PLF and CUF of Windfarms in India

Different benchmarks have been fixed for CUF ( Capacity Utilisation Factor) in different states. This is important as deviation will decide the tariffs.
CUF varies from minimum 19 ( Odisha) to maximum 30 ( Maharashtra and Uttarakhand).
State with high CUF may contribute less to generation because:

  • both low rating and high rating turbines are installed in some states.
  • wake losses increase as number of turbines increase.
  • wind pattern changes in due course of time.
