Critical infrastructure including major hospitals, water treatment facilities and military sites would be protected.\n\nUnder the system, electricity demand is divided into blocks that can be disconnected and rotated around the country. Depending on the severity of a shortage, multiple areas could lose power simultaneously.\n\n**Ofgem** backed the changes, arguing that rotating outages would improve system resilience and distribute disruption more fairly.\n\nThe move comes amid increased scrutiny of Britain’s electricity network and the challenges of balancing supply as variable wind and solar generation accounts for a growing proportion of the energy mix.\n\nNESO stressed that the protocol is designed only for **“the most extreme and unlikely circumstances”**, while the Government said it remains confident in Britain’s security of electricity supply."}
