Who’s afraid of a cascading blackout?
Last year investment in unreliable and asynchronous generators doubled in Australia thanks to government decree. For some reason, adding another few gigawatts of iffy capricious infrastructure to a 50GW finely-tuned-system appears to put the whole national grid in a near constant state of emergency. The AEMO (our market operator) had to intervene in the South Australian market eight times in 2016/17, but last year they had to do it 101 times.
This warning comes from the Australian Energy Market Commission (AMEC) which makes the rules for the national grid. Why are they baring the dirty renewables laundry? Because the answer to the crisis is always bigger government and this is a reason to call for it.
Renewables stress the grid
Perry Williams, The Australian
Australia’s electricity grid is relying on emergency safety nets to keep the lights on, …
The deterioration of the strength of the electricity network — most pronounced in South Australia — is also spreading to southwest NSW, northwest Victoria and north Queensland, adding to wholesale costs incurred by users.
SA’s electricity system is increasingly operating under the direct intervention of the grid […]
As Australia push-pumps “renewables” into remote locations some of their incomes are suddenly being cut because the losses (as they transmit across long lines) are higher than they expected. On March 8th the AEMO rerated many generators and this year it’s being called a bloodbath for wind and solar. Some of them, like AGL’s Silverton wind farm face losses of 20%.
It all revolves around something called Marginal Loss Factors, a value that is set by the AEMO each year for each generator. The rating is reduced by transmission losses over distance and also by “congestion” from other renewables which are popping up in the same remote locations far from the cities and industries that need the electricity they make. This sudden loss of expected income threatens new wind and solar projects (as it should — hello market signal!) Sometimes the loss factors are hard to predict years in advance which makes it difficult to also predict whether a project will return a profit (even despite the guaranteed subsidies).
Another renewable inefficiency strikes — “marginal loss factors”
Generators are paid according to the electricity that arrives rather than what they produce at the plant. (Seems fair). This is called the […]
Any more free electricity and SA and Victoria will go broke.
In other news a few days ago, the retail price of electricity rose 16% in Victoria and the number of disconnections rose 21%.
In a highly critical report to be released on Tuesday, the Essential Services Commission accused energy retailers of running ineffectual hardship programs that saw customers cut off anyway in most cases. The commission reported power prices leapt 16 per cent last financial year, feeding a 21 per cent jump in the number of disconnections as 60,732 customers had their power cut off. The ESC said the number of disconnections in the last quarter of the financial year was one of the highest on record. — Sydney Morning Herald
Enjoy all the fun of watching our Australian Electricity Market in operation live as tens of millions of dollars get converted into income for AGL, Energy Australia, ENGIE, Origin and Snowy Hydro. No wonder they love renewables.
States with the most cheap wind and solar pay the most for electricity. Graph. AEMO.

No more excuses for sloppy, inaccurate language. How can you run a country with falsehoods?
Hydropower is a generator. Pumped Hydro is giant appliance that sucks electricity and gives you back some later. In a system with reliable baseload generators it is superfluous, redundant, and entirely unnecessary. It is an expense we don’t have to have, didn’t need, and don’t want to pay for. It can only make things more expensive than the system we used to have. Not only do we have to pay for the giant infrastructure, every day it operates we also throw away 20 – 30% of the electrons (so to speak) that go through it.
Scott Morrison says it’s only $1.4 b from the taxpayer, but the total cost may be $4 billion, and as Judith Sloan says, someone’s got to pay — if not through taxes, it will be added to electricity prices. The Snowy Corp may “self fund” it (a deceptively nice way to put it), but they won’t be donating the money.
And the Snowy Corp couldn’t “self-fund” it from electricity bills if they weren’t already so ridiculously high. If we had enough coal power to keep electricity as inexpensive as it […]
A few Australians are just beginning to realize that they are paying for their neighbour’s solar panel. As news spreads, the shine of good-citizen-solar is going to tarnish fast, but it is going to take a concerted campaign to spread the word.
In one corner are 2 million households which have solar PV and thought they paid for it themselves. In the other corner are 7.5 million households which have exorbitant electricity bills. And in every corner and all across the spectrum is mass confusion thanks to the mass media. The fog of advertisements disguised as “news” means if you ask a dumb-enough-question 70% of Australians will say they want the government to set a high RET target to make electricity cheaper. It’s almost like 2 out of 3 people think we need the government to force us to buy cheap stuff, because everyone would buy the “expensive” planet killing volts if we only had the choice. Doh.
That’s $200 per household (and the rest!) added to the electricity bill in 2019
This is just the direct SRES (Small Renewable Energy Scheme) cost. It doesn’t cover the burden of stabilizing the grid, of covering the cost of baseload power […]
Make no mistake, Bill Gates totally believes the climate change scare story but even he can see that renewables are not the answer, it’s not about the cost, it’s the reliability.
He quotes Vaslav (possibly Vaclav Smil?):
Here’s Toyko, 27 million people, you have three days of a cyclone every year. It’s 23GW of electricity for three days. Tell me what battery solution is going sit there and provide that power.
As Gates says: Let’s not jerk around. You’re multiple orders of magnitude — … — That’s nothing, that doesn’t solve the reliability problem.

Australians are the Renewable crash Test Dummies
As I said for free and two months before the ANU, with a 50% annual growth in renewables, Australia is ramping up unreliable power faster than anywhere.
Now comes a paper: Australia: the renewable energy superstar showing that, per capita, Australia is installing unreliable generators in a blitzkrieg pace, more than twice as fast as Germany is, and 4-5 times faster per capita than the EU, USA, Japan and China. No other dummies are even in the race. The largest coal exporter in the world is working harder than anyone to destroy its largest export earner — which would be noble if only there was more to it than being a magical spell to ward off storms.
This is a legendary paper and very helpful. Save the link, copy the reference, send it to your MP, your friends, your newspaper! Why not head to the launch at ANU at 5:30pm, 14th Feb?
Never again can anyone get away with national flagellation for “not doing enough”. Henceforth Green and Labor M.P.’s will stop calling us a national joke, a pariah, and a disgrace. (Though, actually, all those things are true, for the opposite […]
When cheap solar is expensive Badly installed solar PV makes Australia’s grid fragile
On August 25 last year there was nearly a system blackout when, improbably, three states of Australia were islanded by one lightning strike. Within seconds, trips were switching, two smelters were load shed to save the grid from collapse, and across the Eastern Seaboard of Australia frequency and voltages surged or fell everywhere. In Sydney 45,000 homes lost power for a couple of hours. Shops had to close. Trains were stopped. Passengers were stranded. Traffic signals were not working on major roads. There was chaos. Industrial users shut down in a mass of 725MW of load shedding.
The AEMO final report on that day has just come out and shows us just how fragile our grid is. This was not so much a freak accident, as an accident waiting to happen.
It turns out that another cost of cheap rushed solar panels is that many drop out with voltage spikes, suddenly going offline and leaving another hole to fill. The numbers are amazing — of panels installed in the last 2 years as many as one-third in South Australia dropped out when we needed them and […]
South Australians have so much wind power, too much, that in Quarter 3 last year the AEMO had to intervene to cut off excess wind and solar generation. Ever since the Great Blackout of 2016 new rules mean that there must be enough back up power running to cope with the fickle vagaries of intermittent energy. (Obviously, this wasting of sacred green electrons wouldn’t need to happen if people weren’t so persnickety about blackouts!)
This graph is from the Quarter 3 AEMO report for 2018. It is technically about both wind and solar, but it appears to be mostly wind. Solar is not a star player in Q3 because it’s winter.
Would we put up with any other industrial output that had such a dismal performance. Imagine this was your car….
AEMO Quarter 3 report page 7
Synchronous generation is the kind that comes from machines that spin at 50 Hz (like coal, gas, hydro, nukes). These keep the system stable. Happy happy hertz.
But ten percent of all the wind and solar power had to be thrown away in SA because there wasn’t enough reliable back up power to guarantee the stability of the system.

One big government agency quietly admits renewables make electricity more expensive, and another big gov media agency hides it.
The new AMEC report tells us renewables will make electricity prices go down a tiny 2% in the short run but make electricity more expensive in the long run due to forcing out cheap baseload players. What matters most to Australians — that we can expect our electricity costs to be 2% less than “obscene” for the next couple of years, or that the artificial transition we are forcing on the grid will indirectly make electricity more expensive?
Which message does the ABC headline? Say hello to Trivia!
Renewables set to drive down power prices, new AEMC analysis shows The ABC is essentially a taxpayer funded advertising machine for the renewables industry.
A flood of new renewable energy projects is likely to drive down household electricity bills, according to new analysis by government policy adviser the Australian Energy Market Commission (AEMC).
On a national basis, household bills are set to fall by 2.1 per cent — but price falls in the eastern states and South Australia are offset by increases in Western Australia, the Northern Territory and […]
Here’s a problem coal fired plants don’t need to worry about.
Sydney’s ‘catastrophic’ hailstorm happened on Thursday, the damage bill said to top $125 million. How much of that damage is to rooftop Solar PV? The last massive hail storm in Sydney was in 1999 — but there were hardly any solar panels then.
From SBS News
There are wild scenes and images everywhere.
Worst Sydney hailstorm in 20 years declared catastrophic
Jessica Cortis and Sascha O’Sullivan, The Australian
At least 50,000 homes remain without power in northern Sydney and more than 1000 calls for help are waiting to be responded to by State Emergency Services after Sydney and the NSW central coast were yesterday rocked by the worst hailstorms in almost 20 years.
Before anyone yells “Climate Change”, Reader, Pat, found stories about hail the size of Eggs in Sydney in November 1929. Hail the size of Tennis Balls fell on Reids Creek near Brisbane in 1934 and hail the size of Tea Cups fell on Brookville in 1902. Paddington had “ice inches deep” on Nov 1, 1931. There are scores more Hail-the-size-of… Maybe building 2 million solar panels on a continent with […]
Got Solar PV? Don’t let the kids play on the roof
Would you like a 240Volt shock with that?
In Australia, shonky fly-by-night installers are botching the wiring and not screwing the panels on properly. As many as a quarter of solar panels pose a high or severe “electrical safety” risk. Since there are two million households with solar panels, that’s half a million homes sitting under a live problem.
By mismanagement and delusional climate-changing schemes the government has entirely and artificially created the solar bubble. Hopefully people won’t die like they did in the Pink Batts Bubble. Back then, to stop droughts and storms and save the nation from the Global Financial Crisis, the government decided to rush out home insulation. The artificial bubble brought in poorly trained workers and four people died. Kevin Rudd (former PM) now says he wouldn’t have done it if he’d known the risks. But heck, way back in 2010 no one could have realized that artificial government industry bubbles wouldn’t mix well with 240 Volts. Sure.
Australia’s big advance seems to be to stop unnecessary deaths under roofs, and start doing them on top.

It’s Santa’s happy hour in electricity land
Finally, No really, renewables are so cheap we can switch to them and change the global climate for free.
This is a new study by the kind of “independent” group that is totally dependent on Big Gov handouts. It compares Australian prices to other obscenely expensive countries and finds that “renewables push down prices”. Compared to what? Not compared to nations with cheap electricity. And not compared to most of the last thirty years in Australia before we added all the unreliable gear.
The tricky graphs clearly baffled Peter Hannam. If only he were a journalist, he could have asked some hard hitting questions and shown this study to be the concocted vaporous PR exercise that it was.
‘No trilemma’: Study finds increased renewables push down power prices
Peter Hannam, Sydney Morning Herald
Renewable energy drives down wholesale power prices well in excess of subsidy costs and a further expansion of wind and solar would likely push them lower still, a study of Australian and European markets shows.
If renewables actually reduced average prices, this would be a first. Around the world, the more intermittent generators you have, the […]
The Crash Test Dummy accelerates. Australia is steaming ahead in the forced transition to unreliable energy
A lot of the reason for the growth in renewables is the Renewable Energy Target (the RET). Renewables must supply 16% of our electricity in 2018, and even more in 2019.
Strap yourself in. Buried in the AEMO summer readiness plan was the news that our intermittent renewables capacity is forecast to increase by fully 50% this year. All the renewables we had accrued in the two decade “transition” til December last year, we’ve added half again. We are already pushing the bounds of stability and setting price records, but you ain’t seen nothing yet. We are escalating the rate of change.
In toto, we have 56GW of generation of all sorts in the national grid on the east coast. The wind and solar component increased from 4GW at the end of 2017 to over 6GW by the end of 2018. But it doesn’t take much intermittent power to change the way the whole grid works.
Things are so fragile that a few weeks ago, when 240MW of reliable supply was suddenly not available for this summer, the AEMO had to issue a […]

There’ll be blackouts this summer if nothing is done, AEMO report warns
Stephanie Dalzell, ABC News
Victoria and South Australia are at a high risk of forced blackouts this summer if no action is taken, according to the latest report by the Australian Energy Market Operator (AEMO).
Not enough supply? Put another million bucks on the BBQ:
To stop that from occurring, the AEMO has sourced emergency energy reserves, which are typically not available to the market and are only accessed when supply is not keeping up with demand.
Those emergency reserves — otherwise known as Reliability and Emergency Reserve Trader (RERT) resources — do not come cheap.
It’s only money:
The report stated that last summer emergency energy cost taxpayers in Victoria and South Australia almost $52 million.
That equated to an average of an extra $6 per household bill.
That’s nothing. The two day heatwave […]
Some days I wonder if I should spread stories that make us sound like a recidivist third-world backwater struggling to maintain our voltage. But the ABC is already smashing away.
Just when you think there couldn’t possibly be another drawback to solar panels, lo! Solar Panels are pushing up the voltage at midday often as high as 253 Volts when it supposed to be more like 230 to 240V. This means appliances are using more electricity, that makes bills even higher. It may also be breaking appliances (making other bills go higher too). We’re not really sure about that, but when that study is done, it’ll already be 1.8 million panels too late.
Non-solar users are paying for this surge (and the appliances) — for every 1% increase in voltage, the costs go up 0.7%. Then, to ice that gravy-cake, the inverters on solar panels are also shutting off at 253V, meaning that poor home owners who paid thousands are not generating power for the grid. All up, solar is bad for you, bad for them, bad for our light-globes.
The warning comes from groups running the electricity networks in Australia.

It’s not often we see a report that turns things on their head quite like this.
Wind turbines may cause more local warming than global cooling in the next century.
Photo: Jo Nova
If the US were to install a lot of turbines, Wind power could warm the United States by 0.24 degrees Celsius instead of cooling it, because wind turbines “redistribute heat” in the atmosphere. They mix the surface layers. (0.24C would be equivalent to two decades of recent warming.) The largest effect is at night where wind plants can warm the local area by 1.5C.
At least 10 previous studies have now observed local warming caused by US wind farms. Keith and Miller compared their simulated warming to observations and found rough consistency between the data and model.
Nick Carne — Cosmos magazine
The new studies by Keith and Miller were published in Environmental Research Letters and Joule.
Major downer. The power density of wind energy is up to *100 times* less than predicted.
The new research suggests we can’t put too many turbines to close together or the whole group become far less efficient. That means we need 5 – […]
Green genius: Pay $1400 a year to not stop any storms
Finally some veteran engineers checked the Labor Party 50% renewable plan and the AEMO “65% scenarios”. Unlike others, their study that did not involve magical assumptions that the cost of renewables would dramatically fall. Instead they used “actual costs” and found the price of electricity will rise “84%” and cheap coal power will be forced out of business (just like what we also found here). The engineers include Barry Murphy, former managing director and chairman of Caltex. Robert Barr, an electrical engineer and academic at University of Wollongong. If only Kevin Rudd had asked them in 2007.
Engineers warn of bill shock under green energy surge
Adam Creighton, Economics Editor, The Australian
Electricity bills will soar and gas and coal-fired power stations will close if the share of wind and solar generation increases dramatically, engineers have warned after analysing the nation’s energy supply.
It found bills were likely to soar 84 per cent, or about $1400 a year, for the typical household, if wind and solar power supplied 55 per cent of the national electricity market.
A quarter of Australian rooftops have solar, […]
The world still runs on coal and oil
After 20 years of subsidies, intermittent renewables account for just 3.6% of total energy generation. That’s the tiny purple sliver in the graph. Global power means not just electricity, but also fuel used in transport. And this is where wind and solar power are respectively old and slow, or modern but useless.
Someday solar powered planes might make their first round world trip in 48 hours but at the moment they need 16 months. There’s a a bit of hitch in the global energy transition.
Hello fossil wonder fuels:
Global Primary Energy, Graph, 1965-2018
Intermittent renewables are pretty useless everywhere:
Global Primary Energy, Graph, 1965-2018
Solar energy might have “made waves” and increased by an astounding 100GW last year, but it’s still irrelevant:
Oil remains the world’s dominant fuel, making up just over a third of all energy consumed. In 2017 oil’s market share declined slightly, following two years of growth. Coal’s market share fell to 27.6%, the lowest level since 2004. Natural gas accounted for a record 23.4% of global primary energy consumption, while renewable power hit a new high of 3.6%.

The advantage of communist autocrats is that they can create government havoc so much more efficiently.
The Chinese solar boom was so big it became the world’s largest solar market. It was so big it pushed up global “clean energy” investment to a record high. China became the veritable show pony of the solar spruikers: “leading the world in clean energy investment”. Mashable tells us it was so big “the solar boom could be seen from space“.
But the star advertisement for renewable glory was all based on subsidies:
The Chinese solar boom was “pretty significant”
A couple of months ago the Chinese government admitted they were cutting the subsidies to make electricity cheaper again for consumers. That hit the stock market. Now projects are being cancelled and orders are drying up for the hapless manufacturers.
The free market might be telling us something China’s solar industry is at a crossroads
“Without subsidies there’s no return on investment for over a decade, so investors and property owners aren’t interested in distributed solar. With subsidies it only takes seven years to recoup the investment,” he adds.
China’s solar manufacturers are unhappy with recent government policy changes […]
