National Grid LNG Storage announces the start of a stakeholder consultation process to cease operational activities at its last remaining LNG Storage site from 30th April 2016. This date is based on the assumption that Avonmouth LNG storage can continue to offer and operate a liquefaction service during the 2015/16 season. This proposal does not affect the provision of services from National Grid’s Grain LNG Importation Terminal on the Isle of Grain.
The consultation will run between 27 November 2014 and16 January 2015. Following this a formal announcement will be made to stakeholders by March 2015.
Avonmouth is the last
remaining of 5 LNG Storage facilities built in the 1970s and 1980s to provide
Transmission support at the extremities of National Grid’s high pressure
pipeline network. The LNG storage sites liquefied pipeline gas during the
summer, stored the liquid at -160oC, then regasified it to provide rapid but short-duration
support on the few days of demand each year. However, as
the topography of pipeline networks and gas supplies into the UK have
materially developed over the decades, the Isle of Grain facility was converted
to a LNG importation terminal in 2005 and the other LNG Storage sites have
closed. The Avonmouth LNG Storage facility
primarily provides services for customers wishing to reload LNG onto road
The Avonmouth facility is characterised by assets approaching
the end of their technical life (30+ years). Although safe, and in spite of significant inspection, maintenance and
strategic spares provisions, the site has experienced a number of failures of its process plant in recent
years. Accordingly LNGS have engaged with stakeholders and customers in recent years
highlighting the resilience risks and the need for its customers to implement
In light of the above, and as a prudent operator, NG propose to cease operational activities at Avonmouth on 30
April 2016 thereby minimising any future disruption through unplanned failure. We would welcome stakeholders feedback on this proposal and ask you to submit comments either directly to David.email@example.com or via the feedback form opposite.
