Load Curves
The curve showing the variation of load on the power station (power plant) with reference to time is known as load curve.

Maximum Load (Peak Load)
It represents the maximum power that consumed by the load during a specific given time. It is also equal to the maximum actual power generated by the plant when the transmission losses are neglected.

Average Load
It is the average power that consumed by the load during a certain period of time and it is equal to the average power that generated by the plant during the same period of time when neglecting transmission line losses.

Average Load=(Area under the load curve (kWh))/(no.of hours (h)) (kW)

Load Factor
It is the ratio of the average load to the maximum load for a certain period of time. The load factor is called daily load factor if the period of time is a day, and if the period of time is a month, the load factor is called monthly load factor, and similarly for the year load factor.
