Peak Load: Peak load refers to the highest level of electrical demand recorded over a specific time period, which can influence infrastructure requirements and planning. Load factor is the ratio of the average load (or power usage) over a specific period to the peak load during that same period.
Demand Factor = Maximum demand of a system / Total connected load on the system. Demand factor is always less than one. For example, if a residence having 6000W equipment connected has a maximum demand of 300W, than demand factor = 6000W / 3300W = 55%. A high load factor means power usage is relatively constant. Low load factor shows

The Load Factor is a measure of the efficiency with which the electrical power is used. It is an essential concept in managing and planning electrical power systems, as it indicates how evenly the power is being consumed over a period. A higher load factor is generally seen as desirable because it means power usage is more constant, leading to
Solution: Load factor = (Energy consumed during a period)/ (Maximum demand x time under consideration) = 20kWhr/2kWx24hr=0.416=41.6% The curve drawn between the variations of load on the power station with reference to time is known as the load curve.
Electric Load Factor is a calculation used in the retail energy business to quickly determine the cost profile (cost to serve) for a particular account based on their energy consumption (kWh) in relation to their demand (kW).

With respect to reactive power losses on a system (kVAr and kVArh), although the area of reactive power is a signiifant issue for distribution network service providers it is not a parameter that is easily measured and does not form part of the normal revenue basis. Accordingly, it is not considered further in this
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load factor. An example, using a large commercial electrical bill:
Load factor calculation helps to improve the load factor. Load factor plays a key role in determining the overall cost per unit generated. The higher the load factor of the power station, the lesser will be the cost per unit generated. The ratio of average load to the maximum load during a given period is known as the load factor.
Capacitors will improve the power factor between the point of application and the power source, but leave the power factor between the load and the capacitor unchanged. Power factor correction capacitors can switch on every day when the inductive equipment starts. Switching a capacitor on can produce a very brief "over-voltage" condition.
Power Factor Definition: Power factor is defined as the ratio of real power used by a system to the apparent power transmitted through the circuit. (kVA) is equal to real power (kW). A load with a power factor of 1 is the most efficient loading of the supply. That said this is not realistic, and the power factor will in practice be less than 1.
