World's Largest Solar Farm Goes Online In China 87

Posted by BeauHD from the flip-the-switch dept.
Michelle Lewis reports via Electrek: The world's largest solar farm, in the desert in northwestern Xinjiang, is now connected to China's grid. The 3.5-gigawatt (GW), 33,000-acre solar farm is outside Urumqi, Xinjiang's capital. The state asset regulator's website cited the Power Construction Corp of China and said it came online on Monday. The solar farm will generate about 6.09 billion kilowatt hours (kWh) of electricity annually. Assuming an EV consumes about 3,000 kWh per year, 6.09 billion kWh could power 2.03 million EVs annually.

The world's largest solar farm in Xinjiang is part of China's megabase project, a plan to install 455 GW of wind and solar. The megabase projects are sited in sparsely populated, resource-rich areas and send their generated energy to major urban centers, such as on China's eastern seaboard. China now boasts the three largest solar farms in the world by capacity. The Ningxia Tenggeli and Golmud Wutumeiren solar farms, each with a capacity of 3 MW, are already online.

    Ah yes I remember hearing America could be powered by a few solar farms in the deserts. But certain people demanded that idea be shoved where the sun don't shine. Now we get to watch China beating US at solar (and perhaps a few other things too).

      A single reactor produces more energy, comfortably sits on a thousandth of the area, and lasts the better part of a century. China is winning because they are building many reactors and developing much more efficient ones, based on the MSR technology we gifted to them. Their resource efficiency can be expected to grow by orders of magnitude, and will also be used to produce cheap synthetic fuels and such.

      Winning does not look like replacing each of our hundred or so reactors with >100,000 acres of solar

          Two of them are misleading anyway.

          "Uses less land" ignores the type of land required. Nuclear needs geologically stable land, close to a source of water for cooling, but away from large population centres in case of an accident. It also needs mines to supply fuel, and more mines to store spent fuel for extremely long periods of time, again in geologically stable areas.

          "Lasts longer" is debatable. Solar panels appear to have a lifetime similar to the design lifetime of nuclear plants, but crucially they are

                It’s a conflation of two different meanings of the word “need”. Nuclear plants “need”, ie absolutely must have, land that’s geologically stable, with a water source for cooling etc. Solar “needs”, ie works best, with land that’s got high insolation and few things dropping on it. But *it still works* even if the land isn’t great in one way or another, as you pointed out. Whereas nuclear doesn’t work if the land isn’t good enough.

      • Solar has the advantage of being sorta portable. You don't need huge installations of panels. Think of how much area is available on rooftops. Including panels on top of every roof that presents to the sun correctly would supply a substantial chunk of power to the grid. Producing locally would also have the benefit of reducing the loss trough transmission. This would not produce all of the power needed. There would always be a need for power plants of one kind or another.

          OTOH, rooftop solar has the advantage that any energy converted to electricity won't inadvertently heat the house. But it has the disadvantage that installing or maintaining it is a bit dangerous.

          Perhaps it could be installed as a "cooling shade" roof over highways through the deserts. This would allow easy access for any needed maintenance, and the land is already state property.

          You left out maintenance. Both require maintenance, but nuclear requires a lot more.

          There are always trade-offs though. Nuclear is better at providing a stable amount of power over a long period of time. Solar tends to fluctuate. (And not just on an daytime/nighttime basis.)

      • Except the solar plant can be built much faster as a reactor can, and does have zero safetyproblems. So until those reactors are all build the solar plant is delivering a lot of needed energy. But you're certainly right about the real estate it requires to deliver the power, a reactor is much more convenient. But it is very nice to have an alternative in the meantime.

          China will drive US manufacturing out of business if it ends up being powered by renewables and solar. There is demand for low carbon products, and taxes on carbon emissions which include those from overseas manufacturing.

          If the US doesn't clean up then it will give China another way to out-compete it. Same goes for Europe and everywhere else.

It appears to me that it is quite a bit but that doesn't make the same kind of news for some reason. There's a lot of mainstream news from China on their successes to build out solar power but not so much on hydro and nuclear. If China is doing so well on moving away from fossil fuels then we need to see the entire picture.

    The new 1100-kv UHVDC line absorbs the grid’s alternating current at an AC/DC converter station near the capitol of Xinjiang—China's vast northwestern territory—and sends DC power to a second converter station in Anhui province in eastern China. That 3,293 kilometer run extends power transmission’s distance record by over 900 kms.
