Senator FOREMAN —In accordance with the provisions of the Public Works Committee Act, I present the report relating to the 132 kilovolt subtransmission development at Tuggeranong, Australian Capital Territory.

Ordered that the report be printed.


Senator FOREMAN —by leave-The Australian Capital Territory Electricity Authority purchases electricity from the Electricity Commission of New South Wales and the Snowy Mountains Hydro-electric Authority. Once received at the bulk supply substation at Holt electricity is distributed throughout the Australian Capital Territory along a system of 132,000 volt subtransmission lines to zone substations, where it is transformed to 11,000 volts and then fed into residential and commercial areas where it is further transformed to a more usable voltage. The Tuggeranong Valley is one of the most rapidly developing areas of Canberra. Predictions indicate that the population of the valley will increase from its present 43,000 people to 62,600 by 1988 and will possibly peak at 100,000 during the late 1990s. The valley is currently supplied with electricity from a zone substation at Wanniassa, which reached 95 per cent of its capacity during the last two winters. Clearly if development is to continue the provision of additional electrical power is essential.

The proposal is for the construction of a zone substation at Gilmore and for the erection of 20 kilometres of high voltage subtransmission line to connect it at zone substations at Wanniassa and the Causeway. The Australian Capital Territory Electricity Authority prepared an environmental impact statement on the proposal and delivered copies of it to all persons and organisations who may have been affected by the proposal. The Authority examined all responses and compiled a final environmental impact statement which was subsequently cleared by the Department of Home Affairs and Environment. The Committee is of the opinion that the proposal meets all the relevant criteria and recommends that the work proceed.
