Mr WEST (Minister for Housing and Construction)(10.38) —I move:

That, in accordance with the provisions of the Public Works Committee Act 1969, it is expedient to carry out the following proposed work which was referred to the Parliamentary Standing Committee on Public Works and on which the Committee has duly reported to Parliament: 132kV subtransmission development, East Tuggeranong, ACT.

To cater for the urban expansion of Canberra's Tuggeranong area the Australian Capital Territory Electricity Authority requires the construction of a substation and associated transmission lines. Tuggeranong is extending southwards and is expected to peak with a population of about 92,000 by the late 1990s. As a result of this urban development, the number of houses in the area will more than double, increasing the demand for electrical power. The continuing growth of the Hume industrial area and the establishment of the Tuggeranong Town Centre will also contribute to the demand for electricity. Ultimate power demand for Tuggeranong is estimated to be 170 to 200 megawatts, based on 1.8 to 2 kilowatts per head of population and 10 to 20 megawatts drawn by commercial and industrial interests.

At present, the sole source of supply for the Tuggeranong Valley is the Wanniassa sub-station which also provides about 40 per cent of the electrical requirements of Woden Valley and Weston Creek. Therefore, an additional electrical power supply is essential. The proposal comprises the addition of two 132kV line bays at the Gilmore zone sub-station; twin 132kV sub-transmission lines along a seven kilometre route from the Gilmore zone sub-station to a new zone sub-station site on the common boundary of the suburbs of Theodore and Conder; and a zone sub-station consisting of a switch yard and control building on a 1.75 hectare site in a saddle between Theodore and Conder. The estimated cost of the work is $6.24m based on March 1986 prices and about 40 to 50 people will be employed on this worthwhile project. I wish to thank the Public Works Committee for its prompt co-operation and I commend the motion to the House.
