As commercial fleets adopt more electrically-powered hardware, including vehicles and transportation equipment, new demands are being placed on the existing electrical infrastructure. Demand management is critical as facilities reach their electrical capacity through growing electric energy demands or come under electricity use restrictions through banding and time-of-day use agreements (which incentivize reduced demand on electrical resources). Most current demand management systems focus on reactive actions such as denying availability (e.g. rolling brown out) during peaking events. In many situations, this denial of service may be highly undesirable, as is the case with electric-powered transport refrigeration units (eTRUs), which must maintain a narrow temperature band to protect perishable products.
