Power factor correction: PE Power Circuit Analysis practice question

The 480 V main bus of a packaging plant carries a load of 750 kW at 0.78 power factor lagging. The utility tariff adds a charge whenever the monthly power factor falls below 0.95, so the plant will install a fixed capacitor bank at the bus to raise the power factor to exactly 0.95 lagging. The real power drawn does not change.

The capacitor bank rating required is most nearly:
