As I read the (excellent) article, I noticed that there's quite a bit of dissention regarding the overall design of what they're building out. "power engineers are struggling to master the resulting hybrid AC-DC transmission system.... What has blocked full implementation is an intense debate over the future of UHV ... State Grid’s monopolization ... the centralization of grid planning and operation that UHV requires.... unifying China’s grid would make it far more vulnerable to cascading blackouts..." Probably we, on a smaller scale, should have been doing something like this at least 10 years ago. OTOH, China is pushing the envelope ... and when we finally decide to get off the dime, we'll know better what works. So far (I think), we don't have any cities like Shanghai that run 'short of power for several weeks each summer'.
