Wedoany.com Report-Dec.7, The MeyGen Tidal Array in Scotland's Pentland Firth, recognised as the world's largest operational tidal stream energy project, has scheduled subsea operations from 10 to 17 December 2025. Activities will include turbine recovery, subsea cable maintenance, and equipment deployment in the Inner Sound between the Scottish mainland and the island of Stroma.
Solstad Offshore's construction vessel Normand Vision will support the work.
Owned by SAE Renewables, MeyGen secured a lease agreement from The Crown Estate in October 2010 for up to 398 MW of tidal stream capacity to be developed in phases. Phase 1, a 6 MW demonstration array comprising four 1.5 MW three-bladed horizontal-axis turbines on gravity-base foundations, became fully operational with the deployment of its final turbine in December 2024. The array entered its 25-year operational phase in April 2018 and has delivered continuous power output, recently achieving over six years of uninterrupted performance using SKF technology.
A subsea hub installed under Project Stroma in September 2020 enables multiple turbines to connect to a single export cable.
Phase 2 has secured consent for 59 MW, with commissioning targeted for 2027, 2028, and 2029. Following the achievement of a key contractual milestone in July 2022 for an additional 28 MW, SAE deployed a tidal flow measurement device at the site in October 2022.
SAE is also exploring the integration of energy storage solutions at the location, building on experience from its Uskmouth Energy Park, under the concept of the MeyGen Sustainable Energy Park.
The upcoming December operations mark continued development and maintenance of this flagship tidal energy site, reinforcing its role as a leading global example of large-scale tidal stream generation.
