UPDATE: Average wholesale electricity prices have plunged to $87/MWh in the September quarter, marking a dramatic 27% drop from the same period last year. This significant decline is driven by a remarkable surge in renewable energy production and the rapid expansion of battery storage, which is now displacing gas and hydro during critical evening peak times.
The latest Quarterly Energy Dynamics report from the Australian Energy Market Operator (AEMO) reveals that, despite record demand levels across major states like Victoria and New South Wales (NSW), renewable energy sources have transformed the market dynamics. The report highlights an unprecedented increase in renewable contributions, reaching a new record of 42.7% for the quarter, up from 39.3% last year.
The surge in renewable energy was complemented by a groundbreaking uptick in battery storage capacity, which skyrocketed by 150% to an average output of 215 MW. This has resulted in a substantial reduction in reliance on traditional thermal generation methods, with gas-fired generation decreasing by 11% and hydro output down by 3.5%. AEMO states that the increased presence of battery storage has led to a significant reduction in price volatility, benefitting consumers across the National Electricity Market (NEM).
On 22 September 2023, renewable energy contributions peaked at an astonishing 77.2% during a particularly sunny day, showcasing the potential of solar and wind energy in meeting demand. AEMO’s head of policy and corporate affairs, Violette Mouchaileh, emphasized the impact of electrification trends and the adoption of electric vehicles, stating, “The electricity demand growth was driven by colder weather, alongside broader trends of increasing electrification of homes, adoption of electric vehicles, and rising data centre consumption.”
State-specific insights reveal that Queensland experienced the lowest average wholesale price at $72/MWh, a 28% decline from previous year figures. Meanwhile, NSW saw a 31% drop to $90/MWh, and Victoria reported a 26% decrease to $77/MWh. South Australia, however, reported the highest average price at $104/MWh, affected by a single high-priced event earlier in July.
As AEMO continues to monitor these developments, industry experts will be watching closely to see how increasing renewable energy and battery storage capacity will reshape the Australian energy landscape moving forward.
