The power system may experience different types of power outages. Load shedding is different to local outages (planned or unplanned).
Load shedding is a last resort response by the Australian Energy Market Operator (AEMO) to maintain system security, mitigate damage to infrastructure and to protect customer equipment. It’s the controlled reduction of electricity supplied to homes and businesses to securely manage the wider power system.
Planned outages are undertaken by Western Power and are prearranged and necessary for routine maintenance, inspections and improvements on various electricity infrastructure.
Local unplanned outages are an interruption to the transmission or distribution of electricity that is unscheduled and can occur as a result of range of causes including: damage to wires caused by storms, lightning strikes, falling trees (or branches), motor accidents, bushfires, and equipment failure.
