Electric Curve of Large Industrial Power as Diffusion Index


  1. The electric curve of large industrial power is an indicator for assessing the current state of the economy from the power demand side.
    It shows the year-to-year growth of the volume of large industrial power (including independent power generation) and large-scale contracted power.
    However, movement of the electric curve of large industrial power does not accord with the economic performance after the Great East Japan Earthquake (March 2011), due to the effect of earthquake disaster and electricity saving.
