Abstract: Disclosed are a power management system and associated method that not only initiate a “greenout” to avoid the negative impact of high loads (i.e., to avoid high power cost, negative environmental impact, brownouts, and ultimately blackouts), but can also predict the initiation of such a “greenout”. Predicting the initiation of a “greenout” and communicating the prediction to one or more of the various electronic devices connected to the power grid allows the electronic device(s) to take preparatory action to avoid and/or limit any negative impact that may be caused by the “greenout”.
