Transmission and Distribution

With accumulated technologies and experiences in Japan as well as overseas, TEPSCO can provide not only services related to overhead and underground transmission lines, substations and distribution equipment, but also soft side services including system analysis for optimum power flow, planning for load dispatch/control to minimize the outage time for the power supply, and reduction of transmission losses. Based on the latest technology, TEPSCO can propose a total energy solution for energy conservation, energy savings and harmonization of the surrounding area. In recent years TEPSCO has been very highly evaluated by foreign power utilities for our services in many countries such as Egypt, Iraq, Laos, Sri Lanka, Bangladesh, Thailand, and Taiwan.
