    LNG Storage

    National Grid LNG Storage (a trading division of National Grid Gas (NGG)) provides storage services from a single facility located at Avonmouth (near Bristol).

    The facility liquefies natural gas by cooling it to -160 degrees centigrade and stores it in liquid form. The key feature of the facility is its location and its ability to rapidly revaporise the natural gas, and deliver it to the National Transmission System (NTS). As a result, LNG storage is able to provide a peak gas supply to shippers and supplement NGG's network capacity. In addition, LNG Storage is used as a contingency against the risk of emergencies such as system constraints, failures in supply or failures in end user interruption.

    When an annual service is booked, a quantity of injectability, space and deliverability is reserved for a whole year. The cost of this capacity is invoiced in 12 monthly instalments. In addition to capacity charges, the customer pays commodity charges on the quantities of gas injected in to storage or withdrawn from storage.


    National Grid LNG Storage invites you to take part in a stakeholder consultation process regarding the closure of operational activities at its last remaining LNG site from 30 April 2016.

    For the 2014/15 Storage Year National Grid does not require a minimum inventory to be maintained at the Avonmouth facility

    Tanker Filling Service


    For 2014/15 a Tanker Filling Service is being offered by LNG Storage at its Avonmouth facility. The tanker filling service is available to transporters and other customers. In the past, other customers have used tanker loads of LNG for purposes including vehicle fuel supply, gas research, fire-fighting practice and the testing of gas turbines.

    Customers may book tanker-filling slots for a year according to the maximum number of tankers that they will need to fill in one day. The commodity charge for injecting gas into the space is the same as the standard injection commodity charge for the facility. For withdrawals there is a standard charge per tanker filled or partially filled which is set out in the Annual Storage Invitation.

    In order to utilise the Tanker Filling Service customers must have access to LNG in store.
