I guess the question is, where is the market? Australia is too small(atm) and foreign markets would be more likely to buy from local manufacturers.As I said earlier where has all the talk of building a battery manufacturing plant here gone? Just give Samsung. LG or Tesla a tax incentive to process here we have the ingredients just need the tech and Govt support.
Let's be honest the last Govt got CSL to build a vaccine manufacturing plant in Victoria, it's about time we moved on with secondary manufacturing and using our materials.
Why can't we supply our own grid batteries, we are going to need plenty of them.
Taxpayers, CSL to build vaccine manufacturing plant

The Morrison government will spend $1 billion over a decade to underwrite the construction of a new vaccine production facility to guarantee the nation continues to have its own supply of flu shots, antivenins and, if another pandemic occurs, the sovereign capability to look after its own citizens first.
Under the deal, CSL subsidiary Seqirus will spend $800 million to build a new state-of-the-art facility at Melbourne's Tullamarine airport.
Grid batteries should be easily assembled as they are container mounted, which would also make them easy to export, I would think we could be pretty competitive especially against EU and U.S manufacturers.I guess the question is, where is the market? Australia is too small(atm) and foreign markets would be more likely to buy from local manufacturers.
So I think it all depends on the size of the ev market here. Getting in early in battery manufacturing would help kick start th e EV take up.
Are we looking at a Mascot Towers like situation of defective standards or is this just a one off ?View attachment 169181

That'll be the problem.....

There's 5 in similar condition so it's an incident similar to the collapse of six towers in Victoria or the 2016 tower collapses in SA. There was also one taken out in Tasmania in 2022 although that was due to a landslip so not really a comparable situation but same end result.
looking at the state of that rather dry grass, its a surprise there were no fires started due to arcing.View attachment 169181

Ya gotta wonder about the so called resilience of todays community.Kalgoorlie faces a week without electricity amid heatwave due to WA power outages
Businesses close, and water supply, internet and fuel affected as outback town swelters in temperatures forecast to hit 40Cwww.theguardian.com
Given there's been 3 separate incidents, each involving multiple towers, over the past 7.5 years there's a need for a proper review of the standards in my view. SA 2016, Vic early 2020 and now WA in 2024.Are we looking at a Mascot Towers like situation of defective standards or is this just a one off ?
I think the issue that is causing a bit more angst at the grass roots level, is the backup GT's had no 'blackstart' ability FFS.That'll be the problem.....

I mean really, what intellectual midget thought that one up, FFs a major regional centre with one feeder line and the backup gen sets can't blackstart OMG. Probably saved a couple of grand in the planning phase of the project.
Someone must have gone down to Bunnings to get a portable generator, to get the GT's online. Lol
From the article:State had two-year heads-up on Kalgoorlie’s weak turbines: opposition
The state could have acted in advance to avoid much of the suffering thousands of people are now suffering for days on end, says the opposition energy spokesman.www.watoday.com.au
Five 50-metre transmission towers were razed, requiring a monumental effort from Western Power staff to connect the area back to the grid, which is still under way and is expected to take some time.
The resumption of power to Goldfields residents was delayed due to two Synergy-run backup gas turbines in West Kalgoorlie tripping on Thursday, immediately after they were switched on.
WA Premier Roger Cook said the generators tripped because they could only work if there was some existing power in the grid.
“My understanding is that the complete outage of the entire area was a very rare event,” he said.
“When those backup generators were switched on, they automatically tripped, because there was literally nothing in the system.”
Cook conceded the turbines were not fit for purpose in such a severe outage.
He said the government needed to look at backups, particularly as the state expected more severe weather in the future due to climate change.
Looking at the degree of oxidation on the barbed wire and the gal angle section, I suspect those towers have been up some time.View attachment 169182

So thats a bit less than one per year`.This document defines the asset management strategies for the Victorian electricity transmission network’s population of transmission line structures to maintain the safety, quality, and security of supply.
There had been 45 structure functional failures associated with eleven extreme wind events affecting this transmission network since 1959.
Perhaps the design standards of 1959 and onwards were a tad inadequate, but they have been upgraded.All failed structures were built to historical design standards with inadequate strength to withstand convective downdraft winds occurring during extreme storm events.
So there are still some lder structures in the network.Modern design standards produced in 2010 ensure sufficient structural capacity to withstand extreme wind events; however, structures designed to old standards still exist on the network.
Its a pity that the delta for this decline was not shown, but its an improvement.The mean time between failures (MTBF) of transmission line structures has declined since 1992 due to failures of low-strength towers in extreme winds.
So obviously age is a problem but we assured it is being addressed.Eleven structures along the Bendigo to Kerang line were replaced in January 2013, as well as reinforcement on 108 towers from the Dederang to South Morang 330 kV lines. Risk assessments reveal that 60 structures on the Murray Switching Station to Dederang 330 kV lines present health and safety risks due to their proximity to roadways and will be upgraded before 2022. The latest tower collapse event occurred early this year in one of the 500 kV circuits built 40 years ago, which is located along an open and flat terrain in the South West part of the network. The 7 permanent structures are scheduled to be installed later this year.
So despite the replacement and refurbishment program, the average age is 50 years. Given all the new transmission replacements, there must be some pretty old towers out there.The average age of structures is 50 years as majority of the fleet were erected prior to 1965. Primary inspection techniques indicate that the structures are generally in good condition.
From memory the line was done in the early 1980's.Looking at the degree of oxidation on the barbed wire and the gal angle section, I suspect those towers have been up some time.
Does anyone from WA know how old these towers might be?
While searching for some data points, I came accross this article from Ausnet Services.talking about the tower failures in the Victorian Energy network.
I wonder where all the equipment will go, and who actually owns the stuff.French renewable energy giant Neoen has confirmed the DeGrussa solar and battery hub in the heart of Western Australia’s goldfields region will be dismantled after seven years of operations.
The DeGrussa facility, comprising 10.6 MW of PV and a 6 MW lithium-ion battery energy storage system teamed with a diesel-fired generator, was commissioned at West Australian mining company Sandfire Resources’ Degussa copper mine site, 900 kilometers northeast of Perth, in June 2016.
The solar hybrid power system has since supplied nearly 20% of the mining operation’s annual power requirements and cut its emissions by about 12,000 tonnes of carbon dioxide a year.
Sandfire purchased the power under an initial 5.5-year agreement but that was extended as the mining operation pushed beyond its original 2021 closure date. The mine has however now ceased operations, signalling the end of life for the DeGrussa solar and battery hub.
In a statement shared with pv magazine, Neoen said it plans to remove the solar panels, as well as the rest of its facility and to rehabilitate the site.
Climate Energy Finance Director Tim Buckley said the dismantling came as no surprise with the end of mine life “absolutely well known” when they solar hybrid power system was commissioned.
“There is no surprise there,” he said, adding that in spite of its short lifespan, the DeGrussa power project has been a “brilliant success.”
According to AFR , the panels were supposed to have a life of 25 years, and its to get any metric of stats to convince that it was good investment.Buckley said the project, which attracted AUD 20.9 million ($13.7 million) in funding from the Australian Renewable Energy Agency (ARENA) and AUD 15 million in debt finance from Clean Energy Finance Corp. (CEFC), was part of the “step change that took solar from being a potential technology to being now integral to the transformation and decarbonization of the Australian electricity system.”
Soon, red dust will be all that remains of the $20.9 million of taxpayers’ funds invested into the project by ARENA. So, was it really worth it?
The legacy of the DeGrussa solar project isn’t particularly impressive when measured in dollars.
Market disclosures by Sandfire over the past seven years suggest a total of 80,687 tonnes of greenhouse gas emissions were avoided at DeGrussa because the mine consumed solar power rather than diesel.
Based on the $20.9 million committed to the project by ARENA, each tonne of greenhouse gas avoided at DeGrussa cost the taxpayer about $259.
That’s dramatically higher than the $32 a tonne carbon price implied by the market price for Australian carbon credit units (ACCUs) in December.
Neoen doesn’t appear to have made a major windfall out of the project either; accounts filed to ASIC over the past seven years suggest it earned about $28.6 million of revenue by selling power to Sandfire.
Only when ARENA’s $20.9 million grant is added, does the project’s revenue exceed the $43 million construction cost.
Neoen’s DeGrussa subsidiary paid just over $7 million of cumulative dividends over the seven-year period.
But Neoen has further costs ahead as it works to decommission the site after just seven years.

Jeez @mullokintyre I hate it when people do that, I've been scratching my head to remember the date, then a light bulb moment.From memory the line was done in the early 1980's.
The inherent nature of this stuff is it's durable. So long as corrosion doesn't get it, the insulators are maintained and the conductors aren't annealed then there's not much more to it unless some external force (extreme weather, landslide, etc) damages it.So despite the replacement and refurbishment program, the average age is 50 years.
I've suggested that but quickly realised I ought tread carefully there.Are we starting to reach pek solar home installation??
