Load Factor Equation:
| From: | To: |
Load Factor is a measure of the utilization of electrical power systems, representing the ratio of average load to peak load over a specific period. It indicates how efficiently electrical capacity is being used.
The calculator uses the Load Factor equation:
Where:
Explanation: A higher load factor indicates more efficient use of electrical infrastructure, while a lower load factor suggests periods of high demand followed by periods of low utilization.
Details: Load factor calculation is crucial for utility companies, industrial facilities, and commercial buildings to optimize energy usage, reduce costs, and improve the efficiency of electrical systems.
Tips: Enter average load and peak load values in kW. Both values must be positive numbers, and peak load should be greater than or equal to average load for meaningful results.
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 poor utilization of electrical capacity.
Q2: 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, and reducing peak demand through load shedding or energy storage.
Q3: Why do utilities charge based on load factor?
A: Utilities often impose demand charges based on peak load to recover costs of maintaining capacity to meet maximum demand, encouraging customers to improve their load factor.
Q4: What's the difference between load factor and capacity factor?
A: Load factor measures utilization of electrical infrastructure, while capacity factor measures the actual output of a power plant compared to its maximum possible output.
Q5: Can load factor be greater than 100%?
A: No, load factor cannot exceed 100% as average load cannot exceed peak load by definition.
