Marks: +1, -0

A power station has a maximum demand of 15,000 kW. The annual load factor is 50% and plant capacity factor is 40%. Determine the reserve capacity of the plant.

37.5 kW
3.75 MW
375 kW
37.5 MW

Validate

Solution:

Load factor

=\text " (Average Demand)"/ \text "(Maximum Demand)" = 0.5

Plant capacity factor

=\text " (Average Load)"/ \text "(Plant Capacity)" = 0.5/0.4

Plant capacity

= (0.5/0.4) × 15

= 18.75 MW
Reserve Capacity

= 18.75 - 15

= 3.75 MW
