Fixed system energy consumption in multi-user energy consumption reporting
Disclosed herein are methods and apparatus of reporting the energy consumption of individual customers of a multi-user installation, including determining the fixed system energy consumption of the installation attributable to the individual customers. In an example, a device determines a base load energy of a data transmission system over a time interval. Further, the device generates a report of energy consumption attributed to a customer of the data transmission system based on the base load energy of the data transmission system over the time interval weighted by a fraction of a capacity hired by the customer, and the energy attributable to data of the customer transmitted at a determined data rate over the time interval. In a further example, the report of energy consumption attributed to the customer is generated further based on an actual data rate of the data of the customer.

transmitting data of a customer (n i ) at a determined actual data rate over a time interval (p base (t 2 −t 1 ), wherein p base is based on a base load energy of a data transmission system and t 2 −t 1 is the time interval between first time and second time;
receiving and determining energy attributable to the data of the customer (n i ) transmitted at the determined actual data rate over the time interval;
determining the base load energy of the data transmission system over the time interval (p base (t 2 −t 1 )); and
generating a report of energy consumption (E n i (t 1 , t 2 )) attributed to the customer (n i ) of the data transmission system based on the base load energy of the data transmission system over the time interval weighted by a fraction of a capacity hired by the customer (n i ), and the energy attributable to the data of the customer (n i ) transmitted at the determined actual data rate of the data of the customer (n i ) over the time interval, wherein:
