A medium-rise building with inductive loads has an average consumption of 40 kW and 26 KVAR. At the area where the building is located, the electric utility imposes a surcharge (or additional payment, in %) based on the power factor of the load. The utility uses the table below to determine the surcharge. Power factor Surcharge 90 to 100% None 88 to <90% 2% 85 to <88% 4% 80 to <85% 9% 75 to < 80% 16% 70 to < 75% 24% 65 to < 70% 34% 60 to < 65% 44% 55 to <60% 57% 50 to <55% 72% Less than 50% 80% The building occupants are planning to avoid the additional cost by installing a capacitor (to be connected in parallel with the building) for localized reactive power production. The target is to reduce the surcharge to 0%. a. What is the minimum KVAR the capacitor should produce to meet the target?
