ONE millimetre is all a giant tower crane had to play with in the act of lowering a 24-tonne turbine into place at Bogong Power Station yesterday. The precision placement took just 20 minutes to complete but more than four days of preparation. It was a critical milestone for the $250million project that is now on track to generating its first electricity in less than 12 months.An AGL project spokesman said the second turbine would be lifted into place in weeks. "These milestones are critical, if they slip we jeopardise the end date of the whole project," he said. "That was the first of two, the second expected to be here in the first week of July. "But as it stands we are on track for first generation in June next year and the project being completed by September." The turbine was manufactured in China and brought straight from Melbourne dock to the power station.
The AGL spokesman said there was no room for error in yesterday's operation. "it didn't take long to load but tour days' preparation for the foundations and it has to be positioned with accuracies of less than 1mm," he said A 45-tonne tower crane was used to load the turbine. "We had to use a tower crane similar to those on high rise sites," he said. AGL's 140Mw hydro power station on Lake Guy, between Mount Beauty and Falls Creek, is the biggest addition to the Kiewa hydro scheme since the 1960s.
