Electric generators are machines that provide electricity specially during power interruptions or when electric power is not yet available in the area. Although it is always claimed by manufacturing companies of electric generators that the system produces a stable electric outputs, fluctuations of electricity arise due to variation on the load the generator carries that causes the damage to appliances or facilities. This study focused on solving this problem by designing and fabricating an automatic electric load controller (AELC) that can help in producing a stable voltage and frequency generated that can be used not only in farms but also at home and other establishments without damaging the facilities loaded. Proportional integral derivative (PID) was also included in the program. This study also simulated the use of the AELC for a microhydro electric generators by using an assembled 3KVA electric generator without mechanical governor. The developed AELC was tested using a fabricated electric generator and was found to be efficient in terms of the maintained RPM of 1800/60 Hz and voltage of 220 volts.
