Australia's AEMO forecasts tight electricity supply in winter 2019-2020

The Australian Energy Market Operator (AEMO) has released its 2019 Electricity Statement of Opportunities (ESOO), which forecasts a high risk of expected unserved energy (USE) and greater risks of load shedding over the next 10 years.

For the upcoming summer 2019-2020, the AEMO highlights the need for additional reserve resources, due to peak summer demand, in a context of degraded reliability of ageing thermal power plants. The state of Victoria would risk blackout if the unplanned outages of two major power plants, 500 MW Loy Yang A2 and 259 MW Mortlake, continue until the summer. The ^lants are scheduled to return to service in late December 2019.

After 2020, the power supply will be impacted by the gradual retirement of the Liddell coal-fired power plant in New South Wales (NSW) (one unit to be shut down in April 2022 and remaining units to follow in 2023-2024). Nearly 5 GW of committed new power generation projects and upgrades to existing power plants are expected to be commissioned in the next three years and will be complemented by the 2 GW Snowy 2.0 hydropower project.
