The larger crisis in Australia’s energy sector has been ongoing since May.
- State of coal-powered plants–
- While Australia still depends on coal for two-thirds of its power generation, the country’s coal-fired power stations are ageing and are not in a stable condition. Many of these have also been marked for closure.
- Also, nearly 25 per cent of the eastern market’s 23 gigawatts of coal-fired capacity has been out of service over the past month, with as high as 30 per cent being unavailable at times.
- Soaring coal and gas prices
- Global supply chains have been hit by the ongoing Russia-Ukraine crisis and the sanctions on Russia.
- Due to untimely domestic shortages, many Australian power generators were forced to secure oil and gas on spot markets, sending production costs skyrocketing.
- Domestic gas prices spiked to such high levels that AEMO intervened to cap prices at A$40 per gigajoule (GJ).
- The soaring prices of raw materials like coal and gas also had a domino effect on electricity prices, which again led the AEMO to introduce the A$300 price cap
- Domestic coal output hit
- Instances of heavy flooding in NSW and Queensland in earlier 2022 affected the coal capacity in mines.
- Besides, owing to technical problems, output has been curbed at the two mines that has disrupted the overall supply.
- Early winter
- A cold snap owing to the early arrival of winter drove up gas demands for heating households, while gas also needed to be diverted to fire up gas-run power stations owing to the power crunch.
- Meanwhile, Liquified Natural Gas (LNG) exporters on the east coast had been selling as much gas as possible into the export market in absence of Russian supplies.
- The market operator did order the exporters to divert any uncontracted gas they had into the domestic market, but it wasn’t enough.
