First Power

The Western HVDC Link (Western Link), a joint project delivered by SP Transmission (SP Energy Networks) and National Grid Electricity Transmission, was energised and entered service on 7 December 2017 at reduced capacity. Initial operation began with an approximate 900 MW capability while final commissioning works continued at the Hunterston converter site. The energisation brought the subsea HVDC connection between Hunterston (Scotland) and Flintshire Bridge/Connah’s Quay (Wales) into service so that power could begin to flow bi-directionally across the link to support north–south transfers of low‑carbon electricity.
