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 will [...]

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 [...]

SA renewable electricity market mayhem as frequency stabilizing costs hit record breaking $90 million

Since SA was islanded the costs just to keep the frequency stable are as much as the energy itself

Two weeks ago the Australian grid had a major near miss, and South Australia has been isolated from the rest of the nation ever since. It was supposed to be connected again in two weeks, but repairs to the 6 high voltage towers that fell over, evidently will be longer. Strangely, apparently no news outlet has mentioned this in the last two weeks.

While SA has been the renewables star of the world for two weeks, there’s been mayhem in the market. Instead of cheap electricity with 50% renewables it’s chaos. Allan O’Neill explains that the cost of stabilizing the grid has gone through the roof. It’s so bad, and generators have to contribute to balance their output, that solar and wind power are holding back from supply because they can’t afford to pay the costs to cover their share of frequency stability.

But when South Australia became islanded by the transmission line collapse, FCAS requirements for that region could only be supplied from local providers – and there is only a small subset of participants in South Australia [...]

What do we call it when the State turns off your air conditioner? A “Peaksmart” moment

You can’t make this stuff up.

The Government advertising bureau — the ABC — is telling Queenslanders that it’s good for them if the government switches off their air conditioning. As we pay more than ever for electricity, we also lose control of even our household appliances. If we get something back for the overpriced service, the propaganda unit calls this a payment, and a benefit. If you have a Christmas party and 30 guests and you can’t use your own air conditioner, don’t forget, the State knows best. If it causes “whitenoise” interference, adds one more failure point, or causes people to turn their air conditioners down in temperature preemptively, or program them to come on earlier, who cares?

If the ABC says something is smart, we know it’s …

Power companies will soon be paying you to cut your energy use

Stephen Long, ABC

The units installed on the walls of his apartment look the same as any other air conditioners, but there is a difference. They’re fitted with “PeakSmart” technology. It allows the electricity network company to send a signal that turns the air conditioning down for a [...]
