Ofgem Endorses Ambitious £2 Billion Initiative for North Sea Wind Power Cable Connection

Updated: Mar 28





The Eastern Green Link 1 initiative significantly strides towards enhancing renewable energy transmission across the UK. Ofgem's recent announcement of a provisional £2bn funding package underscores the commitment to propel this ambitious project forward.


At its core, the Eastern Green Link 1 (EGL1) scheme envisages the installation of a 200-kilometre high-voltage subsea cable, poised to ferry 2GW of clean electricity from East Lothian to County Durham. This endeavor bolsters domestic energy security and aligns with the nation's fervent pursuit of net zero targets.


Although the project's potential impact is contingent upon securing planning consent, it looms large. With aspirations for operationalization before the decade draws close, EGL1 embodies hope for expedited energy infrastructure development.


Ofgem's Accelerated Strategic Transmission Investment (ASTI) framework underpins this initiative and is poised to expedite crucial electricity infrastructure projects. By fast-tracking funding processes by up to two years, ASTI aims to alleviate the bureaucratic hurdles that impede progress in the sector.


"To meet future energy demand and government net zero targets, we need to accelerate the pace at which we build the high voltage energy network, which transports homegrown electricity to where it's needed," said Ofgem's director of major projects, Rebecca Barnett. "Eastern Link 1 is the first project to reach this stage under our new fast track ASTI process designed to unlock investment, speed up major power projects, and boost Britain's energy security." 


EGL1's significance extends beyond regional boundaries, dovetailing with the UK's ambitious offshore wind targets. As the nation sets its sights on achieving 50GW of offshore wind capacity by 2030, EGL1 emerges as a linchpin in facilitating the transmission of wind power generated in Scottish waters.


Moreover, the project promises manifold benefits for consumers. By harnessing homegrown wind energy, EGL1 ensures a sustainable energy supply and mitigates compensation costs associated with grid constraints during peak wind output.


As outlined in its recent blueprint, EGL1 aligns with National Grid's broader vision for a fully decarbonized power grid by 2035. The project's strategic placement, with most of the cable under the North Sea, underscores its seamless integration into existing infrastructure.


Collaboratively developed by National Grid Electricity Transmission and SP Transmission, EGL1 exemplifies meticulous planning and fiscal responsibility. Ofgem's rigorous scrutiny of the project budget reflects a commitment to maximizing consumer benefit while minimizing undue financial burden.


"We've streamlined the approval process without neglecting our due diligence," Barnett said. "We've carried out rigorous checks to ensure consumers are shielded from unnecessary costs and made cost adjustments where we don't see maximum efficiency and consumer benefit."


EGL1 paves the way for a greener, more resilient energy future, standing as a testament to collaborative efforts and steadfast commitment to realizing the UK's renewable energy ambitions.
