One of the most important factors in energy consumption is environmental conditions. This study aims to examine the relationship between temperature and electricity consumption in Babolsar city in Mazandaran province. The main issue in this study is to find different patterns of relationship between temperature and electricity consumption in this city. Daily electricity consumption and daily temperature, were collected from 1 Jan 2010 to 31 Dec 2019, from the Electricity Department and the Babolsar Synoptic Station. Threshold regression method was used to find the breakpoints of the regression line between temperature and power consumption. Findings revealed there were 3 distinct thresholds in the relationship between consumption and temperature. The first threshold was about <20 ±3 ° C. The last threshold was 26 ±1≥ and the middle threshold was between these thresholds. The sensitivity of electricity consumption of the third threshold temperature is the most. Examination of the trends of the thresholds showed that the first and second threshold temperatures had a decreasing trend and the third threshold trend was increasing. Due to the increase in the number of temperatures of the third threshold, which electricity consumption is most sensitive to these temperatures, this case should be considered by managers in electricity management.
