Answer / zan

In electrical engineering, load factor is the average power
divided by the peak power, over a period of time. The peak
may be a theoretical maximum, rather than a measured
maximum.
In the electricity industry, load factor is a measure of
the output of a power plant compared to the maximum output
it could produce.
The two commonest definitions are:
• the ratio of average load to capacity
• The ratio of average load to peak load in a period.
Assuming the first definition, a higher load factor is
better:
• A power plant may be less efficient at low load
factors.
• A high load factor means fixed costs are spread
over more kWh of output.
• A high load factor means greater total output.

Answer / p.subash

Load factor for a power plant is the ratio between average
load and peak load and can be expressed as
μlf = (100) Pal / Ppl
where
μlf = load factor (%)
Ppl = peak load for the power plant in the period (kW)
