injected into the wells to dissolve the salt and create brine which was supplied to local industry for the production of bulk chemicals, such as soda ash and chlorine. The caverns created are about 300' (90 metres) in diameter and 260' (80 metres) tall (each has a volume of 339,300 m; 443,800 cu. yd.) and are used to hold compressed gas. Stublach is the largest gas storage facility in the UK, containing up to 450 million cubic metres (590 million cubic yards) of gas.

The releasable volume of gas is about half of the gross volume. During periods of low demand, gas is compressed into the cavities by electrically driven compressors and fed back onto the NTS at times of peak demand.

they carried gas from southern
England into Scotland until the Frigg field began production via St Fergus in September 1977. Compressor stations are provided at 40 mile (65 km) intervals along the pipelines. A third 36-inch pipeline from St Fergus (Feeder No. 12) was completed in 1978, and a fourth 40-inch (1050 mm) pipeline (Feeder No. 13) in 1982.

The NTS was formerly supplied by the following decommissioned LNG sites: Ambergate, Derbyshire (closed 1985); Dynevor Arms, Merthyr Tydfil (closed 2009); Glenmavis, Lanarkshire (closed 2012); Partington, Greater Manchester (closed 2012); and Avonmouth, Bristol (closed April 2016).

Companies that own part of this gas network, also known as the Local

In addition to the Canvey Island liquefied natural gas (LNG) import terminal, further LNG storage sites were constructed from the late 1960s. These were peak-shaving facilities used to support the NTS at times of high demand, and to ensure security of gas supplies at strategic locations. When demand

Stublach were created by drilling 20" (50 cm) diameter holes through 1000' (300 metres) of rock and 820' (250 metres) of salt. This was followed by inserting metal tubes into the holes and filling the annulus with cement to create a leak-tight seal. Water was
