Market Commentary

In June 2024, electricity spot prices climbed in all states across the National Energy Market excluding New South Wales as low renewable output and unplanned generator outages bite. 

For the fourth consecutive month, low wind, solar and hydro output have caused prices to spike across the states of Queensland, South Australia and Victoria.  

The only state to experience a drop in prices was New South Wales, but this was only because the previous month was a rollercoaster for the state where unplanned outages and abysmal renewable output caused prices to go through the roof in May. 

The month-on-month increase in spot prices did not translate into the wholesale futures market, where prices dropped in all states except South Australia. SA relies heavily on gas generation, battery discharge, and interconnector imports when renewable energy is low, giving the state quite distinctive characteristics to the rest of the NEM. 


End of Financial Year Spot Prices Comparison 

As we close the end of the financial year for 2023-2024, it is worth noting that electricity spot pricing in all states making up the National Energy Market registered significantly cheaper prices on the spot market than in the previous financial year. 

Prices dropped in all states:  

EOFY End New South Wales Queensland South Australia Victoria
2023$145/MWh$145/MWh$123/MWh$100/MWh
2024$102/MWh$88/MWh$79/MWh$63/MWh

End of Financial Year Wholesale Futures Prices Comparison 

Wholesale futures prices did not follow the same trajectory as the spot pricing market as prices across the NEM increased from the end of the last financial year to this one. 

EOFY End New South Wales Queensland South Australia Victoria
2023$124/MWh$96/MWh$112/MWh$77/MWh
2024$134/MWh$114/MWh$116/MWh$83/MWh

Supply-Demand Tightness in Q2 

Throughout the second quarter (Q2), the electricity market experienced supply-demand tightness due to prolonged wind lulls, increased heating demand from cold temperatures, low hydro production, a rise in coal production, and unplanned outages at various generators throughout the NEM. 

East Coast Gas System Notice 

Supply issues are further compounded by potential gas shortages. AEMO issued an ‘East Coast Gas System Risk or Threat Notice’ on June 19, forecasting ongoing supply challenges until September 30. 

High gas-powered generation demand and production constraints have depleted storage inventories, impacting gas supply adequacy. 


Generator Outages Impacted demand and supply 

Increased demand and low renewables supply put a squeeze on prices in June and these were further affected by outages at several generators across the NEM. 

These outages collectively strained supply conditions in affected regions, contributing to increased spot prices and highlighting challenges in maintaining grid stability during periods of heightened demand.  

CS Energy also announced that the staged return of Callide C4, which was originally slated for the beginning of June, has been pushed back. It was due to return to full capacity by 31 July, but it looks like a partial return may be around that date with all return pushed into August. 

  1. Eraring Unit 1 (NSW):
    • Outage Start: Offline since June 8th, 2024, due to ID Fan limitations. 
    • Return: June 10th, 2024. 
  2. Eraring Unit 2 (NSW): 
    • Upcoming Outage: Scheduled for unplanned maintenance in the second week of June. 
    • Decision: Initiated on June 7th, 2024. 
  3. Yallourn Unit 3 (Victoria): 
    • Outage Start: Offline since June 7th, 2024, due to an Economiser Tube Leak. 
    • Repair Status: Under maintenance with expected return pending repairs. 
  4. Kogan Creek (Queensland): 
    • Outage: Experienced outage on the morning of June 20th, 2024. 
    • Return to Service: Returned to service on the evening of June 21st, 2024. 
  5. Tarong Unit 3 (Queensland): 
    • Outage: Came offline late afternoon on June 21st, 2024, due to unplanned reasons. 
    • Current Status: No immediate timeline for return, under observation for further updates. 
  6. Mt Piper Unit 1 (NSW0: 
    • Outage: Offline due to boiler tube leak since June 18th, 2024. 
    • Expected Return: Scheduled to be back online by June 24th, 2024, with repairs ongoing. 

Low renewable output causes spot price upticks 

For the fourth consecutive month, lower than usual renewable energy generation plagued the National Energy Market, contributing to higher spot prices. 

Demand and Supply Dynamics 

The chilly winter temperatures in major cities such as Brisbane, Sydney, Melbourne, Adelaide, and Hobart have significantly escalated heating demand, leading to increased overall energy consumption.  

Additionally, low wind yields and reduced hydro production in South Australia, Victoria, and Tasmania further strained the available generation capacity, affecting market conditions. 

Wind Lulls 

  • Wind Lull #1 (April 13th to April 20th): Notable underperformance in Victoria (VIC), New South Wales (NSW), and parts of South Australia (SA). 
  • Wind Lull #2 (May 13th to May 18th): Significant underperformance in South Australia (SA) and Victoria (VIC). 
  • Wind Lull #3 (May 22nd to May 28th): Widespread underperformance in Victoria (VIC), South Australia (SA), New South Wales (NSW), and parts of Tasmania (TAS). 
  • Wind Lull #4 (June 5th to June 11th): Marked underperformance in Queensland (QLD), South Australia (SA), and Tasmania (TAS). 

Lower Hydro Output impacted prices further 

Hydro production in Q2 2024 was one of the lowest compared to the past 10 years, potentially ending as the second lowest. 

Historical comparisons indicate 2008 Q2 had the lowest production, followed by 2007 Q2, closely matched with 2012 Q2 and 2024 Q2. 

Higher prices during midday in Q2 2024 might have reduced time-shifting opportunities for pumped hydro plants like Wivenhoe, Shoalhaven, and Tumut. 


AEMO stresses that renewables, batteries, and gas are the lowest-cost electricity sources as coal retires 

In its 2024 Integrated System Plan, The Australian Energy Market Operator has again confirmed that renewables, batteries, and gas are the lowest-cost electricity sources as coal retires. 

As coal-fired generation retires, renewable energy, supported by transmission, storage, and gas-powered generation, is identified as the lowest-cost method for electricity supply. 

This approach supports Australia’s transition to a net-zero economy

  • Optimal Development Path (ODP)
    The ODP is the lowest-cost pathway to meet energy policies on emissions reductions, with an annualised capital cost of $122 billion by 2050. 
  • Transmission Projects
    Seven new transmission projects have reached ‘actionable’ status since the 2022 ISP (Integrated System Plan). 
    Investment in these projects will reduce costs for consumers, recoup $16 billion in investment, save an additional $18.5 billion in avoided costs, and deliver $3.3 billion in emissions reductions. 
  • Government and Industry Support
    The ISP aids governments and industry in planning and investing in necessary infrastructure for the energy transition. 
    It ensures reliable, affordable electricity by adapting to economic, technical, and policy changes. 
  • Exclusion of Nuclear Power
    The ISP does not include nuclear power, as it is not permitted under current Australian laws. 

Coalition touts nuclear as the solution to the country’s electricity problems 

The Federal Coalition has made a pledge to invest in nuclear power generation if elected to government at the next general election. 

It has proposed seven sites for potential nuclear power plants, sparking extensive debate on energy policy and environmental considerations.
