GEC

GEC designed, manufactured and built the Sellindge HVDC converter station on the UK side of the 2,000 MW, ±270 kV IFA1 (IFA 2000) interconnector between Great Britain and France. The Sellindge station, commissioned in stages between 1985 and 1986, forms one of the two main converter terminals of the link and includes thyristor valve halls, converter transformers, smoothing reactors and associated reactive power filters. GEC’s scope covered delivery and construction of the complete converter installation at Sellindge to enable high‑capacity HVDC power exchange between the British and French transmission systems.
