Thank you for your interest in the send-out data from the Grain LNG terminal on the Isle of Grain in Kent. Please use the links below to access the data you need:
Instantaneous Flow Data : please select the 'Instantaneous Flows into NTS' gas market data tools
Stock Level Data : please scroll down to 'Supplementary Reports' sections and select the latest report under 'Daily Storage and LNG Operator Information'. Please note this will open in an excel spreadsheet.
Please note that following the commissioning of the new National Grid Gas receiving facilities at the facility, the terminal can now flow gas into the National Transmission System (NTS) via two pipeline feeders, this is in addition to its existing connection into the Local Distribution Zone operated by Scotia Gas Network.
The information provided on the National Grid Gas website provides instantaneous flows from each of the two NTS feeders (Isle of Grain NTS1 and Isle of Grain NTS2) as well as a total figure which is the sum of the two NTS feeders plus the flow of gas into the LDZ (entitled Isle of Grain Terminal in the table entitled Terminal Totals).
It is also important to note that following the successful commissioning of the expansion phase at Grain LNG the plant now operates as one terminal and as such gas flows in specific feeders are not attributable to specific customers. The terminal has the flexibility to flow any customer's gas to any feeder at any given time.”
If you have any questions with regard to this send out data please contact Commercial operations on 01926 656556.
Before an LNG tanker can berth and unload at the terminal, the LNG tanker must be approved (vetted) by Grain LNG for the purposes of satisfying Grain LNG as to the competence of the Tanker Operator, Master, officers and crew, and the compliance of the LNG tanker and the Tanker Operator with the standards required by Grain LNG for the safe, efficient and reliable operation of the Terminal and of LNG tankers at the Terminal.
For capacity holders (whether primary or secondary) with a current Services Agreement in place with Grain LNG, LNG tankers can be vetted and approved in accordance with the provisions of that Services Agreement, and such capacity holders should continue to apply for approval of LNG tankers in the normal way under their current Services Agreement. When the ship's approval period expires, they will require re-approval but will not normally be required to go through the full vetting process.
Grain LNG recognises that other parties may be interested in using the terminal in the future, possibly at short notice (e.g. through “use-it-or-lose-it” (UIOLI) arrangements or as a secondary capacity holder), and may wish to have one or more LNG tankers vetted prior to entering into a Services Agreement with Grain LNG. To this end, the Grain LNG Ship Vetting and Approval policy (available for download below) as defined in Annex M of the Terminal Operating Procedures (TOPS) was developed to cover all the requirements for ship vetting in Grain LNG. A list of all ships currently vetted by Grain is also available for download below. This list includes ships that have been vetted but their validation dates have expired.
It should be noted that approval of an LNG tanker to use the berth can be withdrawn by Grain LNG at any time. The party who requested the vetting of the LNG tanker will be notified of the withdrawal of approval and the reasons for such withdrawal of approval.
Applicants must first contact Grain LNG’s Commercial department to request a ship vetting (see Contacts page for details). Grain LNG will then provide compatibility templates and mooring information for the berths at Grain LNG.
To obtain an estimate of the costs of vetting an LNG tanker, please contact Grain LNG’s Commercial department (see Contacts page for details). As an indicative figure only, our inspectors are charged out at approximately £600 per day plus expenses, and (again, as an indication only) total inspection costs can range from £2,200 to £4,000 depending upon the location of the LNG tanker.
Applicants are charged the actual costs incurred by Grain LNG in inspecting and vetting the relevant LNG tanker. Grain LNG will advise the applicant of the actual costs incurred and will send an invoice to cover.

Two LNG unloading jetties, one capable of unloading LNG tankers of 70,000 m3 to 217,000 m3 cargo capacity (QFlex) and the other capable of unloading LNG tankers from 125,000 m3 up to 266,000 m3 cargo capacity (QMax).
Total storage capacity ~1,000,000m3.
Submerged Combustion Vaporisers (SCVs) capable of regasifying 645 GWh/d (58 mcm/d or 2.1 bcf/d).
Propane Storage and Injection Facility
Two Liquid Nitrogen Plants (owned and operated by Air Products) with a total of four Air Separation Units and storage capacity for 5000 tonnes of liquid nitrogen.
2 loading bays
36 slots a day
Maximum loading of 80m3/h
The Grain LNG terminal provides services consisting of:
Unless otherwise agreed, LNG that is unloaded at the Grain LNG terminal must comply with the gas entry specifications outlined in the General Terms and Conditions (GTCs), which can be obtained by completing the Confidentiality Agreement.
Grain LNG has the capability to blend various LNG specifications to comply with the UK gas entry specification. Please contact Grain LNG if your cargo is not within the specifications outlined in the GTCs.
Each capacity holder is required to make its own arrangements with the TSO for entry capacity onto the National Transmission System.
For information on network entry arrangements, please visit the National Grid Website.
Grain LNG is also connected to the Distribution Network operated by Southern Gas Networks. Applicants and capacity holders do not need to contact SGN in order to utilise capacity at Grain LNG terminal.
All primary capacity at the terminal has been sold through open season processes and is fully contracted.
Together these equate to ca. 645 GWh/d regasification capacity, 1,000,000m3 of LNG storage capacity and over 200 berthing slots per annum.
The regulatory arrangements for Grain shippers requires the primary capacity holders to facilitate secondary trading (berthing slots, storage and regas capacity) to Secondary Shippers.
For enquiries as to the availability of secondary capacity from the current primary capacity holders, please contact the primary capacity holders.
To the extent that primary capacity (or secondary capacity) is not being utilised, in accordance with the terminal’s exemption from Third Party Access requirements Grain LNG operates a ‘Use It Or Lose It’ (UIOLI) process at the terminal. Available quantities of UIOLI capacity are available via the secondary capacity page.
The legal documents applicable to use of the Terminal are:
The following documents will be applicable from July 2025 for new Shippers:
In compliance with Regulation EC 715/2009, information about the stock level, aggregate flows and the available capacity at the Terminal is reported daily by National Grid and is available on our Storage Information page on the National Grid website.
