Recently, CLIMsystems Ltd. analyzed future climate impacts on the Hazelwood brown-coal fired power station located 150 km east of Melbourne in the Latrobe Valley, Victoria, Australia. These impacts included changes in ambient temperatures. The power station produces around 10 terawatt (TW) hours of energy, supplying up to 25% of Victoria’s energy requirements and 5.4% of Australia’s energy demand. The power station is a heat-intensive operation and relies on water extracted from a dedicated cooling pond. The Australian Energy Market Operator has forecast that Victorians would use an average about 10,250 megawatts (MW) of electricity per day through the three days of the recent heat wave event. On a typical summer day Victorians use about 6600 MW a day. Blackouts have occurred in parts of Victoria, and fan numbers were down during the opening rounds at the Australian Open grand slam tennis event with some players expressing concern after heat exhaustion. Tournament officials finally enacted their “Extreme Heat Policy” (for temperatures exceeding 42°C or 108°F) and suspeneded matches on the outer courts for several hours. Over this stretch of several days in January Melbourne experienced its longest heat wave in more than a century.
