As far as I can see, the answer is negative. The shortage of electricity this time is believed to result from two factors. On the one hand, the price of coal has increased a lot recently, but the electricity price is only allowed to float by at most 10%. Power generation is now a money-losing business. As a result, there is no motivation for power plants to produce more electricity. On the other hand, the goverment wants to achieve carbon neutrality by 2060, so local goverments at all levels are assigned some KPIs. Because of the return of manufacturing caused by COVID-19 in the first half of the year, many places used up their entire year's worth of emission credits early, so they had to forcibly cut off production.
