For the configuration of regional network, TEPCO's service covers compiling of Regional Power System Planning Manual and producing of Regional Power System Master Plan, both of which will best fit the design needs of your regional network to achieve a certain required level of system reliability. We already have the long experience of power system planning by which we have coped with the expansion of the Japanese economy.

For assessing the effect and seriousness of a possible contingency in the regional network, TEPCO can make them clear and provide the most appropriate solution by using our own software, "Expected Outage Simulating System (EOSS)". This software enable users to identify which part of the network is more vulnerable than the other by simulating line or equipment failures, indicating heavily-loaded areas so as for them to help establish reconfiguring plans for power network improvement.
