South Australia's Renewable Energy Crack-Up

The Renewable Energy Crack-Up

MARITA NOON, September 1, 2016, 12:25 am

If a country’s goal is to decrease carbon emissions by increasing reliance on renewable energy, it only makes sense to install the new equipment in the location with the best potential — both in geography and government.

For Australia, which has a national Renewable Energy Target (RET) of 33,000 gigawatt hours of electricity generated by defined renewable sources by 2020, South Australia (SA) is that place. According to SA Treasurer Tom Koutsantonis, who is also the Energy Minister, the federal government had determined that SA is where “the best conditions for wind farms” could be found. The state government was amenable, with SA Premier Jay Wetherill promising to make Adelaide, its capital city, “the first ‘carbon neutral’ city by 2050.” The state’s RET is for 50 percent renewable energy by 2025. Wetherall, in 2014, claimed: “This new target of half of the state’s power to be generated by renewable sources will create jobs and drive capital investment and advanced manufacturing industries.”

In reality, SA has now found that talk is cheap, but renewable energy isn’t.

The decision to set a 50 percent renewable target is now being called “foolish,” by Tony Wood, an analyst at think-tank Grattan Institute, and “complete naivety and foolishness” according to Lindsay Partridge, chief executive at Brickworks, one of the nation’s leading providers of building products.

Now the largest producer of wind power, SA has enough installed capacity that, under ideal conditions, it could meet 100 percent of the current electricity demand. “However, wind generation tends to be lower at times of maximum demand,” according to the Australian Energy Regulator. “In South Australia, wind typically contributes 10 percent of its registered capacity during peaks in summer demand.” In fact, on some days, Jo Nova explains, they actually “suck electricity instead of generating it.”

Last month, SA experienced an energy crisis that the Australian, the country’s largest newspaper, blamed on “an over-reliance of untrustworthy and expensive wind and solar.” The paper warned that the federal RET “will force other states down the path taken by South Australia, which has the highest and most variable energy prices in the national electricity grid.” Nova adds: “South Australia has more ‘renewable’ wind power than anywhere else in Australia. They also have the highest electricity bills, the highest unemployment, the largest number of ‘failures to pay’ and disconnections. Coincidence?”

In July, the confluence of several factors resulted in a huge spike in electricity prices — as much as 100 times the norm.

In May, pushed out of the market by subsidized wind, SA’s last coal-fueled power plant was closed. Even before then, the Australian reported electricity prices were “at least 50 percent higher than in any other state.” According to the Australian Energy Market Operator, the average daily spot price in SA was $46.82 per megawatt hour. After the power plant was turned off: $80.47. In June: $123.10 — more than double the previous year. In July: $262.97.

Fred Moore, CEO of SA components manufacturer Alfon Engineering, addressing the electricity price hikes that are smashing small and medium business, says his latest electricity contract had increased by almost 50 percent. Until the end of May, his businesses electricity bill was about $3,000 a month and is now about $4,500 a month. He says: “I don’t know how long the company is going to be able to afford it.”

As a result of the loss of coal, when there’s no wind or sun, SA is now reliant on natural gas generation and from coal-fueled electricity being imported through a single connector from neighboring Victoria.

In part, due to a calm, cold winter (weather that is not favorable to wind farms), natural gas demand is high and so are prices. Additionally, the Heywood interconnector was in the midst of being upgraded — which lowered capacity for the coal-fueled electricity on which SA relies. Because of SA’s abandoning coal-fueled electricity generation and its increased reliance on wind, the Australian reports: “The national energy market regulator has warned that South Australia is likely to face continued price volatility and ‘significantly lower’ electricity availability.”

Then came the brutal cold snap, which caused more folks to turn on their electric heaters — thus driving up demand. The left-leaning, Labour state officials were prompted to plead for more reliable fossil-fuel-generated power. With the connector constrained, the only option was to turn on a mothballed gas-fueled power station — a very expensive exercise. The gas plant had been shut down because of what amounts to dispatch priority policies — meaning if renewable energy is available, it must get used, pushing natural gas into a back-up power source. This, combined with the subsidized wind power, made the plant unprofitable. The Australian Financial Review (AFR) explains: “Energy experts say South Australia’s heavy reliance on wind energy is compounding its problems in two ways, first by forcing the remaining baseload generators to earn more revenue in shorter periods of time when the wind isn’t blowing, and secondly by forcing baseload coal and gas generators out of the market altogether.”

Big industrial users, who are the most affected by the power crisis, are “furious about the spike in higher power prices.” According to AFR, Adelaide Brighton Cement, one of the few energy-intensive manufacturing industries still operating in South Australia, said the fluctuating price was hurting business. “As a competitor in a global market, it is essential for us to have access to the availability of uninterrupted economically competitive power.” In the Australian, Jacqui McGill, BHP’s Olympic Dam asset manager, agrees: “We operate in a global market…to be competitive globally, we need globally competitive pricing for inputs, of which energy is one.” The report adds that some major businesses in SA warn of possible shutdowns due to higher power prices — the result of a rushed transition to increased renewable energy. The Adelaide Advertiser reported: “some of the state’s biggest employers were close to temporarily closing due to surging SA electricity prices making business too expensive.” Not the job creation promised by Wetherall.

“Of course, if you were some sort of contrarian eccentric,” writes Judith Sloan, contributing economics editor for the Australian, “you could argue that escalating electricity prices, at both the wholesale and retail level, have made manufacturing in Australia increasingly uncompetitive and so the RET has indirectly contributed to the meeting of the emissions reduction target — but not in a good way.”

The SA energy crisis serves as a wake-up call and a warning to the other states, as the problem is, according to Koutsantonis, “coming to New South Wales and Victoria very soon.” But it should also, as the Financial Times reports, “provide lessons to nations rapidly increasing investment in renewables.”

Malcolm Roberts, CEO at the Australian Petroleum Production and Exploration Association, called the situation in SA a “test case” for integrating large scale renewable energy generation into the electricity grid. According to Keith Orchison, former managing director of the Electricity Supply Association of Australia (from 1991 to 2003), now retired and working as a consultant and as the publisher of Coolibah Commentary newsletter and “This is Power” blog, current policy is driven by “ideology, politicking and populism.”

Roberts added: “No technology is perfect. Coal is great for base-load power, but it’s not so great for peak demand but gas is well suited for meeting peak demand. You need gas as an insurance policy for more renewables.” Even the Clean Energy Council’s chief executive, Kane Thornton, in the AFR, “conceded conventional power generation such as gas would most likely be needed as a back-up.”

Perhaps the best explanation for SA’s energy crisis came from the Australian Energy Council, formerly the Electricity Supply Association of Australia, which called it an: “accidental experiment in how far you can push technologies such as wind and solar power in to an electricity grid before something breaks.” According to Orchison: “The council says that intermittent renewables at scale reduces carbon emissions but ultimately increases end-user prices and system reliability risks.”

On August 13, the Economist, in an article titled “It’s not easy being green,” addressed the three goals of Germany’s energy transformation: “to keep energy supply reliable; to make it affordable; and to clean it up to save the environment, with a target of cutting emissions by 95% between 1990 and 2050.” All three of which, Clemens Fuest, of the Munich-based Ifo Institute think tank, says, “will be missed.” He calls Germany “an international example for bad energy policy.” Now we can add South Australia, and, perhaps, most of Australia, as another.

This is the result, Orchison says, of “pursuing a purist view at the political expense of power reliability.”

The question remains: Will America learn from these bad examples, or will we continue down the path President Obama has pushed us onto — spending billions, achieving little environmental benefit, and raising rates on households and industry? The result of November’s election will provide the answer.

Been there, done that. California's Democratic Governor Gray Davis was booted from office in the late 1980's due to an over-zealous pursuit of renewable energy. His policies resulted in rolling blackouts that drove manufacturers and jobs from this state. These rolling blackouts were happening while some perfectly fine oil-fired diesel generating plants were idled by the emissions regulations of the California Air Resources Board. The political backlash led to two terms for Republican Governor Arnold Schwarzenegger.

During the peak of the energy crisis, Davis paid 62X the average cost for power on the national energy exchange. In just two more years, the 30 year bonds that paid for that one Summer of power will be paid off.

And another opportunity to explain how Texas became one of the largest wind power generators on the planet. The plan was never designed (let alone justified) with the goal of becoming "carbon neutral". Far from it: zero expectation of reducing our coal consumption. Wind expansion was planned as a SUPPLEMENT to coal fired generation. IOW to eliminate the need for NEW coal plant construction. Speaking of NG fired plants: our wind saved us from blackouts a couple of winters ago. A polar vortex knocked a couple of NG fired plants off line and wind (thanks to the high PV wind velocity) picked up the load. In fact for a short period wind supplied almost 40% of the demand for the entire state.

Alt energy goals can be met...if those goals make sense. The Aussie problem doesn't appear to be a wrong answer as much as it was the wrong question. IOW the alts can be the right answer...to the proper goals.

It seems you have an implicit assumption that alt-energy should be just a plug-in replacement for fossil fuels. Reasons to avoid fossil fuels such as climate change, pollution, and depletion suggest there is more required. The adaptations have to be system wide it appears, users, grid network, and sources. Maybe it is important to encourage smaller more flexible enterprises where production occurs when energy is available, but no great loss from sitting idle for a while.

I have no such assumptions as you mention. Instead, I have the belief that if we do a ground upwards re-engineering of our entire manufacturing, agricultural, transportation, and residential infrastructure, we could run our civilization on about 1/6th the total energy used now.

It should be possible to run our civilization and make 350M or so people reasonably happy within the US borders, with no imported energy and no imported foodstuffs.

Alternative and renewable energy would play a large part, and reduce FF consumption to minimal levels.

All we lack is the will to do so.

SA used to be a major manufacturer, steel & cars. The perfect storm of GFC, wind farms, Chinese iron ore processing, car makers moving offshore as conservative government withdrew manufacturing job subsidies, all left the State with no major manufacturing employers, besides the issues mentioned in the OP. Now they have a population over a million with as we say here, bugger all going on.
A ten year wine glut hasn't helped the agricultural sector. Mechanization of grape harvesting means 1/10th the Labour requirement. There was another major industry, cottage cannabis farming, also hit by sketchy electricity supply, roadside drug testing means nobody who needs to drive wants cannabis anymore. S.A. Is in deep doggie doo & there's no obvious answers.

KJ - "...in we do a ground upwards re-engineering of our entire manufacturing, agricultural, transportation, and residential infrastructure..." And what do you estimate the capex and time frame for such a replacement effort? A rough guess would be sufficient for now.

I believe that 25% of the USA's GNP for the next 30-60 years would do the job.

Obviously, that's huge - larger than the tab for WW2. But the alternative is that most of the 350M people in the USA starve.

Note also that the USA is then a walled country, surrounded by starving refugees. Except that Canada could do the same if they cared to.

IMHO, if we don't wall off the country, no amount of capex can save us.

Unless it is mostly for the wall 25% of GNP for 30-60 years is a little high. It reflects a syndrome seen in the housing bubble where the economy was building the economy. Now, I would agree that 25% of employment could be in agriculture and food distribution.

SA power outage: how did it happen?

South Australia and its 1.677 million residents were left without power this evening following severe storms this afternoon.

So have recent events and a focus on renewable energy created the 'perfect storm' for a state-wide blackout?

First, what happened?

SA Premier Jay Weatherill has confirmed severe weather destroyed a piece of infrastructure, a transmission tower, during the storm which led to the power-system protecting itself with a shutdown.

"Essentially what happened is massive set of power was removed and when that happens it trips the system," he said in a press conference this evening.




It looks like SA has a little problem on its hands. We will have to wait until tomorrow once the power is back on and people have had time to think about what really went wrong, but I am sure a high percentage of renewables without adequate back up generation and plans will be of major focus.
There surely has to be a way of compensating the traditional power generators to hang around to provide back up in time of troubles, or people will have to be a lot more proactive and provide their own back up generators.

The perfect storm a once in 50 year one.
Not really too many wind turbines just a monster storm and lots of bad luck.
Premier Jay Weatherill said the storm took down three transmission lines and nine towers in the Port Augusta region, forcing the electricity connection between South Australia and Victoria - known as an "interconnector" - to be shut down.

Wind turbines, which make up an estimated 40 per cent of the state's power generation, were unable to operate as winds were too high, South Australian senator Nick Xenophon said.

Mr Weatherill told media it was the "usual protocol" to isolate South Australia from the National Electricity Market in a situation where there is a "large frequency drop".

Shaved Monkey,

It is good to see at least someone is interested in a complete state in a first world country went totally black. SA have certainly had the perfect storm with electricity. One of the two transmission line from Victoria was out of action for maintenance/repair.So the storm only had to take out one line to have a devastating effect, which it did. We haven't heard too about how much wind energy was being produced at the time, but with such high winds, one suspects they would have been out of their working range due to high wind speed.

There has to be a way to encourage local backup power to be held in reserve, for such a remote market as SA with a such a high local level of long distance variable power.

Pusher - "...I am sure a high percentage of renewables without adequate back up generation". A tad difficult to sort out. For instance if there had been adequate ff plants available for back wouldn't the same problem develop if they used the same transmission lines?

And even bigger question: how much back up systems should be built and if they are wouldn't it fall mostly on the consumers to pay for what amounts to "unprofitable" infrastructure? After all what company can afford to spend $1 billion on infrastructure that sits idle most of the time. ExxonMobil doesn't have $32 BILLION in oil sitting in our SPR that cost it more $BILLIONS to build and maintain. And if it did how would it benefit them to use it in an emergency to keep oil prices DOWN?

If the extra infrastructure is primarily for the benefit of the tax payers then it's up to them to pay for it. Which gets back to why the Texas citizens have such a big chunk of wind power: they paid for the $7 BILLION expansion of our grid that was REQUIRED by the wind industry to justify its investments.

And an odd about situation here as to who is backing up who. A couiple of winters ago a very cold Arctic vortex shut down some NG fired electricity production. Had not high winds from the same storm pushed our wind out put to almost 40% of state electricity consumption we would have had blackouts. OTOH if the storm had also taken out those west Texas transmission lines connecting much of our wind power to the grid we would have taken a hard hit.

Back to the question that has plagued young daddies for decades: how much life insurance is too much? If you "plan" live to 68...don't buy any until you retire. If you have 3 kids when you're 29 and "plan" to die when your 32 you can't have too much life insurance.

So what exactly does SA have "planned" for future infrastructure failures? LOL.

Pusher - Let us know if you have any contradictory info then what I've found so far:

What did wind power have to do with it? Nothing. Nick Xenophon, Barnaby Joyce and others have been out blaming wind power for the blackout. But it is simply not true. Just before the blackout occurred, windfarms were producing about half the state’s electricity demand – they were not shut down as a result of the high winds. And ElectraNet, the owner of the downed high-voltage lines, made clear the blackout was caused by the storm damage to their network.

If the recently closed Port Augusta coal power station was still operating, it would have been cut off by the downed distribution lines too. And that would have likely made the disruption worse, since it would have created an even bigger sudden change to the network.


But that didn’t stop politicians and most media outlets reporting the false information. The irony is that if anything, more wind energy might have actually made the system more robust against this sort of rare event. The disruption occurred because of a sudden change to the network’s generation. And that happened because so much power was cut off at once. If there was more generation distributed around the state, it might have limited the impact of the loss of the transmission lines.

What exactly causer the blackout: One of the worst storms to hit South Australia in 50 years knocked out 22 high-voltage power pylons. The lines on those pylons carry electricity generated near Port Augusta to the rest of the state. When they went down, a cascade of automatic safety switches appear to have been flipped, in order to protect the rest of the SA power network – and indeed the rest of the National Electricity Market.

"Besides creating power, generators also affect the voltage and the frequency of the electricity network, which need to be carefully maintained to protect everything that’s connected to it. Aemo carefully models how that is likely to change in the short, medium and long-term, so that the networks can then make sure it’s sitting at the right values. When the 11 high-voltage power pylons were blown over, a huge chunk of power generation was cut off from the rest of the network. Dylan McConnell from the Melbourne Energy Institute says the market operator can’t prepare for very rare events like this."

IOW it would have happened if 100% of the electicty were fossil fuel generated. Sounds like those politians are just shilling for the ff industry.

south Australia could also invest in geothermal , wave and solar power , diversifying the mix of power generation

but that still wouldn't keep the power on with transmission lines down and substations out due to a estimated 80,000 lightning strikes

.
Having a functioning Grid is not simply having nominal installed generation
all those report gushing about the nameplate rating are simply rubbish good for "feelgood" evening news .
what matter is the lowest available power
this depend on output , transmission and demand ,
there ALWAYS must be an reserve of idle power for instant back up
usually this is rated as equal to the largest running unit
a mix of power generation units must be very carefully balanced ,
alternatives are lousy at baseline ,
they exist only due to political pressure by bigots on techno-ignorant politicians

P.S. the Dutch windmills were used to pump water out of the drainage ditch ,
being under sea level , Holland has a very serious rising damp problem
that's the very best use of wind power , it doesn't matter if it's intermittent
by the 19th century they were obsolete and were replaced by coal powered machinery .

Rockman,

Finally got some time to find some decent information.

Yes, I agree the short term event was caused by the weather knocking out the transmission lines from Port Augusta to Port Pirie

http://www.news.com.au/technology/envir ... 7fbe54b5ab
ElectraNet, which owns the transmission towers, said 23 towers appeared to have been damaged, including three out of the four transmission lines moving power between Adelaide and the north of South Australia.





Just to show you what level of penetration, renewable have achieved in SA.
In 2014, South Australia managed for the first time to get more than 100 per cent of its electricity needs for a working day between 9.30am to 6pm, from a combination of wind and solar energy.
Overall it gets more than 40 per cent of its power from renewables, and has a target of 50 per cent to be achieved within 10 years.


I don't believe renewables in Texas has reached this level of penetration, especially as Texas doesn't have any friendly state grids to act as a sink or spinning reserve.



http://www.businessinsider.com.au/heres ... lia-2016-9
Just under 1,000 megawatts of wind power was dispatching onto the grid at the time of the blackout with another 400 megawatts from gas plant and 300 megawatts supply from the Victorian inter-connector making up the total. Had either of the brown coal generators still been in operation the system would not have been any more resilient to this event.


Wind generation was providing nearly 59% of SA'power, 23% gas/local and 18% from Victoria.
Most of this wind energy is transmitted to the South East of SA via the Port Augusta to Port Pirie transmission lines that were damaged. Port Augusta, has decommissioned 760 mw of coal generation, and wind has basically made use of the transmission lines that were already in place. All good so far.

Adelaide has over 1700 mw of gas electrical generation capacity. Around the same as the total load on the dark and stormy afternoon in question, though only 400 mw was in use at the time.

The problem I see with the high percentage of wind power, is that the electrical distribution companies are force to take any and every megawatt the wind generators produce, which has lead to the back up gas power being put on the back burner as the gas generators can not sell their electricity at any price while wind is producing. The coal power generators were decommissioned altogether. The local gas generators are not allowed run at a level that can balance the market. They can only be used as a last resort.

The other problem with SA is they have many single failures points, due so many long distance transmission lines, which should be taken into account when determining hot spinning reserves. Ironical it appears where the transmission system failure was where they actually had 4 different transmission lines and they lost 3 of them, according to the article above.

Just a little geographical information on SA. 99% of the population live in 10% of the land mass.

To sum up my ramblings, the direct cause does seem to be transmission failure, but it was the drive to very high renewable targets, that has lead to an stable and fault prone electrical market in SA.

Pusher - Actually what was necessary to make wind investments viable in Texas was our govt spending $7 BILLION in tax payer money to upgrade our grid. And while we have had wind bump up to 40% for very short periods we're typically running around 10%.

But I suspect Texas economic growth is much stronger the SA. Our wind didn't replace 1 Btu of fossil fuel energy. But what it did accomplish was preventing the building of more coal/NG fueled plants. Plants that I guarantee you would have been built to supply our ever growing electricity demand. A demand growth we expect to continue for decades. Which also highlights this point just made:

"There ALWAYS must be an reserve of idle power for instant back up
usually this is rated as equal to the largest running unit a mix of power generation units must be very carefully balanced".

Which is why Texas is fortunate at both ends of the extremes: our ff plants can ramp up quickly is the winds stop blowing...uncommon as it is. But also in the recent past wind came to the rescue rescue when an Arctic blast knocked out some NG fueled plants and saved us from blackouts during one of the coldest snaps we've had in many decades.

Bottom line: Texas is going to get all the additional electricty it needs even if it has to come 100% from fossils fuels. Govt support of the alts could prevent that. But there's another bottom line: system failures will always happen but will tend to last for relatively short periods. But in the future much higher fossil fueled electricity costs could last many months...even into years.

And even worse: shortages shutting down businesses for long periods. These days with low NG and coal prices the alts don't look too attractive. But this isn't 2030...which sounds a long way off but in 14 years even with an aggressive alt build up starting tomorrow the SA could be taking a hard economic hit without more alts. And other industrial centers across the globe hit even harder. Loosing heat and AC for a couple of weeks or more isn't good but loosing many thousands of jobs for years would be much worse. We can always wait until the need becomes obvious to everyone... And the just wait 10 or 15 years to get some fixes in place. The we can listen to Aussie politicians piss and moan for years instead of for a month or two as they are doing now.

SA has some of the best potential for both geothermal and wave power......both of which are baseload (geothermal ) or near base load ( wave )

but there are significant vested interests in Australia who are trying to keep their business model going .....understandably....

also remember Australia is the birth place of Rupert Murdock.....
