Abstract: Electrical power load data is obtained for a power consumption facility for a period of time of at least one year. A load duration curve is created for the power consumption facility for the period of time based on the electrical power load data. Anticipated electrical power production data is obtained for an inverter-based power generator for the period of time. A power generation curve is created for the inverter-based power generator for the period of time. The power generation curve is evaluated against the load duration curve to determine a required electrical power supply capacity and duration for an electrical storage system to cover peak power demand of the power consumption facility. An energy storage technology and configuration of the electrical storage system is determined for satisfying required electrical power supply capacity and duration for the electrical storage system to cover peak power demand of the power consumption facility.
