Solar power from Australia to light up Singapore

From The Asia Times

The ambitious project may take more than a decade to finish, but the technology is almost ready

ByK.G. Chan

The desert outside Tennant Creek in Australia’s Northern Territory may hold the key to addressing Singapore’s future electricity supplies.

The world’s largest solar farm that could light up Singapore’s glittering shopping malls and office towers will be built on the barren dunes there.

It was reported that a huge amount of panels as well as supporting battery storage devices with a combined capacity of 10 gigawatts would be spread across 15,000 hectares of land there to ensure the solar farm could make the most of the outback’s clear skies and bright sunshine.

The bulk of the green electricity generated by this US$14.1 billion project would be exported to the city-state in Southeast Asia – equivalent to roughly one-fifth of its annual electricity consumption – via high-voltage submarine cables that will stretch about 3,800 kilometers.

Australia has abundant sunlight, especially in its Northern Territory.

The Northern Territory project to power Singapore, however, is still at a relatively early stage of planning.

The Guardian and Singapore’s Lianhe Zaobao reported that it could take four years for the massive solar farm to lock in finance, with production scheduled to start mid-to-late next decade. Yet the project is now under the auspices of both governments in Singapore and Australia’s Northern Territory state government.

Singapore aims to shed its reliance on expensive gas-fired power generation and on supplies from Malaysia and Indonesia, while Australia, with the best renewable energy resource in the developed world, also aims to export more green energy instead of liquefied natural gas and heavy-polluting coal.

Is it the Australians or Singapore that is virtue signalling? If Singapore leased land from Malaysia, it could build several multi-gigawatt nuclear power plants, and actually have dispatchable power for that price. I am quite sure the Chinese or South Koreans would gladly build them.

I agree we should stick it to those wealthy barons but what does that have to do with the Outback?

Barons leased land from the King that was known as a manor. They were known as the Lord of the Manor and were in complete control of this land. … The Barons kept as much of their land as they wished for their own use, then divided the rest among their Knights.

yeah mate its warm n sunny
it hits the high 30s and upwards often which stuffs solar panels I gather
they have some ripper dust storms
the natives might get a bit(lot) restless over their land being used for this
they had a decent quake up there last week
might cause alignment issues for pv stsyems if it happened again
then of course why the HELL would we be selling power to asia when were going to be having shortages and blackouts ADMITTED for Vic n SA this summer.
frankly the cityfolks deserve the blackouts to wake em up
but when you need power to fight fires using pumps for borewater, not for luxury like aircon..its lot different
Im so wildly angry
were flogging off our natgas for cents per kilojoule to asia
yet we cop near imported petrol prices per litre for our cars n trucks running on it
and our turbines etc for power gen
and no we dont need to frack onshore when we have offshore fields there thanks.
NTgovt is in the crapper now over the 99yr lease to china for their port
mil and other interests ie ussa want it taken back
mainly cos your mil madmen wanna put a base and missile launch system on OUR land
funny how usa wanting to make us a nice target is enough to get them looking to revoke the lease?

I live in Sweden where 50+ % of electricity comes from nuclear plants, and has done so for about 40 years. Nuclear plants do need careful maintenance (as do all power plants) but has proven to be extremely reliable.

The only form of power that is even more reliable (and needs much less maintenance) is hydro power.

I am a hydropower engineer. I can assure you that nuclear stations are more than 100 times safer than dams. Dam failures have killed more than 250,000 people.

If you shut down a nuclear station in an organised fashion, and nobody goes near it, nobody will get hurt. If you abandon a large dam, it will eventually fail and may drown millions of people.

Uranium can be extracted from seawater for about $300 per pound. While technically limited and not renewable, the resource is sufficient for many thousands of years. And there are other fertile / fissionable elements such as plutonium and thorium.

Regardless, it’s utterly impractical to transmit electricity four thousand kilometres under the ocean. Unless you first invent a room temperature superconductor.

Please post any links you are aware of, to information on currently operating thorium fuelled reactors.

But that’s a false dichotomy that doesn’t include all the other possibilities inclusing turning Singapore back into the small, sustainable fishing village it once was.

Singapore needs a reliable supply day and night. Solar power is good for about six hours per day. What is going to provide all the power the rest of the time? What is going to provide the power on a cloudy day or during a duststorm?

The cable will cost at least $300,000/ km – a total of ~ $1.2 billion for a single cable– and two will probably be needed.

Singapore would be far better off with small modular nuclear reactors that are safe, cheap, and reliable.

Correct..Having some experience with connecting solar farms to the grid. Trying to transport 10 GW of power, 3,600km will be not economically feasible. Mind you that ,nominal,10 GW is only good for about one hour at midday. The output dramatically rises and drops off as the sun moves overhead. High temperatures will cut the peak output to around 80%. The best solar farms are only operating at around 25% of their nameplate ratings, in terms of GWhrs delivered.

If they are going to install millions of these solar panels in OZ, they may as well use a solar panel that utilizes all the thermal heat that is wasted and make fresh potable water as an extra. The solar panel still generates the same electricity regardless of the thermal heat being used to filter fresh potable water through a low tech evaporative desalination process.

Since the solar panel gets hot roasting out in the sunlight all day, salty or brine water is heated with the panel and the water vapor wafts through a porous polystyrene membrane that filters out salt and other contaminants, allowing clean water to condense on the other side. The article below says it would generate 1.7 L per hour per panel. If you have a million panels, then that starts to add up to a small chunk of potable water they could use for a commercial use like agriculture or sell on the market. Water is becoming valuable too, and if these panels could do double duty, then maybe there is a bit more value to this exercise.

This is still a prototype from the article below, so not sure of the final specs. Don’t yell at me…

The only problem with the idea of using the panels to supply potable water as well as electricity is that they will be hundreds of miles from a reliable supply of feed water. Further, they are probably more than a thousand miles from where the potable water can be properly utilised. All of this amounts to a major project on its own, and it all hangs on the long term viability of the solar power scheme. I don’t think such a scheme is likely to fly.

Earthling2
Reply to  Eric Stevens
August 4, 2019 5:26 pm

Maybe just to clean the million panels..it isn’t a huge amount of water, but would be drinking quality potable water from any dirty water supply. Maybe 10-15 gallons a day per panel depending how efficient this process is and how many installed panels. There is usually some sort of ground water available in a desert via drilling wells etc, but may be brackish which would be ideal for this process. Could also catch any rain water and dew etc, so maybe more.

It is an interesting concept that should be explored, more I think for third world conditions where their water is either in short supply, real dirty and very expensive to obtain. The Israelis use drip irrigation in intensive agriculture operations and make their water go a long way, so perhaps there could be some type of intensive local horticulture operation along with this solar idea. At least there would be some extra productive use of the solar panel concept with may have some utility other than expensive electricity.

Well…

A desert area can be immensely fertile – if you can get water to the land. I don’t know the geology of the Australian desert, but we here in Arizona grow a lot of wheat, citrus, nuts, etc. So do the desert areas of southern California.

If you can contemplate building a 3,800 kilometer high power cable under the ocean, the idea of running a few hundred miles of pipeline / aqueduct to the ocean isn’t a big stretch at all. (The joker, of course, would be whether the energy required for pumping is too big of a bite out of the power generated.)

Supplying power when the sun don’t shine seems to be “handled” by a rather enormous battery farm. Now, does anyone ever contemplate that your battery farm has to be air-conditioned in the middle of a hot desert summer? (Accidentally leave your cell phone out on the workbench this time of year in Tucson. Pick it up a couple of hours later, and your 98% charge is down to 6%. My own stupid fault…)

Grow something that will be profitable enough to fund growing less-profitable plants that fertilize the soil these plants will be growing in.

No, the battery is probably there to overcome the “burstiness” of wind which can be generating hundreds of megawatts one minute, and next to nothing a few minutes later before the next burst. Think the eye of a hurricane for an extreme example. For solar imagine passing clouds.

Note that Elon Musk et al have been less than forthcoming about what the battery is good for. That in itself should be a clue that the damn thing is probably oversold even though it’s quite likely useful enough to justify the cost.

ColMosby
August 4, 2019 3:00 pm

Without doubt the dumbest most complicated means of producing power for Singapore.
No mention, as per usual , of actual production – just a claim that there will be a capacity
of 10 gigawatts, which will exist for a small portion of time at high noon, assuming no clouds.
and where will Singapore get its backup power from? No mention of actual outputs. Battery capacity also not mentioned but can’t provide max power for any extended period.
10 gigawatts of solar capacity generally translates to 50 or 60 gigawatt hours per day depending upon irradiance. That means it averages roughly 2 to 2 1/2 gigawatts during 24 hours. One can build the equivalent power capacity using small molten salt modular reactors, which cost roughly $2.5 billion for a gigawatt of continuous power or roughly $6 billion to produce the required 2 1/2 gigawatts of average power .It will require smaller and cheaper batteries to allow for the reactors ‘ power to be concentrated as necessary during the day and night. Unlike the solar system, it will not require costly backup power generation. And it can be accomplished sooner than this project. And Singapore will have no dependence upon Australia. The molten salt nuclear reactors will be probably 5 times cheaper than the solar system described.

…roughly $2.5 billion for a gigawatt. Ok, maybe if it’s been done already for near that, otherwise it might be 25 billion by the end of the first year of actual operation. Still maybe a better chance of a nuclear moon shot project than an undersea cable and battery.

And so is written the epitaph on cheap power prices in Singapore. These guys need to look pragmatically at the impact of renewables on power prices, the greater the penetration of wind and solar into our grids, the higher the electricity price. They want to swap thermal power generators at their doorstep in return for unreliable, intermittent electrons coming down a 3800km power line. Where previously Singapore’s grid costs (for local generators) was negligible, they can now enjoy an impost that will ~double (?) the power cost, particularly bearing in mind submarine cables can cost as much as ten times that of conventional overhead transmission. For what?. To swap the relatively negligible physical footprint of a thermal fleet for a 15,000 Ha solar farm. That’s 150Km2!. With the requirement to capture the latency in the system, the true capital cost is that of the solar installation and cable, and 10 Gw of conventional generation capacity.
Coincidentally, Singapore Power Group has recently introduced “Green” credits, where you can “buy” renewable energy. The final line of this article, where Australia plans to export more “Green Energy” in place of LNG and coal is not supported by the facts, where Australia is about to become the worlds largest LNG supplier, and has exported increasing tonnages of both thermal and metallurgical coal every year.

Dare I ask how long the batteries will supply power for at night or cloudy days? How much CO2 and fossil fuel is required to manufacture and install the solar panels and the 3,800 km of cabling? What will be the power loss over 3,800km of power cable and the horrendous environmental damage caused by its manufacture, installation and disposal at end of life? Who will take responsibility when it fails and they have blackouts? Also, as they will require fossil fuel powered back-up why don’t they just stick with the cheaper, gas fired power stations they are still going to require anyway?

It might be a good idea to use sodium-sulfur batteries. They operate at 300 degrees C. The largest existing plant in Japan has a capacity of 50 MW for two hours.

If we assume that those 10 GW during 6 hours is to be spread out as 2.5 GW during 24 hours it would take 450 Tsukuba-sized batteries. They are good for about 2500 cycles, so would have to be replaced over about 7 years, or a little more than one new battery per week.

The transmission loss for high voltage lines ranges from 0.5% to 1.1% per 160 km. The minimum loss over 3,800 km is then 11.2%, and the maximum 23%. T. Boone Pickens wouldn’t build his wind farms in Texas unless someone else paid for transmission lines to carry the power to…faraway Oklahoma! Sending power 3,800 km is more like generating electricity in New York and sending it by wire to California!

This is absolutely nuts. Better to use the power to synthesize methane from captured CO2 and electrolytically produced hydrogen via the Sabatier reaction, and ship it to the (existing) Singapore natural gas-fired power plants. Even then, the economics are anything but assured.

Not to overlook the up to 25% energy losses from converting Direct Current electricity to Alternating Current to enable sending energy long distance.

Fifty percent energy losses before Singapore gets usable energy.
What will be the cost of that electricity at their sockets?

One suspects this is a renewable energy dodge, much like ones already in use in America and Europe.
Specifically, the dodge where once renewable energy enters a general transmission line, all users interconnected can claim their energy usage is renewable energy?

Wow. Tennant Creek (pop. 3,000) looks to be on the northern edge of the middle of nowhere. Google maps Sat. view shows what looks to be hard desert. Many town are shown which have no road to them at all. Possibly mining towns with dirt roads, or classic “you just have to know the way”. The only road out to the south is to Alice Springs, several hundred miles away.
Great place for a solar installation, I guess.
These projects keep failing, and people keep building them.

The spot shown on the map is nowhere near Tennant Creek. It’s not even in the right state. Bear in mind that Australia is about the same land area as the 48 contiguous US states. WA takes up about one third of that space (think everything left of Texas) and the population of 2.5 or so million is clustered in the SW around Perth. Where that circle is located is about as desolate and remote as anywhere in Australia.

I often say, think of Perth as San Diego (similar climate even), and the nearest city is Houston (Adelaide). There is very little in between.

Also, why the heck would they build transmission lines all the way to Singapore? Surely it would be more efficient to use the energy to create a fuel (hydrogen?) and transport that to Singapore?

Yes, a very, very long under sea cable that would have very huge HVDC cable losses including from the rectification to AC/DC/AC. If they really wanted to use the OZ outback for solar generation, it would be much better to make a long term deal between Indonesia and Singapore, and take the HVDC cabe to Indonesia and use those electrons to power up part of Indonesia and then Indonesia sends a similar amount of their electrons on to Singapore after accounting for losses. The electrons go to the nearest load if designed to do so on the same circuit, so in effect OZ is is still selling the power to Singapore…it is just being cascaded down the line so to speak and becomes a bookkeeping exercise. The batteries would have to be located in OZ, and then the base load firm energy would be a lot lower than the peak output at noon. This is the way that selling large blocks of power can work thru multiple national utility’s such as BC Hydro selling electricity through WA and OR to California.

In Edison’s day, DC had to be used at the voltage it was generated at. Therefore you couldn’t have high voltages for long-distance transmission. So alternating current, with a voltage could be changed in a transformer, was the best choice.

Now we have high-voltage DC – up to 750 kV – that is converted from AC to DC and back again using electronic converters. Over long distances, this is more efficient and cheaper than AC transmission.

This location has very good solar resource. Tracking arrays will do much better than the 6.5 hours per day average depicted on the map. The average increases to about 9 hours full sunshine per day with tracking array:
https://www.rpc.com.au/pdf/Solar_Radiation_Figures.pdf
The output would not change much over a year because the loss in efficiency with rising temperature in the higher insolation period would reduce the output to a similar level to the lower insolation period.

This region does not get much cloud. There is little variation in insolation between best and worst days during the lower sunshine months:
http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=193&p_display_type=dailyDataFile&p_startYear=2018&p_c=-45908915&p_stn_num=015135

Tracking arrays have almost constant output from 9am to 3pm so, allowing for the time shift, this site could cover the morning peak in Singapore.

If there is a benefit, it would be related to the cost of gas and resultant fuel saving. At current gas prices in Asia approaching USD20/GJ (say USD180/MWhe), I expect this project will have economic merit despite the engineering challenges. It is unlikely LNG prices will fall in Asia.

I expect most large scale SSFs in Australia will use tracking arrays on at least one axis. The 333MW Darlington Point SSF will have single axis tracking arrays.

Without tracking ability, the SSFs in Australia have limited opportunity to generate. They are already curtailing lunchtime output during the peak of rooftop solar when wholesale price goes negative. That will occur more often as rooftop capacity steadily increases.

With tracking arrays, they should be able to generate enough in the morning and afternoon to make money. Those without tracking will only be able to deliver energy when the market is swamped with rooftop and prices collapse. The price of LGCs is so low now that they can no longer afford to send out power when the wholesale price goes negative. The coal plants know that they can keep generating and hurt the subsidy farmers rather than bearing the cost of taking plant off line.

Lunchtime power in Qld was down to AUD26/MWh on Monday 5th. Lunchtime power is forecast to be -AUD133/MWh on Tuesday 6th. These negative costs are becoming more frequent and SSF proponents have to be making forward projections.

While negative pricing for lunchtime power may not be relevant for Singapore, tracking technology is being increasing used in Australia and will certainly improve the economics of any large scale solar installation in Australia no matter what market it is supplying.

As other posters have noted there is so much bad with this idea. It really doesn’t make sense to just pick a few thing, but here goes. Supposedly this project would provide 1/5 of Singapore’s annual power need. Since many hours it would be zero, that would mean some hours it would be providing 40 or more percent of the total power. All that power coming in at one point would (without incredibly costly redundancy) , under a single contingency. So Singapore would have to have considerable amount of spinning resume ready to pick up should that source disappear.

Dust storm engulfs Tennant Creek
Posted 28 Feb 2005, 11:46pm

A thick dust storm has hit the outback Northern Territory town of Tennant Creek, reducing visibility to just a few metres.

Bureau of Meteorology observer, James Richardson, says the Barkly region’s dry February may have contributed to the amount of dust that the storm has shifted.

He says only 14.6 millimetres of rain has fallen in the region during the month compared to the average of 130mm.

Mr Richardson says the storm hit Tennant Creek late this afternoon but he expects it to pass through.

“From the north-east, it come in and we could see it at about two in the afternoon on the horizon,” he said.

“It’ll keep going past us and hopefully it will disappear.”

How long will the panels last before becoming uneconomic to operate?
How will they dispose of 150 square km of solar panels?
Will all the solar panels have concrete footings?
Will the land be rehabilitated after the solar farm is closed?
How long will the batteries last before needing replacement?
Etc

The capacity factor of solar farms is around 20% so the average output will be about 2GB.

A new high efficiency low emission coal plant could produce 2GB virtually 24/7 and occupy about 10 hectares and last 50+ years.

The solar farm will occupy 15,000 hectares (150 square km) and last about 25 years.

5 x 5 x 1,000,000 x $200 gives a cost of $5 Billion for 25 GWh of storage. Half the cost of 1 gw nuclear capacity.

If the cost of the cable scales from the CobraCable 0.7 GW x 300 km for $4.7 Billion, the 3800 km cable for 5 GW would run $425 billion.

Maybe higher capacity is not any more expensive, in that case it’s still $50 billion to connect.

Floating or undersea nuclear plants would be cheaper than the undersea cable, even if the solar plant was free.

Two nuclear power plants built locally using a modern design would supply all of Singapore’s electrical needs for 10 more years. I would build 3 smaller ones just for redundancy. No need of politics, submarine power lines, loss of power due to long transmission, batteries, or solar panels that need to be constantly replaced and last no more than 20 years. Using MSR, waste is almost eliminated.

One large dust storm and loss of panels, and loss of power. One long cloudy period, loss of electricity. One mistake dragging the ocean, loss of power.

I cannot imagine the risk assessment of this project ever giving the green light.

There are a few types of aolar PV cells. The output of silicon cells will drop by up to 0.007 per year / 15% in 20 years and the efficiency of new panels has steadily improved.

Where space is at a premium and more power is desired it might be worth replacing in 20 years, but most won’t actually stop working for 50 years or more.

If the batteries were in Australia, and there were enough of them, the cable major need to transmit only 30% or so of the installed capacity of solar cells. But the batteries would be impossibly expensive.

You are right that dust storms would be a major problem. It doesn’t take all that much dust to knock them back by 30%. Hordes of work for the teeming locals cleaning the glass.

I believe terms like “15,000 hectares” are disingenuous. Most people have no sense for what that means. I used google and discovered that it is an area 5.8×10 miles. Less than 60 sections of land. I think for most people, square miles or even square km is a more understandable term. I think hectares is used to make land area seem larger than it is.

Aye there’s probably a wee krack to drop the cable in.

Meanwhile businesses in Victoria Australia are installing backup diesel generators due to “when, not if” predicted power blackouts due to the fixation with the imaginary “renewables solution” the state government there has.

It’s common for farms, homes and businesses, hospitals, and critical infrastructure in Canada to have backup generators, especially in the 99% of the country where freezing to death in a winter power outage is a real possibility. I consider it part of the price we pay for living where there isn’t the most venemous… everything.

Long power outages are far less common here now than 30 years ago, because the equipment is better.

Most of our blackouts happen when equipment fails, or when ice, wind, or stupid people knock down utility poles.

And we already have the backup generators and a backup natural gas energy grid. ‘Cause we aren’t going to join the helpless whiners crying ‘climate change’ every time there’s a little deadly Canadian weather and the roads are closed.
