Project Overview
SHEPD are planning to install a replacement 11kV submarine cable across Loch Long, in the Highland Council area, as part of our commitment to maintaining the highest performance standards for Scotland’s vital submarine electricity infrastructure, serving islands and coastal communities.
The existing 11kV Loch Long submarine cable is nearing the end of its operational life. The replacement submarine cable will provide a crucial upgrade to meet the region’s ongoing energy needs and ensure the continued resilience of the local electricity network.
The project is currently in detailed design phase and is proposed to be completed by the end of 2026, with current planning targeting construction in Spring 2026.
In parallel to this submarine cable replacement, SHEPD are planning to install a second submarine cable across Loch Long. This shall be a 33kV cable and is being installed as part of a future 33kV network reinforcement project in the area, known as Nostie Bridge.
What is involved in the cable replacement project?
This project involves installing two new high-voltage submarine cables within a designated corridor across Loch Long.
The 11kV replacement Loch Long cable shall be connected to the existing network on the Dornie landing to the east, and there shall be some minor upgrades to the overhead line network on the west landing to facilitate a new submarine cable connection.
The new 33kV Nostie Bridge submarine cable shall be installed and safely stored for a future connection to the new 33kV Nostie Bridge network once constructed. The design of the 33kV Nostie Bridge network is in very preliminary stages at this time.
The existing 11kV Loch Long cable, which has reliably served the local community since 1980, will be taken out of service once the replacement cable becomes operational.
Benefits to the Community
Enhanced Reliability: the new 11kV submarine cable will strengthen the resilience of the electricity network, reducing the risk of outages and improving supply security for local communities.
Future Proof Infrastructure: by replacing ageing assets with a modern, higher-capacity cable, the project ensures the network can meet growing energy demands and support future developments.
Environmental and Safety Improvements: installation of more efficient technology will align with modern safety and sustainability standards.
Efficiency: The installation of the 33kV Nostie Bridge submarine cable as part of the same construction phase as the 11kV replacement Loch Long submarine cable, offers a cost-effective construction solution and minimises repeat disturbance for installing a second submarine cable in the same area at a future date.
What impact will this have on local communities?
We are committed to keeping local residents and stakeholders updated as we work to upgrade this crucial part of the local network and will keep all affected parties informed throughout the process with regular updates.
