From The Telegraph:
Sainsbury’s has cast doubt on the UK’s ability to keep the lights on, revealing it has built a string of new power plants for its supermarkets in part due to fears of a looming energy crunch.
Paul Crewe, a senior executive at the supermarket giant, said he had sleepless nights over energy security and feared UK electricity demand could soon outstrip supply.
The new gas-fired power generators – already supplying electricity for 10 supermarkets, and due to be built at a further six this year – would enable the stores to keep trading even in the event of a blackout, he said.
“It gives us energy security,” Mr Crewe said. “Energy security is extremely important, it keeps me awake at night if I’m honest thinking about it – especially as we use just under one per cent of power in the UK. We know UK grid infrastructure is at an extremely stretching period of time.”
