Load dispatching operations responsible for delivering high-quality electricity to the customer on a stable basis control electric power 24 hours a day, 365 days a year driven by two wheels; (1) Central Load Dispatching Center responsible for keeping good balance between electricity generation and consumption (supply and demand operations)and (2) Primary Dispatching Center responsible for keeping the path of electricity flow (power system operations).

At the divisions responsible for stable power supply led by Central Load Dispatching Center and Primary Dispatching Center, various training programs are performed on a regular basis so that employees are able to take accurate and prompt actions in case of an emergency.

Accident restoration training using simulators is conducted to keep and enhance technical capabilities of our employees so that they can take prompt and accurate actions in the event that an accident due to natural disasters occurs.

At the end of October, total 3 rounds of large scale accident restoration training sessions were conducted with a large number of participants from nuclear power plants and thermal power plants as well as branch dispatching control offices that keep the path of electricity flow along with the Primary Dispatching Center.

The training drill assumed that a lightning strike caused major power supply shutdown and outages in a wide area.

All the participants tackled the drill as a single team with a strong will in mind that "we should resume power supply as quickly as possible" under pressure to grasp the whole status of the accident, figure out the solutions considering the status, and to give accurate instructions quickly.

Lightning strikes account for about 80% of all causes of power system accident (as shown in Fiscal 2012 records). Taking into account this fact, we are making every effort to mitigate the impact resulting from lightning as well as to tackle the training assuming an accident.

Central Load Dispatching Center (Osaka prefecture) and Primary Dispatching Center (Kyoto prefecture) are closely working by merging and linking mutual power systems to locate load dispatching centers in a distributed way.

Building a mutual backup system that enables seamless operations without necessity of exchanging employees; in the event that one system goes down or a disaster hits a center, functions are shifted to the other so that operations can continue unimpeded.

Employees of both centers participate in the training on a regular basis so that they are able to play an alternate role in the other office to maintain stable power supply in case of an emergency.

Central Load Dispatching Center and Primary Dispatching Center conducted total 5 rounds of mutual backup training in October.

In the course of the recent drill, employees of Central Load Dispatching Center were engaged in power system operations while Primary Dispatching Center employees were engaged in supply and demand operations by switching the systems with each other assuming a disaster due to an earthquake or fire and system failure.

Around noon when the amount of power usages largely fluctuates in a day, all the employees were under immense pressureand voices sending instructions to the power plants were sounded like "Frequency increasing! Parallel off the generator!" "Generator paralleling-off, OK" with ringing sounds of setting the equipment to adjust the output of power plants.

Employees are making a continuous effort through training to learn system operations and maintain and enhance expertise and skills necessary for backup tasks.

Central Load Dispatching Center and Primary Dispatching Center, both of which are the essential electricity control centers, devote themselves to keeping stable power supply. They perform accident restoration training and mutual backup training in case that the system goes down or a natural disaster occurs with a feeling of tense and calmness while keeping in mind that "perform training as in a practical job, and engage in practical operations as did in training".
