PROBLEM TO BE SOLVED: To provide an apparatus for measuring power quantity and load quantity for use in a power generation system, capable of measuring the power quantity and load quantity in the power generation system correctly. SOLUTION: The power quantity and load quantity measuring apparatus in the power generation system, includes a watt-hour meter which converts DC power generated in a generator to AC power by a power converter, transmits it to a load, and measures a power consumption in the load. The apparatus includes a first current measurement unit which measures the current quantity in a first power line connected between the power converter and the load, a second current measurement unit which measures the current quantity in a second power line connected between the load and the watt-hour meter, a power quantity calculation unit which calculates the power quantity in the power generation system by using the current quantity measured in the first current measurement unit, a load quantity calculation unit which calculates the load quantity by power consumption in the load by using the current quantity measured in the second current measurement unit, and a display unit which displays the calculated power quantity and load quantity, respectively.
