Calculate capacitor size

An electrical supply company charges its consumers a penalty if their reactive energy consumption (Kvar-hour)exceeds half their true energy consumption (Kilowatt-hour). Calculate the value of the parallel capacitor required to be installed at the factory to avoid the penalty. The supply is 240 Volts ac @ 50Hz the total load impedance is Zt = 3.04 at 35.5 degrees The power factor is 0.81 Now I know that: apparent power S = 32594.05 Active power P = 26535.32 Reactive power Q = 18927.46 Using the formula: C = 1/w [1/Zt * Sin Q - 1/Zt * Cos Q * Tan Q] I get C = 0.000181 which I know is the correct answer. What I need help with is how do I get P or S from the det... click for more
