The technology of digital twins is a basic one in the process of energy "digitalization." An essential component of the digital twin development is data collection from a physical facility to monitor and control this facility. Advanced information support systems designed to control the UES of Russia (SCADA and WAMS) provide control centers with considerable amounts of information, which can be used to create a digital twin of an individual energy facility or entire power system. This paper proposes the use of edge analytics technology that enables the collection, processing, and analysis of data on network peripheral units near the information source, to reduce the amount and cost of transmission and storage of a whole host of data when creating digital twins of energy facilities. A modern digital substation is considered as a facility to be digitally twinned.
