Demand Control Overview
The Art of Intelligent Peak Load Control
Demand Charges can account for up to 35% of your utility bill. The electric demand for a facility usually varies hourly, daily, and seasonally. The supplier must have generating capacity, transformers, and distribution equipment installed to provide the peak demand at any time even if it only occurs one hour a month. The supplying utility recovers the cost of providing the equipment required for this maximum demand in commercial and industrial rates by a separate charge called the demand charge.
Demand Control is the art of Intelligent Peak Load Control to avoid demand peaks and their associated expense in a facility without jeopardizing operations and achieving significant cost avoidance.
How does Intelligent Peak Load Control work?
The electrical power used is transmitted synchronously to a utility measurement device. The transmitted actual power is monitored by a microprocessor, controlled, and continuously compared with target values. Trending is performed to evaluate power ratios in order to curtail loads / load groups connected to the Emacx Load Controller.
The microprocessor calculates all necessary curtailment operations and prevents loads / load groups from being reduced unnecessarily. It then enables optimal utilization of the target nominal power consumption. Each month of the year has an assigned maximum demand threshold that the system will maintain. The connected equipment is controlled as a function of assigned priority levels and duty cycle parameters. When called for curtailment, designated equipment is reduced for a short duration until the demand reduction objective is achieved.
