1 Distribution businesses are required to give their customers four business days’ notice of any planned outages, so they can prepare to deal with loss of electricity. The Businesses typically mail (or letter drop) a letter and brochure regarding planned outages well before the four business days’ notice requirement. In addition, the Businesses send SMS notifications to customers if the Businesses are in possession of their mobile phone numbers. The Businesses are committed to a Hot Day Action Plan ( HDA ) which encompasses strategies to be employed on days of extreme fire weather conditions. For Total Fire Ban ( TFB ) days, the Businesses proceed with planned works under certain conditions including, for example, starting work at 6am with the aim of finishing work by 11am. This ensures customers experience a short period off supply under tolerable conditions, given the temperature rarely exceeds 40 degrees by 11am. Additional resources are also organised for these works to ensure they are completed as quickly as possible. DSDBI have asked stakeholders to respond to the questions below. How will the proposed restriction impact on the operations of distribution businesses? As noted, the Businesses consider restrictions of planned works during very hot days could potentially increase safety and bush fire risk and possibly place the Businesses in breach of its bush fire risk maintenance requirements. Further, there is potential for an increase in unplanned System Average Interruption Duration Index ( SAIDI ) due to the reduction in the number of days the Businesses can effectively maintain the network. This could have an impact on the Businesses’ reliability performance and unduly penalise the Businesses through incentive schemes implemented by the Australian Energy Regulator ( AER ).
