The whole site consists of four plants: two run by Perenco, one by Centrica and one by Gassco.

[3] This was the first time that North Sea Gas had been brought ashore in the UK from the West Sole field.

[10] The sites are run by and gas is produced by Perenco (after BP sold its operations to them in 2012),[11] Gassco and Centrica Storage Ltd. Gas can be transferred to and from the Centrica Storage plant at Easington dependent on grid demand.

The function that is at the Perenco Easington site is the connection to the National Transmission System.

Gas flows from the Easington terminal via a 24-inch diameter, 90-mile (140 km) pipeline known as Feeder No 1 across the Humber to Totley near Sheffield.

[13] As part of the facility, two RB211-GT61 gas turbines, built by Rolls-Royce Energy Systems in Mount Vernon, Ohio, were installed in a £12.7 million contract.

[14] The Rough Terminal also processes gas for the newly developed York field.

[15] The Rough Terminal used to receive gas from the Amethyst gasfield which was until 1988 owned by Britoil but this is now processed by Perenco.

Since 2013 The Rough Terminal has also processed gas from the York field on behalf of Centrica Energy.

The Langeled pipeline, which is controlled at the UK end by Gassco (Centrica Storage Ltd before 2011), can transfer up to 2,500 m cubic feet of gas per day from Nyhamna in Norway.

Dimlington also processes dry gas from the (former) Cleeton, Ravenspurn South, Ravenspurn North, Johnston, the Easington Catchment Area (Neptune and Mercury), and the Juno development (Whittle, Wollaston, Minerva and Apollo) gas fields.

[clarification needed] Cleeton and Ravenspurn South form part of the Villages Complex.

Discovered in April 1983, 43 miles (70 km) off the East Riding of Yorkshire coast.

First gas produced in October 1989, and BP took over the operatorship of the field from BHP on 12 January 1998.

Owned 40% by Dana Petroleum (E&P) Ltd, 47% by E.ON Ruhrgas UK EU Ltd and 13% by Centrica Resources Ltd. Named after the mathematician, Charles Babbage.

These fields are connected to the national grid by BP and Rough Terminals.

Some of these were one of the 'Villages' gas fields; named after villages lost to the sea along the Holderness coast.

These villages include: Cleeton, Dimlington, Hoton, Hyde, Newsham and Ravenspurn.

It is a faulted dome whose maximum dimensions are about 12 by 3 miles (19.3 by 4.8 km) wide, lying at a depth of 9,000 feet (2,700 m).

The reservoir comprises about 400 feet (120 m) of Permian Rotliegendes sandstone, and the gas has a high methane content and low nitrogen (1.3%).

BP took control in January 1997, in exchange for its Jupiter gas field.

Named after Hoton, one of the East Riding of Yorkshire lost villages that fell into the sea due to coastal erosion.

Originally owned by BG Storage Ltd (BGSL), who were bought by Dynegy Europe Ltd in November 2001 for £421 million.

To operate the field Centrica has to comply with a set of undertakings laid down by DECC and Ofgem due to its unique position in the UK gas market.

Owned and operated by Centrica with the gas pumped back to Easington via the Amethyst field.
