Abstract: A method comprising requesting power measurement data from a power meter during a predetermined time period, receiving the power measurement data, associating a negative coefficient with the power measurement data if the power measurement is less than zero, associating a positive coefficient with the power measurement data if the power measurement is equal to or greater than zero, and calculating a power measurement for the power generation site based, in part, on the associated coefficients. The power meter can be configured to measure power usage from the EG site including power provided by an electrical utility grid and an EG system at the EG site. The power measurement data may include a first power measurement corresponding to a first phase of power and a second power measurement corresponding to a second phase of power.

Abstract: Techniques for controlling an energy storage device to reduce peak power demand at a site are provided. In one embodiment, instantaneous power usage at the site can be monitored, where the instantaneous power usage corresponds to power that is instantaneously imported or exported at a point of common coupling (PCC) between the site and a utility-managed energy grid. A historical power usage value for the site can then be calculated based on the monitored instantaneous power usage, and the historical power usage value can be compared with a target peak value plus a buffer value. If the historical power usage value exceeds the target peak value plus the buffer value, the target peak value can be set to the historical power usage value.
