(a - c) Please refer to [Tabled Paper No]
(d) Most unplanned outages during these periods have been due to equipment failures. Some outages have also been attributed to termite activities in underground cables.
Since 2009, 3 outages were caused by severe weather conditions. One incident was caused by a machine (third party) which hit an underground HV cable while excavating.
(e - f) As the equipment failure issues were caused by underground cable joints and termite activities, targeted reinforcement work has been undertaken with 4.5km of underground cable replaced with more termite resistant cables.
Western Power has an asset replacement program that replaces assets based on their condition (determined using a regular inspection process). As a part of this program, Western Power will replace or maintain assets that are assessed to have a significant risk of failure.
