According to TEPCO, the "usage rate", which indicates the ratio of demand to the power supply capacity in the jurisdiction, was 94% from 9:30 am to 10:00 am.
On the 28th, from 3:00 pm to 6:00 pm, especially from 4:00 pm to 5:00 pm, the power supply and demand is severe, and the government is enthusiastic about continuing the "power supply and demand tight warning" within the jurisdiction of TEPCO. We are wary of illness and seek to save as much power as possible while using cooling properly.
