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: 

\[ \text{Capacity Factor} = \frac{\text{Electricity Generation (MWh)}}{\text{Installed Capacity (MW)} \times 1000 \; (h)} \] Which one of the given technologies has the highest Capacity Factor?

• A. T1
• B. T2
• C. T3
• D. T4

Hint:

The capacity factor measures efficiency of utilization of installed capacity. Higher values mean the plant operates closer to its maximum potential.

Answer 1

The Correct Option is A

Step 1: Extract approximate data from the chart. - For T1: Installed $\approx 20$ MW, Generation $\approx 10000$ MWh 
- For T2: Installed $\approx 30$ MW, Generation $\approx 9000$ MWh 
- For T3: Installed $\approx 25$ MW, Generation $\approx 7000$ MWh 
- For T4: Installed $\approx 40$ MW, Generation $\approx 12000$ MWh 

Step 2: Compute Capacity Factors. \[ \text{CF} = \frac{\text{Generation}}{\text{Installed Capacity} \times 1000} \] - T1: $\dfrac{10000}{20 \times 1000} = 0.50 = 50\%$ 
- T2: $\dfrac{9000}{30 \times 1000} = 0.30 = 30\%$ 
- T3: $\dfrac{7000}{25 \times 1000} = 0.28 = 28\%$ 
- T4: $\dfrac{12000}{40 \times 1000} = 0.30 = 30\%$ 

Step 3: Identify the maximum. The highest capacity factor is for T1 at $50\%$. \[ \boxed{\text{T1}} \]
