TransGrid Publishes Final Report: Supply to the Wagga Area

16 March 2007

The Wagga area includes the local government areas of Wagga Wagga and Lockhart and parts of the Junee, Coolamon, Gundagai and Greater Hume local government areas. It has a population of around 70,000.

TransGrid and Country Energy are proposing the construction of a new large transmission network asset to increase the capacity of the transmission network supplying the area. In accordance with clause 5.6.6(h) of the National Electricity Rules a final report has been prepared that applies the AER?s regulatory test to a range of reasonable options to meet this requirement.

The proposed actions are that:

• TransGrid constructs Wagga North 132/66 kV substation by summer 2009/10. These works are estimated to cost $21 million (+/-25%);
• Country Energy proceeds with the planned rearrangements of its 66 kV network utilising Wagga North 132/66 kV substation as a 66 kV source of supply; and
• Country Energy constructs a 66 kV feeder to supply its Holbrook, Henty, Culcairn and Uranquinty substations from Wagga 132/66 kV substation to meet reliability of supply requirements for those sites. These works are estimated to cost around $2?million.
