SCD1, the proposed 2GW offshore HVDC link between Suffolk and Kent is planned to transfer renewable energy generated from offshore wind farms on the coast of East Anglia to demand within the south east of England, bypassing the most constrained areas of the network. National Grid Electricity System Operator’s Network Options Assessment (NOA) 2020/21 indicates a cost band for this project of £1 billion - £1.5 billion. The NOA 2020/21 analysis suggests SCD1 could provide significant economic benefit to multiple areas in the south and east regions as it can be configured to transfer power in both directions.
