When the supplying company receives more demand for electrical power than its generating or transmission or installed capacity can deliver, the company has to resort to rationing of the available electricity to its customers. This act is called load shedding.

Load shedding can also be referred to as Demand Side Management or Load Management

<><><>

Demand Controller devices are used to shed loads when a pre-set Kw reading has been reached.

These devices are tied in to circuits supplying electric heat, stoves, dryers, hot tubs--anything that tends to use a lot of power. When set properly, Demand Controllers can be very effective at reducing your energy bill.

This question may be referring to the kind of load shedding which often occurs in places where the total electrical power load which can be taken by consumers greatly exceeds the available amount of energy which can be generated by the local power station or national network of power stations. This is a situation which is common in many developing countries. As soon as total power demanded exceeds a certain percentage - usually 98% - of the maximum possible power that can be generated, parts of the distribution network have to be disconnected. Such disconnections are known as "load shedding".

If loadshedding was not done the generating equipment's overload breakers would automatically shut down the whole power station to protect its alternators (electrical generators) from very severe damage. Such damage would be extremely expensive to repair and would take a lot of time to do.

So in practice, to keep the power stations running 24/7 under such conditions, loadshedding is applied to different parts of the distribution network at various set times throughout a regular "power availability" period of, usually, a week. For example, parts of the network supplying homes and small business offices may only get power for two or three hours at a time every day or every other day, whilst important places - such as hospitals, major factories and, typically, government offices - may get power almost 24/7.

<><><>

Load shedding, normally used in industrial, large commercial, and utility operations, is monitoring electric usage continuously (usually by automated instrumentation) and shutting down certain pre-arranged electric loads or devices if a certain upper threshold of electric usage is approached. there are two reasons for doing it, both of them financially motivated.

Power companies sometimes set up an industrial customer or a school with an electric billing rate in steps, i.e. if you are pulling less than this amount of electric current during certain times you get billed at one rate for the electricity you use. If you are pulling MORE than this amount of electric current during that time, you get billed at a higher rate, even if you use the same amount of electricity overall. The highest current you draw during the time period in question is your "peak demand". The power company has to have generating capacity built and in place to generate the sum of all of the "peak demands" of its customers during the highest peak demand period. Say that period is 10 am to 12 am during weekdays. If the highest peak demand exceeds the capacity of the power company to generate, they either have to build another power station to cover that 2 hour period each day, which is a waste of money, or they have to buy power from some other power company during those 2 hours which is also expensive. So power companies look for ways to cut down on the highest peak demand. They encourage their large customers to cut back on peak demand during those "highest peak demand periods" by charging them more if they exceed a certain peak demand. Customers can stay below this set peak demand limit by monitoring their electric demand and cutting off unnecessary electric loads if they get too close to their demand limit. That is one form of load shedding.

The other way is for the power companies to ask their small customers for permission to install a piece of equipment in their home or business and wire one or two appliances to the equipment which will shut down the appliances based on a radio signal from the power company. The appliances are usually electric water heaters. The power company gives a discount to these customers. Then, if the power company sees that it's demand is coming close to its generating capacity, it sends out a signal and cuts off all these appliances. That is also called load shedding.
