Toshiba
contributes to stable advanced transmission and distribution of electricity towards
the realization of a super smart energy society
The power
industry is required to flexibly respond to the environment surrounding the
power transmission and distribution, including distributed energy systems,
energy liberalization, and large-scale natural disaster preparedness. In
order to realize a more comfortable and environment-friendly smart energy
society, we are taking actions towards solving social issues through our
transmission & distribution business.
