Senator McGRATH (Queensland—Assistant Minister to the Prime Minister) (16:17): I seek leave to make a short statement. The DEPUTY PRESIDENT: Is leave granted? Leave is granted for one minute. Senator McGRATH: With respect to networks, the Australian Energy Regulator, in their benchmarking studies, have consistently found that privately owned networks are more efficient and productive than government owned ones. Regarding generation, at the time of the blackout wind was supplying around 2.5 per cent of demand. Had wind been producing at its capacity, it would have supplied over half of South Australia's electricity needs and there would have been around 1,400 megawatts of spare capacity. The other 97.5 per cent was being met by gas fired generation and brown coal from Victoria. Question agreed to.
