Network Strategy<br />
Network business objective<br />
Provide long term customer service by developing and operating a sustainable and reliable network<br />
Network business target outcomes and strategies<br />
Optimise network capacity<br />
through effective demand<br />
management and investment<br />
for security and growth<br />
Meet customers’ reliability needs<br />
through better management <strong>of</strong><br />
planned and unplanned outages<br />
Provide customers with value<br />
for money over the long term<br />
by improving the effectiveness<br />
and efficiency for capital and<br />
operating programs<br />
• As land use continues to shift<br />
from rural and semi-rural to<br />
urban and light commercial,<br />
customers expect improved<br />
reliability performance.<br />
• Peak temperatures across the<br />
network are typically higher and<br />
stay high for longer than those<br />
<strong>of</strong> central Sydney and other<br />
coastal areas.<br />
• Eighty-one percent <strong>of</strong> households<br />
in Greater Western Sydney now<br />
have air conditioning units,<br />
compared with 51% in the Illawarra<br />
and 50% in the Blue Mountains.<br />
This has resulted in a ‘peakier’ load<br />
pattern in hot weather requiring<br />
more assets to service demand<br />
that only exists for a short time<br />
each year.<br />
• The uptake <strong>of</strong> other appliances<br />
such as televisions, in-home<br />
computers and entertainment<br />
systems. This trend is also<br />
changing consumption patterns,<br />
resulting in heightened customer<br />
expectations and awareness about<br />
reliability and security <strong>of</strong> supply.<br />
• Many network assets were built<br />
in the infrastructure boom <strong>of</strong><br />
the 1960s and 1970s and are<br />
approaching the end <strong>of</strong> their<br />
useful lives.<br />
Major projects approved by the Board during 2010–11<br />
In response to growing demand and the need to renew ageing assets, 12 major projects for a total <strong>of</strong> $206.9 million<br />
were approved by the Board this year. Construction will commence in coming years.<br />
