Air temperature rise due to global warming can increase the demand for electricity, because of the more frequent and intensive use of air conditioners and fans. Based on this phenomenon, it is necessary to study the correlation between air temperatures and peak electric demands. This study aims to obtain a correlation between maximum air temperatures and peak demand and then estimate the peak demand of Padang city for the year 2030. The correlation between air temperatures to peak demand is identified by Pearson coefficient. The demand forecasts are calculated using a multivariable linear regression method. Correlation test results show a low correlation between maximum air temperature and peak demand but a strong correlation between population and peak demand. The results of the forecast for 2030 are 422 MW for case 0, where the independent variables are the population and daily maximum air temperature. The peak demand is 421.59 MW for case 1, where the independent variable is only the population. For case 2, where the independent variables are population and daily maximum air temperature according to Paris Agreement, the peak demand is 421.03 MW. The forecast result that excluded the air temperature resulted in 410 KW lower peak demand than the forecast that includes air temperature. The higher air temperatures result in higher peak demand.
