The government issued the first "electric power supply and demand tight warning" in the jurisdiction of Tohoku Electric Power in addition to the jurisdiction of TEPCO, saying that the power supply and demand situation on the 22nd is extremely severe.
We encourage homes and businesses to help save as much electricity as possible.
This is a commentary by Odashima, a reporter from the Ministry of Economic Affairs, on how tight the supply and demand of electricity is and what kind of power savings can be achieved at homes and businesses.

According to the people concerned, the supply and demand of electricity on a tightrope is extremely dangerous and serious in the TEPCO and Tohoku Electric Power jurisdictions.
This is the "usage rate" that indicates the ratio of demand to the power supply capacity.
It shows the severity and tightness of the TEPCO jurisdiction.
It was 86% at 7am, 97% at 9am, and 101% at 10am.
On the data, the actual demand for electricity exceeds the supply capacity.
Since the supply capacity is urgently increased and there is a time lag, it seems that it does not actually exceed 100%, but according to TEPCO, it is close to 100%.
Within the Tohoku Electric Power jurisdiction, the actual result at 10 am is 99%.
The 11 o'clock level will be announced shortly, but even recently, electricity consumption has remained at a high level.
In any case, it is a very unusual and serious situation that the nation's first electric power warning is issued.
Future outlook
In order to meet this harsh supply and demand from the morning, TEPCO has been operating a power plant that pumps up water to generate electricity, but there is a risk that it will be used up in the morning due to increasing demand.
In addition, although TEPCO receives power interchange from Tohoku Electric Power, it is facing a very difficult response due to the tight power consumption within the jurisdiction of Tohoku Electric Power.
If further power saving is not promoted among households and businesses, demand will greatly exceed supply capacity, and in the worst case, a large-scale power outage may occur.
what we can do
What we can do is
▽ heat up in one place as much as possible so as not to turn on the heating in different rooms at home, ▽
always turn off the lights and heating of the unused room,
▽ even when turning on the heating
It is also effective to set the temperature to 20 degrees without raising it too much.
Further cooperation to save electricity is essential to prevent power outages.
