For many commercial and industrial facilities, electricity costs depend on more than how much energy is consumed. Utilities may also assess a demand charge based on the facility’s highest level of electricity use during a specific billing period.
That means even a relatively short spike in demand can have an outsized effect on the monthly electric bill. Effective demand charge management focuses on identifying when those peaks occur and finding practical ways to keep them under control.
Understand When and Why Peak Demand Occurs
Peak demand often happens when multiple energy-intensive systems operate at the same time. Motors, HVAC equipment, production machinery, compressors, and other large electrical loads can combine to create a significant demand spike.
Understanding the facility’s load profile is an important first step toward peak demand reduction. Reviewing interval data, production schedules, and equipment operating patterns can help identify when peaks occur and which loads contribute to them.
Once those patterns are understood, businesses can consider energy management strategies such as:
- Staggering the startup of large motors and equipment
- Scheduling energy-intensive processes during off-peak periods
- Adjusting HVAC schedules where operations allow
- Avoiding unnecessary simultaneous loads
- Monitoring demand in real time to identify developing peaks
These changes can help reduce energy costs by changing when electricity is used rather than simply limiting production.
Take a More Active Approach to Demand Charge Management
Operational changes are useful, but facilities do not always have the flexibility to manually coordinate electrical loads throughout the day. Automated controls and energy-efficient technologies can help facilities manage these peaks more effectively.
Demand charge limiters can monitor facility demand and automatically control selected loads before electricity use exceeds a predetermined threshold. This gives businesses a way to respond to changing conditions in real time instead of discovering a costly demand spike after it has already occurred.
Facilities may also benefit from utility demand response programs. These programs encourage participating customers to decrease or shift electrical consumption during periods when demand on the grid is especially high. Program structures vary by utility, so businesses should evaluate the requirements and determine whether participation makes sense for their operations.
Build a Strategy Around Your Facility’s Actual Energy Use
There is no single approach to managing electricity demand charges. The right strategy depends on the facility’s equipment, production requirements, utility rate structure, and ability to shift or control loads.
Combining better energy-use data with operational changes and automated demand management can help businesses limit costly peaks while maintaining the power needed for production. A well-planned approach also makes it easier to identify where future efficiency improvements could provide the greatest value.
