"...1-8月份，原煤和原油产量同比分别增长4.4%和2.4%，发电量增长11.3%..."

This bloomberg analysis is more balanced:https://youtu.be/N1FM3dkNOu0

Likely some local govs didn't distribute the powwercut more rationally, say didn't cut power feeding certain lo value added hi energy intensity xport orientated industry

An usual practice of negative propaganda is to take negative exceptions as norm like this hindu site:

Some basic fact eggs people here could throw at other sites:

China produced 3.9 billion tons and imported about 300 million tons of coal in 2020. Coal freight cost by train is more expensive than ship freight, so some coastal cities import coal.

Chinese electricity production/capita is about 40-45% of yanks', however it's within the range of west euro figures.

(Hindus produced around 730 millions tons https://coal.gov.in/major-statistics/production-and-supplies &imported 200-230 million tons; hindus coal are mostly of poor quality and import most of their metallurgical coal)

Here's a good indicator: http://zzwave.com/plaboard/posts/3964134.shtml

Why electric power cut?

1)CO2 cutting target

2)(Short term)Covid related price disturbance like energy price jumps,10 folds increase in container shipping costs...

3)Tell the yanks to buy lo-value added but hi energy intensity stuff elsewhere.China wants to upscale the economy.

4)China isn't going to subsidize internal yank comsumption any longer. To hell with their lifting debt ceiling
