Load Factor Formula:
| From: | To: |
The Electric Load Factor is a measure of the efficiency of electrical energy usage, representing the ratio of average load to peak load over a specific period. It indicates how consistently electrical power is being used.
The calculator uses the Load Factor formula:
Where:
Explanation: The formula calculates what percentage of the peak load is being utilized on average, providing insight into energy usage efficiency.
Details: Load factor calculation is crucial for energy management, cost optimization, and infrastructure planning. A higher load factor indicates more efficient energy usage and can lead to lower electricity costs.
Tips: Enter average load and peak load values in kW. Both values must be positive numbers, with peak load greater than zero and average load not exceeding peak load.
Q1: What is a good load factor value?
A: Generally, a load factor above 75% is considered excellent, 50-75% is good, and below 50% indicates inefficient energy usage with significant peak demand spikes.
Q2: How can I improve my load factor?
A: Load factor can be improved by shifting non-essential operations to off-peak hours, implementing energy storage systems, or using demand response strategies.
Q3: What's the difference between load factor and power factor?
A: Load factor measures utilization efficiency (average vs peak usage), while power factor measures the efficiency of power delivery (real power vs apparent power).
Q4: How is load factor used in utility billing?
A: Many utilities use load factor in their rate structures, with higher load factors often qualifying for better rates due to more consistent and predictable demand.
Q5: Can load factor be greater than 100%?
A: No, load factor cannot exceed 100% since average load cannot be greater than peak load by definition.
