How secure will the South Australian electricity grid be when coal shuts down next month?

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.

Will South Australia walk the talk and close their coal fired electricity generation?

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.

Tasmanian electricity crisis explained day by day

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.

US conducts poll in Australia over Chinese lease of Darwin Port

Just saw this – Adam Giles branded ‘dumb’ for Chinese port deal amid calls for US to explain secret polling – The Turnbull Govt should “man-up” and find a technicality in Commonwealth powers to void this lease and reverse this colossal stupidity. Last November I wrote – Is there a more pointlessly stupid Govt decision than leasing the Port of Darwin for 99 years?

Dimock Water Trial Pennsylvania fracking goes to court – help get the truth out

The FrackNation Facebook page – Ann & Phelim Media LLC – has been attacked by activists leading to two posts being removed and the page being locked for 24 hours. Ann & Phelim are reporting on the Dimock Water Trial in Pennsylvania – Read about it – 7 reasons the trial is shaky – water expert hides – water expert videono proof water contaminated – and like and share every post about the Dimock water trial and then Ann & Phelim need you to forward the links to all your friends so they build up a massive number of supporters for the FrackNation Facebook page. This should help balance the organized attack by anti-fracking activists against the page. If FrackNation don’t fight back – they could succeed in having the page permanently suspended and prevent FrackNation from letting the world know the truth about fracking as the trial enters its final week. – Facebook has sided with the anti-fracking activists.

Tasmanian electricity crisis rolling along

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.

West Australian Treasurer goes all Green talking of shutting down Collie coal fired electricity generation

Coal future at risk for Collie – but how will the backbone of the West Australian electricity grid be propped up? Checkout this great AEMO site for WA with real-time generation graphics. Wind so often contributes little.
Does the WA Govt think they can copy South Australia and shut down coal fired generators? Adelaide can draw on the cable link to Victoria and pull in coal fired electricity to prop up their grid when wind, solar, gas and diesel can not cope. But WA has no “cable to a Victoria”.
The WA Govt idea looks impractical to me without a large expansion of gas fired generators – which are not mentioned in the article. Minister Nahan should check NemWatch at times and see how the various States generators perform.
