Abstract
The Covid-19 pandemic had wide-ranging effects on how people lived, worked and learned. Consequently, electricity use was altered from pre-pandemic patterns. The deviation from expected electricity usage patterns in commercial properties due to the Covid-19 pandemic was analyzed in a medium-sized American city. The focus on a single community (1) allows usage to be linked specifically to the timing of public health and executive orders; and (2) provides a fine-grained, detailed understanding of usage in different property classifications (e.g. restaurants, hotels, schools, outpatient medical facilities, offices, and religious organizations). Electricity consumption data from 2019, adjusted for average daily temperature, were used to calculate expected use in 2020. Electricity usage was found to be lower than expected for most commercial property classes, but the timing and magnitude of these effects varied. For example, within the hospitality industry, hotels evidenced a larger and more sustained decrease in usage (–17%) as compared with restaurants (–11%). In addition, usage patterns for outpatient medical facilities can be linked to specific executive orders. Together, a heterogenous rate of electricity use is found to vary according to specific types of commercial properties.
Practice relevance
In much of the research regarding electricity usage, utility customers are placed into the broad categories of residential, commercial and industrial. These groups are viewed as homogeneous. This study examined different property classes within the commercial group during the Covid-19 pandemic. Although electricity usage was lower than expected for most commercial property classes, the timing and magnitude of these effects varied. For example, within the hospitality industry, hotels evidenced a larger and more sustained decrease in usage than did restaurants. In addition, usage patterns for outpatient medical facilities were linked to specific executive orders. Together, these data sources allowed for a detailed examination of Covid-19’s effect on electricity use for specific types of commercial properties and it revealed that their response to the pandemic varied widely. Thus, it is an oversimplification to view commercial properties as a single, homogeneous group.
