Abstract: Electrification is important for carbon reduction in urban residential buildings. It requires clean regional grids to achieve positive emissions efficiency. In countries where the condition of regional grid decarbonization varies, such as China, an aggressive electrification strategy may increase carbon emissions. However, existing research lacks attention to coordinating building electrification with regional grid decarbonization. This study projects the regional timetable when replacing fuel appliances with electric appliances can reduce carbon emissions from 2022 to 2050. Four strategies with different schedules are designed, of which the carbon emissions are compared under three grid decarbonization scenarios. Results find the following: First, in most regions, replacing gas appliances with high-efficiency electric ones can already reduce carbon emissions, while the transition to direct electric-to-heat appliances takes a long time. Secondly, the current national simultaneous strategy will increase carbon emissions by at least 52MtCO2 when using direct electric-to-heat appliances. The increments come from the Northeast, North, and East. Thirdly, high-efficiency electric appliances can reduce the sensitivity of the emission reduction potential of electrification strategies to the onset time. The study contributes to decision-making processes related to electrification strategies for urban residential buildings, providing a reference for assessing their potential to reduce emissions.
