Ofgem are expected to publish a decision on the Final Needs Case for the Western Isles in Autumn 2019.
In March this year, Ofgem announced that they were minded to reject the proposal by SSEN to build a 600MW transmission link to the Western Isles.
The company favoured a 450MW link and subsequently launched a consultation seeking the views of stakeholders and the public.
Commenting Angus MacNeil MP said: “When Ofgem announced in March that they were minded to favour a 450MW transmission link instead of a 600MW link, I appealed to Ofgem to think again and do what is best for the environment and the economy.
“Approval of a 600MW link is crucial for development in our islands, which have the strongest wind resource in Europe.
“The UK Government have set an ambitious target to reduce greenhouse gas emissions to almost zero by 2050, constructing an adequate link to the Hebrides will help that aim. I have repeatedly raised this matter with Ofgem and the UK Government and I hope Ofgem will listen and make the right decision this Autumn.”
