Quite right about the skin effect, but most of the world uses 50Hz (which makes the skin effect even more negligible)...don't know if this project envisions 60Hz or 50Hz or some other frequency.
lol even just playing the song "Thunderstruck" over drone footage flying over that gigantic NT solar farm would be a great promo video! The proposed solar farm allotment shown at timestamp 2:03 is 12 MILES long and 6 MILES wide (or 20 kilometres by 10 kilometres). Bigger than Manhattan Island! I want to see the drone footage!
@@aave865 Good choice too! Links for the lazy: AC/DC - Thunderstruck: ruclips.net/video/v2AC41dglnM/видео.html Men At Work - Down Under: ruclips.net/video/XfR9iY5y94s/видео.html
The skin effect is miniscule at 60hz. The reason why they use DC is because of AC capacitive coupling. Basically, AC can conduct through non-conductors, but this effect is proportional to surface contact with another closely positioned conductor. This is a small but non-negligible issue when AC is transferred over long distances over land, where AC couples with the semi-conductive ground. It is still manageable, and is not much of a concern outside safety. Its only a big of a problem when these wires are placed in the ocean, where everywhere is extremely conductive salt water. Electrical power transfer over sea is always via DC to prevent this sort of capacitive losses.
THANK YOU! I was just about to comment on this. First time I see asianometry making a mistake :). All of Europe is one massive synchronous grid, but the UK is not connected due to the sea. They're connected with HVDC instead. As that's just a short distance, using HVDC would make no sense going by the videos explanation.
Was he right about the small losses using HVDC? Also, I'd no idea the Chinese were using HVDC above ground with power transmission from the 3 Gorges dam. I heard they were using giga-volt potential. Gigavolt DC equipment must be pretty impressive.
It's strange that the price tags of these monumental and important mega projects are in the same dimension as the acquisition of some app that gets aquired by some tech giant. Prices really are a strange thing. But II need help! I've been bingewatching this great channel for hours now!
@@rayhans7887 if the numbers are correct, you might might be able purchase a single aircraft carrier and perhaps a few F-35 aircraft for the cost of this project.
All acquisitions like that are priced based on future performance and not current current or past costs, especially in tech this has been a self-reinforcing spiral making everything crazy priced. These projects have costs based on actual real world things like resources and man hours, rather than fantasies of perfect performance over many years to come.
Enjoy your binge. The awesome thing about this channel is that there’s a lot more to come. Unlike TV shows that either get worse over time or just end.
The main issue with running AC underwater, is from induction losses since salt water is a good conductor, the cable acts as a large capacitor. This isn't an issue with DC
It can be develop to ferroresonance right? And i think main issue is Singapore is not friendly to Malaysia and Indonesia , then Singapore turn to Australia which make higher cost.
As an Australian engineer the thing that I find most curious about this project is that they propose to export the electricity to Singapore - rather than use the electricity locally to convert it to other useful things (hydrogen, aluminium, fresh water, cement, steel.. etc). I think we'd do better exporting energy-embedded materials than simply the electricity.
It is a proposal from Singapore to import. It clearly says so in the description and content. Australian governments have been extremely hostile towards renewable projects. There is a lot of coal in Queensland. This kind of project would be out of character for any Australian government.
Well, if this project proves to be economical despite the extensive cable lengths, it could open up further possibilities. For example a nuclear plant in Alice Springs providing electricity for the entirety of the mainland so that Tasmania can then keep its hydroelectricity for itself
@@spdfatomicstructure Nuclear?? There would be too much opposition in Aus. As the video shows Aus has an abundance of solar and hydro, adding wind installations and related proposals, "big" batteries going in all over the country, nuclear is not needed.
@@TheHsan22 Solar does not produce power through the night. Coal power is still going to be needed for the night, and I doubt hydro would be sufficient to replace all the coal power. Nuclear power is the best solution, and everyone i've ever spoken to all agree. I live in Australia btw and i've never met anyone as far as I know who opposes nuclear power. I think it's the mining companies lobbying to keep coal power the dominate source of power because I don't think there is that opposition among the general population.
I like the idea of using a desert area as a major source of solar power. However, did I miss any mention of the risks of placing an undersea cable directly along the line of some of the highest seismic activity in the world?
Another big advantage of HVDC between countries is that you don't have to synchronise their grids which you can't even do if you're going between a 60Hz and 50Hz country.
not just borderline insane, but truly insane. still, if it happens, some people will get very rich while the Australian taxpayers will suffer the consequences, though they wont suffer as much as the Uyghur slaves in the Chinese solar panel factories. No one in their right mind thinks this will use Australian made products.
There is also a plan to build a huge solar array near Pilbara in Australia and use its output to electrolyze water into green hydrogen. This will be liquified and shipped to other Asian countries, where it can be used to generate green electricity among other things. So there is an alternative way to eliminate the fossil fuels and not have to transmit electricity long distances. If you're reading this, I guess you should make a video about this plan.
For those interested, that project is called "Asian Renewable Energy Hub" and was originally another submarine power cable project (from Pilbara, Western Australia not central Northern Territory)
liquified hydrogen for export is nonsense, it takes huge energy to liquify it, their are no ships capable of transporting it and no infrastructure to burn it upon arrival. For less energy you can just synthesize hyrdocarbons from the hydrogen and ship that. Or utilize the hydrogen to directly smelt Australian iron ore into steel and export that.
An important point you miss here is that the per km transmission losses for an HVAC cable are much higher undersea than they are on land, which is not so for HVDC. So the breakeven distance for HVAC vs HVDC is FAR shorter underwater than on land. Basically noone builds underwater HVAC cables for more than a few kms - more than that and you need HVDC.

The Tasmanian cable failed because Bass Link cooked it by pushing it to it's limits to sell Hydro power to the mainland when prices were high. We would usually be OK for our power here in Tassie as we have heaps of hydro and wind power, but there was a drought on and they had run the damns down to risky levels. Although we have a backup gas generator it would not have coped, so Hydro Tasmania had to import a heap of contingency generators to guarantee supply (I knew the guy who was organising all this and it nearly killed him with the stress). Singapore would be well advised to have a workable back up plan if their cable from Oz failed.
I think they said 20% of total power so it actually would improve the diversity of the sources of supply but they would need some excess capacity to allow for failure in any of their sources including this one.
That is why the Gordon below Frankiln should have gone ahead. And it will sometime, when idiot Brown is dead, you watch, if you are still alive by then! How grows the Tassie population ?
So, all the Hoo Ha surrounding the Dams issue ( '"'Let the Rivers Run Free".... B. S. ) will, sooner or later be overuled by some 'progressive' govt. some day wanting to generate clean power for a burgeoning population of immigrants who won't care a twig for all Browns bull !
Australia vast desert is the perfect fit for solar farm, hot and dry help keep the maintenance low. And of course Australia is friendlier than muslim countries.
_" possible to have the solar/battery farm built in nearby Malaysia or even Indonesia?"_ I agree, it sound "complicated" and really Australia could use all "green energy" they can produce by themself and not export it, Australia have the highest CO2 emissions/capita in the world among "major" countries, even worse than the USA

If anybody is interested, Singapore is supposedly not well-suited to wind power, with low-to-intermittent wind speeds (2 meters per second) where commercial turbines supposedly operate at 4.5 meters per second. Also the waters around Singapore are busy shipping lanes, so there supposedly aren't actually that many places to put the wind turbines.
How expensive are either 1) Singaporean electricity, and 2) Indonesian land to make this economical? You'd think it would be far easier to make a profit from supplying solar to Australia, or building solar plants in Indonesia (it's not cloudy all the time), or to sell the electricity to Java and save thousands of miles in undersea cables
Exactly, coupled with aboundand Geothermal Energy in Indonesia there shouldn't be a problem for a shortend Sea Cable. Except, politics. Maybe Singapur doesn't like Indonesia OR it's a media stunt. Singapur and Australia are far more advertisable than Indonesia.
@@juliane__ Recently a Singapore public media published an anti/pessimistic Indonesia nuclear power source propaganda video. Instead of supporting their neighbor country or providing neutral insights from technology view, they just went stamped whole nuclear power technology as bad and all Indonesians as incompentent developing country people from politics and conservative environmentalist views. Little did they know, Indonesia is going to harness the safe thorium nuclear energy commercially by 2028 according to the current blue print. The nuclear power plant will be built in Bangka Belitung area which is really short to Singapore. In that video, they also worshiped solar energy as an only viable option. They neglected the geothermal potential completely. It's clear that they don't like us. Also the estimated electricity selling price from the thorium molten salt reactor is 0.7 cent/kWh and the current existing geothermal plant's is 6-9 cents/kWh. I wonder how cheap this Aussie solar electricity from the so-called Sun cable, not even counting the high sabotage risk on this long cable. The line must be very hard to break and very efficient to transport the electricity in 4500 km distance eh
hello Jon at Asianometry, I have been listening for a long while and, thank you. I have learned much and see some things differently. I enjoy your work, please, keep at it.
Thank you for your effort in delivering such a good presentation! Allow me to point out a minor detail, in that ABB did not exist in 1954. ABB is the result of a merger of Swedish ASEA and Swiss Brown-Boveri companies much later in the twentieth century. Cheers!
The Asian Renewable Energy Hub (a different proposal to the Sun Cable) is suggesting something similar after they changing from their original submarine cable approach. Solar + wind farm in the Pilbara region of Western Australia to produce ammonia and ship that over for "green hydrogen". The Sun Cable company is pursuing the (much cooler in my opinion) HVDC approach. Right now it's all private investors betting on these renewable energy megaprojects, so it doesn't hurt you if their investments fail. I'm glad there are people with the capital and risk tolerance to invest in these really exciting solar farm and HVDC submarine cable approach! For the sake of our carbon dioxide levels I hope they succeed :)
Maybe in the future when Hydrogen can be generated, stored and used more efficiently. Right now the entire process is much, much less efficient that simply transmitting the power directly.

Appreciate 8:06 give the north islands power comes from south island hydro generation. Most people live in New Zealands North Island and most electricity comes from the South Island. So a HVDC cable connects the two islands.
A good book on laying underwater cable is by John Steele Gordon, "A Thread Across The Ocean" on the first laying of the Atlantic telegraph cable, about 170 years ago. Same problems with cable and deep seas.
Indonesia has lots of geothermal electricity potential and it's way closer to Singapore than Australia. And geothermal runs constantly so no storage would be needed. Wouldn't that make more sense?
This is just speculation, but it could be because unlike Indonesia Singapore has almost no fossil fuel production of their own and already must import natural gas to provide for their electricity needs. Indonesia meanwhile is the world's fifth largest coal producer and eighth largest natural gas producer and can provide relative cheap domestic supplies of these fuels for their electricity needs. So there's a very different cost proposition in switching electricity sources between the two countries. It might seem like adding intermediate access points would make sense even if the furthest points would still be the most economically attractive. But given this requires at a minimum additional conversion stations it comes at a high added cost. Timor produces a fairly modest amount of natural gas but its electricity demand is a tiny fraction of what Singapore's is anyway so it's basically irrelevant.
@@espfusion looking at the expenses from this video. I would think it would be better for Singapore to build a nuclear power plant instead. Ample of long term power with lower cost than this project.
I understood East Timor has abundant fossil oil/gas within it's borders. It'd be far more fesable, to use that to generate power and transmit it to Singapore.
Great video explaining from the technicalities to the economics of the project. Seeing that Indonesia is along fault lines, any idea how earthquakes might affect it?
great video on a really interesting yet unexplored topic! I'm from Singapore and rooting for the success of these renewable energy projects - hopefully we can sort out the technical and political issues.
I've spent a fair bit of time in Singapore over the years, and loved it. However, maybe Singapore can start using less electricity...? Maybe Singapore could import cheap electricity from its neighbours instead....?
@@cerealport2726 If Singapore thinks it is more economical to import solar power from all the way from Australia instead of its neighbors, I think that says all you need to know how "cheap" the electricity is from its neighbors.
@@exoticredtadpole2713 They mostly use gas to generate electricity now, imported from their neighbours. It's cheap, certainly cheaper than building an interconnecter many times longer than the longest ever built, and only able to deliver 2.2gigawatts. You're obviously of average to low intelligence, and certainly not an engineer or scientist if you think this project is viable financially, or logistically.
The big issue isn't transmission but storage. The video skims over nightfall. So what happens when the sun sets in Australia? Zero electricity traveling down the Sun cable. Singapore will still need power. Despite skimming over this, it is simply not possible to build any lithium battery large enough to cover for Singapore's nightfall sorry. Adelaide Australia installed the then world's largest battery in 2017 (Hornsdale Power Reserve). That battery can only power the city of Adelaide for 10 minutes. Singapore is 4 times the population of Singapore.
I stack my solar panels electrically to double the voltage and minimize transmission losses. Probably not making a huge difference even with my extra long coiled wire that needs to be trimmed to a reasonable length, but at least they kick on earlier and off later.
When they first built Basslink, they saved money by only using one conductor and letting the reverse current flow through seawater. Unfortunately, that caused the Bass Strait oil platforms to start dissolving due to electrolysis. I'd like to know what a kilowatt-hour of electricity would cost in Singapore?
Why can’t they find space for solar farms in Malaysia or Indonesia? Surely they can use the solar panels to partly shade crops so they get a double whammy?

The map that was shown multiple times is incorrect, it shows the cable entering the sea in Kimberley region of Australia, which is a long way from Darwin. Compare with the correct map shown at 15:17
Yes, the line going through Darwin was in the wrong place, and so is the starting point (near the town of Elliot, NT). I have helped get this corrected for this video's thumbnail but unfortunately the video itself is already released and can't be changed. Side note: there is/was another similar project called the "Asian Renewable Energy Hub" that wanted to build a submarine cable from a solar farm in the Pilbara, Western Australia. But they've switched to a plan involving using solar power to produce hydrogen/ammonia fuel and transporting the energy by cargo ships not electrical cables.
I think a bigger problem with AC, especially underwater, is that the cable forms a capacitor with the surroundings and thus there is an AC current to ground. The longer the cable, the bigger the capacitance, the higher the loss.
I'd guess for a cable that long you'd be very keen to minimise the amount of copper even if it means spending much more on ultrahigh voltage converters and switching gear. So you'd want it as high as technically feasible with those converters - currently 1.2M volts, though the limit is still slowly rising (largely driven by those massive Chinese projects).
I read recently that solar panels are more efficient if they are cooled by floating on water. IF true, they might be better to make a closer floating farm.
We have recently built the largest floating solar farms on our reservoir, and one on the straits of Johor. Another one is being built in Batam and will generate energy for both Batam and Singapore.
Sad facts. -At best you get 10h (in summer) of usable solar energy per day. -Battery storage is rubbish, only real storage is pumped hydro -A problem mining companies have come up against when installing solar farms is dust. Basically to have to be constantly cleaning the panels out there. With even small dust layers dropping output 15-20%. -Solar Cells are really only good (in a commercial sense for ~

The losses on AC transmission through cables are much higher than the calculation here. Due to the physical proximity of the conductors in a sea cable, they have a very high capacity. A 4000km cable would have around 0,4mF capacitance, resulting in a reactance of around 10Ohms at 50Hz. Its basically a dead short. There is basically nothing arriving at the other end.
That looks crazy, aren't Indonesia and Malaysia much closer? Wouldn't it be easier to produce energy in, say, Borneo ? Maybe it couldn't be solar, but there would be other alternatives, no? Like, say, hydro or wind.
Indonesia doesn't have a desert to create a solar farm and their waterfalls are not that large to create a surplus of electricity. Also Indonesia is more population dense than Australia, so electricity surplus is harder. Australia has a lot of advantages, in addition to other political reasons. Also Indonesia might buy electricity from Australia this way. Note that the proposed route also intersects the places that Australia has major interest. Indonesia still have had to agree though*. Edit: it's Singapore that hasn't permitted, not Indonesia
We have trial to import energy from Malaysia. www.channelnewsasia.com/news/singapore/singapore-importing-eletricity-malaysia-power-energy-13775308 Not one word from our government have been said of this. Other then mediaouts around the world tripping themselves making articles and interviewing the CEO, earning him free PR hype and potential investors.
On another note. Yes Singapore would not have the land mass to implement solar panels but it is surrounded by water. Makes a lot more sense to develope tidal currents to develope power. The water is always moving
"A few rooftop solar panels on residential buildings. That is about it." - this statement is absurd. You certainly have not heard of Singapore's largest floating solar farm covering 45 football fields on our reservoir. It is also expected to reduce carbon emissions here by around 32 kilotonnes per year, the equivalent of removing 7,000 cars off Singapore's roads.
1 million VAC subsea is the way to go. It's been implemented onland from Moscow to Siberia in 1989. The challenge is subsea earthquake around Indonesia Island. If I was a Singaporen investor, I would invest in Kalimantan Indonesia instead.
Others have suggested that too, I suggest checking out the video at 14:13 and comparing the amount of sunlight Kalimantan receives compared to Australia, then Googling "Kalimantan weather report". To talk the investors out of building that undersea cable you have to convince them it is more expensive than building the solar farms five or more times bigger to produce close to same amount of energy. Earthquakes _might_ damage the cables, daily tropical storms _will_ cause problems for solar and wind power. Maybe they should look into geothermal and tidal energy instead.
1. Subsea cables cross tectonic boundaries all over the world. 2. And put the rainforests in Kalimantan at further risks when they are already in great danger? No way.
@@huaiwei Oh yes, that too. Australian Outback can easily fit these huge solar farms and the local environment would probably thrive with the shade they give. On Kalimantan you not only have to cut down the forest, but because the tropical weather reduces the amount of available light you actually need to build at least two farms to match the one proposed for Australia, meaning more forest needs to be cleared... But it gets better, as just about only way to calm down the people who would protest this project is to promote how it produces clean energy... Oh, wait... So next you would have to cut down even more rainforest to build more solar farms so the locals can get clean solar power too. Also, cutting down rainforests tends to cause erosion so the solar farms might get washed away by floods or destroyed by a landslide.
1. Damage to undersea cables is hopefullly very rare but is always difficult to repair..Was that the Basslink problem? 2. The reason for transporting the energy from Australia is that Australia has lots of solar-exposed space. I wonder how much investigation has gone int finding solar resource closer to Singapore. Offshore perhaps.
Singapore has reportedly passed a law that no single source can provide more than 25% of Singapore's electricity. That spread your risk approach seems to be how they approach international relations. They try to make sure their economy and security is not overly dependent on either the United States or China. Whether they are getting the balance right can be debated, but that's their strategy.
@@UltimateAlgorithm Traditionally , no one wants a nuclear power plant in their "backyard" and all of Singapore would be the backyard . Secondary issue is : Where do you store the nuclear waste , some of which will be deadly for ten thousand years ? That would most likely require an international agreement for not only a remote storage location, but the rights to shipping it by cargo ship . Cost to benefit ratio kicks in .
way and way more money, if you think there's no politics friction between Indonesia and Singapore while the lands are neighbor for million of years, you gotta be kidding
@@biketech60 I mean so little space so much power needed, density requirement kicks in. Solar and wind are some of the least dense power available. Nuclear on the other hand is very dense in terms of space to power generated ratio. For the waste, just drill deep down. Create an underground storage space 500 meters or more beneath the surface.
Considering that Australia is basically the prime source for uranium in the world, it would’ve made a lot more sense for Singapore to invest in small modular reactors instead.
I lived in Singapore many year ago, during that time, many private residences were being built. If each of these private residences were fitted with a 10 kilowatt solar system feeding into the grid, they would not be in the dire straights with electricity they are. Moreover, going down that road, they are not reliant on anyone else and cannot be held to ransome. Reports I have read suggest power from this proposed solar farm in Australia would be used to manufacture hydrogen which can then be exported and used for varius uses.
Japan is working on a similar project, but the electricity generated in Oz is first converted to Hydrogen, then compressed, and shipped to Japan. There the procedure is reversed to supply electricity. I wonder how Australian folks feel about the potential destruction of their homeland over these types of projects. A quote I learned years ago definitely applies to these types of projects: "The Law of Unintended Consequences."
@@MsEverAfterings Exactly, while not all of them are remote as the one in the video, most are in the middle of nowhere and are usually built on depleted and nonviable ex farming land for the ones somewhat near population. Nearly all the big ones are out in the middle of whoop whoop. My friend has worked on a number of these solar farms in Aus and most are literally nowhere on inhabitable land.
Have you ever been to Australia? Obviously not; if you had you would know that there is a whole lot of nothing outback with no people and thousands of square kilometers of semi-desert ! If anything, those solar panels will provide shade and moisture for a little more life to form/colonise the area !
Importantly, Australia is politically stable and has a long history of supporting Singapore thought it's history. Importantly, support for Indonesia, has always been strong.
I'm surprised that the battery backup proposed is for onsite with the panels. I would think you'd have the panels feeding battery backups onsite with your use end point (Darwin, and in Singapore) . That way you are using your batter storage after transmission losses, rather than before, so you need less total battery. It seems like if your batteries are housed with the panels, some percentage pf your battery bank exists solely to be lost in transit.
Just personal thoughts but by storing at the production end: 1/The most expensive part of the total system (the cables) can be built thiner since they just gonna have to be sized for day or night consumption and not in proportion of the peak production moments (when the sun shines at max in Australia). 2/ By retaining power on the production side, the proportion of losses along the transport will also be lower since the intensity will also be lower 3/The investor has a better control on the electricity price since it can release power at peak price moments (at this scale of energy, prices per GWh can almost double in a matter of hours) and improve its profitability. 4/They could maybe count on low cost/low density battery technonolgies that seem to be currently under development taking advantage of the australian desert abundance of space.
I am surprised Singapore sovereign funds are not involved in this, needing private seed monies. Is 3 GWatt is about 25 Terawatt hours in 1 year? That will be half of Singapore's yearly power consumption.
I'm surprised one of Australia's retirement funds (the "superannuation" system) hasn't invested in it, with trillions under management hungry for long-term infrastructure projects. But I guess the project might be too high risk right now. I'm sure they'll invest eventually.

As for SG, the whole changes is too far different from the original agreement and thus they wanted a new agreement instead.
Am I missing something? How much electricity does Singapore actually need? Wouldn't it be cheaper to install a bunch of solar panels and wind turbines on their high rise buildings in combination with offshore energy generation tech closer to singapore? Also is thermal energy not feasible there?
Why can't they run the line over land when you get into the islands the rest of the way to the destination? And have a small solar farm to step up the power.
Very interesting report. In Sweden the government is realizing the big electrification by windmills all over the country and especially in the north. Beside destroying ”the last wilderness of Europe” it needs huge powertransmission to the south and to the European grid. We now know that sun and wind cannot save us due to the needed backup when wind and sun low - cold and dark winter neither works. The EU had forecasted 90.000 windmills around the Baltic Sea in their latest. Technical Report. Global players backing investments in “green tech” and generate a political fear in climate crisis. Lobbying/corruption. Renewables are not fossilefree if you study their lifecycle demand mining, manufacturing, installation and decomissioning. So why not use the small modular nuclear plants derived from the many hundreds you find in military vessels. They can consume old nuclear waste - no mining, compact in space, prefabrication, easy transport, safe cooling with air convection, placed where needed, heat for heating/cooling/desalination/waste Ideal for Singapore and others. Please do a video about this Kind regards Torbjorn Sjodin, Sweden
Your maps are drawn wrong. Darwin is on the "middle hump" of northern Australia. You keep showing the cable coming from the "left hump" near Wyndham in Western Australia's Kimberley region.
I thought skin effect only comes into play at either higher frequencies, or else at very thick cables. I would have thought stray inductance and capacitance would be the main parasitics in electricity transmission? I'm no expert though.
Electrical Engineer here. You are indeed correct. The Skin effect contributes to additional losses but is quite low in 50 Hz or 60 Hz systems. The main reason for these losses are parasitic inductive and capacitive effects on long transmission lines. Not to math it out to much but for each delta x (change in distance or length of the cable) there is a delta L (change in inductance in case of rising x it's an increase) and a delta C (change in capacitance)

@@markedwards4879 “High Voltage” is definitely the song for it
The skin effect is miniscule at 60hz. The reason why they use DC is because of AC capacitive coupling. Basically, AC can conduct through non-conductors, but this effect is proportional to surface contact with another closely positioned conductor. This is a small but non-negligible issue when AC is transferred over long distances over land, where AC couples with the semi-conductive ground. It is still manageable, and is not much of a concern outside safety.
Its only a big of a problem when these wires are placed in the ocean, where everywhere is extremely conductive salt water. Electrical power transfer over sea is always via DC to prevent this sort of capacitive losses.
THANK YOU! I was just about to comment on this. First time I see asianometry making a mistake :). All of Europe is one massive synchronous grid, but the UK is not connected due to the sea. They're connected with HVDC instead. As that's just a short distance, using HVDC would make no sense going by the videos explanation.
You can’t use dc at that distance.
This. Skin effect only really kicks in at much higher frequencies.
Was he right about the small losses using HVDC? Also, I'd no idea the Chinese were using HVDC above ground with power transmission from the 3 Gorges dam. I heard they were using giga-volt potential. Gigavolt DC equipment must be pretty impressive.
Why is Hydro-Québec's transmission line to New England HVDC then?
It's strange that the price tags of these monumental and important mega projects are in the same dimension as the acquisition of some app that gets aquired by some tech giant. Prices really are a strange thing.
But II need help! I've been bingewatching this great channel for hours now!
Truly. Also compare with military procurement Mind-boggling
@@rayhans7887 if the numbers are correct, you might might be able purchase a single aircraft carrier and perhaps a few F-35 aircraft for the cost of this project.
All acquisitions like that are priced based on future performance and not current current or past costs, especially in tech this has been a self-reinforcing spiral making everything crazy priced.
These projects have costs based on actual real world things like resources and man hours, rather than fantasies of perfect performance over many years to come.
Maintenance costs start to grow the instant the project is finished vs a application which is expected to make more money as it grows
Enjoy your binge. The awesome thing about this channel is that there’s a lot more to come. Unlike TV shows that either get worse over time or just end.
The main issue with running AC underwater, is from induction losses since salt water is a good conductor, the cable acts as a large capacitor. This isn't an issue with DC
It can be develop to ferroresonance right?
And i think main issue is Singapore is not friendly to Malaysia and Indonesia , then Singapore turn to Australia which make higher cost.
As an Australian engineer the thing that I find most curious about this project is that they propose to export the electricity to Singapore - rather than use the electricity locally to convert it to other useful things (hydrogen, aluminium, fresh water, cement, steel.. etc). I think we'd do better exporting energy-embedded materials than simply the electricity.
It is a proposal from Singapore to import. It clearly says so in the description and content. Australian governments have been extremely hostile towards renewable projects. There is a lot of coal in Queensland. This kind of project would be out of character for any Australian government.
Yes, energy embedded material manufacturing is a great way for Australia to go! I hope support for this huge economic opportunity grows.
Well, if this project proves to be economical despite the extensive cable lengths, it could open up further possibilities. For example a nuclear plant in Alice Springs providing electricity for the entirety of the mainland so that Tasmania can then keep its hydroelectricity for itself
@@spdfatomicstructure Nuclear?? There would be too much opposition in Aus.
As the video shows Aus has an abundance of solar and hydro, adding wind installations and related proposals, "big" batteries going in all over the country, nuclear is not needed.
@@TheHsan22 Solar does not produce power through the night. Coal power is still going to be needed for the night, and I doubt hydro would be sufficient to replace all the coal power. Nuclear power is the best solution, and everyone i've ever spoken to all agree. I live in Australia btw and i've never met anyone as far as I know who opposes nuclear power. I think it's the mining companies lobbying to keep coal power the dominate source of power because I don't think there is that opposition among the general population.
I like the idea of using a desert area as a major source of solar power. However, did I miss any mention of the risks of placing an undersea cable directly along the line of some of the highest seismic activity in the world?
Egypt thought about it and came to the conclusions it's stupid. They opted to build NPPs instead.
You like it but solar panels need water to cool. Deserts don't work.
Yes Pass by the ring of fire.
@@CountingStars333solar photovoltaic panels don’t need cooling. There’s plenty of them out in some of the hottest places on the planet.
So destroying thousands of Sq kilometres of desert doesn’t bother anyone these area are not devoid of life and are often more sensitive
Another big advantage of HVDC between countries is that you don't have to synchronise their grids which you can't even do if you're going between a 60Hz and 50Hz country.
Thanks! If you didn't post this, I would never have known about this borderline insane megaproject!
Agree ... Insane ...
I actually found it out on wendover productions or his friends lol I don't even remember which channel

@syanin dita Yeah, good point !
not just borderline insane, but truly insane. still, if it happens, some people will get very rich while the Australian taxpayers will suffer the consequences, though they wont suffer as much as the Uyghur slaves in the Chinese solar panel factories.
No one in their right mind thinks this will use Australian made products.
There is also a plan to build a huge solar array near Pilbara in Australia and use its output to electrolyze water into green hydrogen. This will be liquified and shipped to other Asian countries, where it can be used to generate green electricity among other things. So there is an alternative way to eliminate the fossil fuels and not have to transmit electricity long distances. If you're reading this, I guess you should make a video about this plan.
For those interested, that project is called "Asian Renewable Energy Hub" and was originally another submarine power cable project (from Pilbara, Western Australia not central Northern Territory)
liquified hydrogen for export is nonsense, it takes huge energy to liquify it, their are no ships capable of transporting it and no infrastructure to burn it upon arrival. For less energy you can just synthesize hyrdocarbons from the hydrogen and ship that. Or utilize the hydrogen to directly smelt Australian iron ore into steel and export that.
They are not cost effective we export coal why not burn it ourselves . there is something wrong in Canberra it stinks of corruption
@@usausa2390 You are obviously blissfully unaware of the challenges faced by the planet primarily caused by carbon emissions !
@@TonyWhite22351 tell what is your solution
An important point you miss here is that the per km transmission losses for an HVAC cable are much higher undersea than they are on land, which is not so for HVDC. So the breakeven distance for HVAC vs HVDC is FAR shorter underwater than on land. Basically noone builds underwater HVAC cables for more than a few kms - more than that and you need HVDC.

Going back through your older videos, interesting to note that earlier this year the plan fell apart.
The Tasmanian cable failed because Bass Link cooked it by pushing it to it's limits to sell Hydro power to the mainland when prices were high. We would usually be OK for our power here in Tassie as we have heaps of hydro and wind power, but there was a drought on and they had run the damns down to risky levels. Although we have a backup gas generator it would not have coped, so Hydro Tasmania had to import a heap of contingency generators to guarantee supply (I knew the guy who was organising all this and it nearly killed him with the stress). Singapore would be well advised to have a workable back up plan if their cable from Oz failed.
I think they said 20% of total power so it actually would improve the diversity of the sources of supply but they would need some excess capacity to allow for failure in any of their sources including this one.
That is why the Gordon below Frankiln should have gone ahead. And it will sometime, when idiot Brown is dead, you watch, if you are still alive by then! How grows the Tassie population ?
So, all the Hoo Ha surrounding the Dams issue ( '"'Let the Rivers Run Free".... B. S. ) will, sooner or later be overuled by some 'progressive' govt. some day wanting to generate clean power for a burgeoning population of immigrants who won't care a twig for all Browns bull !
So, what do those 'contingecy generators ' run on; clean hydro - generated electrical power? Or poluting Diesel Fuel ?..... A Pyrrhic Victory perhaps?

If anybody is interested, Singapore is supposedly not well-suited to wind power, with low-to-intermittent wind speeds (2 meters per second) where commercial turbines supposedly operate at 4.5 meters per second. Also the waters around Singapore are busy shipping lanes, so there supposedly aren't actually that many places to put the wind turbines.

Instead of supporting their neighbor country or providing neutral insights from technology view, they just went stamped whole nuclear power technology as bad and all Indonesians as incompentent developing country people from politics and conservative environmentalist views. Little did they know, Indonesia is going to harness the safe thorium nuclear energy commercially by 2028 according to the current blue print. The nuclear power plant will be built in Bangka Belitung area which is really short to Singapore. In that video, they also worshiped solar energy as an only viable option. They neglected the geothermal potential completely.

hello Jon at Asianometry,
I have been listening for a long while and, thank you. I have learned much and see some things differently. I enjoy your work, please, keep at it.
WOuld it not be simpler to generate hydrogen, tranport it in tankers and burn that for power generation?
it need to be continuous becuase i think the singapore will sell some of it to the malaysia and thailand.
Generating hydrogen uses 4x the energy that you get back out.
Cables flow 24/7. A 10% energy loss is acceptable.
Ships need diesel, lots of it.
Thank you for your effort in delivering such a good presentation! Allow me to point out a minor detail, in that ABB did not exist in 1954. ABB is the result of a merger of Swedish ASEA and Swiss Brown-Boveri companies much later in the twentieth century. Cheers!
Thankyou, as I did not know of the history of that merger, and had wondered why I never hear of those two parent companies anymore !

Wait that is sounds like indian word.. how about singalia.. hmmmm never mind..🥴🍷
The Asian Renewable Energy Hub (a different proposal to the Sun Cable) is suggesting something similar after they changing from their original submarine cable approach. Solar + wind farm in the Pilbara region of Western Australia to produce ammonia and ship that over for "green hydrogen". The Sun Cable company is pursuing the (much cooler in my opinion) HVDC approach. Right now it's all private investors betting on these renewable energy megaprojects, so it doesn't hurt you if their investments fail. I'm glad there are people with the capital and risk tolerance to invest in these really exciting solar farm and HVDC submarine cable approach! For the sake of our carbon dioxide levels I hope they succeed :)
Maybe in the future when Hydrogen can be generated, stored and used more efficiently. Right now the entire process is much, much less efficient that simply transmitting the power directly.
What would be a price difference for Australian solar to create Hydrogen and transport it to Singapoore, maybe using Plasma Kinetics storage method?
This is a very good video particularly in explaining HVDC high voltage direct current transmission which most people know nothing about I think.

@@roxyview Yes they are the sixth largest foreign capital investor in australia

Using compressed air most likely.
A good book on laying underwater cable is by John Steele Gordon, "A Thread Across The Ocean" on the first laying of the Atlantic telegraph cable, about 170 years ago. Same problems with cable and deep seas.
Indonesia has lots of geothermal electricity potential and it's way closer to Singapore than Australia. And geothermal runs constantly so no storage would be needed. Wouldn't that make more sense?
Indonesia is the 2nd biggest producer of geothermal energy. First and foremost thing we do is use all that energy for ourselves (275 millon of us).
Why would they not provide power to intermediate locations e.g. Timor or Indonesia? The cable could run on land across Java & Sumatra.
This is just speculation, but it could be because unlike Indonesia Singapore has almost no fossil fuel production of their own and already must import natural gas to provide for their electricity needs. Indonesia meanwhile is the world's fifth largest coal producer and eighth largest natural gas producer and can provide relative cheap domestic supplies of these fuels for their electricity needs. So there's a very different cost proposition in switching electricity sources between the two countries.
It might seem like adding intermediate access points would make sense even if the furthest points would still be the most economically attractive. But given this requires at a minimum additional conversion stations it comes at a high added cost.
Timor produces a fairly modest amount of natural gas but its electricity demand is a tiny fraction of what Singapore's is anyway so it's basically irrelevant.
@@espfusion looking at the expenses from this video. I would think it would be better for Singapore to build a nuclear power plant instead. Ample of long term power with lower cost than this project.

The big issue isn't transmission but storage. The video skims over nightfall. So what happens when the sun sets in Australia? Zero electricity traveling down the Sun cable. Singapore will still need power. Despite skimming over this, it is simply not possible to build any lithium battery large enough to cover for Singapore's nightfall sorry. Adelaide Australia installed the then world's largest battery in 2017 (Hornsdale Power Reserve). That battery can only power the city of Adelaide for 10 minutes. Singapore is 4 times the population of Singapore.
I stack my solar panels electrically to double the voltage and minimize transmission losses. Probably not making a huge difference even with my extra long coiled wire that needs to be trimmed to a reasonable length, but at least they kick on earlier and off later.

The map that was shown multiple times is incorrect, it shows the cable entering the sea in Kimberley region of Australia, which is a long way from Darwin. Compare with the correct map shown at 15:17
Yes, the line going through Darwin was in the wrong place, and so is the starting point (near the town of Elliot, NT). I have helped get this corrected for this video's thumbnail but unfortunately the video itself is already released and can't be changed.
Side note: there is/was another similar project called the "Asian Renewable Energy Hub" that wanted to build a submarine cable from a solar farm in the Pilbara, Western Australia. But they've switched to a plan involving using solar power to produce hydrogen/ammonia fuel and transporting the energy by cargo ships not electrical cables.
I think a bigger problem with AC, especially underwater, is that the cable forms a capacitor with the surroundings and thus there is an AC current to ground. The longer the cable, the bigger the capacitance, the higher the loss.
Excellent article but you didn’t mention how high the DC voltage is.
I believe that it’s around 1m volts. Is that correct?
Thanks.
12 volts. you will be able to jump start your car if you break down near it.
I'd guess for a cable that long you'd be very keen to minimise the amount of copper even if it means spending much more on ultrahigh voltage converters and switching gear. So you'd want it as high as technically feasible with those converters - currently 1.2M volts, though the limit is still slowly rising (largely driven by those massive Chinese projects).
Australia is the Saudi Arabia of solar power resource. Greater than Amazon in reducing CO2 emission.
The most informative video I've seen, examining assorted aspects of the proposal. Well done!
yes, it shows what a scam this project really is, well done!
Honestly, i am fully behind the idea of SG building its own nuclear plant. Let's just place it on one of the offshore islands near Indonesia :)

I read recently that solar panels are more efficient if they are cooled by floating on water. IF true, they might be better to make a closer floating farm.
Singapore is on a major shipping lane, it's not possible here
We have recently built the largest floating solar farms on our reservoir, and one on the straits of Johor.
Another one is being built in Batam and will generate energy for both Batam and Singapore.
And I don't know that it would survive the first typhoon ...
Sad facts.
-At best you get 10h (in summer) of usable solar energy per day.
-Battery storage is rubbish, only real storage is pumped hydro
-A problem mining companies have come up against when installing solar farms is dust. Basically to have to be constantly cleaning the panels out there. With even small dust layers dropping output 15-20%.
-Solar Cells are really only good (in a commercial sense for ~
Only 5-6MW of nuclear power for 10billion dollars?
25 years for solar panels.
Can't believe I just found this channel. Awesome topic
i like how the asean map shows singapore as batam
Or Darwin in Western Australia.
Makes more sense to go island hopping in Indonesia. Only need short stretches of submarine cable then.
That would be a lot more complicated both physically and politically
@@user5812 Still might be cheaper
Did the Australian government approve it though? Connecting cable from Australia to another maybe not allowed since the water is so deep and would be impossible to cover it in Australia deep water
Similar things have been done before. Submarine communications cable
@@guimauve522 it would cost a lot.
@@nathan-ck3je I didn't say it wouldn't I was just telling you that as you said that "since the water is so deep and would be impossible to cover it in Australia deep water"
Damn, that shark joke came outta nowhere and had me laughing out loud. Thanks for that 😃 and this excellent, informative video.
And the Platypus one :)
It is not a few rooftop solar panels. It is all over the island roof tops of public housing and solar panles floating on the reservoirs. Hope to reduce reliance on fossil fuel. In addition, SG pipe in low cost NPG from Indonesia. It is too costly to lay that Sun Cable from Australia..
The arbiter is definitely the best arbiter of arbitration.
Also I'm really enjoying your videos

@@MrMattumbo That's true but it required some Brute force
@@davidpendleton4464 I like my arbitors to work for their money, can't have them get lazy or they're no better than lawyers ;)
Bonus points when they decide your counterparty is a heretic and run an energy sword through their chest, best resolution ever!
can't argue with that verdict
any figures on what the power would cost in Singapore if the cable, farm and battery were built on budget? Probably need to add in more costs for backup gas generators for the inevitable power outages due to cable breakage. Looks like a pipe dream to me.
Australia is like a great big solar panel for South East Asia.
There is China and other countries near to Singapore and they will also compete... Otherwise just convert hydrogen from Africa/asia to electricity..
@@abrame8750 actually if you look even more closer than you'll know that there are a lot of other mines as well and they need to be developed.
@@arminius6506 I live in Western Australia, there's heaps of mines everywhere out in the country. nickel, bauxite, gold, lithium, iron... It's all being dug up and shipped overseas.
Like which other viable alternative is there?
TIME WE STOPPED THE BULLSHIT BEHIND WHY: The real reason behind this Singapore owns more of Australia than Australia www.crikey.com.au/2007/05/02/singapore-owns-more-of-australia-than-australia/
Here’s a list of Australian commercial assets controlled by the Singapore Government:
Optus: $10 billion
Alinta energy assets: $4.3 billion
Victorian electricity transmission monopoly: $2 billion
Old Texas Utilities Australian portfolio: $5.5 billion
Property: $2 billion
Australand stake: $1 billion
Total: $22.8 billion
The Singaporeans prefer to play down the scale of their Australian assets, but this little country of 4 million people has left us for dead when it comes to national savings and global investments. It will be interesting to hear what Peter Costello and John Howard say when the question is put to them about the Government’s residual commercial assets being less than those held by Singapore.
Electricity generated by solar panels will be dc current. So why the need for converters?
Singapore could become very dependent on this distant power supply, and if the cable is damaged, it could take months and millions of dollars to repair.
@@Bobspineable They can only get power from countries that have excess capacity and are willing to sell it to Singapore.
Probably because there is a lot they don't want Australians to know: TIME WE STOPPED THE BULLSHIT BEHIND WHY: The real reason behind this Singapore owns more of Australia than Australia www.crikey.com.au/2007/05/02/singapore-owns-more-of-australia-than-australia/

The losses on AC transmission through cables are much higher than the calculation here. Due to the physical proximity of the conductors in a sea cable, they have a very high capacity. A 4000km cable would have around 0,4mF capacitance, resulting in a reactance of around 10Ohms at 50Hz. Its basically a dead short. There is basically nothing arriving at the other end.
That looks crazy, aren't Indonesia and Malaysia much closer? Wouldn't it be easier to produce energy in, say, Borneo ? Maybe it couldn't be solar, but there would be other alternatives, no? Like, say, hydro or wind.
Indonesia doesn't have a desert to create a solar farm and their waterfalls are not that large to create a surplus of electricity. Also Indonesia is more population dense than Australia, so electricity surplus is harder. Australia has a lot of advantages, in addition to other political reasons. Also Indonesia might buy electricity from Australia this way. Note that the proposed route also intersects the places that Australia has major interest. Indonesia still have had to agree though*.
Edit: it's Singapore that hasn't permitted, not Indonesia
Indonesia and Malaysia are frenemies of Singapore. Friendship is conditional and transactional
We have trial to import energy from Malaysia.
www.channelnewsasia.com/news/singapore/singapore-importing-eletricity-malaysia-power-energy-13775308
Not one word from our government have been said of this. Other then mediaouts around the world tripping themselves making articles and interviewing the CEO, earning him free PR hype and potential investors.
It has been proven that deals strucked with Malaysia always run into problems. Look at the HSR project of late.
Too many trees need to be cut down for solar farms.
On another note. Yes Singapore would not have the land mass to implement solar panels but it is surrounded by water. Makes a lot more sense to develope tidal currents to develope power. The water is always moving
"A few rooftop solar panels on residential buildings. That is about it." - this statement is absurd. You certainly have not heard of Singapore's largest floating solar farm covering 45 football fields on our reservoir. It is also expected to reduce carbon emissions here by around 32 kilotonnes per year, the equivalent of removing 7,000 cars off Singapore's roads.
Only remove 7000 cars off the road, u also dare to cry father cry mother!!!
he is a foreigner. why dont you make videos instead and expect to know everything
The one that only generates 60MW? Haha...
'football fields on a reservoir ' sounds intriguing......
Could they run the power overland through Indonesia instead? Wouldn't that be a lot cheaper?
1 million VAC subsea is the way to go. It's been implemented onland from Moscow to Siberia in 1989. The challenge is subsea earthquake around Indonesia Island.
If I was a Singaporen investor, I would invest in Kalimantan Indonesia instead.
JD yours is the best suggestion so far.its cheaper,nearerncarries less risk.
Better HVDC. AC is not good for long underwear cables.
Others have suggested that too, I suggest checking out the video at 14:13 and comparing the amount of sunlight Kalimantan receives compared to Australia, then Googling "Kalimantan weather report". To talk the investors out of building that undersea cable you have to convince them it is more expensive than building the solar farms five or more times bigger to produce close to same amount of energy.
Earthquakes _might_ damage the cables, daily tropical storms _will_ cause problems for solar and wind power. Maybe they should look into geothermal and tidal energy instead.
1. Subsea cables cross tectonic boundaries all over the world.
2. And put the rainforests in Kalimantan at further risks when they are already in great danger? No way.
@@huaiwei Oh yes, that too. Australian Outback can easily fit these huge solar farms and the local environment would probably thrive with the shade they give. On Kalimantan you not only have to cut down the forest, but because the tropical weather reduces the amount of available light you actually need to build at least two farms to match the one proposed for Australia, meaning more forest needs to be cleared...
But it gets better, as just about only way to calm down the people who would protest this project is to promote how it produces clean energy... Oh, wait...
So next you would have to cut down even more rainforest to build more solar farms so the locals can get clean solar power too.
Also, cutting down rainforests tends to cause erosion so the solar farms might get washed away by floods or destroyed by a landslide.
1. Damage to undersea cables is hopefullly very rare but is always difficult to repair..Was that the Basslink problem?
2. The reason for transporting the energy from Australia is that Australia has lots of solar-exposed space. I wonder how much investigation has gone int finding solar resource closer to Singapore. Offshore perhaps.
That's a whole lot of work and money for only providing 20% of Singapore's power needs.
Singapore has reportedly passed a law that no single source can provide more than 25% of Singapore's electricity. That spread your risk approach seems to be how they approach international relations. They try to make sure their economy and security is not overly dependent on either the United States or China. Whether they are getting the balance right can be debated, but that's their strategy.
@@shazmosushi why not build a nuclear power plant instead of relying to power import?
@@UltimateAlgorithm Traditionally , no one wants a nuclear power plant in their "backyard" and all of Singapore would be the backyard . Secondary issue is : Where do you store the nuclear waste , some of which will be deadly for ten thousand years ? That would most likely require an international agreement for not only a remote storage location, but the rights to shipping it by cargo ship . Cost to benefit ratio kicks in .
way and way more money, if you think there's no politics friction between Indonesia and Singapore while the lands are neighbor for million of years, you gotta be kidding
@@biketech60 I mean so little space so much power needed, density requirement kicks in. Solar and wind are some of the least dense power available. Nuclear on the other hand is very dense in terms of space to power generated ratio. For the waste, just drill deep down. Create an underground storage space 500 meters or more beneath the surface.
Why does the cable need to run fully undersea and not island hop between Australia and Singapore?
Considering that Australia is basically the prime source for uranium in the world, it would’ve made a lot more sense for Singapore to invest in small modular reactors instead.
Where are they? A bit like fusion power, pie-in-the-sky !
I lived in Singapore many year ago, during that time, many private residences were being built. If each of these private residences were fitted with a 10 kilowatt solar system feeding into the grid, they would not be in the dire straights with electricity they are. Moreover, going down that road, they are not reliant on anyone else and cannot be held to ransome. Reports I have read suggest power from this proposed solar farm in Australia would be used to manufacture hydrogen which can then be exported and used for varius uses.
How many of those residences have 50sqm of suitable roof for the 10kw of solar?
This would be interesting on how to transmit electricity over such a long distance without losing too much power along the way.
Easy increase volts
HVDC as explained in the video.
What's Australia's total amount of platypus export per annum?
Japan is working on a similar project, but the electricity generated in Oz is first converted to Hydrogen, then compressed, and shipped to Japan. There the procedure is reversed to supply electricity.
I wonder how Australian folks feel about the potential destruction of their homeland over these types of projects. A quote I learned years ago definitely applies to these types of projects: "The Law of Unintended Consequences."
Not sure how that differs from mining sites, given these solar panels are built in very remote and desert areas; away from cities.
@@MsEverAfterings Exactly, while not all of them are remote as the one in the video, most are in the middle of nowhere and are usually built on depleted and nonviable ex farming land for the ones somewhat near population. Nearly all the big ones are out in the middle of whoop whoop. My friend has worked on a number of these solar farms in Aus and most are literally nowhere on inhabitable land.
Have you ever been to Australia? Obviously not; if you had you would know that there is a whole lot of nothing outback with no people and thousands of square kilometers of semi-desert ! If anything, those solar panels will provide shade and moisture for a little more life to form/colonise the area !
How could Indonesia is okay with this long cable passing through the country without getting any direct benefits?
Importantly, Australia is politically stable and has a long history of supporting Singapore thought it's history. Importantly, support for Indonesia, has always been strong.
LoL
@@hull4bal00 Australia is politically stable mostly
Its more stable then a lot of countries
@@TylerMarkRichardson "Australia support for Indonesia has always been strong"
That part make me laugh 😂
Very informative video. Thanks so much for sharing! ❤❤❤
Check out New Zealand cook straight lines. Deep and in high current speed area like Bass Straight
I'm surprised that the battery backup proposed is for onsite with the panels. I would think you'd have the panels feeding battery backups onsite with your use end point (Darwin, and in Singapore) . That way you are using your batter storage after transmission losses, rather than before, so you need less total battery. It seems like if your batteries are housed with the panels, some percentage pf your battery bank exists solely to be lost in transit.
Just personal thoughts but by storing at the production end: 1/The most expensive part of the total system (the cables) can be built thiner since they just gonna have to be sized for day or night consumption and not in proportion of the peak production moments (when the sun shines at max in Australia). 2/ By retaining power on the production side, the proportion of losses along the transport will also be lower since the intensity will also be lower 3/The investor has a better control on the electricity price since it can release power at peak price moments (at this scale of energy, prices per GWh can almost double in a matter of hours) and improve its profitability. 4/They could maybe count on low cost/low density battery technonolgies that seem to be currently under development taking advantage of the australian desert abundance of space.
omg that is a major project great update !
I am surprised Singapore sovereign funds are not involved in this, needing private seed monies. Is 3 GWatt is about 25 Terawatt hours in 1 year? That will be half of Singapore's yearly power consumption.
I'm surprised one of Australia's retirement funds (the "superannuation" system) hasn't invested in it, with trillions under management hungry for long-term infrastructure projects. But I guess the project might be too high risk right now. I'm sure they'll invest eventually.
That because it all hype by the CEO, no relevant SG government agencies have acknowledged it, we sooner buy energy from Malaysia.

8TWh. Solar only gets about 33%.
12:30 Basslink - It wasn't our fault!
Hydro Tasmania: Were it so easy
Make.you wonder that's why hydro Tasmania sent a guy to Sarawak for this 20 dams they plan to build. Seems easier to build a massive cable than using illegally run govenrment to build massive dams
Your diagram at 1:42 misses Darwin by as little as 1000km.
Hi! Could you make a video about the malaysia-singapore failed high speed rail project?
Last time I heard it got restarted.
@@UltimateAlgorithm No, it didn't get started. Msia insist on using their crony companies to run the show whereas Spore insisted on a neutral 3rd party instead, which has always been a crucial part of the agreement. That is why Msia is willing to compensate Spore for breaking the agreement... because the fault is so clear cut.
@Munish this is Singapore and Malaysia we are talking, they are much more capable than Sri Lanka and other countries that got trapped by China.
@@marktan8074 I heard both Singapore & Malaysia agreed with China to build the high speed line. Does not matter who build it, I think it will be good to have high speed connection between the two countries. I hope that Indonesia joins and continues the line to Batam though. Probably not gonna happen, but one can dream about it, hahaha.
@@marktan8074 Well the supposedly 'neutral' 3rd party want a 6% government guranteed interest for their investment (can't really called it an investment really as it is gov guranteed income). At that point it kinda meh considering japan is offering 1% or china 4% rates on loan.
Also MY want to change the scope to reduce cost by utilizing the existing airport link like TH is doing. But doing so reduce the attractiveness of the project to both JP & Ch as the airport link utilize european standard. Ch doesn't have a narrow HSR trainsets to sells & JP narrow HSR train are a bit too short, this mean SK & EU firms has a better product to sell.
Another potential change is that MY possibly want to follow in TH footsteps and just privatize the whole thing to a buddy buddy companies in exchange for land for transit oriented development to reduce the government debt burden.
As for SG, the whole changes is too far different from the original agreement and thus they wanted a new agreement instead.
Am I missing something? How much electricity does Singapore actually need? Wouldn't it be cheaper to install a bunch of solar panels and wind turbines on their high rise buildings in combination with offshore energy generation tech closer to singapore? Also is thermal energy not feasible there?
Dude why are your videos so good, jesus
Why can't they run the line over land when you get into the islands the rest of the way to the destination? And have a small solar farm to step up the power.
Very interesting report.
In Sweden the government
is realizing the big electrification by windmills all over the country and especially in the north.
Beside destroying ”the last wilderness of Europe” it needs huge powertransmission to the south and to the European grid.
We now know that sun and wind cannot save us due to the needed backup when wind and sun low - cold and dark winter neither works. The EU had forecasted 90.000 windmills around the Baltic Sea in their latest. Technical Report. Global players backing investments in “green tech” and generate a political fear in climate crisis. Lobbying/corruption.
Renewables are not fossilefree if you study their lifecycle demand mining, manufacturing, installation and decomissioning.
So why not use the small modular nuclear plants derived from the many hundreds you find in military vessels. They can consume old nuclear waste - no mining, compact in space,
prefabrication, easy transport, safe cooling with air convection, placed where needed, heat for heating/cooling/desalination/waste
Ideal for Singapore and others.
Please do a video about this
Kind regards Torbjorn Sjodin, Sweden
Your maps are drawn wrong. Darwin is on the "middle hump" of northern Australia. You keep showing the cable coming from the "left hump" near Wyndham in Western Australia's Kimberley region.
Hopefully they prepare they cable route with a massive amount of overhead for future powerdemand. Solarpower for all of southeast Asia FTW 🙂
Plenty of room in the sea for more cables. Laying more cables, as needed, would devlop the benefit of redundancy.
@@21stcenturyfossil7 Maybe they should lay two at once while they have the ship and all the gear there doing it !
I thought skin effect only comes into play at either higher frequencies, or else at very thick cables. I would have thought stray inductance and capacitance would be the main parasitics in electricity transmission? I'm no expert though.
Electrical Engineer here. You are indeed correct. The Skin effect contributes to additional losses but is quite low in 50 Hz or 60 Hz systems. The main reason for these losses are parasitic inductive and capacitive effects on long transmission lines. Not to math it out to much but for each delta x (change in distance or length of the cable) there is a delta L (change in inductance in case of rising x it's an increase) and a delta C (change in capacitance)
They couldn’t afford the price of Australian electricity - most Australians can’t.
