COVID-19 pandemic, lockdown, and consequences for a fossil fuel-dominated electricity system

In South Asian countries, the spread of COVID-19 was not treated seriously until mid-March 2020. Measures similar to those considered in Europe and other developed countries, such as maintaining social distance and lockdowns, were imposed. Lockdowns imposed a significant impact on the power sector, and this has been well explored in the literature for developed countries. A country-specific assessment of the impact of COVID-19 on the energy sector is crucial for future crisis management and underpinning sustainable power sector development plans. The impact of COVID-19 on Bangladesh's fossil-fuel dominated electricity sector is explored in this study. The analyses were conducted for 2019 and for the pandemic lockdown period in 2020. Daily hourly demand variations for different electricity generation zones in the country were investigated. The impact of these demand variations on greenhouse gas (GHG) emissions was assessed through time-varying carbon intensity analysis. Nationwide, the analysis revealed that the maximum hourly demand reduced by about 14% between 5 and 6 pm whereas the minimum demand reduction (3%-4%) occurred between 7:30 and 8 pm. Peak time demand reduction was found to be minimal during lockdowns. The national absolute GHG emission reduced by about 1075 kt CO(2)e, an similar to 16% reduction compared with that in 2019. Time-varying carbon intensity patterns varied significantly between zones.

Automated summary

In South Asian countries, measures similar to those in Europe and other developed countries, such as maintaining social distance and lockdowns, were imposed to control the spread of COVID-19. This study explores the impact of the pandemic on Bangladesh's fossil-fuel dominated electricity sector, finding that the demand variations during the lockdown period affected greenhouse gas emissions.
