Title: Tesla Batteries starting to do good in SA

Tesla’s plan to deploy 50,000 Powerwalls in Australia in order to create a giant virtual power plant is moving forward with 1,000 more homes as part of the second phase.

The project is the biggest of its kind and it would dwarf any other stationary energy storage deployment if it is ever completed.
It came around after Elon Musk visited South Australia following the launch of its giant battery system in the state.
Musk gave an interview during which he was informed of the significant hardship that Australia’s high electricity prices are putting on families.
Visibly affected by the issue, Musk vowed that Tesla would “work harder” to help solve the problem.
A few months later, Tesla announced that it reached a deal with the South Australian government to install solar arrays and Powerwalls on up to 50,000 homes.
The deal was jeopardized after a new government was elected in the state a few weeks later, but they have since come around and confirmed that they will be moving forward with Tesla’s initiative as long as it is financed successfully.
In July, Tesla deployed the first 100 Powerwalls with solar for the new virtual power plant and focus on reducing the cost of electricity for low-income households.
It is already having a great impact for the families. Local news featured a public housing tenant in Adelaide who was spending over $500 every quarter for electricity and she has now seen her bill reduced to $175 since the installation of the system.
Now the government announced that they are moving forward with the “second phase”, which includes 1,000 homes.
Minister van Holst Pellekaan said:
“The VPP will deliver cheaper electricity to some of South Australia’s most disadvantaged households whilst increasing the reliability of the state’s electricity network,”
They have also announced Energy Locals as a new retail partner in the project to help Tesla and the government deploy the systems.
The 1,000 homes that will be part of the second phase of the VPP still need to be SA Housing Trust properties to facilitate the direct impact for low-income families.
With the upcoming third phase, they say that they will open up the process to other South Australian households.

That will be 1100 low income families wont be paying through the roof for electricity.... Good to see ;)

What is the cost?

What if the proposed batteries are a gigantic fail and that only becomes truly apparent after all the fossil fuelled generators are mothballed?

Then of course that only leaves a touch over 700,000 households with no backup. ;)

So, the story so far, we have warmed by about 1C since after the industrial revolution, apparently. Though the data is sparse until after 1950 especially in the Southern Hemisphere. And with no remarkable adverse effects so far. But it is that extra 0.5C that is gunna do it? ;D ;D ;D ;D ;D ;D

Apart from that we are all gunna die. We are not immortal. As a species those that don't adapt also die.

You obviously didn't read the scientific papers I posted. But that is not unusual.

You just fail to see any science. So tell us what type of smoothing they used in compressing 400,000 years into 6 inches? How much data was lost?

You know the problem with CO2 and firn?

"We estimate the permeation coefficient for CO2 in ice is ∼4 × 10−21 mol m−1 s−1 Pa−1 at −23°C in the top 287 m (corresponding to 2.74 kyr). Smoothing of the CO2 record by diffusion at this depth/age is one or two orders of magnitude smaller than the smoothing in the firn. However, simulations for depths of ∼930–950 m (∼60–70 kyr) indicate that smoothing of the CO2 record by diffusion in deep ice is comparable to smoothing in the firn. Other types of diffusion (e.g. via liquid in ice grain boundaries or veins) may also be important but their influence has not been quantified."

https://www.cambridge.org/core/journals/journal-of-glaciology/article/co2-diffusion-in-polar-ice-observations-from-naturally-formed-co2-spikes-in-the-siple-dome-antarctica-ice-core/8C8638D9EC90AEA53B90B3DE70E594C0

And then of course there was the other one -

"Since 1812, the CO2 concentration in northern hemispheric air has fluctuated exhibiting three high level maxima around 1825, 1857 and 1942 the latter showing more than 400 ppm."

https://journals.sagepub.com/doi/abs/10.1260/095830507780682147

400ppm and only 70 years before it was recorded by Keeling. ;)

On that inevitable day when all the batteries blow up, the solar panels get too dusty, and everyone in the Riverland goes mad from wind turbine syndrome, we'll have to go and take the mothballs out of the turbines at the gas plants, although one has to wonder why moths would be a problem for machines that are not made of tasty linens.

1. The graph is as simple as can be so you can read it. But don't look at anything else; you might, just might learn something.

2. You do understand modern readings can neither confirm or deny paleo data?

SA hasn't got a battery for that. It's just a little battery that provides cheap FCAS and keeps SA's lights on for a bit when normal supply trips.

So if the battery is to be tapped to prevent load shedding it must be dual purpose.

If it is dual purpose it will apparently run 30,000 homes for  about 1 hour. Or because SA has about 767,500 households for about 3 minutes, providing shops and industry are isolated from the grid.

The diesel backup generators will have to be run up to temperature and speed before being switched over to the grid. They will also have to be phased into the grid. If they are fed in out of phase the generators will try to run as motors and cause widespread blackout and blown up generators.

It's not meant to power the entire state by itself. It just adds a bit of extra juice and frequency control when, for example, the Heywood interconnector trips, and buys time for local generators to come online. It's already saved the state from a couple of blackouts.

Renewables-rich South Australia became a net electricity exporter for first time;

• 12 new wind and solar farms totalling 1050MW of capacity were added to the grid, including 500MW of large-scale solar, trebling the amount of large-scale solar in the system;

• The continued rapid uptake of rooftop solar by homes and businesses kept a lid on grid demand, even if overall consumption showed a rise, and;

• Electricity generation emissions in the national market fell again, but only slightly.



The most surprising of those developments may be the South Australia achievement, which shows that since the closure of the Hazelwood brown coal generator in Victoria in March 2017, South Australia has become a net exporter of electricity, in net annualised terms.

Hugh Saddler, lead author of the study, notes that this is a big change for South Australia, which in 1999 and 2000, when it had only gas and local coal, used to import 30% of its electricity demand.

The fact that wholesale prices in South Australia were higher in other states – then, as they are now – has nothing to with wind and solar, but the fact that it has no low-cost conventional source and a peaky demand profile (then and now).

“The difference today is that the state is now taking advantage of its abundant resources of wind and solar radiation, and the new technologies which have made them the lowest cost sources of new generation, to supply much of its electricity requirements,” Saddler writes.

Now the fact that SA has over 767,000 households comes from this-

"The Census usual resident population of South Australia in 2016 was 1,676,653, living in 767,267 dwellings with an average household size of 2.39."

Oops, it was just the one time: 25 August 2018 when the Heywood interconnector failed. The frequency surge should have caused blackouts in SA but the battery provided instant frequency control.



You sure about that time line?

You know, the one you're "merely quoting".


You seem confused. That article I quoted said -

If "supply runs low", not "supply disappears entirely leaving the battery to power over 767,000 households".

I see. So you fabricated some nonsense about the battery supplying the entire state for three seconds.

So much for "merely quoting the ABC".

For 2 seconds maybe.

"The battery can't power the whole state by itself, therefore it's a white elephant."

How does supply "run low"? Supply gets over drawn. That is too much current is drawn. Load shedding is the reduction of load on the grid. The only ways to reduce load on the grid are to cut connections. Hopefully hospitals last, then households, then business.

Not at all. The Tesla is supposed to be able to power 30,000 homes for about 1 hour. I will let you do the maths.

Link, from SA Power Networks I hope.


LOL. Not only does the forum prevent me from posting links, the idea that SA Power Networks has this info on their website is laughable.

This is the only link mentioning Heywood about the 28 August.

"This next graph shows the confidence that the battery can provide the market operator going forward. The modelling done by Aurecon looks at what might happen if the Heywood inter-connector – the main link from Victoria and South Australia – were to trip with 200MW of imports."

https://reneweconomy.com.au/deep-dive-into-first-year-of-tesla-big-battery-at-hornsdale-93479/

dated 25Aug 2018

But there was this -

"Queensland and South Australia were exporting power across the interconnectors when they were simultaneously tripped on Saturday, forcing power to be cut to big industrial users and retail customers in NSW and Victoria."

https://stopthesethings.com/2018/09/03/blackout-nation-chaotic-delivery-of-wind-solar-causing-blackouts-wrecking-australias-power-grid/

The batteries would not be exporting power.

See the AEMO's Preliminary Report: Queensland and South Australia system separation on 25 August 2018.

The QLD separation actually caused the frequency drop in SA, VIC and NSW. This caused load shedding (and blackouts) in NSW and Vic, but not SA because the battery provided instantaneous FCAS. SA was then islanded, which would have caused generation shedding (and blackouts) in SA except that the battery was able to immediately add load by charging.

Apologies to the OP for derailing a thread about the virtual power plant by bringing up the Hornsdale battery.

" add load by charging"? Charging is a drain on the system.

To add load would imply an overproduction of power and the battery was needed to load the grid down to prevent oversupply.

So the battery didn't provide any power in SA it was used simply as a DC choke. ;)

So tell us how if the grid gets overloaded due to too many air conditioners how long will the battery last?

Where did you get that piece of schlock? Every bit of energy used has the potential to overload the grid.

"This summer you could get paid for turning off your air-conditioners under a new trial scheme floated by federal government to prevent blackouts.

In a bid to prevent blackouts amidst worsening energy crisis, the federal government has launched a new trial program where households and businesses across three states in Australia will be paid to turn off their air conditioning."

Why would it be embarrassing for me? The worsening energy crisis is due to to the closure of Hazelwood power station thus placing more reliance on intermittents. The greenies should be embarrassed, but they won't be.
