1. What is Cost per kWh for Diesel Generator?

Definition: This calculator estimates the electricity production cost for diesel generators based on fuel consumption and fuel price.

Purpose: Helps businesses and individuals evaluate the operational costs of diesel generators and compare with other power sources.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_{kWh} \) — Cost per kilowatt-hour ($/kWh or ₱/kWh)
• \( Q_f \) — Fuel consumption rate (L/kWh)
• \( C_{fuel} \) — Fuel cost per liter ($/L or ₱/L)
• \( E_{kWh} \) — Energy output (kWh, typically 1 for per unit calculation)

Explanation: The formula calculates how much it costs to produce one kWh of electricity from a diesel generator.

3. Importance of Cost Calculation

Details: Understanding generator operating costs helps in budgeting, comparing power sources, and optimizing energy usage.

4. Using the Calculator

Tips: Enter fuel consumption (default 0.3 L/kWh), current fuel price, and energy output (typically 1 kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical fuel consumption rate?
A: Most diesel generators consume 0.2–0.4 liters per kWh, depending on size and efficiency.

Q2: Should I include maintenance costs?
A: This calculates only fuel costs. For total cost, add maintenance (typically $0.01–$0.05/kWh).

Q3: How does generator load affect consumption?
A: Consumption increases with load. Values are typically given for 75-100% load.

Q4: Why keep energy output at 1 kWh?
A: This gives cost per unit. Change only if calculating for different output quantities.

Q5: How does this compare to grid electricity?
A: Diesel typically costs 2-3× more than grid power but provides reliability during outages.
