Energy supply disruptions can occur either due to technical failures or major physical damage to infrastructure, such as power plants, transmission or distribution networks.
Gas, electricity and liquid fuel supply losses can contribute to energy supply disruptions.
Examples of significant events in Victoria include:
- 28 and 29 January 2018 - high demand from sustained high temperatures and humidity overloaded localised electricity network assets causing power outages.
- 31 January 2020 - severe winds caused damage to eight transmission towers causing blackouts.
