Maximum Demand Indicator (MDI) is an instrument for measuring the maximum amount [clarification needed] of electrical energy required by a specific consumer during a given period of time. [1] MDI instruments record the base load requirement of electrical energy .
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] 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 ...
In a power system, a load curve or load profile is a chart illustrating the variation in demand/electrical load over a specific time. Generation companies use this information to plan how much power they will need to generate at any given time. A load duration curve is similar to a load curve. The information is the same but is presented in a ...
In telecommunications, electronics and the electrical power industry, the term demand factor is used to refer to the fractional amount of some quantity being used relative to the maximum amount that could be used by the same system. The demand factor is always less than or equal to one.
The unofficial term diversity, as distinguished from diversity factor, refers to the percent of time available that a machine, piece of equipment, or facility has its maximum or nominal load or demand; a 70% diversity means that the device in question operates at its nominal or maximum load level 70% of the time that it is connected and turned on.

Typical daily consumption of electrical power in Germany, outdated (2005) Peak demand may exceed the maximum supply levels that the electrical power industry can generate, resulting in power outages and load shedding. This often occurs during heat waves when use of air conditioners and powered fans raises the rate of energy consumption ...
The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy , such as wind, the sun or ...
