Extension cord to rescue renewable South Australia will now cost $2.4 billion

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 […]

Thanks to wind and solar power, Australians have to drive to work to save the planet

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 […]

SA: Still at risk of blackout, one third of solar PV “switching off” to save state, needs $1.5b interconnector bandaid to NSW

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 […]

Desperate signs: Australian companies will be paid to use less electricity

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 […]

Oopsie solar-battery fail? Cloud causes System Black event at Alice Springs affecting thousands

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.

Yesterday: Thousands impacted by Alice Springs power blackout*

Steve Vivian, ABC News

Thousands of residents in Central Australia went without power yesterday afternoon, with some experiencing blackout conditions for up to nine hours.

Electricity was cut across the Alice Springs region around 2:30pm yesterday and was not restored in some areas until 10:47pm.

Australian grid wars: MP says Queensland should cut off other states to make electricity cheaper

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.

Renewables stress: The daily battle just to keep the lights on in Australia

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 […]

“Market Bloodbath”: Too many new remote renewables projects means high losses

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 […]

Gates on renewables: How would Tokyo survive a 3 day typhoon with unreliable energy?

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: destroying their grid faster than any country on Earth

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 […]
