Construction, operations and maintenance support

Since infrastructure is shared over long periods of time it is important to build facilities from the standpoint of how much maintenance costs can be reduced and to what degree the equipment can be made efficient. In addition, it is often the case that work is suspended for inspections and maintenance, the plants are shut down due to an increase in water caused by typhoons and others, and power cannot be generated due to unforeseen troubles, such as part malfunctions. By leveraging the technical skill and knowledge that we have cultivated over many years through our hydroelectric power business, TEPCO will provide support for everything from the construction to the operation and maintenance of power stations, and also aid with optimizing equipment and making power generation management more efficient, which are often problem areas.

Gate aseismic performance investigation

Gate aseismic performance investigation

Are you replacing equipment that is still usable?

Repair costs can be reduced by equipment diagnosis technology

Generally, generator replacement timing is uniform (CRIEPI finding)

Replacement period can be extended by conducting lightning surge analysis of individual plants (setting of individual replacement standards)
