alt Hacker NewsChina has the most sophisticated grid in the world, and is spending $100B a year on expanding and upgrading. They have a uniquely high share generated by renewables. It runs 800kV and will go higher after the upgrade. The first Small Modular Reactor will come online this year. If you think that’s all just being built in random factories without standards you’re very much mistaken.
China's energy generation mix is not uniquely high in renewables! Where on earth did you get that idea from? China has about the same % renewable generation as Australia, about 1/3rd. Brazil has 80%, Norway 90%, some have near 100%.
What China does have is a very high carbon emission intensity of electricity generation thanks to over half capacity coming from coal.
