Question

The chart compares the Installed Capacity (MW) of four power generation technologies, T1, T2, T3, and T4, and their Electricity Generation (MWh) in 1000 hours. The Capacity Factor of a technology is defined as:

• A. T1
• B. T2
• C. T3
• D. T4

Hint:

To calculate the Capacity Factor, ensure consistent units (MW for capacity, MWh for generation, and hours for time). Compare values directly after substitution.

Answer 1

The Correct Option is A

Step 1: Understanding Capacity Factor. 
The capacity factor is the ratio of actual electricity generation to the maximum possible electricity generation over a given time. 

Step 2: Extract data from the chart. From the chart: T1: Electricity Generation = 14,000 MWh, Installed Capacity = 20 MW. T2: Electricity Generation = 9,000 MWh, Installed Capacity = 25 MW. T3: Electricity Generation = 8,000 MWh, Installed Capacity = 30 MW. T4: Electricity Generation = 7,000 MWh, Installed Capacity = 35 MW. 

Step 3: Calculate the Capacity Factor for each technology. 
Using the formula: \[ Capacity Factor} = \frac{Electricity Generation (MWh)}}{Installed Capacity (MW)} \times 1000}. \] T1: Capacity Factor = \(\frac{14,000}{20 \times 1000} = 0.7 \, (or 70\%)}\). T2: Capacity Factor = \(\frac{9,000}{25 \times 1000} = 0.36 \, (or 36\%)}\). T3: Capacity Factor = \(\frac{8,000}{30 \times 1000} = 0.267 \, (or 26.7\%)}\). T4: Capacity Factor = \(\frac{7,000}{35 \times 1000} = 0.2 \, (or 20\%)}\). 

Step 4: Conclusion. 
The highest Capacity Factor is for T1, which is 70\%.
