Sustainable Marine Grand Passage

In September 2018, Sustainable Marine Energy (SME) began the installation of a 280 kW floating tidal platform (PLAT-I 4.63), equipped with four SCHOTEL Hydro SIT250 tidal turbines (70 kW each). The system was fully commissioned and operational by February 2019.
A next-generation 420 kW platform (PLAT-I 6.4), equipped with 6 tidal turbines, was built in 2021 and installed at Grand Passage, delivering power to the grid as of April 2022. This was the first tidal project to generate power delivered to the Nova Scotia grid. The PLAT-I 6.40 was designed specifically for operation at the FORCE Test Site site, where SME had plans to relocate the prototype, as part of eventually establishing a tidal farm in the Minas Passage consisting of three of SME's platforms. However, SME entered voluntary bankruptcy in 2023 citing permitting issues, placing its PLAT-I platforms into storage and removing all equipment from the seabed at the site.
