The picture below shows the new SSEN cable mid lay. The cable was laid on 20th July, slightly delayed because of poor weather.
At the time of the photograph:
The blue ship is the cabler layer and it has “thrown” a line onto Tiree.
The cable was then lain across the surface, kept afloat by the orange buoyancy aids.
After the photograph was taken:
The line was used to pull the cable on shore.
The small boats then pulled the cable over to Coll.
The buoyancy aids were disconnected.
Allowing the cable to sink to the seabed in a controlled fashion.
A Remote Operated Vehicle (ROV) then buried the cable.
Then it was connected and energised.
Finally SSE will come and tidy up.
What does it mean for Tiree?
The current cable us getting towards then end of its life. The new cable will allow a reliable connection to Coll and onto the mainland to continue. The old cable will still be connected and could be used as a backup.
It will bring increased capacity. This will help with the decarbonising of Tiree. With the increased use of ASHP, electric cars and renewable energy. (The trust solar panels, etc). Tiree’s energy profile is changing and this will allow the supply to be maintained.
SSEN have been in contact with various groups and interests on Tiree over the last 9 months, keeping us informed of progress and asking our questions. Their efforts are to be applauded.
