Clean Energy Council delusional about wind power

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.

Moratorium required on further Australian wind power

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

Coast to gorgeous coast – Australia has only 200MW wind power at 8am

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.

The Australian Energy Market Commission makes it up as it goes along

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.

South Australia burning diesel to prop up electricity exports to Victoria

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 Sliding-scale agencies can help people get proper bulk viagra psychiatric evaluations.

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.

Australian electricity bills set to soar

Our electricity grids are clearly under stress as evidenced by these booming AEMO daily average prices. On 6 June I blogged – Surge in wholesale electricity prices last week – and I expected the daily average AEMO prices for the four States would return to be mostly under $50 again. Not so, the South Australian price is trending over $100 and the three big States are near $100 on the 30 day average.
Eventually these booming power prices will feed into power bills and the media is ignoring the issue. NemWatch is worth checking to see which State is generating from what source at any point in time.

Remember the Port Augusta coal fired stations shut on 9 May – so SA price increases in May & June not that odd as supply tightened. But why do the three large States with ample coal generation also show major RRP increases in May and June?

Tasmanian power exports via Basslink in Dec 2015 were triggered by Victorian price signals

I should have included this price graphic in my March blog – Tasmanian electricity crisis explained day by day
Now it is crystal clear to see that Tasmania initiated power exports when the Victorian RRP rose through ~$80(per MWhr) and exports ceased when Vic RRP fell back. Looking at my March chart of the 5 minute data from 15th to 21st Dec 2015 it is clear that imports ceased just prior to exports being commenced and vice versa. I have no idea what stresses can be induced in a cable when the current is reversed frequently like this. It is also worth noting that the export MW exceeded the import MW. Here is the daily chart from 1 Nov 2015 to 10 Mar 2016.

Rival thermal solar power plants proposed for Port Augusta

Taxpayers should be watching their hip pockets. Concentrated Solar (CS) proposals for the Port Augusta region have made news for a while now – this technology involves the use of tracking mirrors to concentrate the suns rays to heat a container of liquid which can then be used to generate electricity when the sun is not shining. Solastor announced a plan to build a 170-megawatt “graphite block heating water” solar thermal plant. Then we hear about the US firm Solar Reserve who have a 110MW molten salt CS plant at Crescent Dunes in Nevada which has cost +$Bill and they claim produces 500K MWhrs per year which is less than Queensland produces from Hydro.
The Port Augusta future solar power scene is made more interesting by the Solarstor Chairperson Dr John Hewson going on the attack against Solar Reserve – and then the RenewEconomy site criticising Dr Hewson. Marvellous stuff as the GreenLeft pixies brawl – considering the way renewables advocates always stick so close to the hard provable facts. Sadly, a huge part of males suffer from different sexual problems and erectile dysfunction always tops the list. This drug may make you order generic viagra feel drowsy or sleepy. Acai berries are exceedingly nutritious and helpful foods that can help you, but you may have to do a little research to find reliable source. All of viagra from india thought about that Ajanta Pharma products can safely ordered through registered pharmaceutical store. I have found it near impossible tracking down reliable evidence for claims made by solar proponents. More later – for over five years now Solarstor has been building/experimenting with a CS pilot plant at Cooma using a graphite block on a tower. There is also a Solastor installation of eight towers(graphite blocks) and mirror arrays at Lake Cargelligo in central NSW. Near Forbes Vast Solar is building a molten salt thermal solar plant. As I said – more later on the NSW thermal solar plants.

Exactly why wind power is too often useless

After posting the submission by Tony from Oz re Queensland Govt plans for 50% renewables by 2030 – I wondered what NemWatch shows now. The chart below shows next to zero effective wind across Tasmania, South Australia, Victoria and New South Wales.

So in our future renewables nirvana what would we do at times like now? Turn off most of Australia and all just sit around waiting for wind. Or do we keep sufficient fossil fuel powered generators waiting around to substitute for wind when required? Who pays for that? We will pay have no doubt. Vote 1ALA and always put Greens last.
