The reliability of generating units be estimated based on planned maintenance activities on an annual basis in addition to an allowance for unplanned outages. This has not occurred. The PWC availability estimates for all machines are 92 per cent and do not consider past experience with particular machines or planned maintenance activities. PWC re-assess the reliability of the Tennant Creek generating units taking into account the substation refurbishment and attendant control gear upgrade. These upgrades are in progress. PWC provide more exhaustive detail in regards to the options considered, including engineering review, financial and time considerations in relation to its proposed network projects. These details have not been provided to the Commission. The Commission recognises that this detailed information may not belong in the network management plan. This information should reside in separate reports and be referenced in the NMP. Urgent planned replacement of the switchgear at Tennant Creek. Completed. PWC consider what action is required to address the increase in number of customer calls and improve the associated level of customer service. This item remains an issue and is re-raised in this PSR PWC further consider the character and content of the Network Management Plan to progress alignment with NEM practices. No significant progress has been made PWC consider employing effective engineering solutions to improve the performance of network feeders 11PA17 Thorngate and 22TC602 Feeder 6. According to the NMP these two feeders are no longer poorly performing feeders PWC provide in future review, further details of the poor performing feeders including time to restore the feeder for each outage and specific details of the faulty equipment. PWC did not provide details and the Commission did not request them. However, it is noted that performance of the poorest feeders has improved significantly and this is no longer a major issue. Carried-over from 2011-12 PSR Recommendations Continued development of electrical models, particularly in the DarwinKatherine and Alice Springs systems, to identify both This work is ongoing and needs to be accelerated.
