Household electricity demand forecast and energy savings potential for Vientiane, Lao PDR

摘要

This paper uses the survey data on household electricity demand from five districts of Vientiane, Lao PDR, for the demand projection up to 2030 using the end-use model. The scenario analysis is used to verify the potential of an energy-saving program by alternating selected appliances with more energy-efficient ones following the labelling standard of Thailand. The demographic structure of electrified households and the energy efficiency of electric appliances are considered as the dominant factors affecting electricity demand. Under the base-case scenario, the total electricity demand of Vientiane increased from 593 GWh in 2013 to 965 GWh in 2030. In the energy efficiency scenario, it is revealed that the appliance standard enhancement program can save total electricity demand in 2030 by 147 GWh (?15.2%), where 117 GWh (?12.1%) of which is contributed by the air conditioner and 30 GWh (?3.1%) by the lighting equipment.
