An alternator is supplying load of 300 kW at a power factor of 0.5 lagging. If the power factor is raised to unity, how many more kilowatts can alternator supply for the same kVA loading?

600 kW
150 kW
450 kW
300 kW

P = S*cosφ
S = P/cosφ
S = 300/0.5
S = 600 kVA
For same kVA rating and unity power factor,
P = 600*1
P = 600 kW
Pextra = 600 - 300
Pextra = 300 kW
