What Is Power Supply Capacity in Above Time Slot

This is the maximum amount of power that can be generated in each time slot. Please note that this is not identical to the total capacity of the power-generating facility.

Power supply capacity in above time slot

This is the maximum amount of power that can be generated in each time slot. It is calculated by taking the total capacity of the power-generating facilities and subtracting factors such as the stoppage of generators due to maintenance and the decrease in output due to a decrease in river water volume.
Since the operation conditions of power-generating facilities and river flow rates fluctuate daily, the supply capacity also fluctuates daily in conjunction with these factors.

  • 1 Supply capacity at peak demand time

    Maximum power output at time slot when highest demand for the day is expected

  • 2 Supply capacity at peak usage ratio time

    Maximum power output at time slot when highest usage ratio (percentage of power usage against power supply) for the day is expected
