Electric Load Factor Formula:
| From: | To: |
Electric Load Factor is a measure of the efficiency of electrical energy usage in a building. It represents the ratio of average load to peak load over a specific period, expressed as a percentage. A higher load factor indicates more efficient energy utilization.
The calculator uses the Load Factor formula:
Where:
Explanation: The load factor indicates how efficiently the building's electrical capacity is being utilized. A load factor of 100% would mean the building operates at peak load continuously.
Details: Calculating load factor helps building managers optimize energy consumption, reduce electricity costs, identify energy waste, and plan for capacity requirements. Utilities often charge higher rates for customers with low load factors.
Tips: Enter average load and peak load in kilowatts (kW). Both values must be positive numbers, and peak load must be greater than or equal to average load for valid calculation.
Q1: What is a good load factor for commercial buildings?
A: Typically, a load factor above 60% is considered good for commercial buildings, while industrial facilities may aim for 70-80% or higher.
Q2: How can I improve my building's load factor?
A: Strategies include load shifting (moving energy usage to off-peak hours), energy efficiency improvements, and implementing demand response programs.
Q3: What's the difference between load factor and demand factor?
A: Load factor compares average to peak load, while demand factor compares maximum demand to total connected load.
Q4: How does load factor affect electricity bills?
A: Many utilities include demand charges based on peak load. Improving load factor can significantly reduce these charges and overall electricity costs.
Q5: What time period should I use for calculation?
A: Typically calculated monthly, but can be calculated for any period (daily, weekly, annually) depending on your analysis needs.
