ESO Lightbulbs

Power Cut Statement - 9 August, 8pm

A National Grid ESO spokesperson said: “This evening we had an unexpected and unusual event, the loss of two generators that connect to the GB transmission system, which led to a fall in the frequency of the electricity system. Even though these events are outside of our control, we have plans in place to respond and the system operated as planned by disconnecting an isolated portion of electricity demand. We appreciate the inconvenience caused but this action allows the system to protect itself and limit the fall in frequency, allowing for power to be quickly restored. By 18:30 all demand was restored by the Distribution Network Operators. The system is operating normally."
