1. What is Load Factor?

Load Factor is a measure of the efficiency of electrical energy usage, calculated as the ratio of average load to peak load over a specific period. It indicates how well the electrical capacity is being utilized.

2. How Does the Calculator Work?

The calculator uses the Load Factor formula:

Where:

• Average Load — The average power consumption over a period (kW)
• Peak Load — The maximum power demand during that period (kW)

Explanation: The formula calculates what percentage of the peak load is being used on average, with higher percentages indicating better utilization of electrical capacity.

3. Importance of Load Factor Calculation

Details: Load factor is crucial for energy management, utility billing, capacity planning, and identifying opportunities for energy efficiency improvements. A higher load factor typically results in lower energy costs per unit.

4. Using the Calculator

Tips: Enter both average load and peak load in kilowatts (kW). Both values must be positive numbers, with peak load greater than or equal to average load.

5. Frequently Asked Questions (FAQ)

Q1: What is a good load factor value?
A: Generally, a load factor above 75% is considered good, indicating efficient use of electrical capacity. Values below 50% may indicate poor utilization.

Q2: How does load factor affect electricity bills?
A: Many utility companies charge demand charges based on peak load. A higher load factor can reduce these charges and lower the overall cost per kWh.

Q3: Can load factor be greater than 100%?
A: No, load factor cannot exceed 100% as average load cannot be greater than peak load by definition.

Q4: What time period is used for load factor calculation?
A: Load factor is typically calculated over a billing period (usually one month) but can be calculated for any defined period.

Q5: How can I improve my load factor?
A: Load factor can be improved by shifting energy usage to off-peak hours, implementing energy management systems, or using energy storage to reduce peak demand.
