Correct Answer - Option 3 : 49%
Explanation:
Plant capacity factor:
- It is the ratio of actual energy produced to the maximum possible energy that could have been produced during a given period.
\(Plant\;capacity\;factor = \frac{{{\rm{Actual\;energy\;produced}}}}{{Maximum\;energy\;that\;could\;have\;been\;produced}}\)
\( = \frac{{Average\;demand \times T}}{{Plant\;capacity \times 100}}\)
\(= \frac{{Average\;demand}}{{Plant\;capacity}}\)
\(Annual\;plant\;capacity\;factor = \frac{{{\rm{Annual\;kWh\;output}}}}{{Plant\;capacity \times 8760}}\)
Calculation:
Given:
Annual output =150 × 106 kWh, plant capacity = 35 MW = 35000 W
\(Annual\;plant\;capacity\;factor = \frac{{{\rm{Annual\;kWh\;output}}}}{{Plant\;capacity \times 8760}}\)
\(Annual\;plant\;capacity\;factor = \frac{150 \times 10^6}{35000 \times 8760}\)
\(Annual\;plant\;capacity\;factor = 0.4892\)
Annual plant capacity factor = 0.49 = 49%
