Question

The chart given below compares the Installed Capacity (MW) of four power generation technologies, T1, T2, T3, and T4, and their Electricity Generation (MWh) in a time of 1000 hours (h). The Capacity Factor of a power generation technology is: \[ \text{Capacity Factor} = \frac{\text{Electricity Generation (MWh)}}{\text{Installed Capacity (MW)} \times 1000 \, (\text{h})}. \] Which one of the given technologies has the highest Capacity Factor?

• A. T1
• B. T2
• C. T3
• D. T4
• E.

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: \begin{itemize} \item T1: Electricity Generation = 14,000 MWh, Installed Capacity = 20 MW. \item T2: Electricity Generation = 9,000 MWh, Installed Capacity = 25 MW. \item T3: Electricity Generation = 8,000 MWh, Installed Capacity = 30 MW. \item T4: Electricity Generation = 7,000 MWh, Installed Capacity = 35 MW. \end{itemize} Step 3: Calculate the Capacity Factor for each technology.
Using the formula: \[ \text{Capacity Factor} = \frac{\text{Electricity Generation (MWh)}}{\text{Installed Capacity (MW)} \times 1000}. \] \begin{itemize} \item T1: Capacity Factor = \(\frac{14,000}{20 \times 1000} = 0.7 \, \text{(or 70\%)}\). \item T2: Capacity Factor = \(\frac{9,000}{25 \times 1000} = 0.36 \, \text{(or 36\%)}\). \item T3: Capacity Factor = \(\frac{8,000}{30 \times 1000} = 0.267 \, \text{(or 26.7\%)}\). \item T4: Capacity Factor = \(\frac{7,000}{35 \times 1000} = 0.2 \, \text{(or 20\%)}\). \end{itemize} Step 4: Conclusion.
The highest Capacity Factor is for T1, which is 70\%.
