Households have been warned about the possibility of three-hour planned blackouts this winter. However, the National Grid Electricity System Operator (ESO) described the blackouts as being the "worst-case scenario" in a report last month.
But on Tuesday (Nov 22), fears rose after an alert from the ESO was issued - before being cancelled moments later. The warning said that due to "tight" capacity homes could lose power at around 7pm.
It wrote on Twitter: "The ESO has now withdrawn the Capacity Market Notice issued at 2:33pm today." Any forced cut off would most probably be in the evening, when power demand peaks.
