Electricity supply and demand this summer was expected to be the tightest in many regions in recent years, but is expected to improve with the restart of nuclear power plants and the restoration of shut down thermal power plants.
The OCCTO, which regulates the supply and demand of electricity nationwide, has so far estimated the supply and demand of electricity this summer as a reserve rate that indicates the surplus capacity of electricity supply in Honshu, Shikoku, and Kyushu, assuming a heat wave of about once every 10 years. Was expected to increase from 3.7% to 3.8%.
Although it exceeds the minimum required of 3% for stable supply, it has been considered to be the toughest in recent years.
However, in addition to Kansai Electric Power, Mihamagenpatsu Unit 3 located in Fukui Prefecture was supposed to be re-activated during this month, supply from such that the prospect of recovery was standing on was stopped at the trouble Shikoku and Tohoku of thermal power plants The power is expected to increase.
As a result, the reserve margin for this summer, which reflects the latest situation, is expected to improve from the 5% level to the 6% level in Honshu, Shikoku, and Kyushu in July.
In August, TEPCO's jurisdiction and Tohoku Electric Power's jurisdiction will improve slightly to 3.9%, but other regions of Honshu and Shikoku are expected to rise to the 6% level, and Kyushu to the 8% level.
Although the supply and demand of electric power is expected to improve this summer, electric power companies will continue to make every effort to secure a stable supply.
