What is load shedding?

As explained elsewhere, a generator cannot take 100% of its load in one go as this would cause the frequency and voltage to drop too much. This generally means that 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 by implementing load shedding. This involves putting a delay on some of the circuits within the building so that the initial load on the generator is within the acceptable limits. With load shedding, all you will notice is a slightly longer period between the power cut and the time the last circuit is 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.
