Blackouts and Brownouts

A blackout is generally the most significant form of power disruption, a large-scale service interruption that sees your grid supply cut off. Blackouts can be caused by a variety of outside factors, such as severe weathers or unexpected spikes in demand.

Put simply, blackouts occur when there is an imbalance between generation capacity and demand. While the majority are relatively brief, even a short blackout can cause severe disruption to a business’s operations and productivity.

One method employed to avoid blackouts is by intentionally throttling electricity supply to a certain area. These dips in supply are known as brownouts, where homes and businesses continue to be supplied with electricity, but at a lower voltage.

This technique takes its name from the dimming of incandescent light bulbs that frequently marks a brownout. In some cases, a brownout can be triggered unintentionally due to equipment malfunction on the grid, but this is rare.
