The SA State Govt elected with only 47% of the two party preferred vote due to the gerrymandered electoral system – now crows about adopting a target of 50% renewable energy by 2025. SA has gone heavily into wind power and the only way this 2015 target For example: Your teen can take the course buying viagra in usa at your own pace and on your own time.

It is a shame that the other states would not sever the grid at the Vic border – leave the South Australian Labor Govt to figure out how to generate electricity on their own.
S.A. increasingly sounds like an Australian version of the failed Californian experiment. Cut off at their respective state borders, such high levels of low inertia intermittent generation (renewables) would render both of these state power grids uncontrollable and hence unviable.
Just can’t wait for the interview of a Green Senator on the day they are forced to evacuate high rise buildings in Adelaide after the power blacks out!
50% renewables by 2025? Oh, they mean 50% of ELECTRICITY by 2025. Any ideas as to what porportion of SA’s total energy consumption is in the form of electricity? My guess would be less than 25%
It isn’t only propped up by interstate coal fired generators. SA’s renewable generation is already propped up by the RET and green energy buyers to SA’s east. Most of the wind power produced in SA is used there, the greater part of the subsidy needed is paid by others. Planned expansion of wind power in SA is the reason why the ability to transfer electricity between SA and Victoria in both directions is being upgraded.
Worth noting that the ACT has a “90 per cent target for the use of renewable energy (electricity) in the ACT by 2020.”

These documents may provide some more perspective to the S.A. renewables fiasco:
Australian Energy Market Operator (2014) South Australian Electricity Report
German Power Grid More Vulnerable Than Ever
Bob in Castlemaine:
A very interesting report. Based largely on wishful thinking from a cursory glance.
They propose adding 1904 MW of wind capacity, with 720 MW gas and 523 MW geothermal (if that happens) to balance it. Since they are already drawing 12% of usage from Victoria, they are going to need more from there. At a minimum another 660 MW yet they are only adding 190MW to the Heywood link, and apparently the rest will be covered by OCGT. A hot summer like 2010/11 when the links from Victoria had to be used at lower capacity because of thermal overload and there will be blackouts.
I think I’ll start looking at a diesel generator.
To reach the Labor 50% renewables target by 2025 it looks as if they would need rooftop solar to keep booming – the AEMO report deals with RT solar on pages 17 & 18 –
Figure 14 does not bother with RT Solar and does not show wind increasing enough by 2025 for renewables to top 50%. Hopefully the new Commonwealth Govt will put the squeeze on wasteful taxpayer subsidising of renewables.
Warwick,
I give up on this report. In the opening paragraph they state:
“The Australian Energy Market Operator (AEMO) has assumed existing generation remains available”.
Since the only coal fired station is slated for shut down, indeed was at one stage but hastily reinstated due to inadequate wind performance, and is being run at 45.2% capacity (their claim, but the figures work out 43.9%) which uneconomic use will only hasten its final shut down, this is questionable.
The rest of the document shows what a dismal state SA is in. It must be the only State expecting declining industrial, commercial and household electricity consumption. But the calculations on the future are all worked on that premise.
I gave up when it claimed (via production figures) that the wind farms ran at an average 36% capacity. That puts SA ahead of offshore farms in the North Sea.
Basically the State depends on gas. The Osborne station – I assume CCGT – runs at 93.3% capacity. No other gas station is anywhere near that figure yet they claim an overall average for gas of 95.6%.
Solar PV estimated C.F. 14.1%.
They cannot rely on wind to meet Peak Demand on hot days in summer as the turbines aren’t allowed to run when the temperature exceeds 38℃ because of the danger of fires from overheated lubricant. For all that the report assumes 8.7% of the wind capacity to be available AT ALL TIMES in summer 2014/15. Curiously the figure for the future drops to 6.9%, which is about 6.7 too high in my opinion.
My summation; the writers were told to prepare a report showing that 50% renewables were possible, and that’s what came out.
