The analysis results of current and voltage harmonic composition in the AIC enterprise networks in the Krasnoyarsk region central parts are given in the article. The changes show that electric power quality indicators of the researched power users mostly meet the ГОСТ 13109-97 standards. It is determined that nonlinear load share increase which is caused by energy-saving technology use will cause the higher harmonic level increase in the spectrum of current and voltage.
