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 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 ...
MSP kWh is the amount of electricity consumed at the 'meter supply point', which is the customer's meter. GSP kWh is obtained by multiplying the MSP kWh by the Line Loss Factor (LLF, a figure > 1) to include the amount of electricity lost when it is conducted through the distribution network, from the 'grid supply point' to the customer's meter.
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval. Electric utilities use electric meters installed at customers' premises for billing and monitoring purposes.
At this time there is a combination of office, domestic demand and at some times of the year, the fall of darkness. [2] Some utilities will charge customers based on their individual peak demand. The highest demand during each month or even a single 15 to 30 minute period of highest use in the previous year may be used to calculate charges. [3]
Any Metering System where the average of the maximum monthly electrical demands in the three months of highest demand, either in: a. the previous twelve months; or b. the period since the most recent Significant Change of Demand (whichever is the shorter) exceeds 100kW.
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.
