How is climate change likely to affect queensland electricity infrastructure into the future?

In order to plan efficiently and cost effectively, utilities must take a long-term outlook on their transmission and distribution utility assets. Climate is important to consider, especially when a significant proportion of Queensland is affected by extreme weather events including cyclones, flooding and heat. However, why the climate is changing is due to human-related activities. Therefore, a study was performed to identify the changes which could be expected to occur in Queensland, and how this may affect utility operations. Literature provided by various government bodies and utilities was reviewed and analysed. The study highlighted several instances where direct damage to infrastructure will increase due to tropical cyclones and flooding, requiring adjustments to utility asset management plans. It is likely that this will result in more frequent electricity supply interruptions. Additionally, increasing summer temperatures and heatwaves due to climate change will increase peak load demand. Additional generating capacity may be required to meet this demand.
