Scottish and Southern Electricity Networks (SSEN) Transmission has resubmitted the investment case for its proposed Shetland transmission link to regulator Ofgem.
The ‘needs case’ has been updated with new economic analysis, according to SSEN Transmission.
The grid operator is seeking regulatory approval for a 600MW transmission link, conditional on the main driver for the link, the 457MW Viking wind farm, reaching a positive final investment decision.
By connecting Kergord on the Shetland Isles to Noss Head on the Scottish mainland, the transmission link enables integration of increased levels of renewable generation on Shetland for export to the Scottish mainland.
The link is scheduled to be energised and operational by April 2024.
Commenting on the ‘needs case’, SSEN Transmission managing director Rob McDonald said: “We have submitted a robust investment case to Ofgem which makes it clear that a 600MW link remains the most economic, efficient and timely option to secure Shetland’s future energy needs.
“As well as providing a connection for Shetland’s renewables, the link will also help address Shetland’s security of supply needs as well as offering Shetland’s oil and gas sector a unique opportunity to decarbonise its operational electricity requirements, delivering a whole system approach to support the transition to net zero emissions.
“Whilst we have listened to calls to consider delaying investment to develop a bigger link, our analysis shows that a bigger link would not be economic or efficient and would create a delay of at least two years, jeopardising the potential of any transmission link to Shetland proceeding.
“We now look forward to working constructively with Ofgem, our contracted developers and other stakeholders to progress the transmission link in a timely manner.”
