THE head of the National Grid has warned that blackouts could be imposed between 4pm and 7pm on “really, really cold” winter weekdays if gas imports are reduced.
John Pettigrew, the National Grid chief, said blackouts would be in place during the “deepest darkest evenings” in January and February should electricity generators not have enough gas to meet demand.
His comments came at the Financial Times’s Energy Transition Summit on Monday.
