Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government, further to the Written Answers by Lord Henley on 20 February (HL13575) and on 26 June (HL16396), and following the closure of the Rough gas storage facility, what assessment they have made of whether storing an average of seven days of UK natural gas consumption is a sufficient reserve to cope with any unexpected interruption of global gas supply.

Government has published several assessments regarding the UK’s security of gas supply. The assessments include: CEPA’s Security of Supply report (2017), the Strategic Assessment and Review by BEIS (2017) and the UK National Risk Assessment on Security of Supply (2018), as well as the annual Statutory Security of Supply Report (most recent, 2018).

These assessments conclude that current and forecast levels of GB supply and storage infrastructure are sufficient to meet demand in all but the most extreme cases of supply disruption.
