Abstract:
1. A system for analysing energy usage on an energy supply network which includes a number of energy sources supplying energy to the network, and a number of energy consumers connected to the network, the system including a plurality of meters on the network which monitor energy usage on the network, the meters supplying data to data processing apparatus which aggregates the data so as to provide an indication of current total energy usage, and which stores data so as to permit the retrieval of historical energy usage for a time in a year, wherein the data processing apparatus further compares current total energy usage for a particular time in a year with a standard total energy usage for that time in a year, based on historical energy usage, and generates an index which indicates the difference between the current total energy usage for that time in a year and the standard energy usage for that time in a year.
