Effects of COVID-19 on the electricity sectors of Ukraine and Hungary: challenges of energy demand and renewables integration

Energy assistance programs in Ibero-America and their adaptation to the COVID-19 pandemic

“…Due to the confinement measures, new behavior patterns considerably modified the electricity demand profiles, with demand reductions, displacement of consumption peak hours [ 26 , 27 ], and changes in the energy mix used to generate energy [ [28] , [29] , [30] , [31] ]. Academics and researchers quickly became interested in the operation of the electricity system under these new conditions, especially in the consequences of the electricity demand reduction [ [7] , [8] , [9] , [10] ], the impact on the development of renewable energy projects [ [36] , [37] , [38] , [39] , [40] ], and in the technical and economic challenges faced by the companies involved in electricity supply [ 29 , 41 , 42 ].…”

An impact study of COVID-19 on the electricity sector: A comprehensive literature review and Ibero-American survey

“…In Poland , the average daily electricity consumption in May 2020 decreased by 6.9%, and the peak was 6.4% smaller than in 2019 in the same period [ 25 ]. In Ukraine and Hungary , the decrease in electricity consumption in the first half of 2020 compared to the same period in 2019 was 4.9% and 3.6%, respectively [ 26 ]. In Portugal , electricity consumption was reduced by 12% and 13.2% in April and May compared to 2019, respectively, and overall, the electricity consumption in the first half of 2020 faced a 5.1% reduction, reaching the lowest level since 2004 [ 27 ].…”

“…In Italy , the share of energy supplied by renewable energy sources increased, reaching a daily renewable penetration higher than 40%, while the average seasonal value was about 23% [ 59 ]. In Ukraine in March 2020, compared to March 2019, generation at wind and solar power plants was doubled [ 26 ]. In Belgium , Italy , Germany , Hungary, and East U.S., renewable energy sources substantially increased in the electricity generation mix with an hourly record of renewable energy shares [ 62 ].…”

“…In Italy, the share of energy generated by renewable energy sources grew, which reached a daily renewable penetration of more than 40%, whereas the average seasonal value was recorded at about 23% ( Ghiani et al, 2020 ). In Ukraine, a comparison between March 2020 and March 2019 showed that energy production at the solar/wind power plants doubled ( Morva et al, 2020 ). In Belgium, Hungary, Germany, Italy, and East U.S., a considerable increase was observed in the renewable energy sources in the electricity production mixed with an hourly record of renewable energy shares ( Mofijur et al, 2021 ).…”
