The heat input per day to the power station if it works for 20 hours at full load and remaining period at no load.

Question

The input-output curve of a 60 MW power station is given by I = 5 x 10⁶ [8+8L+0.4L²] kJ/hr.

Where, I  = Input in kJ/hr

  L = Load in MW

Determine :

1. The heat input per day to the power station if it works for 20 hours at full load and remaining period at no load.
2. Saving per kWh of energy produced if the plant works at full load for all 24 hours generating the same amount of energy.
