StRAtegic Objectives<br />
STRATEGIC OBJECTIVE 3 – IMPROVE CUSTOMER VALUE<br />
2010–11 Objective 2010–11 Target 2010–11 Result<br />
• Set a course for a<br />
sub-70-minute SAIDI.<br />
• Implement rapid response<br />
teams for our network.<br />
• Limit unplanned supply interruptions<br />
for our average customer to less than<br />
87 minutes.<br />
• By April 2011.<br />
• Unplanned supply interruptions for<br />
our average customer was 72 minutes.<br />
• Completed: half <strong>of</strong> the rapid response<br />
crews have been established and<br />
are working well, with the remaining<br />
positions expected to be filled in the<br />
near future.<br />
Reliability performance<br />
– a record result<br />
Reliability <strong>of</strong> supply is an important<br />
measure by which we demonstrate<br />
our network performance and ensure<br />
we can deliver value for customers.<br />
We measure the reliability <strong>of</strong> our<br />
network with the System Average<br />
Interruption Duration Index (SAIDI).<br />
This is a measure <strong>of</strong> the number <strong>of</strong><br />
unplanned minutes that customers,<br />
on average, are without electricity<br />
each year. This excludes the impact<br />
<strong>of</strong> significant storms.<br />
We achieved our bestever<br />
performance in<br />
network reliability and<br />
are one <strong>of</strong> the most<br />
reliable distributors<br />
in Australia with an<br />
unplanned SAIDI <strong>of</strong><br />
72 minutes.<br />
Our SAIDI target for the year<br />
ending June 2011 was 87 minutes,<br />
but our actual result for the year<br />
– excluding significant storm<br />
interruptions permitted under our<br />
licence conditions – was 72 minutes.<br />
Our ongoing reliability improvement<br />
programs combined with mild<br />
weather patterns throughout the<br />
year contributed to this positive<br />
result for customers.<br />
Events that had a significant<br />
impact on the overall reliability<br />
result include:<br />
• 16 interruptions to zone and<br />
sub-transmission substations<br />
contributed to approximately<br />
1.3 minutes <strong>of</strong> SAIDI.<br />
• 29 sub-transmission electricity<br />
line interruptions contributed to<br />
2.5 minutes <strong>of</strong> SAIDI.<br />
• 734 distribution electricity line<br />
interruptions contributed to<br />
50 minutes <strong>of</strong> SAIDI.<br />
<strong>Endeavour</strong> <strong>Energy</strong> is well-positioned<br />
to establish a sub-70-minute SAIDI<br />
as a normal part <strong>of</strong> doing business.<br />
To support this effort, our reliability<br />
improvement projects will focus<br />
particularly on distribution electricity<br />
lines that contribute more than<br />
0.3 minutes to <strong>Endeavour</strong> <strong>Energy</strong>’s<br />
overall SAIDI performance.<br />
Implementing rapid<br />
response teams for<br />
our network<br />
<strong>Endeavour</strong> <strong>Energy</strong> has established<br />
rostered rapid response teams to<br />
attend network incidents that occur<br />
outside normal Monday to Friday<br />
working hours. Historically these<br />
incidents required employees to<br />
be called out, at overtime rates,<br />
to restore power or ‘make safe’<br />
the network.<br />
Our rapid response crews provide<br />
valuable support in our efforts<br />
to respond to customer outages.<br />
This has helped us to:<br />

• Manage employee fatigue.<br />
• Reduce the need to disrupt<br />
planned construction and<br />
maintenance activities.<br />
• Ensure our employees can be<br />
on site as soon as possible.<br />
• Reduce our cost to serve<br />
for customers.<br />
