High load factor indicates

cost of generation per unit power is increased
total plant capacity is utilised for most of the time
total plant capacity is not properly utilised for most of the time
none of the above

The correct answer is: B. total plant capacity is utilised for most of the time.

A high load factor indicates that a power plant is being used efficiently. This means that the plant is generating the most power possible for the amount of fuel it is using. A high load factor is important because it can save money on fuel costs and reduce pollution.

A low load factor indicates that a power plant is not being used efficiently. This means that the plant is generating less power than it could be for the amount of fuel it is using. A low load factor can be expensive and harmful to the environment.

Here is a brief explanation of each option:

  • Option A: cost of generation per unit power is increased. This is not necessarily true. A high load factor can actually lead to lower costs per unit of power generated, because the plant is using less fuel overall.
  • Option B: total plant capacity is utilised for most of the time. This is the correct answer. A high load factor indicates that the plant is being used efficiently.
  • Option C: total plant capacity is not properly utilised for most of the time. This is not necessarily true. A low load factor can indicate that the plant is not being used efficiently, but it can also be due to factors outside of the plant’s control, such as low demand for electricity.
