The Times | Back-up plants failed during blackouts, National Grid admits

Tom Edwards was cited in The Times discussing the blackout that occurred last month. According to National Grid, about 10 per cent of emergency back-up power supplies that were supposed to help avert blackouts last month failed to deliver electricity as expected.

Tom questioned whether there was “enough diversity in the provision”. National Grid has called for a review of whether security standards should be increased so it should hold more back-up power plants.

It appeared National Grid had been relying on batteries and small generators for the frequency response and did not appear to have had any pumped storage plants active.
