General – Preferred Bidder
National Grid Electricity Transmission and SP Energy Networks have selected Siemens Energy as the preferred bidder for the Eastern Green Link 4 (EGL4) project’s two high-voltage direct current (HVDC) converter stations.

EGL4 is a proposed new 2GW high voltage direct current (HVDC) electricity link which will transport clean, home-grown energy between Fife, Scotland, and West Norfolk, England, and onto the network via a 530km high voltage subsea cable – helping to boost capacity and energy security.
Siemens Energy was also recently awarded a place on National Grid’s £59bn HVDC supply chain framework and SP Energy Networks £5.4bn Strategic Agreement to deliver the required works and equipment needed for key energy projects across the country.
Much of the UK’s new offshore and onshore wind generation is in or around Scotland, but the existing transmission network does not have the capacity to move all this cleaner electricity to where it is most needed.
New long-distance, bi-directional, subsea infrastructure like EGL4 is essential in strengthening Britain’s energy security with home-grown energy and keeping bills more affordable by reducing reliance on expensive imported fossil fuels.
EGL4 is one of five proposed subsea links between Scotland and England being delivered through joint ventures with Scottish transmission owners. Together, the five links will be capable of powering up to 10 million homes.
