NESO highlighted an “emerging risk” to gas supply security due to potential premature closures of offshore pipeline infrastructure in the North Sea. <\/strong><\/p>\n\n\n\n

As UK Continental Shelf (UKCS) gas production rapidly declines\u2014accelerated by factors like high windfall taxes (Energy Profits Levy extended to 2030), limited new licensing, and low exploration activity (2025 was the worst year on record)\u2014key pipeline systems face low throughput.<\/strong><\/p>\n\n\n\n

On the same day that Rachel Reeves was announcing her Autumn Budget, the National Energy System Operator, NESO, quietly issued<\/a> a bombshell warning about the risks the UK might start running out of gas on cold winter days as a result of the possible closure of offshore pipeline infrastructure. National Gas has been warning about these risks for some time, saying privately they may manifest as early as next winter. NESO is more optimistic. I sit somewhere in between.<\/p>\n\n\n\n

The gas system in GB today depends on four main supply routes into the National Transmission System (\u201cNTS\u201d):<\/p>\n\n\n\n
