Affected by the cooling in Japan's Kanto region and the power supply shortage of Tokyo Electric Power Company (TEPCO), the Japanese government issued a power supply shortage alarm on the 21st, calling on users within the jurisdiction of TEPCO to save electricity. According to Japanese media reports, Japan's Kanto region is expected to have snow and rain on the 22nd, and the heating demand of residents and enterprises may increase. The strong earthquake off the coast of Fukushima Prefecture on the 16th has damaged and shut down the No. 6 unit of Dongdian's Guangye thermal power plant in the county. The Japanese government expects that the remaining power supply capacity, namely "power reserve rate", of 8 counties in Dongdian District, including Tokyo, may be significantly lower than the minimum to maintain a stable power supply. Once the power supply cannot be ensured, it may lead to large-scale power outage. To this end, the Japanese government issued a warning of tight power supply, calling on families and enterprises in the jurisdiction of TEPCO to save electricity from 8:00 to 23:00 local time on the 22nd. Dongdian said that on the 22nd, the company will do its best to ensure power supply. As it will take some time for the power plants damaged and shut down in the earthquake to resume power generation, the shortage of power supply will continue in the short term. (Xinhua News Agency)
