The automated system for monitoring, control and management of energy consumption serves to collect arrays of information on energy consumption of large industrial sites in order to optimize energy costs through continuous ongoing control and control of costs in previous periods through an archive in databases. Instant views of the momentary status of the system are available through common Internet browsers for all remote users.
