About Grain LNG

Grain LNG is Europe’s largest LNG regasification terminal and is located at Isle of Grain, to the east of London. The core service is the provision of LNG storage and regasification capacity to primarily strong investment-grade customers under long-term, inflation-linked capacity contracts. The terminal has annual regasification capacity of 21.7 bcm and tank storage capacity of 1,000,000 cubic metres.

Grain is currently undergoing an expansion of 5.3 bcm additional regasification capacity and an additional 200,000 cubic metres of storage capacity. After completion of the ongoing expansion of the site, it will be able to provide up to a third of the UK’s gas demand. Grain also offers additional services such as ship reloading, transshipment and road tanker loading.

Long-Term Contract Portfolio

Grain is 100 percent contracted until 2029, more than 70 percent contracted until 2038 and more than 50 percent contracted to 2045. It is envisaged that future capacity auctions will be held on an arm’s length basis in accordance with current regulated third-party access requirements. Grain’s strategic location east of London offers efficient loading and storage capabilities and advantaged access to UK markets.
