We can all remember the 2011 Brisbane floods when over 20,000 homes were impacted and residents had to be evacuated. During the flood event, Energex switched out 25 zone substations and 157 distribution feeders and had to replace many distribution transformers, poles and electricity meters. Energex was required to set new design standards for its substations and equipment and undertake flood resilience work to ensure assets would withstand a future Defined Flood Event.
The Energex electricity network only covers 3% of the land mass of Queensland but can be significantly impacted by severe weather events such as floods and bushfires.
In December 2013, lightning sparked bushfires on Stradbroke Island which lead to the burning of 60% of the vegetation and causing widespread network damage. Energex responded to the event by deploying over 100 staff and had to replace a number of transmission and distribution poles.
This presentation will give you an insight to Energex’s bushfire and flood risk management plans and the lessons learnt from the 2011 floods and the Stradbroke Island bushfires. These risk plans outline the risk identification, preparation, resilience initiatives and operational response to these events. Energex has collaborated with Queensland Fire and Emergency Services to develop communication protocols and has participated in joint exercises for severe weather events.
