The village centre is eight miles (12 km) south-east of the town of Ashford. This station is at the British end of the interconnecter which joins the national electricity grids of Great Britain and France via high-voltage DC submarine cable, allowing power to be transferred between the two countries according to supply and demand and converted to the appropriate AC standards for onward transmission. This latest project aims to support the extension of the operational life of the converter station through a refurbishment programme, with a focus on ensuring interoperability of legacy and the latest control systems. The landing point for the subsea cable linking France to the UK is Folkestone, from where underground cables connect to the Sellindge converter station and then onto the UK's transmission station. Under the terms of a contract with British grid operator National Grid (LON:NG), Siemens will deliver, install and commission four 400-kV and 315 MVA transformers for the Sellindge converter station in England.
