The continuously increasing temperatures worldwide indicate that the frequently extreme heat in summer will become a new normal. The extreme high temperature (EHT) could be dangerous to human health, especially for outdoor workers or commuters, and could increase the risk of grid collapse. Thus, the possibility of a day off due to EHT has started to be discussed in Taiwan, based on the experience of typhoon day off, but discussions have not yet concluded. In this study, the effects of the EHT day off on electricity consumption in the industrial, service, and residential sectors were investigated through two determinants: First, high temperature would increase the electricity consumption in space cooling. Second, a day off would change people’s behavior of electricity consumption from workday to nonworkday modes. Combining the effects of cooling hours and nonworkdays, the net influence of the EHT day off on electricity consumption can be evaluated. Estimated results indicated that an EHT day off can reduce aggregate electricity consumption by between 0.41% and 1.08%. The reduction of electricity consumption due to the off day offsets the increase driven by high temperatures. Thus, an EHT day off will mitigate the pressure on the power grid and benefit electricity conservation.
