(1) As at 12 August 2010, 19,090 poles require either replacement or reinforcement.
(2) 38,350 poles are planned to be replaced or reinforced in total, 12,190 in 2010/11 and 26,160 in 2011/12.
Additional funding to meet asset maintenance and replacement will be managed through the business case process as outlined the 2010/11 State Budget.
(3) The expected design life of a pole is 35 years. This can be extended to 50 years by installing a steel reinforcement. About one half of the wood pole population is currently reinforced.
(4) There is a range of pole ages from 0 to 52 years, the average being 31 years. Western Power's strategy for the management of the pole population is based on condition based maintenance. The condition of a pole determines whether it is suitable to remain in service or is replaced, or reinforced to extend its design life. This decision is not based only on age.
(5 - 6) Western Power delivers its annual work program using a Balanced Portfolio delivery strategy that consists of its internal workforce, Strategic Alliances and Preferred Vendor arrangements to maximise value and minimise delivery risk.
Under that strategy, smaller contractors can be engaged in a variety of circumstances, although not directly through Western Power.
