The UK has a high level of gas security, provided through our diverse range of gas supplies, including domestic production, pipeline imports from Norway and mainland EU, Liquefied Natural Gas (LNG) from global markets and storage. It is therefore misleading to talk about gas storage in terms of ‘days available’ because of this mix. Both physical system constraints and market processes mean storage could only be one part of the overall gas mix on any winter’s day.
Total gas infrastructure in GB can currently deliver around 700 million cubic meters a day, which is more than double average winter daily demand. Average winter demand is 290 million cubic meters a day and while storage amounts fluctuate, it is currently around 3500 million cubic meters.
