In 2020, electricity consumption (284 TWh) recorded a decrease of -6% (-1% in 2019), mainly due to the extraordinary pandemic situation that occurred during the year. The downturn affected all consumer sectors, in particular the tertiary and industrial sectors, with the exception of the domestic one where there was an increase in consumption of + 2%. This is what emerges from the Arera Annual Report, the Regulatory Authority for energy and the environment, on the state of services and on the activities carried out in 2020. National demand was satisfied for 90.2% (the 88% in 2019) from national production, while for the remainder from the foreign balance, for a level never so low in the last twenty years. Imported energy decreased by 9.5%, while that exported, however of a limited amount, also increased in 2020 (+ 30%). In 2020, Arera notes, the gross national production of electricity in Italy was 281.5 TWh (-4.2%), compared to 293.9 TWh in 2019. The extraordinary pandemic event recorded a decrease compared to the previous year, when there was a recovery in production (+ 1.4%), compared to the decrease of about 2% in 2018. The thermoelectric plant went from 176.17 to 163.54 TWh (-7.2 %), while renewable sources showed a slight increase overall, despite a 7.4% contraction in production from wind power and 0.8% in geothermal. The production of solar energy, in particular, recorded an increase of 5.3% compared to 2019 when the production from this type of source was 4.6%. 41.2% of the energy demand on the grid was met by production from renewable energy sources (renewable hydroelectric, wind, photovoltaic, geothermal and biomass), recording a value of 116.05 TWh (+ 1.3% compared to ‘last year).
