First you will never have pf 1 in industrial condition
without capacitor bank approx 0.98 max with capacitors

Specify reactive power or power factor and voltage level to
calculate capacitor requirement,

Answer / wareagle

The need for capacitors is determined by load power factor
and utility billing rates. If you load has a PF of 1.0,
then no capacitors are needed. If the utility does not bill
for low PF, then you may not need capacitors.
