Under the 20-year agreement, Meridian LNG will deliver the gas to E.ON through its planned Port Meridian import and regasification terminal.

E.ON has an option to increase its purchases to a maximum of 750 million standard cubic feet a day.

EGC CEO Christopher Delbrück said: "It builds on our already diverse supply portfolio and provides further momentum for the business. As gas markets in North America, Europe and Asia become increasingly interconnected, LNG is becoming a critical enabler for the optimization of E.ON’s asset base."

Meridian LNG, through a joint development agreement with Höegh LNG, will ship LNG to Port Meridian using a combination of traditional LNG carriers as well as the FSRU.

Meridian LNG president and CEO Roger Whelan said: "The offtake agreement is a critical requirement for the launch of our Port Meridian UK regasification terminal, which when combined with our Joint Development Agreement with shipping and regasification partner Höegh LNG, and the anticipated supply from Magnolia LNG, completes a unique, low-cost and flexible LNG supply chain into Europe."

A 20-year, 2mtpa liquefaction term sheet was signed earlier between Meridian LNG and Magnolia LNG, the owners of the proposed Magnolia LNG facility in Lake Charles, Louisiana, US. The companies are planning to sign a tolling agreement soon for Magnolia to provide LNG to Meridian from early 2019.
