Osaka- Less than a month before the opening of the Tokyo Olympics, attention is focused on the available electricity supply and the amount consumers pay for electricity during the hottest months of the year.
However, while previous government quotes warned of tight demand, industry groups, including utilities and retailers, provided revised quotes that did not show a less dire situation, especially in July. did.
Kazuhiro Ikebe, Chairman of the Federation of Electric Power Companies of Japan, said, “We hope that we can secure a stable power supply without worrying, especially in the event of an unplanned power outage or various problems.”
Under national electricity law, utilities must maintain a minimum reserve requirement of 3% of maximum demand as a safety measure against sudden shortages. If the reserve ratio falls below 3%, power cannot be supplied when the maximum demand is reached, and there is a risk of rolling blackouts. Power companies generally reserve a reserve of 7% to 8% or more to prevent power plant troubles from reducing supply capacity and increasing demand due to high temperatures in the summer.
At the end of May, 8 out of 10 major Japanese electric power companies are expected to watch the Tokyo Olympics and the baseball tournament where I go to Koshien with air conditioners, 3.7% in July and 3.8% in August. I predicted that it would be a reserve rate. House. Kyushu Electric Power also predicted that the reserve requirement ratio in July was 3.7%, but it is forecast to rise to 6.8% in August.
The Ministry of Economy, Trade and Industry (METI) said the low forecast in late May was due to a decline in supply capacity due to the shutdown or closure of 10 old thermal power plants, including four operated by TEPCO. Electric power company Holdings (Tokyo Electric Power) operated by Kansai Electric Power (Kepco) and Tohoku Electric Power, and electric power company Holdings owned by Chubu Electric Power and Kyushu Electric Power respectively. The government has predicted that summer electricity demand will be the toughest since 2017.
However, on June 18, a more optimistic view came from the interregional coordination of transmission operators, a group of transmission and retail companies. KEPCO’s Mihama No. 3 reactor has already restarted, the Oi No. 3 nuclear power plant will be restarted by next month, and the two thermal neutron reactors in Tohoku and Shikoku are expected to return online soon. There is. It is available in Honshu, Shikoku and Kyushu than the Ministry of Economy, Trade and Industry predicted last month. However, some areas such as Tokyo and Tohoku will still face tensions in August.
The reserve requirement ratio for July from Tohoku to Kyushu is expected to be 5% to 6.2%. The ratio in the Tohoku / Tokyo area in August is expected to drop to 3.9%, while the ratio in central and western Japan is expected to rise from 6.1% to 6.5%.
Only Hokkaido and Okinawa were expected to have enough electricity to meet the demand. According to two estimates, the reserve rate of Hokkaido Electric Power is expected to be 16.2% in July and 23.9% in August, and the reserve rate of Okinawa Electric Power is expected to be 29.9% and 31.6% in July. August.
Consumers may be considering higher energy prices, regardless of the difference between utilities and retailers in how much electricity usage in July and August approaches the required reserves. In the simulation model of TEPCO’s household electricity bill, the average monthly bill in January is 6,317 yen. It is projected to rise by more than 600 yen to 6,973 yen by next month. This rise is due to crude oil prices, which were expected to continue rising until August.
Chief Cabinet Secretary Katsunobu Kato said at the end of last month, “It is difficult to continue your usual life, such as using an air conditioner, so please turn off the lights in the unused room and use it efficiently.”
