Counteroffensives of nature are going on. The melting speed of glaciers in the Antarctic and the Arctic is getting accelerated, and it is reportedly predicted that sea level will go up by about 1 meter by 2100.
Warnings were issued that large cities which are located on coasts around the world, such as Shanghai and New York, will be sunk under water. Many people are concerned over gloomy future of the earth as they experience a large number of unusual signs every year, such as abnormal temperature and super strong typhoons. And we empathize with them. This is the reason why we are taking part in the global endeavor of reducing carbon dioxide, enduring social costs.
There was a man named Heinrich who laid a milestone in preventing industrial accidents by systematically analyzing a series of unusual symptoms.
He was taking charge of engineering and loss statistics at Travelers Insurance Company in the United States around 1930. While analyzing numerous accident statistics, he found a general law.
He found that the number of slightly injured workers was 29 and number of potentially injured workers was 300 before a worker was seriously wounded in industrial accidents.
This is called the law of 1:29:300 of Heinrich. The key point of this law is that we can prevent serious accidents if we grasp and remove causes of abnormal signs in early stages.
We reflect that the rotational power outage made on September 15, 2011 might have been resulted from overlooking signals of abnormal symptoms, such as irregular temperature, excessive errors in demand prediction, negligence in correction effort, and insufficient examination on available electric supply reserve capacity. The rotational power outage was evaluated to be an inevitable choice to prevent more serious damages, and yet it is remembered as a day that makes us think again about overall matters of electric power industry, including practices and institutions.
After that day, Korea Power Exchange (KPX, Chairman: Nam Ho-ki) adopted the motto of ‘365-1=0’ as a core value in operating electric power systems. This emphasizes that operation of power systems cannot be recognized when it fails in operation even for a day in 365 days of a year. It implicitly expresses its will to permit no mistake by analyzing and grasping abnormal signs in advance.
At present, critical situation of electric power continues where demand and supply reserve level shows imbalance. Moreover, numerous abnormal symptom factors that negatively affect power supply and demand still remained unsettled. They are continued increase of conversion demand and power loads in industry due to low electric charges, aggravated shortage in transmission routes and power plant sites due to regional NIMBY phenomenon, malfunction in removing social conflicts, insufficient procedures for proper compensation systems and collecting public opinions, deficient publicity on electromagnetic waves, and insufficiency in forming consensus.
During this summer, electric power authorities issued 4 level-two warnings (power reserves of lower than 4 million kW, and momentary lowest reserves of 3.2 million kW), and 28 level-one warnings (lower than 5 million kW).
We could have experienced critical moments if several power generation facilities developed troubles in these cases. Fortunately, we are getting over crisis thanks to people’s participation in energy conservation drive, demand control, and adjustment of preventive maintenance periods of power generation facilities.
In order to overcome such situation, electric power authorities and experts are discussing ways of minimizing abnormal symptoms in power industry, such as improvement of electric charge system, recovery of functions for removing social conflicts, reinforcement of procedures for collecting opinions, and improvement of power supply and demand system.
It is urgently needed to reach a social consensus to move toward a country that can achieve sustainable development by keeping win-win relationship between the government and individuals.
