A load calculation control method and apparatus for load characteristic tests of electric generator and the like is provided, which enables continuous and precise following of a load control value and maintaining the value without using industrial water. In this apparatus, a resistor bank .alpha., which is to be connected to a load apparatus provided with a power supply apparatus (G), a ground relay (GR), a voltmeter (V), an electric power meter (P), an ampere meter (A), and main circuit breakers (CB, CBH), is divided into two or more (2-N). A switch (CL/CH) and a controller (CV) are connected to each resistor bank (.alpha.1-.alpha.N). each of which is assigned and maintained at a power capacity obtained by dividing, based on binary number, the maximum power capacity of resistor bank groups (.alpha.L, .alpha.H) by two through (2n-1). The controller (CV) includes a control value storing circuit (MC) that holds a load control value and a comparing/transmitting circuit (OC) that compares the power capacity value of the resistor banks (.alpha.1-.alpha.N) with the load control value and that transmits ON/OFF signals to the switches (CL,CH) connected to the resistor banks (.alpha.1-.alpha.N) .
