Energy demand management activities attempt to bring the electricity demand and supply closer to a perceived optimum, and help give electricity end users benefits for reducing their demand. In the modern system, the integrated approach to demand-side management is becoming increasingly common.
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.
Demand response, a type of energy demand management, seeks to adjust in real-time the demand for power instead of adjusting the supply. Utilities may signal demand requests to their customers in a variety of ways, including simple off-peak metering, in which power is cheaper at certain times of the day, and smart metering , in which explicit ...
Energy demand management, also known as demand-side management (DSM) or demand-side response (DSR), is the modification of consumer demand for energy through various methods such as financial incentives and behavioral change through education.
The 1970s energy crisis ended a period of relatively stable energy prices and stable supply-demand relation. Concepts of demand side management, least cost planning and integrated resource planning (IRP) emerged with new emphasis on the need to reduce energy demand by new technologies or simple energy saving.

The main goal of SEM is to help a company achieve continuous improvement in its energy performance over a longer-term period. Some energy benefits of SEM include reduced energy consumption through improved energy efficiency and energy conservation, improved peak demand management and reduced demand charges, decreased overall energy cost, reduced energy costs, greenhouse gas (GHG) emissions and ...
The first two definitions allow for demand-side measures, including daylighting, retrofitted building insulation, and passive solar building design, as well as socio-economic factors, such as aspects of energy demand management and remote work, while the third does not.
Vehicle-to-grid is a system under development allowing electric cars to provide power to the grid at times of high demand, low supply from e.g. wind and solar power and therefore high prices, and charge the car again when the price is lower, based on the energy need the car owner has defined in the car settings (such as need for long distance ...
