Effects of COVID-19 on Electrical Energy Demand based on Spatial Analysis – A Case Study of Phetchaburi, Thailand

The outbreak of COVID-19 has resulted in a shift in economic and social conditions. Most of the electrical energy use is in buildings or dwellings near utility facilities. Therefore, this paper presents a case study of electrical energy use in Mueang Phetchaburi district, Phetchaburi province, Thailand, to study the behavior of electrical energy consumption changes during the COVID-19 pandemic. COVID-19 affects everyday life, such as rapidly decreased and increased electrical energy consumption in some areas. In this paper, the application of geographic information system (GIS) and python programming has been proposed and applied in spatial energy analysis. The results show that the total electrical energy consumption is decreased by approximately 24.48%, and the electrical energy consumption is significantly decreased in the medium business sectors. Whereas, the electrical energy consumption is slightly increased in the residential and commercial sectors. Moreover, the changes in patterns and behaviors of electrical energy uses and how the electrical energy flow affects urban areas can be understood easily.
