It’s a grid on the edge
Like a meteor-shower, the dinner time performance today may or may not be a spectator event. The fun may start at 4:30pm in Qld, NSW, Vic, SA and Tasmania — a full quinfecta at $15,000 per MW/h. The first wave of winter cold is about to wash over the grid, and those solar panels will fail just as people plug in their heaters, ovens, dryers and kettles and there is a four hour spike at $15,000MWh forecast. The graph below is the forecast for NSW, but it is essentially the same tsunami shape and dimension in every single state of the National Energy Market. Right now I presume there are engineers in the control rooms sweating over alternatives and they may well pull it off. These wildly high spikes have a way of resolving at the last minute. But think for a moment what kind of stakes we’re playing with. Hypothetically, if there was a 12,000MW demand for 4 hours in NSW at $15,000, that’s $720 million dollars worth of electricity. A few days like that would pay for a new coal plant, but no one seems to be listening to that price signal…
[…]
It’s the day before the election and all through the house, electricity bills are doubling…
The price rises are so extraordinary one retailer is asking their customers to leave “in the next 24 hours”.
Across Australia small power suppliers are sending emails to customers right now warning them that their rates are going up next week by eye-watering amounts. Wholesale electricity prices were at a record high in April this year, and it hasn’t improved in May. Prices are hitting $200-$300 per megawatt hour, not as a peak, but as a 24 hour average. In South Australia two days ago, the average for the full day was $1,141. Futures contracts are rapidly taking off and these rises are starting to flow through to customers. Already, the small retailers are bleeding cash, just as they did in the UK, and if wholesale prices don’t come back to Earth soon, they will go out of business.
Reader Brett in South Australia shared an email from Discover Energy. As of next week the standard peak rate will rise from 39 cent per kilowatt hour to 70 cents. Off peak rates rise from 27 to 46. He also adds, “My brother lives in NSW […]
Generation tonight….
Just another week in the Transition we (Don’t) have to have
With 65 Glorious Gigawatts the Australian grid system has a vast excess (theoretically) of generation capacity, yet it’s so fragile that the loss of an interconnector, normal maintenance and a few coal turbines down — has triggered $100 million dollar price spikes. These burning pyres of money are so savage the average cost of wholesale electricity — across a whole day — is lately in the realm of $200- $700 per megawatt hour over most states for 24 hour periods. For the last week, daily prices have been ten times the “old normal”.
And it comes on the back of the most expensive April in the Australian grid history in every mainland state on the National Electricity Market.
Autumn and spring are supposed to be easy days in Australia with peak demand only running at 27,000 MW. Because things are lighter, generators do normal maintenance at this time of year, but at the moment, there doesn’t seem to be any room for that in the network. In summer, demand is often 5,000MW higher. Where’s that going to come from?
Factories are shutting down for fear […]
Mike Cannon-Brookes might be an Australian tech-billionaire who wants to buy out one of our biggest energy companies and get rid of coal, but not only does he apparently not understand electricity grids, he doesn’t even know what a free market is.
In a free market customers could choose not to buy green electrons:
If we had a real free market in energy, we could a tick-that-box on our plan that said “100% coal fired, cheapest available reliable electricity”. Instead, all Australians are forced to buy electricity from a hobbled patchwork grid which has been repurposed as a Global Air Conditioner.
It’s a national grid crafted through “Renewable Energy Targets”, and pure hopium. Hidden in our electricity bills, taxes, and frozen-pea packets at Coles, are multiple subsidies to help wind and solar power. Poor Australians have paid to help put discounted solar panels on their rich neighbors roofs, and are paying for back up, storage, stabilizers, unnecessary two-billion dollar interstate transmission lines, and demand management plans.
Every windless minute at night the poor pay more for electricity than they would have — if the Agents of Weather-changing Sorcery were not allowed to romp freely through the energy market. Once […]
Tuesday was a wild day for Queensland Electricity. An explosion struck the Callide C Power Plant triggering a cascade of other plants to switch off within seconds. The massive 2.5GW fall in supply took the grid frequency in Brisbane to a hair raising 49.55Hz. How close did it come to falling over? Half a million people lost power for a couple of hours but a Statewide blackout was averted. Luckily no one was hurt.
Meanwhile the people in power were not saying “Hydrogen”, or “explosion” but the Supercritical Units at Callide are cooled with hydrogen, and there was an explosion. The owner CS Energy called it just “a fire”. But in other news reports people in the nearest town said it was “the loudest explosion they have ever heard”.
Hydrogen, it seems, is used in some coal plants as a coolant, but Holy Hindenberg, it is known to explode. (See Ohio in 2007, Pittsburg in 2017 and India, 2019) . A Union official said it appeared the hydrogen filled generator of the main turbine had suffered a catastrophic failure. And it’s all exquisitely awkward, as David Archibald points out, happening while a two day Hydrogen Conference is on — as […]
The island of Jersey gets 95% of its electricity via cables from France. The latest post-Brexit fishing dispute got so hot so fast, that a French minister even suggested cutting off the electricity if they didn’t get their way. 60 French fishing vessels were protesting at slow licensing. But naval ships from both sides were even called in to patrol the area, the situation has been defused.
Surely the UK government must be working out that electricity supply is a major tool for foreign disputes. Currently about 10% of the UK electricity comes in via undersea cables*, but that is set to rise to 25%, according to the Daily Mail. Surely alarms are ringing? This is not even the first time this outrageous threat was made. Macron himself threatened it last October too. See “Hands Up! Your money or your Fish!“
There is a very uneasy power balance here: The right to fish in British waters is worth about 650 million euros to EU fishermen, but European energy markets were worth up to £2.3 billion for the UK.
Not only does it leave the UK in a weaker negotiation position, but a selfish foreign player could also ambiguously twist […]

Texas toyed with cascading crises
The Green Experiment could have gone so much worse. Here’s a man who was a gas industry executive involved in a near miss in New England in 1989. The four day blackout sounds bad, but it was a lottery win compared to the worst case scenarios. Not only was a full state-wide blackout possible, which may take months to correct, but the gas system is a bomb waiting to go off too.
ERCOT officials admit they only just averted a blackstart:
Texas was “seconds and minutes” away Texas’ power grid was “seconds and minutes” away from a catastrophic failure that could have left Texans in the dark for months, officials with the entity that operates the grid said Thursday.
— by Erin Douglas, Texas Tribune
The Blackstart in Venezuela took weeks to restart — rebooting an induction motor takes six times the normal current. Energizing a substation can cause explosions. It’s much easier to add load to an operating grid than to rebuild one from scratch. Surges on start up can break things, that fail. It can take rolling rounds […]
Even if the Texas situation resolves tomorrow the anger will burn for months
A few hours ago, about one quarter of Texas still didn’t have power. After three or four days without power some houses are so cold the fishtanks have frozen over. Some people have been without power for 84 hours straight and ERCOT — the Texas Electricity management can’t say when it will be restored (though they have just announced it might be soon). It is still operating under the EEA 3 highest emergency level. Many people have had their power return for a couple of hours only to lose it again. And there is a burning anger at the unfairness of it all. People say they can see houses, shops and office buildings “lit up like Christmas trees” but have had no power themselves for days. Some are using their cars to warm themselves and charge phones but after three days they are running out of gas. There are restaurants that are offering free food.

Things are still not looking good in Texas.
At the peak demand on Sunday in Texas the people were using 70 Gigawatts of electricity — an all time record. Then both wind and gas generators failed. Currently the ERCOT Grid is using about 42GW of electricity and ERCOT reports of up to 46 GW of generators being out of action. Total wind output is still under 3GW out of 30GW* of wind capacity.
The gas was the back up to the Wind, but Wind power can’t be a back up to the gas (or anything else).
An ERCOT press release claims that they still have to loadshed 14,000MW which means 2.8 million homes.
“As of 9 a.m., approximately 46,000 MW of generation has been forced off the system during this extreme winter weather event. Of that, 28,000 MW is thermal and 18,000 MW is wind and solar.”
It’s not clear to me how they arrive at only 18,000 MW missing of wind and solar. Perhaps they are only counting the 6 or so GW they expected to be able to use of windpower?
There is so little power that the electricity companies can’t even rotate the blackouts between […]
Welcome to Woke World where states pretend to control the weather while the weather controls the state
An Arctic blast; an ice storm called Uri, has frozen up half the wind turbines in the hot southerly Big State of Texas.
Supplier Oncor is warning it may be hours before power is restored. People are livid, their pipes are freezing, some have had no electricity for 12 hours. Their website is down, their phone lines are out. People can’t even report outages.
UPDATE: NY Times is already blaming Climate Change for the frigid weather.
While the wind turbines have been working at only 3 – 10% capacity in Texas. Gas wellheads have frozen so there are gas shortages as well. Details at the end below.

The UK wants to get back its fishing rights as part of a Brexit deal. The French aren’t too happy about that, but since the UK is heavily dependent on French interconnectors Macron can and is holding the UK electricity grid hostage.
Green Energy puts the UK in a much weaker negotiation position.
The French interconnectors under the Channel are needed both to import reliable nuclear power and to sell off the excess fluffy green kind of unreliable electricity that UK wind power makes at random times. The “value” of energy sales is more than the value of the fisheries (at least in hard currency). But UK imports are larger than the exports, and the UK electricity grid is so fragile it fell over last year leaving people stuck in underground trains for hours, and cutting off a million customers in an instant. The biggest weakness of all is probably the reliance on a foreign power to just keep the lights on. The cost of unplanned blackouts would trump everything else. And could the French “Break” the UK grid with plausible deniability and some inconvenient outage? Sorry but the interconnector had a fault?
I know they might not play that […]
It’s another hidden subsidy for “Green Power”.
Big-Bandaid: Unreliable generators need thousands of kilometers of extra transmission lines.
The totally non-essential new interconnector between NSW and SA will now cost nearly a billion more than was expected. It will add no new baseload generation but allow the random energy surges from South Australia to interfere with New South Wales supply. Surges of subsidized energy will break the balance sheets of cheap baseload infrastructure in NSW, making them less profitable, and driving them out of business unless they charge more for the fewer hours they operate. Both states will spend more on electricity but be less self sufficient, and more dependent on other states.
Why aren’t NSW generators complaining? Because they know prices will rise, not fall. Ask AGL — the more coal plants it can close, the more profits it can make from the gas and unreliable generators.
The extra interconnector won’t solve the real issues — it “probably” won’t change the massive high pressure weather systems that stop wind towers working in both states simultaneously. The magical transmission lines “probably” won’t stop the sun setting in Adelaide one hour after it sets in Sydney either. But it […]
Australians used to have an electricity grid that gave them the freedom to work from home
For years they told us to work at home to help the environment. But thanks to a decentralized unreliable grid, Australians are now being warned that it will be a “disaster” for the grid if they stay home and work with their air conditioner on in summer.
Now we better drive to work so the solar-windy-grid doesn’t fall over:
Why working from home could be a disaster for Australia’s electricity grid this summer
Emma Elsworthy, ABC
Air conditioners could send Australia’s power grid into meltdown this summer, as roughly one third of the workforce do their jobs from home, experts have warned.
According to research company Roy Morgan, more than 4.3 million Australians are working from home…
But warmer weather has come with a warning that increased use of air-conditioning in homes could lead to more blackouts and higher electricity bills.
“Air-conditioning is what drives our maximum demand in Australia,” said Peter Dobney, the former founding chairman of the Energy Users Association of Australia.
“We can expect higher prices, in fact, I […]

Why do so few see the enormous subsidy cost of keeping the South Australian electricity experiment alive?
Having got too much intermittent, unreliable electricity, the state is still in danger of another statewide blackout. One third of the solar panels on homes are being switched off automatically because the electricity they provide is not just useless, but dangerous. What the state needs is baseload power, but the solution we’re told is to spend another incredible $1.5billion dollars on an interconnector with NSW, presumably so SA gets a lifeline to the reliable coal power in Queensland.
That’s a $1,500,000,000 repair bill for an unreliable system that cost a fortune to build, but is unsustainable without a giant bandaid.
Price rises coming in NSW and QLD:
As more unreliable generation and random green electrons infect the NSW and Qld grids, their cheap baseload providers will also find it harder to compete. The increased downtime will chew out some of their profit margins, but their costs will be almost the same. So, as sure as the sun rises, they will have to […]
Another hidden renewables tax buried in complexity
Here in Renewables World we now have to pay companies to make less of the products we want. It’s a sign of how fragile and dysfunctional the Australian grid is.
“Big energy users like factories and farms will be able to earn money by saving energy during heatwaves and at other times when electricity prices are high,” the Australia Institute’s energy lead Dan Cass said.
They call it “wholesale demand response”. We call it planned blackouts. All over the country equipment will be switched off when its needed most so that our green grid doesn’t fall over, or create billion dollar price spikes.
With some of the most expensive electricity in the world, there is already a strong price signal driving companies to use electricity efficiently. This new “price signal” drives them to be less efficient. Because the grid is now incapable of providing regular reliable electricity whenever it’s most useful to companies, the government is adding a whole new layer of complexity to try to squeeze out the spikes they can’t handle.
This move will mean more people will have to be employed in account-management, but the products made will […]
Welcome to the new complexified energy grid where a cloud can cause a system black event — knocking out power for as much as nine hours. This affected the hospital for 30 minutes and the prolonged problems caused many businesses and supermarkets to close. Alice Springs is an island microgrid servicing about 29,000 people in the centre of Australia. It was 38 degrees C yesterday when the power went out. Shame about those fridges and air conditioning units.
Alice Springs is a mini version of larger grids showing how fragile these new complicated systems of multiple generators based on weather events and batteries can be.

Guess which state, big business will be headed to next?
Brilliant! Let’s talk about a Quexit of the NEM. Nationals MP, Keith Pitt is suggesting that Queenslanders could cut their power bills if Queensland stands alone and disconnects from the rest of the Australian National Grid. There are concerns from experts within the energy sector that this could result in blackouts in other states… (is there an “e” in electricity?).
Keith Pitt says these are Queensland assets paid by the Queensland people, owned by the Queensland people, but we can’t continue to prop up states that make silly decisions. He’s driven by one motivator, and that’s price for consumers.
Check out the AEMO data dashboard. On any given minute Queensland is probably sending electricity to most of the NEM.

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 […]
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.
