The United Kingdom faces potential fuel shortages this winter as gas storage levels have dropped to historically low levels, Centrica’s Chief Executive Officer, Chris O’Shea, warned on Friday. Speaking about the country’s energy preparedness, O’Shea said Britain currently has “almost no gas in storage” for the coming winter, describing the situation as a “huge concern” for both energy and national security.
Data shows that UK gas storage facilities are approximately 30 percent full this week, a significant decline compared to 46 percent at the same time last year and over 90 percent levels recorded two years ago. This represents the lowest recorded storage levels for August since records began, according to market data. Contributing to the tight supply is disrupted global energy shipping, largely due to reduced tanker traffic through the Strait of Hormuz following recent US-Israeli strikes on Iran. The strait typically accounts for about 20 percent of the world’s oil and gas shipping.
O’Shea emphasized that the UK’s reliance on energy imports and insufficient investment in domestic gas storage and power generation have left the country vulnerable. “For too long we in the UK have relied on other countries to provide our energy security,” he said, justifying the call to renew efforts in developing storage capacity and power infrastructure.
The issue follows announcements from Norway, a major gas supplier to Europe, where the energy minister declared the country unwilling to continue serving as “the battery of Europe,” signaling a reduction in its role as a dependable energy partner. O’Shea described this shift as understandable, underscoring the UK’s need to enhance its own energy resilience.
Low gas reserves increase the risk of higher wholesale prices for energy imports, which are generally passed on to consumers. However, analysts note that the UK’s energy system remains less dependent on gas storage than some European nations, many of which maintain strategic reserves and operate with less diversified energy supplies.
To address the situation, Centrica has urged the UK government to back a £2 billion redevelopment plan for the Rough offshore gas storage facility. Originally closed in 2017 due to high maintenance costs, Rough was reopened in 2022 amid surging energy prices following the COVID-19 pandemic. A spokesperson for the Department for Energy Security and Net Zero (DESNZ) said decisions about the future of Rough remain commercial matters for Centrica but confirmed that the government is open to proposals that offer value for taxpayers.
The department also highlighted the UK’s current energy mix, which includes gas sourced from the North Sea, pipeline connections with Norway, interconnectors to Europe, and three liquefied natural gas (LNG) terminals. Despite these resources, the ongoing conflict in the Middle East and broader geopolitical challenges continue to pressure gas markets.
Earlier this week, the energy regulator Ofgem raised its price cap on household energy bills by 4 percent, bringing the average annual cost for gas and electricity to £1,723, an increase of about £60. The combination of elevated prices and limited storage capacity points to a challenging winter energy outlook for the UK.
