UHVDC is progress is "fine", I think utilization is 60-70%, ideally it would be 80-90% but hurdles now mostly political, many central govs still want to prop up local coal, so new policies on national unified electric / spot market by 2026. Current UHVDC capacity is ~150GW, utilization around ~100GW, PRC peak demand ~1000GW, i.e. UHVDC transmitting like 10% national power, could be 15%. Rollout for next 10 years is to hit ~25%, something like 300GW (70-80% from western renewables), assuming peak power demand grows to peak 1200-1500GW. But this is based on outdated 14th 5-year plan projections (~2021), PRC currently on trend to 1800-2000GW peak. Don't know if there's new policies to scale UHVCD accordingly.
