The ongoing COVID-19 related shutdowns has had a profound impact on the electric demand profiles worldwide, as governments put strict mitigation and/or suppression measures in place. The global electrical demand has plummeted around the planet in the last few weeks, with countries such as Spain and Italy experiencing more than 20% decrease in their usual electric consumption. In view of such massive electric demand changes, electricity network operators are facing unprecedented challenges in scheduling energy resources, as short-term energy forecasting systems struggle to provide an accurate demand prediction.
