The resilience of Britain’s electricity system may need to be improved in the wake of the worst blackouts in a decade, National Grid has admitted. The FTSE 100 group yesterday called for a review of security standards to assess whether it should hold more back-up power plants and said that work to prevent small power plants failing may need to be accelerated. It revealed fresh details of the recent blackouts, including the failure of a valve at a gas power plant and problems with factory settings on Siemens Gamesa wind turbines. More than a million homes were left without power in the blackouts on August 9, which triggered chaos on the rail networks, with 23 trains being evacuated and hundreds cancelled. National Grid blamed most of the transport disruption on incorrect settings on Siemens trains. National Grid is Britain’s electricity system operator, running the control room that is responsible for keeping the lights on. It is under investigation by Ofgem, the industry regulator, over the August blackouts, along with all other energy companies involved in the incident, but insists that its control room did nothing wrong.
