National Grid Transco can confirm that electricity was restored to its system at approximately 19:00 hrs this evening. We have done everything possible to protect the network and restore power as quickly as possible.
At 18:20 hrs alarms sounded on our system saying there was a fault and we automatically switched out that part of the network. This is a normal procedure under the circumstances. This resulted in a significant power cut in the South of London as we isolated the fault. We re-routed our power system and had power back into the area affected by 19:00 hrs.
We have worked closely with the local electricity company who had restored all its customers by 19:15 hrs.
At this stage we are investigating the cause and cannot speculate on what happened.
Ends.
Notes to Editors.
National Grid Transco operates the national electricity grid in England and Wales. It has invested some £3 billion in the electricity network over the last 10 years.
