Media reports say Alinta will close their coal fired generation at Port Augusta in May 2016. SMH and ABC – Last month I blogged – Will South Australia walk the talk and close their coal fired electricity generation? Since then I have obtained 12 months of daily South Australia electricity data and on Adelaide hot summer days when wind is not stellar it looks difficult to meet demand without coal.
I am looking for a period of 5 minute data to check this further. Thanks to Peter Bobroff from the grid.publicknowledge.com.au site for these data.
About time somebody got pinged considering claims made by renewable energy advocates over more than a decade. At a time when Hydro is saddled with the Basslink failure – I bet behind scenes unprintable.
Momentum Energy ads falsely claimed power generated ‘from thin air and fresh water’, ACCC rules
Check the brilliant little NemWatch to see in real-time how much renewable energy is being generated State by coal burning State
Here is the ACCC media –

I have been saving NemWatch screenshots offline for a few months now to get a handle on what the three NSW large solar power plants actually produce out of their rated capacity of 211MW. Plants are at Nyngan 102MW & Broken Hill 53MW – and Moree 56MW. I made 69 readings, mostly in March (36). If there are more than one per half hour slot – then they are averaged.
AGL’s Nyngan and Broken Hill plants combined are expected to produce 359,000MWhours of electricity per year which equals 40.98MW on a 24/7 basis.
Last October South Australia was talking big about closing their last coal fired power stations near Port Augusta in March 2016 – Alinta to shut SA coal mine, power plants early – we will see. What do readers think? This chart of daily generation shows they would have to work their gas fired units much harder if coal closed.
NemWatch lets you see real time generation sources but does not show imports and exports. Thanks to Peter Bobroff from the grid.publicknowledge.com.au site for these daily data which reveal much.

The last day of Basslink transmissions was 20 Dec 2015. It is fascinating that the cable failed a few days after exports were started. What was the rationale behind the decision to sharply increase Hydro production 16-17th December to export to Victoria – at a time dam levels were low? After Basslink failed it took a month to ramp up gas. Will try and get intraday day data in the week up to the break. A week ago I posted – “Base Load power is now a myth” so say renewable energy enthusiasts
Checkout NemWatch for real time electricity generation in each State and see how often wind is near useless.
The pre-Christmas 2015 failure of the Basslink cable from Victoria has thrown a googly into Tasmanian electricity supply. Most of their supply is from Hydro, the last two years rain has not been stellar and storage levels are under 17% now. They have gas supplies from Gippsland and have gas fired generators. Nemwatch gives real time snapshots of what each source is contributing. Wind has less capacity than gas – thats when the wind blows. The State Govt which owns the Hydro and most other generation – is importing 200 diesel units to help through and the unions want their share. Then they can always turn off industrial customers if they have to. Basslink is taking longer to repair than was first thought.
Scanning news headlines I discovered that the fault in the BASSLINK cable has not been found yet so there will be delays to the repairs timetable requiring the Tasmanian Govt to order 200 diesel generators. Upshot is the cable repair ship has not pinned down the fault location yet. Anyway – that nudged me to check NEMWATCH for the first time this month and the result at 4pm AEST 12 Feb 2016 is below.
Wind across Australia generating only 470MW. How has this taxpayer subsidised economic monstrosity been foisted on Australia and continues to be expanded? Answer is a combination of – Green Lies – GreenLeft media – gullible politicians – voter apathy. There are many days when wind generation is very poor.
This research by Chinese scientists in Hefei is reported in Nature – Partially oxidized atomic cobalt layers for carbon dioxide electroreduction to liquid fuel
and Popular Mechanics – Breakthrough Material Is a Better Way To Turn CO2 Into Clean-Burning Fuel.
Could a process such as this be a basis for making CCS (Carbon Capture & Storage) more worthwhile?
The ABC have this article claiming – Rooftop solar producing more energy than WA’s biggest turbine – Curtin University sustainability professor Peter Newman said – “It’s nearly 500 megawatts and it’s growing rapidly,..” Yet when I check NemWatch for WA I can only ever find a little over ~250MW for WA small solar. Is this because about half the output is used in the homes of the owners of these rooftop solar systems?
And of course the article seems to forget that these solar systems only work in the sunny hours – they make no electricity at night while the coal fired generators chug away 24/7. I wonder to what extent the WA grid can keep on accommodating increasing solar and wind power yet remain stable. I also wonder what is the cumulative cost of all the small scale solar subsidies paid out by the various Australian Governments.
They are instrumental in inflicting this disaster on us all – utterly no shame. New year rings in 41 per cent rise in GreenPower prices
Has anybody got any other increases to quote. How about us that do not buy the fraud of so called Green Power? Do we really think charges for normal electricity are not also going up? We have to stop voting for the disaster of steadily wrecking our electricity grid.
