Until you purchase and have the battery installed you are in the same boat as any other South Aussie that fact remains no matter what you say. So the answer to the original question was NO.

Are you also saying this doesn't happen in SA currently?

For safety reasons, when your electricity supply from the grid is interrupted, your solar PV system must automatically and immediately turn off.
You really are not good at reading what I wrote as I never disagreed with any of what you have just posted... because you are too busy on your own agenda quoting a plethora of articles like all is factual.

I'm comfortable knowing I contribute way more to the grid than I use & have effectively already paid for my panels in a few years. This was both a good economic as well as environmental decision.

I said I don't have a battery yet a few times, but they are fast coming down in price, such that I will buy one within a few years once they become economically viable.

I gather you have no solar panels & don't know what it is like to wipe out your electricity bills. From my point of view, it is a great feeling to wipe out what was my biggest bills.

AEMO’s third report highlights wind power link to South Australia blackout
DECEMBER 12, 20164:32PM
A NEW report has shed more light on how the blackout in South Australia occurred and why wind power disconnected from the electricity network.

The Australian Energy Market Operator (AEMO) released its third report today with its preliminary conclusions on the causes of the “Black System” that plunged the entire state into darkness at 4.18pm on September 28.

While tornadoes were found to have taken down three transmission lines ahead of the blackout, the report suggests the system could have continued operating.

Instead it was the loss of power from the state’s wind farms that is thought to be one of the primary causes of the event.

The AEMO said a protection feature built-in to some wind farms, which the agency was not aware of before the blackout, caused some of them to reduce their output after a certain number of voltage dips.

The reduction in wind farm output caused the system to get more electricity from Victoria through the Heywood Interconnector, but the demand was so high that it tripped a safety feature, cutting off supply to the state. This happened within 700 milliseconds.

While some wind farms and other electricity generators remained online and continued to function for a short time, the loss of supply from the interconnector and other wind farms caused the frequency drop to below 47 Hz and they were permitted to disconnect, leading to the blackout.

The AEMO has released 15 recommendations to improve the system and a final report is due to be published in March 2017.

WIND FARM OPERATION

The blackout highlighted that many wind farms have a protection feature which causes turbines to disconnect, stop operating or reduce their output if they experience more than a preset number of voltage dips within a two-minute period.

The AEMO said it was not aware of this protection feature before the SA blackout and this behaviour was not included in any stimulation models the wind farms submitted to AEMO.

Interestingly the AEMO said this type of fault has never been reported to the agency, and it was not aware of any reported instances of this phenomenon occurring internationally.

Wind farms are programmed to recover from voltage dips and some of the wind farms continued to operate and successfully rode through the faults.


But three of them disconnected or stopped producing power after their sixth voltage dip, ultimately leading to a drop in power generation from nine wind farms.

The AEMO will investigate why these three wind farms acted this way for its final report.

The number of voltage dips each wind farm is designed to withstand varies and AEMO is working with wind farm operators and manufacturers to review their settings.

Some of these settings have already been increased to provide extra capacity but AEMO noted improved limits would still be insufficient to avoid power drops among some wind farms if the September 28 events were repeated.

“Risks in this area still remain and will be assessed further in AEMO’s final report,” it said.

The loss of multiple wind farms has also been reclassified as a “credible” contingency event that is “reasonably possible” so that South Australia’s power system is operated with enough redundancy to withstand this type of action without breaching its limits.

It also noted about 20MW of wind power was disconnected due to excessive wind (typically more than 90km/h) in the last five minutes prior to the blackout but this was not a major contributor to the event.

WEATHER EVENTS

On the day of the blackout AEMO did a risk assessment at 8.30am when the maximum wind forecast was 120km/h and decided no action needed to be taken.

AEMO didn’t review this decision after an updated forecast at 12.57pm predicted winds of 140km/h (gusts) but post-event analysis found this would not have changed its actions anyway.

However, the AEMO has recommended this be changed so that reassessments are done.

The report also dismissed suggestions the blackout was caused by lightning strikes.

While there were 263 lightning strikes in five minutes in the Melrose region, the AEMO believes it’s unlikely they caused any of the five electrical faults and six voltage disturbances ahead of the blackout. This is because the lightning strikes looked to be cloud-to-cloud, not cloud-to-ground, in impacted areas.

But it does believe tornadoes that appeared near three transmission circuits between 4.05pm and 4.35pm at Brinkworth and Davenport, could be to blame.

“This information corroborates the conclusion that tornadoes were the cause of the five electrical faults that occurred before the system separation,” the report said.

It’s believed these tornadoes may have damaged the towers or conductors.


The Bureau of Meteorology reported wind strengths ranging from 190km to 260km/h in localised areas and evidence of tornadoes.

A fourth transmission line was damaged after the blackout but this has been blamed on severe winds.

But an AEMO analysis also found South Australia’s electricity system could have continued to operate despite the loss of four transmission lines due to storm damage.

“Based on AEMO’s initial static modelling, it seems likely the SA grid could have withstood the loss of all three power lines, and the fourth damaged after the Black System,” the report said.

RESTARTING THE SYSTEM

The AEMO reported that the restart ancillary service (SRAS) was unable to supply enough power to fully restart a major generating unit so the system was only started via the Heywood Interconnector.

By 8.30pm, about 40 per cent of the load in SA capable of being restored had been restored. This had grown to about 80 to 90 per cent by midnight. The remaining load was restored as transmission lines were repaired, with all load restored by October 11.

RECOMMENDATIONS

1. More rigorous processes be put in place to monitor weather warnings during extreme weather conditions, for changes in forecasts.

2. Develop better process for information exchange and reclassification decisions when faced with extreme wind speeds.

3. Assess risks on assets when wind speeds are forecast to exceed wind turbine over-speed cut-outs or rapid changes in wind direction.

4. Investigate developing a system protection scheme such as load shedding or generation tripping to avoid loss of connection with Heywood Interconnector.

5. Review allocation of load between under frequency load shedding blocks.

6. Investigate the feasibility of developing a system protection scheme to ensure a stable island within SA if the interconnector goes down.

7. Investigate the level of risk to power system security if power is lost from a concentration of wind farms, and develop measures to manage any material risk.

8. Review the system restart in detail to allow quicker identification of equipment that shouldn’t be used, speed the restoration of load, improve communication and other improvements.

9. Review the test plan against the actual system restart plan to identify differences.

10. Regular testing of the start of a low voltage generator alone.

11. Develop detailed procedures on the differences required in power system operations during periods of market suspension and any desirable rule changes.

12. Investigate whether a better approach could be taken for ensuring the minimum stable load of generating units is taken into account as part of the National Electricity Market dispatch process.

13. Review market processes and systems for changes to implement those improvements.

14. Develop a more structured process to source and capture data after a major event.

15. Investigate the possibility of introducing a process to synchronise all high speed recorders to a common time standard.

The closure of Victoria’s Hazelwood coal-fired power station will add $78 a year to energy bills around the country, a new analysis shows.

South Australians will be hit the hardest, with $150 a year set to be added onto household bills.

Victorians will get an extra $99, while Queenslanders will face an extra $28, thanks to the upcoming closure of Australia’s cheapest power generator.

The Australian Energy Market Commission 2016 residential electricity price trends report found wholesale energy prices will jump 36 per cent thanks to Hazelwood’s March shutdown.

IGA network owner says he’ll be sacking staff as his power costs will double next year

A LOCAL businessman says he has no option but to cut staff numbers at his three supermarkets because of huge increases in his power bill.

Andrew Williamson, the owner of Hackham Foodland and the Victor Harbor and Morphett Vale IGAs, said his new electricity contract price would more than double next year — costing him an additional $130,000.

Mr Williamson said the nature of the supermarket industry meant he couldn’t pass on the extra costs to customers.

“Staff will have to go. It’s the only way in the competitive market we’re in. People still expect to pay $1.99 for milk and get their cheap bread,” he said, adding staff were told of the need to reduce wage spending but that he’d yet to decide how many jobs would go.

Former Kapunda Foodworks owner Noel Allen said he was “absolutely furious” about power prices and reliability, accusing the State Government of killing country towns. Mr Allen, who owns pharmacies in Roxby Downs and Port Augusta, said a lack of electricity reliability was doing significant damage to regional areas. “What does it do to a town like Roxby when BHP can’t operate (at Olympic Dam)? I’m not just reliant on power reliability, I’m reliant on those workers keeping their jobs,” he said.

Energy Minister Tom Koutsantonis said he “absolutely sympathised” with businesses battling increasing power bills but said the 1999 privatisation of ETSA meant that the Government had limited options in regard to price.

“But we have met with many independent supermarket operators and are helping them negotiate better contracts with retailers,” he said.

Mr Williamson has been searching for a new electricity contract for about six months ahead of the expiry of his current deal at the end of the year, but offers weren’t palatable.

“I’ve currently got a deal of 8 cents per KWH on peak and 4 cents off peak,” he said.

“But under a new 12-month deal, that will go up to 18 cents per KWH on peak and 9 cents off it.” He added: Compared to our interstate counterparts, we’re getting completely smashed. I don’t place all the blame on the State Government but there’s been a failing somewhere and them blaming someone else doesn’t cut if with me.”

The Opposition’s energy spokesman Dan van Holst Pellekaan said rising power prices were an issue for all businesses in SA, regardless of their size.

“Even the large commercial users are finding they have no bargaining power because the energy retailers setting contract prices are so fearful costs will rise further,” he said.

“It means that they’re offering very high prices and requiring businesses to make snap decisions.”

Mr Koutsantonis was adamant that the introduction of an emissions intensity scheme was the solution to reducing power prices.

“Prime Minister Malcolm Turnbull needs to start listening to the experts rather than the far right of his party and put an EIS back on the table,” he said.

Mr Koutsantonis also urged businesses to apply for assistance under its $31 million grant program to help businesses conduct energy audits.
 
Turbo sympathises with business owners and still uses the privatisation of ETSA as his governments excuse for high power prices. Who's fault was it for wind farms and shutting down the Port Augusta power station? The previous Liberal govt? Stop the blame game and do something for once!

Both sides of politics seem intent on the blame game rather than actually solving the problem, for which we pay their salaries.

Surely we should have a decent national grid to better safeguard blackouts.

Someone (in HK) is making unbelievable money, whilst we pay top dollar for a substandard system.

Bring on those cheaper batteries to store electricity...

✔@PeterTreloar

Just heard - 66KV line back on #StreakyBay#Ceduna and surrounds have mains power again. Unreliability remains a significant issue and cost.




Elliston Mayor Kym Callaghan said phones were also out, which created a potential risk in hot weather for both locals and holiday travellers through the outback region.

"There are some tourists [who] once their mobile phone goes off they get a bit lost," he said.

"They need to restrict their travel because if they have an incident on the road, there's going to be no coverage and they're not going to get any help."

A wind gust of 111 kilometres per hour was recorded at Ceduna during Friday's storm.

Outages 'beyond a joke'

It is the third prolonged blackout in the west coast region of SA in about three months after storms damaged power lines twice during September.

Customers took to the SA Power Networks Facebook page, some in support of the workers toiling in today's heat to repair the damage but others scathing of the latest outage.

"Better have Xmas a day early so the food doesn't go off," Josephine Graham wrote.

"Feel for everyone concerned especially the guys fixing the lines — maybe sharing a fruit mince pie with them will make everyone appreciate the job getting done!"

Toni Miller wrote: "Spare a thought for the crews who have to work in this horrible weather to make our lives more convenient and comfortable."

Streaky Bay Mayor Travis Barber said the string of outages was "getting beyond a joke".

"The last one went for three-and-a-half days. We've got people running around trying to buy ice. Everyone's got all the food for Christmas organised," he said.

"You've got tourists down the caravan park [with] prawns and strawberries and cherries and they're all trying to buy ice."

Mr Barber said local business operators and council staff were being kept very busy trying to help the influx of Christmas holidaymakers.

"They've worked throughout the night trying to keep generators running to empty sewer pits of the caravan park and of the local hospital," he said.

He said his area had not suffered the stormy weather directly, but had been affected when damage happened elsewhere.

"In the city it goes off for a few hours, over here we're out for a few days at least. It seems we're the first ones shut off and the last ones to come back on and that's the real frustrating thing."
 
Pretty decent sized storm about to hit.

Get your candles ready!

Already 7,000 homes out in the mid north.

What is with all the crazy weather in the past few months. A couple of decent storms before the great blackout, then he great blackout, then the hail storm, now this.

All pretty much since the Crows season finished!
 
Was a crazy night with violent winds & heavy rain. My local park is mostly under water.
Not you i hope??

Mate was told 8:00pm and had hers back on a couple of hours ago.

SA Power Networks tend to overestimate the restoration time and then get it back up and running beforehand.
6.30 and no power. Was hoping that'd be the case but no such luck yet.
