Chances are youâve experienced a blackout in the past, but what about a brownout? And what exactly is the difference between the two? We define a blackout as a complete power loss affecting many electric users over a large area for an extended period of time. Residents and businesses lose power and the entire area temporarily goes black. A brownout is a little different. Itâs a controlled power reduction or loss of electricity to pockets of customers. A brownout is caused by a state of âpoor power qualityâ in which a utility may reduce line voltage in order to deliver more electricity to meet increased demand.
