Member News: Marine surveys continue for the UK’s biggest ever electricity transmission project 

A series of important marine surveys will be taking place over the coming months in Sandford Bay near Boddam, Peterhead, as part of the Eastern Green Link 2 (EGL2) project – the UK’s biggest ever electricity transmission project.

EGL2, a joint venture between SSEN Transmission and National Grid Electricity Transmission, will see the installation of a 505km 2GW high-voltage direct current (HVDC) subsea cable linking Peterhead in Scotland to Drax in Yorkshire. The electricity superhighway will transport enough clean energy to power around two million homes.

To inform the cable’s route and design, the following marine survey activities will be carried out:

  • Geophysical Surveys (May-June 2025):
    Vessels will conduct daily sweeps of Sandford Bay to collect seabed and subsurface data;
  • Geotechnical Surveys (July-August 2025):
    A jack-up barge will collect seabed core samples at four offshore positions; and
  • Unexploded Ordnance (UXO) Investigations (August-October 2025):
    Remote operated vehicles will scan an 80-metre-wide seabed corridor along the cable route to detect and safely assess potential UXO targets.

In addition to the offshore work, onshore environmental and technical surveys will be carried out near Sandford Bay, starting this month.

Ricky Saez, EGL2 Project Director, said:
“These surveys are an essential part of planning and delivering a project that will help unlock the full potential of Scotland and the UK’s renewable energy resources.

“We’re grateful for the cooperation of local residents and the fishing community as we work to deliver this nationally important infrastructure.”

Public access to the beach will remain unaffected throughout the operations and notices to mariners will be issued ahead of each survey phase – with the project team committed to ongoing collaboration with the local fishing community.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.

Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.

Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
