British Gas owner Centrica has reopened its giant gas storage facility to boost the UK’s supply over the winter.
The energy firm said site would allow for “cheaper gas” to be stored for the colder months and help “reduce or stabilise costs” for households.
Earlier this month, the UK energy regulator said homes could face power cuts of up to three hours if gas supplies run low.
Centrica said reopening Rough was “not a silver bullet for energy security”.
But it said: “It is a key part of a range of steps which can be taken to help the UK this winter.”
