Spara Demand Management: Demand Control

"We use a very large amount of electricity during three critical months of the grape season; we wanted to get on top of this issue. We also wanted to do the right thing from a green perspective."

Many industrial businesses pay electricity bills that include a demand charge based on the peak rate of electrical flow during a billing cycle, measured in kilowatts (kW), in addition to a consumption charge for the amount of energy they use, measured in kilowatt hours (kWh). The demand charge is typically based on the highest average kW during a set interval (usually 15 minutes in the U.S.). This charge can account for 10 to 40 percent of the business’s bill.

Demand control involves preventing demand spikes, eliminating inefficiencies, and shifting power demand to the lowest-rate periods. Demand control through Spara DM™ can reduce demand charges by 10 to 30 percent, lowering the overall utility bill by 5 to 10 percent.

The technology works by using sophisticated load prediction and control algorithms, combined with customer-defined control rules and built-in intelligence on how to shed loads (called Embedded Operator Intelligence), to automate strategic demand reductions over a collection of loads while maintaining productivity.

Spara DM™ can prioritize loads sequentially, by group, or by conditions such as process status, type of material, time limits, or when a load was last curtailed. It can then orchestrate load shedding to achieve both savings and productivity targets. This level of control and precision is impossible for most facilities to achieve manually or with disparate automation systems.
