Insights - January to March 2024

  • Electricity spot prices were higher than last quarter in all regions, despite an increase in low-priced offers. Weather was a key price-driver, with heat causing higher demand while a severe storm in Victoria caused network outages.
  • Heat and humidity drove record maximum electricity demand in Queensland.
  • Average forward electricity prices for 2025 fell in all regions, but Q1 2025 prices in Queensland and NSW.
  • Tallawarra B gas station and a battery commenced generating electricity this quarter. Further new capacity has been delayed to later this year.
  • Unusually, Queensland was a net importer with Victoria the only net exporter of electricity this quarter.
  • Decreased electricity baseload outages reduced demand for gas powered generation to record lows for Q1, offsetting reduced supply from Longford.
  • Domestic gas spot prices remain close to 2021 levels, averaging under $12 per GJ, driven by low demand over summer.
  • Strong short term trade on the gas supply hub and day ahead pipeline capacity auction with close to 90% below $12 per GJ.
  • Gas markets will remain vulnerable to shocks going into winter but high storage levels will mitigate these risks.
