1. What is Cost of Diesel Generator per kWh?

Definition: This calculator estimates the cost to generate one kilowatt-hour (kWh) of electricity using a diesel generator.

Purpose: It helps businesses, homeowners, and project managers evaluate the operating costs of diesel generators for power generation.

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 (gallons per kWh)
• \( C_{fuel} \) — Cost of diesel fuel ($/gallon or ₱/gallon)
• \( E_{kWh} \) — Energy output (kWh, typically 1 for per-unit calculation)

Explanation: The formula multiplies fuel consumption by fuel cost to get total fuel expense, then divides by energy output to determine cost per unit of electricity.

3. Importance of Cost Calculation

Details: Understanding generator operating costs helps in budgeting, comparing power sources, and making informed decisions about energy use.

4. Using the Calculator

Tips: Enter the generator's fuel consumption rate (default 0.07 gal/kWh), current diesel fuel cost, and energy output (default 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 0.05-0.1 gallons per kWh, with 0.07 gal/kWh being common for mid-sized units.

Q2: Does this include maintenance costs?
A: No, this calculates only fuel costs. Add 10-20% for maintenance to get total operating costs.

Q3: How does load affect consumption?
A: Generators are most efficient at 70-80% load. Consumption increases at lower loads.

Q4: Can I use this for other fuel types?
A: Yes, but you'll need the appropriate consumption rate and fuel cost for gasoline, propane, etc.

Q5: How accurate is this calculation?
A: It provides a good estimate, but actual costs vary with generator efficiency, age, and operating conditions.
