Currently, the facility has a storage capacity corresponding to 10% of Denmark’s annual gas consumption. The Lille Torup natural gas storage facility consists of a total of seven caverns situated in a salt dome at a depth of 1,200m to 1,700m. The caverns are 200m to 300m high, and 50m to 65m in diameter.
The expansion of the storage facility is conditional to the approval by authorities. An environmental impact assessment procedure has been initiated in order to analyze the impact of expanding the storage facility with nine new caverns, re-leaching the existing seven caverns and doubling the size of the existing process facilities.
The environmental impact assessment report is expected to pave the way for a subsequent decision to gradually expand the storage facility as the need for storage capacity grows.
The first step in the expansion is a DKK119 million investment in the refurbishment of an existing leaching plant and the re-leaching of one of the seven existing caverns. Leaching will take place over a period of three years and will increase cavern volume by 15% annually.
