1. What is Generator Cost per kWh?

Definition: This calculator determines the cost to generate one kilowatt-hour (kWh) of electricity based on fuel expenses and energy output.

Purpose: It helps individuals and businesses evaluate the operating costs of generators and compare different power generation options.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_{kWh} \) — Cost per kilowatt-hour ($/kWh or £/kWh)
• \( C_f \) — Total fuel cost ($ or £)
• \( E_{kWh} \) — Energy produced in kilowatt-hours (kWh)

Explanation: The total fuel cost is divided by the total energy produced to determine the cost per unit of electricity generated.

3. Importance of Cost per kWh Calculation

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

4. Using the Calculator

Tips: Enter the total fuel cost and the total energy produced by the generator. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's included in fuel cost?
A: Include all expenses related to the fuel used (purchase price, delivery, taxes) but exclude generator maintenance and capital costs.

Q2: How do I measure energy produced?
A: Use a kWh meter on the generator output or calculate from generator specifications and runtime.

Q3: What's a typical cost per kWh for generators?
A: Diesel generators typically range $0.15-$0.30/kWh, while natural gas might be $0.10-$0.20/kWh, varying with fuel prices.

Q4: Does this include generator efficiency?
A: Efficiency is reflected in the energy output (kWh) relative to fuel input, so no separate efficiency factor is needed.

Q5: Can I use this for solar or wind systems?
A: This formula works for any energy system where you can measure fuel costs and energy output.
