The estimation of geomagnetically induced currents that can affect the power grid system was conducted based on measurements from mid-latitude geomagnetic observatories in this study. To accomplish this, the grid line in the territory of Amaty oblast, Kazakhstan, was selected, and the geophysical conditions in the region were investigated. It was determined that due to geomagnetically active periods, Kazakhstan's energy systems affect by geomagnetically induced currents for a significant duration that depends on the geomagnetic storm value and time of its lasting, with the rate of geomagnetic field changes exceeding 17 nT/min. And the value of the geomagnetically induced currents can vary from fractions of mA to tens of mA.
