Energy / Two years of underground cabling works proposed by SSEN
A TWO year programme of underground power cabling works, which would stretch almost 27 miles through Shetland, could begin next year.
SSEN Distribution is proposing to install two high voltage distribution cables between the Gremista Grid Supply Point in Lerwick and the North Mainland. An image of the proposed route can be found through a link here.
A major part of the plans – called the North Shetland Reinforcement Project – would see Sullom Voe Terminal (SVT) connected to the network via the cables as part of decarbonisation plans for the site.
Currently the terminal has its own gas-fired power station, but this is due to be decommissioned.
SSEN will hold two public consultation events about the North Mainland project later this month – one in the Brae Hotel on 22 October, and the other in Lerwick Town Hall the following day.
The cable route would stretch 43km through the isles, and would cross through both private land and public roads – likely resulting in disruption to drivers.
The energy giant said it would take “around two years” to install the full network.
“The advanced cabling works portion of the project, which is 12km in length, is expected to last approximately nine months and will involve teams carrying out a rolling programme of works in sections of approximately 500m at a time,” it said.
“Full details of the cable route and the work schedule will be posted once dates are finalised with landowners and Shetland Islands Council.”
In addition, SSEN will build a new switching station at Quoys of Garth in the North Mainland.
Also involved are upgrades to substations at Firth and Mid Yell as well as “minor reconfigurations of existing overhead lines”.
It said this “essential upgrade” was at the development stage, and would increase capacity for future projects related to low carbon or decarbonisation.
The Scatsta Airport site near SVT is also earmarked for possible hydrogen production, while two wind farms are planned by Statkraft in Yell.
SSEN added it would also “improve the reliability and security of the power supply for communities across the islands”.
The company said more detailed plans are expected to be announced in spring 2025, following this month’s public consultations.
