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.

Isle of Grain LNG Terminal Vessel Approval Expiry Dates

• Grain LNG Shippers are required to release berthing slots they are not intending to use, and Grain LNG may further from time to time identify unused capacity sufficient to offer additional berthing slots. These slots will be advertised on this Bulletin Board and Registered Users are invited to submit bids in accordance with the auction process outlined in the Third Party Access Guide.

Bids should be submitted by completing a Short Term Access Confirmation Notice which is contained in Schedule 6 of the Short Term Access Framework Agreement (available to Registered Users). Completed forms should be emailed to box.glngcommercial@grainlng.com. Upon completion of an auction, Grain LNG will select the winning bid, notify the successful party and sign the relevant Confirmation Notice, thereby completing the execution process.

Please note that while the following berthing slots are available for potential customers to enquire about, Grain LNG will need to consider storage availability before accepting any bid and will assess each bid on a case by case basis.

Please see below the currently available slots:

• 14th September 2026

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:

• receiving LNG ships up to the size of QMax vessels and unloading them
• temporarily storing LNG in cryogenic tanks with a site capacity of approximately 1,000,000 m3
• re-gasifying and processing LNG (including blending and ballasting where necessary to meet network entry requirements)
• delivering gas into the national transmission and local distribution systems in accordance with customer nominations
• ship cool down
• ship reloading
• truck loading
• truck cool down

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.

Transmission System Operator (TSO) information

Each capacity holder is required to make its own arrangements with the TSO for entry capacity onto the National Transmission System.

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.

• 3.3 million tonnes per annum (mtpa), of capacity has been contracted under Phase 1 on a long term basis from July 2005
• 6.5 mtpa of capacity has been contracted under Phase 2 on a long term basis from December 2008
• 5 mtpa of capacity has been contracted under Phase 3 on a long term basis from December 2010

Together these equate to circa 654 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:

• General Terms and Conditions (GTCs): These are the current general terms and conditions on which GLNG provides the services at the Terminal.
• Specific Terms Agreement (STA). This sets out the specific and any special provisions applicable to a particular Shipper(s). Together with the GTCs, the STA will form the Service Agreement between GLNG and the Shipper(s).
• Terminal Operating Procedures (TOPs): The TOPs set out more detailed operating procedures applicable to the Terminal.
• Network Entry Provisions (NEPs): The NTS Network Entry Provisions set out the operating interfaces between the Terminal and NGG’s National Transmission System (NTS).
