What is load shedding?
Load shedding is the operation of temporarily reducing the supply of electricity to an area, to avoid overloading the generators.
As explained elsewhere, a generator cannot take 100% of its load in one go. This would cause the frequency and voltage to drop too much. This generally means, you have to oversize the generator, so that it can comfortably accommodate the initial site load. This can at times be expensive.
It is possible however to avoid this cost by implementing load shedding. This involves putting a delay on some of the circuits within the building. The initial load on the generator is therefore within the acceptable limits.
With load shedding, you will notice a slightly longer period between the power cut and the time of the last circuit connected to the generator. This would only be a matter of seconds and therefore not detrimental. Additionally, it would make sense to delay the connection of a UPS to the generator as the battery backup will provide the uninterrupted power throughout.
Depending on your power infrastructure setup and the size of generator you require, load shedding may or may not be cost effective. We can discuss this with you to provide the best solution.
