Load Factor Formula:
| From: | To: |
Load Factor is a measure of the utilization of electrical power systems or equipment. It represents the ratio of average load to peak load over a specific period, typically expressed as a percentage. A higher load factor indicates more efficient use of electrical infrastructure.
The calculator uses the Load Factor formula:
Where:
Explanation: The formula calculates what percentage of the peak capacity is being utilized on average, indicating how efficiently electrical capacity is being used.
Details: Load factor is crucial for utility companies and large energy consumers to optimize energy usage, reduce costs, plan capacity requirements, and improve overall energy efficiency. A high load factor typically results in lower electricity costs per unit.
Tips: Enter both average load and peak load in kW. The average load must be less than or equal to the peak load. Both values must be positive numbers.
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 care about load factor?
A: Utilities use load factor to design their systems, set tariff structures, and encourage efficient energy use. Customers with higher load factors often receive better rates.
Q4: How is load factor different from demand factor?
A: Load factor measures utilization over time, while demand factor compares maximum demand to connected load. Both are important but measure different aspects of electrical system performance.
Q5: Can load factor exceed 100%?
A: No, load factor cannot exceed 100% as average load cannot be greater than peak load by definition.
