1. What is Plant Factor Capacity (PFC)?

Definition: PFC measures the actual output of a power plant compared to its maximum potential output over a period.

Purpose: It helps evaluate a plant's operational efficiency and capacity utilization.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( PFC \) — Plant Factor Capacity (percentage)
• \( Actual \) — Actual energy output (kWh)
• \( Potential \) — Maximum potential output (kW × hours)

Explanation: The ratio of actual to potential output shows what percentage of the plant's capacity is being utilized.

3. Importance of PFC Calculation

Details: PFC helps in assessing plant performance, maintenance needs, and operational efficiency. Higher PFC indicates better utilization.

4. Using the Calculator

Tips: Enter the actual energy output in kWh and potential output in kW × hours. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a good PFC value?
A: Typically 60-85% for most plants, but varies by plant type and operational strategy.

Q2: How is potential output calculated?
A: Multiply the plant's rated capacity (kW) by the number of operational hours.

Q3: What causes low PFC?
A: Maintenance downtime, reduced demand, equipment failures, or operational constraints.

Q4: How often should PFC be calculated?
A: Typically calculated monthly or annually for performance analysis.

Q5: Can PFC exceed 100%?
A: Normally no, unless the plant operates above its rated capacity temporarily.
