“…Many examples for both of these approaches can be found in the recent literature. The bottom-up research approach has been implemented by studying the effects of the pandemic on power systems in several countries, such as the United States [4], China [5], Italy [6], Spain [7], Brazil [8], Canada [9], India [10], Sweden [11], Israel, Estonia, and Finland [12]. One clear trend emerging from these works is the effects of the pandemic on energy consumption patterns and peak demand, mostly due to the preventative measures taken by governments [13].…”

Effects of the COVID-19 Pandemic on Energy Systems and Electric Power Grids—A Review of the Challenges Ahead

et al. 2021

The COVID-19 pandemic represents not just a global health crisis, but may signal the beginning of a new era of economic activity, the potential consequences of which we currently do not fully understand. In this context, the mid-to-long-range impacts of the pandemic on the energy sector have been studied extensively in the last few months. Despite these efforts, the pandemic still raises many open questions concerning the long-term operation and planning of power systems. For instance, how will the pandemic affect the integration of renewable energy sources? Should current power system expansion plans change in light of the COVID-19 pandemic? What new tools should be provided to support system operators during global health crises? It is the purpose of this paper to better understand the many aspects of these open questions by reviewing the relevant recent literature and by analyzing measured data. We point out the main challenges that the pandemic introduced by presenting patterns of electricity generation and demand, frequency deviations, and load forecasting. Moreover, we suggest directions for future research that may assist in coping with the mentioned challenges. We hope that this paper will trigger fruitful discussions and encourage further research on these important emerging topics.

“…In the U.S. , overall electricity demand declined by less than 10% from late March to June 2020, compared to energy consumption before the shutdowns [ 32 ]. In Brazil , the decrease in electricity loads was 15% compared with data before the beginning of the isolation decrees [ 18 ]. In Colombia , April and May 2020 were the months with the highest reduction in electricity consumption, accounting for a decrease of 12% and 8%, respectively, compared to 2019 [ 27 ].…”

“…Even though the pandemic is still not under control in several parts of the world, its varied impacts on the global economy are already evident. In the electricity sector , the confinement measures have caused unseen impacts in history, mainly due to the pronounced and prolonged reduction in electricity demand caused by the paralysis of commerce and industry, large energy consumers [ 18 ]. The resilience that power systems had developed throughout history was aimed at preventing supply outages in the event of natural disasters; therefore, the demand reduction, changes in consumption patterns, and high debt levels that will accompany the sector over the coming decades are challenges for which not all the world's electricity systems are equally prepared.…”

To stop the spread of COVID-19, governments have implemented confinement measures unprecedented in modern society. One of the main consequences has been the paralysis of commercial and industrial sectors worldwide, primary electricity consumers. This paper examines the impact of these measures on the electricity sector through a literature review accompanied by fieldwork on the impact of COVID-19 in Ibero-America and its energy regulatory response. First, we will review the causes of the reduction in electricity demand due to the confinement measures and their technical and financial consequences in the electricity sector. Second, we will examine the impact of COVID-19 on the wind and solar PV energy sectors, mainly affected by the paralysis of production and export of materials and components. Third, we will revise the regulatory measures implemented by the countries to avoid the interruption of electricity supply to households. This paper will end by reviewing economic recovery plans and their relationship to the energy transition. Although there are no fundamental differences between developed and developing countries in their regulatory reaction to this crisis in the energy sector, there are significant differences in economic recovery planning. While developed countries aim for a green economic recovery and the creation of green jobs, developing countries are allocating least resources to social protection and general economic stimulus programs, postponing climate objectives. In Latin America, this adds to the high levels of debt faced by utilities and the possible resurgence of social crises that were stopped by the COVID-19 outbreak, making a green recovery even more difficult.

“…By contrast, with no lockdown during the pandemic period, Sweden illustrated an increase in electricity consumption compared to the pre-pandemic days ( Bahmanyar et al, 2020 ). After the enactment of social distancing in Brazil, the overall electricity loads fell, and the highest reduction was observed in the South subsystem ( de Delgado et al, 2021 ). Despite the pandemic-induced drop in total electricity consumption, the lockdown substantially exacerbated the prevailing energy poverty worldwide by increasing domestic energy demand amidst the financial crisis ( Mastropietro et al, 2020 ).…”

Behavioural changes in air-conditioner use owing to the COVID-19 movement control order in Malaysia

Remote work (working from home) became a norm rather than an exception for the global workforce during the COVID-19 pandemic, influencing every facet of life in both positive and negative ways. The stringent action of the Malaysian government in enacting the Movement Control Order (MCO) motivated the investigation of its impact on the energy consumption behaviour of working people regarding air-conditioner (AC) use. To this end, this study conducted a cross-sectional survey through an online platform. An ordinal logistic regression model (ORL) was used to analyse the collected data of 1873 respondents to determine the factors influencing the ordinal variable of interest, AC-usage behaviour during remote work. Next, the variable with unordered categories, the MCO-induced change in AC-usage behaviour, was analysed using a multinomial regression model (MLT) to identify the potential determinants. Finally, a reason analysis unveiled aspects behind the transition in AC use during remote work. This study identified stopping AC use during remote work despite using it at the office before the MCO period as the most significant change in AC-usage behaviour due to MCO. This change was frequently adopted by people with medium-level incomes and high electricity bills. By contrast, participants unfamiliar with their electricity bill were most likely to start AC use during remote work, although they did not use it before the MCO. Participants working remotely in the communal spaces of their houses preferred to stop using ACs during MCO compared to private room users. Furthermore, age group and ethnicity significantly influenced AC-usage behaviour in remote work and changes in such demeanours. These findings recommend policy interventions to expedite limited AC use for a sustainable energy sector, even during future climatic emergencies.
