1. What is the Cost of Coal per kWh?

The cost of coal per kWh represents the total cost to generate one kilowatt-hour of electricity from coal in Australia, including both the fuel cost and emissions-related costs.

2. How Does the Calculator Work?

The calculator uses the equation:

Where:

• \( Coal\ Price \) — Current coal price in Australian dollars per ton
• \( Efficiency \) — Energy conversion efficiency in kWh per ton of coal
• \( Emissions\ Cost \) — Additional costs related to carbon emissions in AUD per kWh

Explanation: The equation calculates the basic fuel cost per kWh and adds any emissions-related costs to determine the total cost of coal-generated electricity.

3. Importance of Cost Calculation

Details: Understanding the true cost of coal-generated electricity is crucial for energy planning, policy making, and comparing different energy sources in the Australian context.

4. Using the Calculator

Tips: Enter current coal price in AUD/ton, plant efficiency in kWh/ton, and any emissions costs in AUD/kWh. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical efficiency value for coal plants?
A: Modern coal plants typically achieve 2,500-3,500 kWh per ton of coal, while older plants may be less efficient.

Q2: How are emissions costs determined?
A: Emissions costs may include carbon pricing, pollution control costs, or estimated social costs of carbon emissions.

Q3: Why focus on Australian costs?
A: Coal prices and efficiency can vary by region due to coal quality, transportation costs, and local regulations.

Q4: How does this compare to renewable energy costs?
A: While coal has fuel costs, renewables typically have higher upfront capital costs but minimal operating costs.

Q5: Are there other costs not included here?
A: This calculator focuses on direct fuel and emissions costs. Additional costs might include capital, operation, and maintenance expenses.
