Recently in conducting our corporate energy assessments, we’ve come across more frequent situations where our customers are incurring high demand charges from their utilities.  In most cases they haven’t known the relative size of these charges, nor that they can often be reduced or even avoided.

As we dig in, studying interval data from their utility bills and correlating usage with their operations, we typically discover that large loads (ventilation, chillers, machinery) can be time shifted an hour or two with limited impact to the overall business.  Depending on the size of the load, time of day and the utility’s demand charge rate, this can have huge dollar savings impact.
