Offshore wind is unlikely to make a significant contribution to Victoria’s energy supply until well into the 2030s if not later, say experts, casting doubt on the ability for the emerging sector to play a part this decade in replacing closing coal power stations.cited the state’s big expansion in offshore wind as one reason it can rule out coal and gas power plants from the “capacity” mechanism for the National Electricity Market.
That leaves the technology reliant on other benefits such as scale and greater consistency of generation to offset the cost disadvantage.A CSIRO report last year put the likely capital costs of offshore wind in 2028 at $5356 per kilowatt of capacity installed, almost three times higher than onshore wind at $1915/kW. But in this year’s draft report the estimate falls to $4085/kW, still more than double $1755 for onshore wind.
“It is therefore not currently projected to play a large role in the future energy mix at current forecasts of future costs, unless land use considerations limit onshore development. Further, cost reductions could see offshore wind feature more prominently in future ISPs.”The final 2022 ISP – due to be released on Thursday – will include AEMO’s latest thinking on the sector.
“While there has obviously been a long wait in Australia for the legislation, and you’ve got all the normal development hurdles, once you’ve got that it is significantly faster to install than onshore wind,” Mr Gleeson said. He pointed to the experience in the UK, where offshore turbine installations are completed in 18 hours compared with about two weeks for those onshore.
in EU they use the shores but Oz is different we r surrounded by sea so build them on isolated cliffs
Victoria is just peeved that it's losing its central role in Aus energy generation.
More expensive than nuclear with the same intermittency of other renewables. The absurdity of offshore wind confirms RE is driven by ideology & not economics.
baseload Australia urgently needs to develop new baseload power. Poor and middle class are going to get crushed
I’m sure maintaining offshore wind turbines in a marine environment would be barely an inconvenience
I speak for ALL Australians when we say nuclear is the way forward
