Labor abandons 50% by 2030 renewables target

There were signs from Perth a week ago – then the Illawarra Mercury had a crack at it – then on ABC TV The Drum Episode 15 last night host Ellen Fanning introduced her first segment with “and Labor’s backdown on its renewable energy target”. If anybody sees more on this huge story in the MSM please pass on links. Thanks to Lance for Youtube clip. And here is a longer version on Youtube from Lance on Labor’s inability to keep to their Renewables Target script.

Keep Hazelwood open

Hazelwood 1,600MW of electricity generation is due to close at end of March. This must further stress our already strained power supplies and rack up prices further. People concerned that this would weaken our electricity grid should email politicians asking that Hazelwood be kept open. I will be emailing the PM, Treasurer and several other members of the Commonwealth Parliament. For information email to –
Keep.Hazelwood.Open (the you know what symbol) engineer.com
Terry McCrann had a good article – Keep Hazelwood power station open through takeover

NSW is usually an importer of electricity – interesting that generation for our largest State is propped up by imports from both Qld and Victoria. NSW is an Importer of Electricity – my series of Nemwatch charts annotated with simultaneous demand & price data from AEMO. There will be more data to present on the subject.
The upshot is – Victoria is the Lynchpin State of our grid in terms of electricity generation. Another reason to “Keep Hazelwood open”

Birds igniting on powerlines near wind turbines

Recall my 19 Jan post Tarago fire starts on Capital wind farm – Now the Goulburn Post has “Infigen Energy denies liability for Currandooley fire” The article includes 16 photos in a slide show – number 15 by Mark Dunstone is below – larger version. Other news – Goward pushes for Currandooley coronial inquiry Photo from Goulburn Post. Stop These Things has a post “Wind Power Setting the World on Fire: Infigen Sparks Devastating NSW Bushfire” If anybody has suffered damage there is a comment there from a law firm with an email address.
Above photo is taken from the north – west is to the right and the fire ran east to the left. This map shows the fire outline. and is of course north side up like 99.9% of all maps.
I am puzzled we are not already well aware of elongate clusters of fires along powerlines all across our wide brown land.

Australian Government financial disasters

I will add to this list and links as ideas come in. We may be the lucky country but surely stupidity will extract a price one day. All these issues would make articles in their own right.

[1] AUSSAT $700mill losses & debts rolled over into Pay TV 1990’s,
[2] $6Bn Collins Class Submarines 1990’s – duds we are still stuck with,
[3] Electricity privatisations started in 1990’s – looking at our ballooning power prices would we have been better off keeping the old State Electricity Commissions? Despite the feather-bedded unions.
[4] MRET scheme making 3 worse and harming our electricity grid into the bargain – ongoing multi $Bn’s as taxpayers fund wind & solar that can never power our 24/7 grid,
[5] Defence purchases eg MRH-90 helicopters $4.2Bn,
[6] Frequently delayed and poorly performing F-35 fighters $24Bn alone,
[7] Eastern States Desalination plants ~$20Bn,
[8] Rudd Labor watering down border laws $11.6 billion over five years,
[9] Decades of anti-damism – after not building the Franklin Dam in the 80’s,
[10] Antifracking hysteria affecting gas exploration policy in face of rising prices,
[11] Building the Education Revolution $16.2Bn – More money for Education = worse results,
[12] Adelaide Hospital third most expensive building in the world $2.1Bn,
[13] Inability to control rogue unions like CFMEU which affects 12 and all other construction est +$10Bn,
[14] NBN a future $100Bn mediocre performer?
[15] Buying 12 French submarines before even a prototype is built future $50Bn,
[16] The GST carve up which rewards the basket case States SA & Tas.
[17] Various States and GreenLabor anti-nuclear policies.
[18] Climate change policies – have a effect in 4, 7, 10, multi-$Bn’s.
[19] Just been told about this from Toytown 17 Jan 2017. Amazing construction stuffup with Sydney Metro NorthWest rail bridge.
“Investigation reveals ‘disappointing’ failures in Skytrain construction”

Please send in useful links and analysis. I must have been half asleep to leave the Rudd MkI Pink Batts and School Halls stimulus projects off the list. Also forgot to add GreenLabor’s Murray Darling Basin Plan to waste more dam water to the ocean.

AEMO confusing cause of 28 Sep 2016 South Australian electricity blackout

On the AEMO page “Energy Updates and Media Releases” where you access their various reports post the 28 Sep blackout there is text summarising each link.
The link for – Updated 29 Sep 2016 – Media Statement 3 – South Australia Update 10:30 am – includes the following. “Initial investigations have identified the root cause of the event is likely to be the multiple loss of 275 kilovolt (kV) power lines during severe storm activity in the state.”

However that statement or claim is not found or repeated in the 5 Oct update(current at 3 Oct) see Exec. Summary on pdf page 5/31.
“The weather resulted in multiple transmission system faults. In the short time between 16:16 and 16:18, system faults included the loss of three major 275 kV transmission lines north of Adelaide.” So by 3 Oct the loss of transmission lines was not front and centre as in the statement on 29 Sep.

The 5 Oct AEMO report also has this text in para 3.2 on pdf page 16/31 headed “Network damage resulting from the storm” and mentioning the loss of 22 transmission towers.
“Data currently available to AEMO indicates that the damage to the Davenport – Brinkworth 275 kV or the Port Lincoln – Yadnarie 132 kV lines occurred following the SA Black System.” So towers fell after the blackout!
This statement buried deep in the update also is a backing away from the original “…root cause of the event…” putting blame for the blackout on falling towers.

The next update was on 19 Oct with data current as at 11 Oct.
In this Exec. Summary on pdf pages 5 & 6/31 there is no mention of falling transmission towers. The picture is one of multiple faults where wind farms cut out after not “riding through” voltage disturbances.

In my opinion AEMO should add a dated proviso or addendum to its webpage link text “Updated 29 Sep 2016 – Media Statement 3” – correcting or elaborating on their “…root cause of the event…” statement.
I think Australian taxpayers deserve the most accurate information possible from the experts they pay so well.
