The day’s electricity prices are split into 48 half hour periods, with a different “market driven” price set for each period. It has always been the case that under some circumstances one or more of the periods could be either zero cost or a negative cost (the generators pay people to use electricity). It can also go very high for one or more periods as well. It is only since the introduction of the smart meter that it has been possible to pass this on to the end customers, if that is what the meter operator decides to do.
