A station of 500 MW capacity generating 2628 GWh in a year has a plant load factor of about

  • A.60 per cent
  • B.50 per cent
  • C.72 per cent
  • D.80 per cent

Answer: A

Correct answer: 60 per cent

The maximum possible generation is the capacity running continuously: \[ 500\ \mathrm{MW} \times 8760\ \mathrm{h} = 4{,}380{,}000\ \mathrm{MWh} = 4380\ \mathrm{GWh}, \qquad \frac{2628}{4380} = 0.60. \] The 8760 hours in a year is the constant to have ready; every plant load factor and capacity utilisation calculation runs through it.
