supplied at all times. While minimum reserve levels were at times low, AEMO did not require any load shedding. Small distribution level local outages were experienced due to distribution equipment failures.
AEMO has gathered data from the 2009 and 2014 heatwave events (detailed in the summary of operational and market data).This paper is a summary of the events and presents interpretations and observations of this data.
