What is the Saltfleetby Gas Field?

The Saltfleetby Gas Field is a naturally occurring reservoir of gas almost a mile and a half below the surface of land between Saltfleetby and South Somercotes and to the west of Skidbrooke. It is made of porous rock which allows gas to flow through it and is topped by many layers of solid rock that seal in the gas.

It has held gas naturally for millions of years and since 1999, gas has been taken out of it to provide fuel for homes and businesses. This is done by drilling well bores down into the reservoir and letting the gas come to the surface under its own pressure. The gas is then fed through a pipeline to Theddlethorpe and into the UK’s national gas grid.

What is happening now?

Today, the natural gas at Saltfleetby is beginning to run out and WINGAS Storage UK is now proposing to change the use of the reservoir from production to storage — in short, the reservoir will be topped back up with natural gas which can be used at times of high demand for energy, usually in winter.

The change of use requires the installation of a new plant near the current well sites, the drilling of new wells and the laying of new pipelines to supplement the ones that already feed the gas produced at Saltfleetby into Britain’s gas supply.

A full environmental impact assessment of the development was undertaken and accompanied WINGAS Storage UK Ltd’s application to DECC for a Storage Authorisation Order. Lincolnshire County Council and East Lindsey District Council will be closely involved in this application and be in receipt of all details regarding the project.

Who is being consulted?

WINGAS Storage UK is consulting a number of groups, local residents, District and Parish Councils, Lincolnshire County Council, the Health & Safety Executive, the Environment Agency and others set out in the full application.

The applicant seeks consent to operate a gas storage facility and this includes an application for a Storage Authorisation Order, Deemed Planning Consent and a Hazardous Substance Consent.
