National Grid has pointed to a lightning strike as being partly to blame for a major grid outage that plunged more than a million people into darkness earlier this month. According to a hotly anticipated draft report released by the grid operator today, a lightning strike on the transmission circuit at 4:52pm on Friday August 9 immediately preceded a loss of power from a major gas power plant and an offshore wind farm. The resulting loss of generation on the system caused power cuts both for homes and businesses, and also cut power to critical infrastructure such as hospitals and railways. The report appears to contradict comments made by National Grid’s CEO John Pettigrew last week, who told The Times that lightning strikes are a regular occurence on the grid, and strikes on August 9 were not the reason the generators tripped offline. However, today’s report states that the lightning strike was “associated” with the outages at the gas and wind plants.

The FTSE 100 company confirmed that the August 9 power cuts, which left a million homes without electricity and caused havoc on rail networks, were triggered by lightning strikes.
