Grain LNG has launched a formal Expression of Interest inviting market participants to register for regasification capacity at its UK terminal, with availability expected from October 2029 as existing long-term contracts expire. The capacity on offer includes approximately 200,000 m³ of LNG storage and 125 GWh/day of regasification capacity — around 3 million tpy — along with associated berthing rights. Responses are due by July 15, 2026.
Grain LNG invites market interest in 2029 capacity
The EOI is open to all market participants and seeks non-binding indications of interest. Companies aren’t committing to anything by responding — they’re simply signaling their appetite for capacity and sharing feedback on how Grain LNG structures its offering.
Rather than designing a capacity package in isolation, the terminal is inviting potential customers to shape the outcome from the outset. The process exists to help Grain LNG understand what the market actually needs before any final product is locked in.
After the July 15, 2026 deadline, Grain LNG will review all responses and use them to inform its final product offering.
Capacity availability driven by expiring long-term contracts
The timing of this EOI is directly tied to the lifecycle of existing agreements at the terminal. Capacity is becoming available from October 2029 as current long-term contracts reach their end—a natural opening for new market participants, or existing ones, to secure access.
The scale of what’s on offer is considerable: approximately 200,000 m³ of LNG storage, 125 GWh/day of regasification capacity equating to roughly 3 million tonnes per year, and associated berthing rights. Taken together, this is a comprehensive infrastructure package rather than a partial service.
For companies looking to establish or expand long-term positions in the UK gas market, access to existing, operational infrastructure at one of the country’s primary LNG import points doesn’t come up often.
Multiple product structures under consideration to enhance flexibility
Grain LNG isn’t approaching this process with a fixed product in mind. Structures currently under exploration include a full capacity award to a single party, split capacity supported by a sharing arrangement, and joint bid structures that would allow multiple participants to collaborate.
The capacity sharing arrangement deserves particular attention. It’s specifically intended to support alternative product structures and improve flexibility—an acknowledgment that different market participants carry different needs and risk appetites. Grain LNG is explicitly asking for feedback on this element, which suggests the final design will be responsive to what respondents say rather than predetermined. Companies that engage have a genuine opportunity to influence how capacity is ultimately packaged.
Grain LNG’s role in UK energy security and next steps
Grain LNG occupies a significant position in the UK’s energy infrastructure. As Europe’s largest LNG import terminal, it supports domestic security of supply and provides flexible access to global LNG markets—a function that has carried added weight as European energy markets have adjusted to supply disruptions in recent years.
Simon Culkin, Managing Director at Grain LNG, noted that the EOI is intended to help the terminal better understand market requirements. The goal, he indicated, is to ensure that the proposed capacity offering and its supporting arrangements are aligned with what the market actually needs.
Responses received by July 15, 2026, will directly inform the development of the final product offering. The shape of what eventually comes to market will reflect the feedback gathered through this process. That said, the EOI doesn’t automatically lead to a formal capacity allocation—any decision to proceed to that stage and the timeline for doing so will be communicated separately.
The Final Offer Will Be Shaped by the EOI
Grain LNG has opened an Expression of Interest for approximately 200,000 m³ of LNG storage and 125 GWh/day of regasification capacity, available from October 2029 as existing contracts expire. The EOI is non-binding and open to all market participants until July 15, 2026.
The terminal is exploring full awards, split capacity with a sharing arrangement, and joint bid structures. Market feedback gathered through the EOI will shape the final offering.
Any formal capacity allocation process will be announced separately, with its timeline confirmed by Grain LNG at a later stage.
