Atlantis Resources has connected its flagship tidal project MeyGen to the Scottish grid.
MeyGen has a capacity of 400MW and is expected to generate enough electricity to power 175,000 homes.
The marine energy company has connected the tidal project to a 33kV distribution network through underground power export cables.
Tim Cornelius, CEO of Atlantis said: “We believe this is now the world’s largest energised grid connection of any commercial tidal stream array. We have made great progress over recent months at MeyGen on turbine and foundation preparation and we very much look forward to delivering first power to the grid later this year, which will be a huge event for our company and the global marine power industry.”
The site is expected start generating power from the second half of 2016.
According to new research, the global wave and tidal energy market is forecast to be worth $11.3 billion (£8bn) by 2024.
