Network maintenance
Our Strategic Network Maintenance
Plan (SNMP), which is part of our
Strategic Asset Management Plan,
analyses maintenance needs against
business objectives and details
the strategies we require to ensure
assets meet our network strategy.
This work includes vegetation
management, asset inspections and
pre-summer bushfire inspections
of our overhead electricity lines in
bushfire-prone areas.
The plan is reviewed and updated
annually to identify what network
maintenance activities will be
needed over the ensuing 12-months.
In 2010–11, Endeavour Energy
achieved the delivery of a record
maintenance program at a cost
of $226.4 million, compared
with our 2009–10 expenditure of
$211.1 million, and 94% compliance
with our maintenance target.
Our maintenance performance
contributed to our continued
improvement in system reliability
at 72 minutes lost per customer
per year.
Maintenance activities and
expenditure this year included:
• $21.3 million on vegetation
management to maintain safety
clearances, reduce outages,
improve reliability and manage
bushfire risk.
• $16.7 million on metering
including the reading of meters
and to provide information for
billing purposes.
• $16.3 million for fault and
emergency work following
weather related events and third
party incidents.
• $14.2 million on preventative
maintenance and inspections
on the transmission and
distribution network.
• $14.2 million on condition
based maintenance.
• $10.6 million for expenses related
to the contestable customer
connection works including
transformers and switchgear paid
by the customer.
• $6.8 million for the overhead line
and pole inspection program,
involving the inspection of
93,108 poles.
• $6.6 million on street lighting
including replacing 62,033 lamps.
• $119.5 million largely on network
operating overheads and other
maintenance activities.
