ENERGY SECURITY

Temperature extremes exacerbate energy insecurity for Indigenous communities in remote Australia

For remote Indigenous communities prepaying for electricity in Australia’s Northern Territory, temperature extremes increase reliance on the services that energy provides and the risk of disconnection of those services. Policy should focus on reducing the frequency, duration and negative impacts of disconnection, within the context of a warming climate.

Messages for policy

  • Electricity disconnections among households with prepayment meters are more frequent during temperature extremes, curtailing access to essential services.

  • Households with high electricity use experience more disconnection events, so policy responses should account for household structure and occupancy, as well as the opportunity to use rooftop solar.

  • Greater visibility and understanding of data on disconnections in these communities is needed to determine the extent of their energy insecurity.

  • Policy should seek to reduce the frequency and duration of involuntary self-disconnections in remote communities, particularly during extreme temperatures.

  • To account for the multifaceted nature of energy insecurity, policy responses need to be informed by residents, local councils, healthcare professionals and other relevant organizations.
