Ultrahochspannung: Eine Hochleistungs-Stromübertragungstechnologie. Es sendet große Energiemengen über sehr große Entfernungen mit sehr geringer Energieverschwendung.
Das Netzwerk hat sich in fünf Jahren fast verdoppelt und ist von 39.000 km im Jahr 2020 auf 62.000 km (ca. 38.500 Meilen) im Jahr 2025 gewachsen. Diese "Stromautobahnen" Wind-, Solar- und Wasserkraft aus der Wüste Gobi und dem westlichen Hochland in den Osten leiten.
Die Kapazität: Eine einzelne UHV-Leitung hat eine Leistungskapazität von 8–12 GW, was dreimal so viel ist wie die stärkste Backbone-Stromleitung PDCI in den USA

🇨🇳China is paving the way to our glorious future. 🇨🇳
“with clean energy from Western China” would have been more clear.
“the West” typically refers to the western hemisphere.
Meanwhile Trump is paying people not to build wind farms.
Our country is a fucking joke
What is your excuse other countries?
China is the type of country to just get shit done. These projects don’t have to go through the same bullshit bureaucracy and approvals as many other countries. That probably comes with a firm government hand though
As much as I love these Chinese for never stopping advancing, the fact they prefer UHV over HV systems isn’t really a major deal. They have high power generation concentration and their political system means they can build substations at will and don’t have to fight zoning regulations to do so. And HV systems work just as well, and make more sense when consumption is well distributed among medium-sized population centers, like the US.
Another thing is that this kind of distribution is a very delicated affair, with very little things you can play around with. Like, it’s cool that they’re building, but it’s not any huge innovation. So much so that the Chinese sent delegates to Brazil (a leader in the sector because you need UHV to deal with Hydroelectric power) in the 70’s to learn how to build UHV, and State Grid still uses the same construction methods and technology, with a lot more smart control, obviously, in these new UHV lines. That is to say that the only significant advancement in this technology will be the invention of the room-temperature superconductor, and until then we’ll just be building more. Like the Fibre-Optic cable.
Anyway, and corroborating with my last point, the last information is also untruthful. The highest AC distribution voltage in China is 1000kV, while in the US it’s 765kV. So it’s not 3x. More like 1.2x when the voltage is actually at a maximum. The Chinese operate 1100kV DC and the Americans 1000kV DC aswell. That’s because this tech is pretty much the best it can be right now. If anybody wants to try building, I don’t know, 10 MV, the ionised air will spark and a lot of stuff will start to fry.
Again, the maps are cool and it’s cool that they’re building it, but let’s not make it about Chinese exceptionalism in tech like the description implies. If anything, it’s their exceptionalism in building this stuff so fast.
Taking advantage of all the solar energy generated in the Xinjiang deserts
galicia’s economy has historically been less industrialized compared to other regions in spain
But I’ve been told that they just build coal plants so it doesn’t make sense to get rid of fossil dependency here either
Germany still doesnt have the necessary lines from North to South because of incompetent politicians, NIMBYS and boomers
I appreciate the post but I want to correct several moments. Currently in the western part of china there is a huge capacity of coal power plants operating next to the wind and solar so while that might be temporary I think it’s important to remember that currently the energy from there is not that clean.
Another thing you missed is that that these are no ordinary ultra high voltage power lines. They are DC, which allows them to be much more efficient at very long distanses. Very useful and interesting resource is https://openinframap.org .
Why und How does China seem to have endless money?
