CMS advises NGET and SPT on electricity superhighway joint venture

CMS has advised National Grid Electricity Transmission (NGET) and SP Transmission plc (SPT) on the formation of a joint venture to deliver Eastern Green Link 4 (EGL4), for a major new subsea high voltage direct current (HVDC) electricity transmission link between Scotland and England.

The project is designed to significantly increase the capacity of the electricity network between Scotland and England, enabling the UK and Scottish Governments to meet their net-zero targets. It is one of two Eastern Green Link HVDC projects being developed in partnership between NGET and SPT, and is intended to support the transmission of up to 2 GW of clean, renewable electricity - enough to power approximately 1.5 million homes.

EGL4 will comprise a 530km subsea HVDC cable between Kinghorn, Fife and Anderby Creek, Lincolnshire; a 16km underground cable from Kinghorn to a new converter station at Westfield, near Ballingry, Fife; and a 100km underground cable from Anderby Creek to a new converter station near Walpole, Norfolk.

Nick Blair commented: “We're delighted to have advised NGET and SPT on their EGL4 joint venture - a project designed to strengthen the UK's electricity infrastructure and accelerate the transition to net zero. Our longstanding relationship with both NGET and SPT, including our previous work on Eastern Green Link 1 (EGL1), reflects our commitment to supporting clients at the forefront of the energy transition with delivering the large-scale projects necessary to secure a sustainable energy future for the UK.”

The CMS team was led by Nick Blair and Vini Cowden, with support from James Day and Alex Moore (Corporate); Emma Burnett and Joanna Willems (Data Protection); Laura Lucy (IP); Jean-Francois Willems (Regulatory); and Phil Reid and Denisa Balint (Tax). Vini Cowden continues to lead a CMS team advising on wider EGL1 and EGL4 matters.
