Equinor, Centrica Strike 10-Year UK Gas Supply Agreement

In This Article:

Equinor ASA EQNR, the Norwegian energy giant, and Centrica plc, owner of British Gas, have inked a £20 billion gas supply agreement for 10 years starting Oct. 1, 2025. Under the terms of the deal, Equinor will supply 55 terawatt-hours (TWh) of natural gas annually, equivalent to around 5 billion cubic meters, meeting nearly 10% of the UK’s total gas demand.

The agreement, priced at market rates, stands out as one of the largest bilateral gas supply deals in Equinor’s portfolio and marks a milestone in the UK’s efforts to stabilize energy supplies amid geopolitical uncertainty and the ongoing energy transition.

As Europe continues to adjust to the decline in Russian gas exports, the UK has increasingly leaned on Norway, which already accounts for around two-thirds of Britain’s gas supply, with Equinor being the dominant supplier. This long-term agreement ensures a stable gas flow from the Norwegian Continental Shelf, giving the UK a critical buffer against market volatility and supply disruptions, especially as the country prepares for future winter demands.

Equinor CEO Anders Opedal highlighted that the agreement supports both energy reliability and decarbonization efforts, noting the flexible and strategic role of natural gas in the energy transition. He also underscored the UK’s position as a key and longstanding partner for Equinor.

Centrica’s CEO Chris O’Shea called the deal a “significant investment in the UK’s future,” positioning natural gas as a key bridge fuel that supports both current energy needs and emerging low-carbon technologies like hydrogen and carbon capture.

With energy markets still grappling with the fallout of Russia’s supply cuts, long-term gas contracts are regaining favor among utilities and governments aiming to hedge against price spikes and ensure continuity. For Centrica, this deal complements efforts to strengthen domestic infrastructure, including gas storage, while maintaining flexibility during the energy transition.

At the same time, the agreement aligns with the UK’s push for energy resilience without undermining climate commitments. O’Shea also indicated that Centrica plans to collaborate with the government on expanding national gas storage capacity, further enhancing the country’s energy security.

Beyond conventional gas supply, Equinor is playing a leading role in the UK’s shift toward a low-carbon future. The company already operates three offshore wind farms, including Hywind Scotland, the world’s first floating wind facility, and is developing Dogger Bank, which is on track to become the world’s largest offshore wind farm.
