We would like to thank road users and local communities for their patience and understanding while this essential programme of work is carried out.

The existing cable powering this part of the network is reaching the end of its operational life, this essential upgrade is required to ensure resilience of supply for Peterhead. The new infrastructure will continue to ensure homes and businesses in the area have a reliable electricity supply.
What is involved in the cable replacement project?
Replacement of existing cable: Around 16km of existing underground electricity cable between Peterhead Power Station and St Fergus Gas Terminal will be decommissioned and replaced with new cable.
Installation of new underground infrastructure: New underground cable will be installed mostly along the existing route, primarily within the A90 corridor and adjacent verges and footpaths.
Rolling traffic management: A programme of rolling traffic management will be implemented along the A90 to minimise disruption and allow our teams to work safely. This will take place in short sections of approximately 600 metres at a time to limit disruption for road users and local communities.
Working with key partners: We are working with trunk roads operator AMEY and Aberdeenshire Council to coordinate activities and ensure any disruption is minimised throughout the project.
Why is this essential upgrade needed?
End of operational life: The existing underground cable has reached the end of its operational life and requires replacement to maintain a safe and reliable power supply for all local homes and business.
Improved network resilience: Upgrading the cable will ensure the local electricity network is robust and can support all energy needs for the area, reducing the risk of faults and unplanned outages.
Future readiness: Renewing this key section of infrastructure supports the development of the network and future energy needs, such as EV Chargers and electric heat pumps for residential homes and business.
What impact will this have on local communities and road users?
Traffic management on the A90: Temporary traffic management measures, such as single lane closures and speed restrictions, will be required along sections of the A90 and adjacent verges and footpaths while works are underway.
Rolling, short-duration works: We will typically work on short sections of the route around 600 metres, reducing the length of any one section affected at a time, and ensuring we keep traffic moving.
Access maintained where possible: Maintaining access to properties, businesses and local facilities wherever it is safe to do so is a priority for our team, and any unavoidable restrictions will be communicated in advance.
Ongoing communication: Road users, residents and businesses will be kept informed through signage, online updates, local media and, where appropriate, direct engagement.
Site reinstatement: On completion of works in each section, the working area will be reinstated as close as reasonably practicable to its original condition.
Project timeline and next steps
Project duration: This £12m+ project will be ongoing until Autumn 2027.
Current phase: Cable replacement works are being delivered in a series of rolling sections along the A90 between Peterhead Power Station and St Fergus Gas Terminal.
Traffic management programme: Traffic management will move progressively along the route as each 600‑metre section is completed and the next section begins.
Ongoing coordination: We will continue to work closely with AMEY and Aberdeenshire Council to plan and manage works, aiming to minimise disruption wherever possible.
Completion: Once all sections are complete and the new cable is fully commissioned, the project will provide a long‑term, resilient electricity supply route for the area.
