For a Sustainably Prosperous Future
Energy exists all around us, though not always at the right time.
PowerX’s battery systems turn that potential into dependable power for all.
Achieving Japan’s Energy Independence
Japan’s energy self-sufficiency is only 15.3%—among the lowest in the OECD—reflecting reliance on imported oil, gas, and coal. The government’s latest energy plan calls for a shift to sustainable power not only to protect the environment, but also strengthen energy independence. PowerX will lead this transition with reliable battery power plants essential to achieving this goal.
