Nice, so what happened to the excess ?
Distributed to other states, put into storage or lost ?
SA Power Networks (SAPN) distribution network load:
View attachment 132532
Below zero yes so we've now had several occurrences, dates as above, where load on the distribution network in SA drops below zero. That is, customers connected to the distribution network are generating more than they're using at that time.
Note for those not aware, the distribution network is what supplies electricity to homes, shops, offices and so on and does not include anything connected directly to the transmission network (eg mining and heavy industry).
This is thought to be a world first for a large scale power system, the only precedents being small islands and things like that.

The path to the fusion Nirvana has been littered with failures and downright frauds (who remembers Pons and Fleischman?).Nov 5 (Reuters) - Helion Energy, a fusion energy tech startup, on Friday said it raised $500 million to build a net positive electrical generator, one that creates more power than it uses.
The latest round values the company at $3 billion. Helion said $1.7 billion in follow on investments were committed if it can prove its technology works, which would be a major step toward making fusion technology a practical solution for generating power while emitting no carbon.
Fusion is the process that fires the sun as the nuclei of two atoms fuse under extreme heat. It creates enormous amounts of energy.
Helion’s newest prototype named Polaris will add a so-called regenerative energy technology to its fusion technology already developed to generate electricity, said Helion founder and CEO David Kirtley. The target date for demonstration is 2024.
The company broke ground in Everett, Washington in July to build the generator which will be the size of two shipping containers and create enough electricity to power 40,000 homes, said Kirtley. If it works, the $1.7 billion follow-on investments will be used to develop a commercial system, he said.
“There's a real future for fusion to be part of this climate change and clean energy discussion,” said Kirtley, adding that other fusion energy companies were also pushing the timeline forward. He said there were over 40 private fusion companies today.
Fusion has advantages over fission as the fuel is derived from water, not radioactive uranium or plutonium and doesn’t generate long-term radioactive waste.
Sam Altman, a well-known investor and artificial intelligence researcher in Silicon Valley who led the round, said the long-term goal of Helion is not just to create clean energy but electricity that costs just one cent a kilowatt hour.
One of the forgotten Energy sources has been Nuclear Fusion 9as distinct from Nuclear Fission).

It would be an outstanding breakthrough if someone were able to construct a net positive Fusion reactor.

The answer is "all of the above" but it depends on circumstances.Nice, so what happened to the excess ?

For all older installations there's a much cruder system in place which, to my knowledge, hasn't been tried anywhere else globally. Just intentionally push the voltage up and the more modern ones will reduce output whilst older models will simply cease functioning altogether once a threshold is reached.
Given it has only been used once, and only in a fairly limited part of the state on that occasion, I can safely say there's no link.So this is why people are reporting household appliances burning out, due to higher voltage ?
As has happened on Perth's "freeway", which most of the time during working hours, is a parking lot.As an analogy, that approach is akin to fixing traffic congestion on a highway by simply blocking some of the roads which lead onto it. If vehicles can't get on the highway well then they can't overload it - brutal to those affected but it does achieve the objective.
MickScott Morrison’s electric vehicle strategy – a key plank of the government’s target for net-zero emissions by 2050 – will accelerate the rollout of charging and hydrogen refuelling stations across the country to support 1.7 million electric cars on the road by 2030.
As car manufacturers release timelines to end production of conventional vehicles, the Prime Minister said the government’s strategy would not force Australians out of their family sedans, utes and trucks.
Mr Morrison, who accused Bill Shorten of “ending the weekend” as the Coalition weaponised Labor’s electric vehicle strategy at the 2019 election, will spend $250m building charging stations in cities and towns and supporting businesses and governments transition to electric fleets.
The Future Fuels strategy – to be released on Tuesday and expected to drive more than $500m in combined private and public co-investment – is forecast to help slash carbon emissions by more than 8 million tonnes by 2035 and avoid $224m in electricity network upgrade costs.
Driving down transport emissions is considered crucial to achieving carbon neutrality by mid-century, with the government planning to create more than 2600 jobs through the construction of charging infrastructure across 400 businesses, 50,000 households and 1000 public-access fast-charging stations. New public charging stations would be accessed by up to 84 per cent of the population, covering about 21 million people, and reduce health costs by $200m to 2035.
Mr Morrison said the Future Fuels plan was designed to avoid taxes and offer “choices not mandates” as electric vehicle prices fall in line with demand.
AS we have been saying as demand increases and the technology improves, so will the infrastructure, it was pointless throwing in infrastructure when there was no demand and no supply and the E.V charging protocols were different from vehicle to vehicle.It would seem that someone in the coaliton must be reading ASM.
They have finally issued a plan.
Not sure if its a good or bad plan, will need to wait for the technical details to come out, but at least now they have a "plan".

AS we have been saying as demand increases and the technology improves, so will the infrastructure, it was pointless throwing in infrastructure when there was no demand and no supply and the E.V charging protocols were different from vehicle to vehicle.
That is true, also there is still only two manufacturers making V2G compatible cars, by 2025 all vehicles have to be V2G compatible, which is great but as usual early uptakers may be wedged, if they want to use import/ export pricing.There is STILL no demand and no supply.
Both sides want to intervene in the market. For Labor that is their ideology, for the LNP its a response to people like Biden and BoJo saying we are not doing enough.
That's the biggest problem with the entire energy debate not just EV's.The biggest problem Australia has had, is the ranting and chanting has been by those with a political, or financial agenda, it had nothing to do with the technical and financial realities of E.V uptake.
These are fairly long term ambitions, and the danger with long term ambitions or plans or execution thereof , is that events can overtake them over time.PARIS, Nov 9 (Reuters) - France will build new nuclear reactors to help the country lessen its dependence on foreign countries for its energy supplies, meet global warming targets and keep prices under control, President Emmanuel Macron said on Tuesday.
With concerns over purchasing power topping opinion polls five months before the presidential election, at a time of soaring energy prices, Macron said the decision to go for new reactors was essential to keep prices "reasonable."
"We are going, for the first time in decades, to relaunch the construction of nuclear reactors in our country and continue to develop renewable energies," Macron said in a televised address to the nation.
This was meant "to guarantee France's energy independence, to guarantee our country's electricity supply and achieve our objectives, in particular carbon neutrality in 2050," he said.
As Europe grapples with steep increases in energy prices, France is taking a different path from neighbours like Germany.
Germany responded to the 2011 Fukushima nuclear disaster in Japan by accelerating its national exit scheme for reactors.
Macron gave no details, but his government is expected to announce the construction of up to six new pressurised-water reactors within the coming weeks.
There's an order of magnitude scale difference there. A sub or even an aircraft carrier are far smaller than anything normally built for a nuclear power station (well, apart from early prototypes etc).Perhaps one of the reactors may make its way into an OZ sub??
I wonder where he will get the uranium fromFresh from his rebuff from Australia's "non" to the diesel electric subs, the French President has outlined his nuclear credentials by announcing plans to build new Nuclear reactors

On the subject of power stations with a coal supply crisis, Bluewaters in W.A , has problems of its own.There's been quite a bit of concern about the possibility of the Yallourn coal mine (Vic) flooding which, if it happened, would put the Yallourn power station out of operation.
Well there's heavy rain forecast and Yallourn has indeed run into trouble.
Not with a flood though - the coal conveyor caught fire earlier today.
The power station is still operating using coal in the bunkers and there's no immediate threat of the lights going out. Still, can't win it seems, if it's not a flood then it's a fire.
Not surprisingly, the Tas govt won't end up with much as they rank behind the lending banks in the list of creditors.The Singaporean owner of the Basslink cable connecting Victoria and Tasmania has put the business under rather than pay the $105.3m the state and Hydro Tasmania claim to be owed over the 2015 failure of the power and internet connection with the mainland.
Basslink is the only physical connector for power and internet services to Tasmania and, in addition to smoothing Tasmania’s own power grid, plays a role in stabilising the National Energy Market when power demand fluctuates in the summer months.
The cable’s owner, Singaporean-listed Keppel Infrastructure Trust (KIT), called in voluntary administrators on Friday after APA Group walked away from a potential acquisition of the undersea cable, with Basslink’s lenders appointing KPMG as receivers in the wake of the decision.
While the decision throws open the future of the ownership of the interconnector, Basslink chief executive Malcolm Eccles said there would be no disruption to power supplies to Tasmania.
“The Basslink Interconnector continues to operate efficiently and reliably, connecting Tasmania to the national electricity market. We continue to serve the communities of Tasmania and Victoria, providing a reliable and sustainable source of energy.”
KPMG’s Peter Goddard said in a statement that Basslink’s business “will continue to operate as usual and there will be no disruption to the operations of the interconnector or communications as a result of this appointment.”
According to an October disclosure to the Singapore exchange, KIT’s Australian subsidiaries owe its banking syndicate $625.8m, and a standstill agreement of its repayment expired in late October.
In a statement to the Singaporean exchange KIT – which booked earnings of $S295.3m ($299m) in the first nine months of the year – said its decision had also been triggered by letters of demand from state-owned Hydro Tasmania over about $58.6m the power provider says it is owed over the 2015 failure of the cable – a figure which Basslink disputes on the “basis and quantum”.
Basslink was also ordered to pay $46.7m to the Tasmanian government in December 2020 after arbitration over the line’s five-month outage, which caused major power supply issues in Tasmania as the state government was forced to ship in diesel generators to make up the power supply slack, and widespread outrage as internet services degraded to businesses and households.
