Coober Pedy Hybrid Renewable Power
By Jo Nova
This is the feasibility study for the whole country that the government could have done…
Instead of doing reckless experiments with our national grid, we could have done a practice run and transitioned one small town to see if it worked. If renewables were going to be successful anywhere, it would be in a place like Coober Pedy. After all, these small desert communities have wide open spaces, lots of sun, and new renewables only have to compete with expensive diesel generators, not cheap coal.
Fans of renewables were partying last week because one small town had managed to run for “nearly five days” on renewables. Nearly five!?
You might think this was a new set up, but this is a system that was built in 2017. Basically, the people of Coober Pedy have been waiting for nine long years to get this lucky with the weather.
And the previous record they set with this equipment was in 2019!

That didn’t last long
It was only two years ago that BHP announced “Operational Decarbonisation”. They would build 550MW of wind solar and battery storage in the Pilbara region of WA. It was part of a $4 billion global budget for electrifying trucks and reducing carbon emissions. It was all so ambitious — they set a goal of a 30 per cent reduction by 2030, from 2020 levels, and net zero by 2050. The “Responsible Energy” message is still starring all over their home page.
Their diesel haul trucks use 1.5 billion litres of fuel each year, and they were keen to replace them with electric vehicles, which, they said would “save money”. But it’s all fallen in a hole already. The $4 billion USD global plan has shrunk to half a billion — a savage 88% cut. The new Pilbara solar and wind turbines were quietly shelved late last year (perhaps after Donald Trump won) but the news is only being shared now.
Meanwhile the electric trucks haven’t been invented fast enough so they’ve been delayed indefinitely.

ENI Katherine — might as well be a pagan temple to the Sun.

The Northern Territory is a test case for renewable energy and it’s a bonfire
In 2016, the new Labor Government waved a magic wand and commanded they would be 50% renewable by 2030. The experts said it was doable and would save $30 million a year. They gave out the permits for large solar installations, which began construction in 2019, but then suddenly changed the rules in 2020, and wouldn’t let the solar plants connect to the main Darwin-Katherine grid. Unbelievably, 64 megawatts of solar panels that cost $40 million dollars have sat, doing nothing, for four long years.
“It’s just reflecting back into space, not being used to power the grid and to substitute for diesel and gas turbine production,” said local vet Peter Trembath, who leased his land to energy company Eni Australia for the solar project.
“It’ll be some technical issue, but you’d reckon they would have sorted that out before Eni spent $40 million to erect it.” — Max Rowley, ABC News June 2022

Ponder how destructive solar power is: It only takes 13% solar to push a small grid to the edge
A little bit of solar power causes mayhem on a perfectly good grid.
NT Electricity Grid Map (Click to enlarge) Darwin is 1,300 km or 800 miles in a straight line from Alice Springs.
The Renewable Crash Test Dummy Country is aiming to be using 82% renewable electricity by 2030, but instead of making sure this works on a small scale at any one of our remote microgrid locations, where electricity is expensive to start with, we thought we’d do the experiment on the whole nation instead.
So it is “sobering” to see how this fails at Alice Springs. If there was a place on Earth that is well suited to wind and solar power, it surely is Alice Springs which is 1,200 kilometers from the Northern Territory’s main electricity grid. Surrounded by a million square kilometers of largely uninhabited arid land, if we can’t plaster enough solar panels and windmills here to support a town of 25,000 people with no heavy industry to speak of, where can we?
Yet the bare truth is that solar […]
Strap yourself in: Solar Power and batteries made a whole town 100% renewable (for 80 minutes).
It’s an Australian first! Put out a press release. No seriously, they did:
Solar and battery microgrid takes WA town to 100% renewables in Australian first
Western Australia has again demonstrated its remote renewable energy generation chops, after successfully powering the Pilbara town of Onslow entirely on a combination of large and small-scale solar and battery storage for a total of 80 minutes.
Only 520,000 minutes short of a whole year.
“The milestone achievement was announced by WA energy minister Bill Johnston on Friday morning after being demonstrated by state government-owned regional utility Horizon Power, which established the solar and storage microgrid next to an existing gas plant.”
Onslow is a metropolis of 847 people sited in one of the sunniest zones in one of the sunniest countries in the world. With at least 3650 hours of sun a year, Onslow vies for a top ten position globally.
If solar power was going to make it anywhere, this would be it. But we all know what keeps the lights on in Onslow and it isn’t solar power.

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.

Flinders Island is in the Bass Strait North of Tasmania.
If there is a heaven for renewables, this island should be it. But instead, even on Flinders Island, renewables aren’t cheaper than diesel generators. This is a dismal reality, yet the ABC promotes it as a fantasy poster-isle, interviewing only vested or “no idea” people, asking no critical questions, doing no counter research and telling us renewables will be “more reliable” and implying they are cheaper too. The ABC is a three-million-dollar-a-day advertising outlet for other government agencies. Instead of serving Australians it appears to be there to help shake down the taxpayer.
ABC renewables hype strikes again: Rhiannon Shine reports Flinders Island as a showcase of the brave new renewables world. Let’s translate that spin and see just how pathetic it is. If anywhere was going to be totally renewable, Flinders Island would be it — a first world island, tiny population, massive subsidies, no access to cheap coal or gas power, government support at every level and placed in a handy wind stream known as “the Roaring Forties”. Yeah! This is one of the last places in the first world (short of Antarctic stations) where renewables […]
