Record-Breaking Surge in Australia's Renewable Energy Capacity Alleviates Blackout Threat

Australia's commitment to transitioning to renewable energy sources has led to a significant reduction in the threat of blackouts as coal-fired power stations are shut down. The Australian Energy Market Operator (AEMO) has published its 2025 Electricity Statement of Opportunities (ESOO) report, which provides a 10-year outlook on the reliability of the National Electricity Market (NEM). The report reveals that a record-high 4.4 gigawatts (GW) of renewable energy generation and storage capacity was brought online in the NEM during the financial year 2024-25, compared to the average of 3.2 GW in the previous three years.

Key Takeaways:

• A record 4.4 GW of renewable energy generation and storage capacity was brought online in the NEM during the financial year 2024-25, outpacing the average of 3.2 GW in the previous three years.
• The report forecasts that between 5.2 GW and 10.1 GW of generation and storage capacity will come online in each of the next five years to offset planned retirements of coal-fired power stations.
• The increase in renewable energy capacity has closed forecast reliability gaps in Australia's two most populous states, New South Wales and Victoria, when major coal-fired plants are set to shut down in 2027-28 and 2028-29, respectively.
• A small reliability risk remains for the northeast state of Queensland for the upcoming summer due to project delays and forecast elevated demand, as well as for South Australia in 2026-27 due to delays in building a major transmission link and the closure of a gas-fired power station.
• A recent agreement between the gas plant operator and the state government to potentially extend its operating lifespan by two years was not factored into the forecast reliability gap in South Australia, which is now reduced but still a concern.
• The report emphasizes that the timely delivery of new generation, storage, and transmission, along with the operation of consumer energy resources to support reliability, remains critical to ensure energy reliability over the next decade.

Statistics:

• 4.4 GW: Record-high renewable energy generation and storage capacity brought online in the NEM during the financial year 2024-25.
• 3.2 GW: Average of renewable energy generation and storage capacity brought online in the previous three years.
• 5.2 GW - 10.1 GW: Forecasts of generation and storage capacity to come online in each of the next five years to offset planned retirements of coal-fired power stations.
• 11 GW: Combined electricity supply from predominantly coal-fired power stations that will retire over the next decade.
• 2027-28: Forecast reliability gap closed in New South Wales when major coal-fired plants shut down.
• 2028-29: Forecast reliability gap closed in Victoria when major coal-fired plants shut down.
• 2026-27: Small reliability risk remains for South Australia due to delays in building a major transmission link and the closure of a gas-fired power station.
