Load management actively controls electricity consumption to reduce the load on the grid. Electricity customers with RLM must pay surcharges for load peaks. It is not the frequency of the peaks that is decisive, but the maximum ¼ h value that is reached in the month or year. There is a willingness to limit the maximum peak, as this represents a significant cost factor in the electricity bill in some cases. During periods of high demand, consumers that are not absolutely necessary must be switched off. Heat pumps, electric storage heaters or batteries of electric cars, for example, are suitable for load management. Since the increased use of renewable energies means that electricity production fluctuates greatly depending on the weather, in the future load management will no longer have to serve demand that is as uniform as possible, but rather demand that follows the variable supply.
