1. What is Diesel Generator Cost Per kWh?

The Diesel Generator Cost Per kWh calculation helps determine the operating cost of diesel generators in Malaysia. It considers fuel costs, generator efficiency, and maintenance expenses to provide the total cost per kilowatt-hour produced.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Fuel Cost \) — Current diesel price in RM per liter
• \( Efficiency \) — Generator's energy output in kWh per liter of diesel
• \( Maintenance \) — Maintenance cost in RM per kWh produced

Explanation: The equation calculates the fuel cost component by dividing fuel price by efficiency, then adds the maintenance cost per kWh to get the total operating cost.

3. Importance of Cost Calculation

Details: Accurate cost calculation is crucial for comparing generator operating costs with grid electricity, budgeting for off-grid operations, and making informed decisions about power generation options.

4. Using the Calculator

Tips: Enter current diesel price in RM/liter, your generator's efficiency in kWh/liter (check manufacturer specifications), and maintenance cost in RM/kWh. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical efficiency range for diesel generators?
A: Most diesel generators achieve 3-4 kWh per liter, but this varies by size, age, and load factor.

Q2: How do I determine maintenance costs?
A: Divide annual maintenance expenses by total annual kWh production. Typical range is RM0.01-RM0.05 per kWh.

Q3: Does this include capital costs?
A: No, this calculates only operating costs. For complete analysis, include generator depreciation.

Q4: How does load factor affect the calculation?
A: Generators are most efficient at 70-80% load. Lower loads decrease efficiency, increasing cost per kWh.

Q5: Where can I find current diesel prices in Malaysia?
A: Check MyPPP or Ministry of Domestic Trade and Consumer Affairs websites for updated fuel prices.
