The final two caverns at Eon’s 160million cubic metre gas facility entered operation earlier this month, completing the final stage of development at the site.
Jo Vizor, manager director, Eon Gas Storage UK said: “This is a real landmark day for E.ON’s UK gas storage business.
“The team has done a fantastic job in creating and delivering a modern fast churn storage facility that makes a real contribution to balancing the UK daily gas market.”
Construction work on the project began in 2006 with the installation of the brine and water infrastructure and the first three caverns became operational in December 2011.
