Just ran an update as at 31 July – several Water Corporation stations look suspect – several BoM stations are out of date by months. My spreadsheet showing audit required.Source of BoM data and map – for a years daily data enter the 6 digit BoM station ID alongside Station number then click the Get Data button.

In May I reported – West Australian Govt Water Corporation fails to record March 2016 rain at several dams
Dug out of my files this 9 page April 2012 pdf from the CEC titled “There’s power in wind: national snapshot” – easily found by Google.
They have a few pages of statistics showing how marvellous wind power is at solving Australia’s problems. This screenshot from p 2 shows that if all “proposed” windfarms were built they would power 6,236,602 “equivalent homes”.
I thought that was a big number and sure enough the ABS in 2012 said there are ~10 million homes in all Australia.
I am hoping some readers can check other CEC claims from 2012. Such as – wind power saves “…around 1 tonne of greenhouse gas for every megawatt-hour (MWh) produced.”
Moving on I see the CEC is still in existence – and have a new report out “Time for honest discussion about energy in South Australia”. At first glance looks a shocker too. They claim ” There is a very strong correlation between wholesale electricity and gas prices in South Australia.”
I would say – Post the closure of coal generation on 9 May 2016 – and at times of poor wind output – gas generation and imports are relied upon to meet demand. Increasing gas consumption in electricity generation will have a consequence of putting upward pressure on gas prices. Not the other way around as CEC claims.
The AEMO price blowouts that flowed from the 9 May 2016 shutdown of South Australian coal fired power stations make it imperative that Australia take stock of where we are on our +decade long transformation of our electricity grids. South Australia with the largest proportion of wind power in Australia is so obviously dependent on increasing coal based power imports from Victoria that we must call a halt to further degrading our vital power grids. Check NemWatch
There must be no more reckless expansion of wind power before we can lay out in public a clear engineering certified and costed pathway to 24/7 lower carbon power.
A Royal Commission into the entire MRET Scheme disaster would be hugely beneficial. Prev blogs on post May AEMO price explosion – Australian electricity bills set to soar
This NemWatch screenshot shows how wind is completely useless at times. Unless we shut the Nation down during wind droughts we need to keep a full complement of reliable generation ready to go at any time.
Australia runs on coal. See how South Australia is pounding their gas plants – even firing up some diesel to cope with the morning rush. Comparing their AEMO demand with NemWatch shows they must be importing about 200MW from Victoria.

Read and weep – Review of market frameworks for power system security 14 July 2016 – No mention of “Elephant in the Room” sky-rocketing AEMO Regional Reference Prices in South Australia, Vic, NSW & Qld.
Quotes in italics –
Challenges in maintaining power system security are emerging because of the physics of maintaining technical generation parameters like voltage and grid frequency. And this was not predicted?
Conventional electricity generation, like hydro, coal and gas, operate with large spinning turbines that are synchronised to the frequency of the grid. These generators support the stability of the power system by working together to maintain a consistent operating frequency. And no electrical engineer told you this before the Grid was infested with wind turbines?
Less conventional forms of electricity generators, such as wind and rooftop solar, are not synchronised to the grid and are therefore limited in their ability to dampen rapid changes in frequency or respond to sudden large changes in electricity supply or consumption. This is no surprise to electrical engineers.
Why not sack the useless AEMC – get some engineers in to chart the future of the grid – wind back the uptake of subsidised renewables – make sure any future renewables pay their own way including the full cost of the grid coping with their production.
So innovative and excited Malcolm gets to be PM with a micro-majority. Every day praying there will not be a cessation of heartbeat somewhere in Govt ranks leading to a byelection or that some obscure Govt MP will not accept a Labor bribe to rat on his mates and desert Govt ranks. Looking ahead to Senate results is all we have left in this dismal scene. What is propping up the AU$ I can not imagine. And every day the sun rises the ALP-ABC will be generating anti-Govt – pro-GreenLabor “news”.
At 10.35am AEST Nemwatch shows SA burning diesel to generate 91MW to contribute to a Region Total Demand of 1,992MW. However AEMO at the same time – says SA demand was just under 1,600MW – which I see as evidence that just over 300MW were being exported to Vic. I assume it pays SA to pay the diesel and gas costs to keep exports up because at times of abundant wind in SA the AEMO Regional Reference Price can go negative.
RetractionWatch.com reports – The authors of two environmental papers, including one about the effects of fracking on human health, have retracted them after discovering crucial mistakes. The ABC reports – Labor MPs call for ban on fracking in WA’s South West amid community concern – The ABC quotes some fair comments on fracking by retired geologist Peter Lane but hides them right at the end of the article.
