Abstract

Methods and arrangements for calculating a power budget. Data are received, the data including data relating to a current state of an electrical grid at a power-drawing location which draws at least one variable electrical load, the at least one variable electrical load being subject to variable pricing. At least one prediction is determined, the at least one prediction pertaining to a future state of the electrical grid and a future electrical load to be drawn at the power-drawing location. A power budget is thereupon calculated, with respect to the power-drawing location, based on the data and the at least one prediction. Other variants and embodiments are broadly contemplated herein.

Claims
