Energy production and transmission is expensive, requiring multimillion-dollar equipment as well as the need for high numbers of personnel to complete operations. Electricity is generally transported via transmission lines in order to be distributed to end-users. Natural disasters that affect these transmission lines can have severe impacts on personnel safety and the wider community. Equipment and resources that are essential to the generation and transmission of electricity can be impacted. Delays in production and transmission of electricity can leave towns, cities and states without energy, affecting their daily activities, transport, medical services and businesses. Electricity transmission delays that occur as a result of equipment failure or injury to personnel can impact the timeline of recovery for a business and its profitability, affecting the interests of stakeholders and its reputation. Some extreme natural disasters such as cyclones and bushfires can not only disrupt these lines but can also limit accessibility which can then further prevent the restoration of power.
While it is rare for electricity transmission lines to face outages, when experienced, they can have great impacts on the wider community. Examples include:
