April 2021 Energy Market Review

Share now:         Copied!

Throughout April 2021, the energy transition continued to send shockwaves through the energy industry – even as low wholesale prices showed signs of reversing. This month saw three sudden departures of high-profile energy CEOs. AGL’s Brett Redman jumped ship just weeks after announcing AGL’s split while Stanwell’s Richard Van Breda was pushed out after suggesting the mothballing of two coal-fired power plants due to the influx of cheap renewables. Energy Australia boss Catherine Tanna will also step aside. Meanwhile, wholesale prices are on the way up, having recovered from the January dip, and are now largely trading at December levels.

South Australia

SA April 2021 energy market prices
  • South Australia’s 2022 and 2024 contracts rose 10% and 11% respectively.

  • SA followed Victoria as the second-largest contributor to the record wind output on April 13 contributing 1,273MW which equated to 84% of its own demand at the time.
  • AEMO’s recently released Quarterly Dynamics Report found that renewables reduced SA’s average quarterly price down $10/MWh and resulted in a negative average price during the day – a first for any NEM jurisdiction.

April 2021 marked the first consistent period of widespread energy price rises since 2019. Renewable output records continued to tumble and the shakeup among Australia’s energy leadership gained steam. A disorderly exit of incumbent generators threatens increased price volatility and decreased energy security. We can help your business lock in price certainty to ride out the bumpy road ahead.
