Abstract

A system for scheduling the generation of energy in an energy distribution network having a plurality of customers and a plurality of energy sources, wherein the customer chooses an energy provider from which to receive its energy. The system comprises memory in communication with the input. The memory is configured to store a schedule for each customer, the schedule setting forth the predicted energy consumption for that customer over a predetermined period of time. A processor is in communication with the memory. The processor is configured to sum the schedules for each energy provider thereby creating a load schedule for each energy provider. An output interface is in communication with the processor. The output interface is configured to output each of the load schedules.
