Visitors who visited Gyeongbokgung on the 22nd after the heat of the day have cooled in the shade. KHNP said on March 22: "We will try to revive Hanvit 3 and Hanul 2 in suspension before the peak period (August 2 to 3). He also decided to adjust the scheduled preventive maintenance start of Hanlight 1 and Hanle 1 after the peak power period. The scheduled preventive maintenance of Hanvit 1 and Hanul 1 was initially scheduled for 18 and 29 next month respectively. Hanool 4, which has recently completed preventive maintenance, resumed operation from the 20th. It is expected to reach 100% output on 24. Jung Jae-hoon, chairman of KHNP, said: "With this, a total of five nuclear reactors and 5 million kW of additional energy will be available in the period of Power peak. "

Baek Woon-kyu, Minister of Commerce, Industry and Energy, also carried out an emergency site inspection. Baek visited the Korean Tundo substation in Gwangjin-gu, Seoul and other neighboring apartments, along with KEPCO President Kim Jong-bok. "We will be able to provide a stable electricity as generators supply will be increased and emergency resources become available, "Baek said, adding that" we will strengthen management to avoid inconvenience such as power outages.

Initially, the government repeatedly pointed out that there would be no problem with electricity supply this summer. On August 20, 2008, while the summer electricity demand was 8,880,000 kW, the ratio of supply to demand is stable, with a ratio of supply reserves of more than of 11%. In the normal industry, if the ratio of supply reserves is greater than 10%, there is no problem of supply and demand of electricity. However, the demand for electric power has exceeded the peak of 2016, which was four times higher than last week. It is expected that the heat wave will continue for some time, and he seems to have prepared a countermeasure quickly. An official from the Ministry of Industry said: "This week will be the biggest obstacle to demand before the holidays."

After the government has changed the maintenance plan for nuclear power plants, some people point out that it will artificially increase the operation of nuclear power plants to increase supply. However, there is no context in which KHNP escalates or forcibly reverses the preventive maintenance period. On May 11, Hanbit 3, which started the preventive maintenance project, originally planned to complete maintenance on August 9th. Hanool 2 also completed maintenance on May 10th. However, the repair work was stopped abruptly during the last 12 days, and the big problem was not found, and it was not until the restart.

An official from the Ministry of Industry said: "The long-term plan to convert energy conversion policy such as nuclear power plants into an environmentally friendly energy mix is ​​not intended to stop nuclear power plants. "He said.

However, it is hard to avoid criticism of declaring a nuclear power plant and finally looking into the nuclear power plant when it is difficult. According to the "summer summer demand and supply measures" announced by the government on May 5, the peak demand for electricity this summer was 88.3 million kW, which was forecast for the second and third week of August. However, the prospects have already been missed. It is not right and wrong to pretend that there is no problem with a nuclear power plant project that excludes nuclear power plants, without forecasting the demand for a season. This is why it is stated that it is necessary to have the nuclear power plant and confirm that the nuclear power plant is indispensable.

The government is currently working on a demand reduction (DR) card. DR is a system that the government compensates when companies reduce their electricity consumption during peak hours. Currently, companies participating in R & D can reduce demand up to 4 million kilowatts if they meet demand. The Ministry of Industry released two DR last summer. DR is emitted when the reserve power falls below 10 million kW and demand is expected to exceed 88.3 million kW. Over the last 20 days, reserve capacity was 9.22 million kilowatts and demand was 88.8 million kilowatts. If the demand increases a little more this week, the standard will be respected.

But the worries of the industry are deep. Since the declaration of the government's nuclear power plant, DR has been criticized for transferring power shortages to companies. In fact, the benefits are not great. Even if you issue a DR, not all companies participate in it. The reduction in actual demand is about 500,000 kW. The reserve requirement ratio is less than 1%. If the ratio of supply reserves does not fall to a single figure, it is the service of the industry that does not want to remove the card as much as possible. "The demand management policy has been turned upside down by the sudden breakdown of nuclear energy by the government," said an electrical engineering professor who wanted to remain anonymous.
