Keeping the lights on
Britain’s energy system has fallen victim to a cyber-attack targeting the IT infrastructure used to run the electricity market. The electricity system’s administrator, Elexon, confirmed that it was affected by a cyber-attack on Thursday afternoon but that the key systems used to govern the electricity market were not affected. National Grid is investigating whether the attack could affect the part of its business tasked with keeping the lights on.
