Centrica warns of UK gas storage closure as 2030 supply risks mount
Centrica’s threat to shut Britain’s largest gas storage site without state backing exposes severe vulnerabilities in the UK energy network that could trigger price spikes across European markets.
Centrica has warned it will close the Rough gas storage facility off the Yorkshire coast next April unless the UK government agrees to back a £2bn expansion. The British Gas owner is already halting gas injections at the site for the upcoming winter, making the threat immediate.
Chief executive Chris O’Shea argued the situation transcends corporate economics. “I think this [Rough] is essential for the UK energy security,” he stated, insisting the choice to keep it open is “really a decision for government now” and calling claims of a purely commercial motive “patently not true”.
The economics of gas storage rely on narrow winter and summer price spreads, making a £2bn investment unviable without a regulated return. While a disruption in the Strait of Hormuz recently generated a £57m top-line profit for the facility, the previous year saw near-identical losses.
This commercial standoff highlights a broader systemic vulnerability mapped out by the National Energy System Operator. The government adviser recently warned that losing a single major piece of infrastructure, such as the 725-mile Langeled pipeline from Norway, during a cold snap would cause supply to fall short of demand in 2030-31.
For European energy markets, the UK storage deficit poses a tangible risk of cross-border price volatility. Britain typically relies on continental storage during cold months, but European reserves are projected to remain low following the Hormuz disruption, increasing the likelihood of severe winter price spikes.
The Rough facility itself faces structural criticisms, with industry experts describing it as a large storage volume with slow extraction capabilities. The government must now decide whether to re-engineer the site or pivot toward on-shore salt caverns, expanded continental interconnectors, or new liquefied natural gas terminals to replace its current three.
Domestic production remains a critical variable in this equation, with the proposed Jackdaw gasfield alone capable of supplying 6% of national output. Gas still met 35% of total UK energy demand in 2024, and 24m households remain connected to the network, ensuring demand will persist long after renewable electricity targets are met.
Energy secretary Miatta Fahnbulleh now faces an urgent dual mandate to secure short-term winter supplies and draft a long-term transition strategy. An interim government response to the ongoing gas system review is expected within weeks, though building alternative infrastructure will take considerable time.
