The array will be situated between the Skerries islands and Carmel Head off the Anglesey coast.
The tidal farm, which will consist of seven twin rotor turbines, will use MCT’s tidal energy technology known as SeaGen and which works in principle like an underwater windmill to generate power to supply electricity to up to 10,000 homes.
The businesses will be contracted for the assembly, installation, operation and maintenance of the£70m ($112.7m) tidal array.
Marine Current Turbines CEO and founder Martin Wright said the tidal power project is in line with the Welsh government’s energy policy and help in realization of its renewable energy targets.
"It aims to capture 10% of the tidal stream and wave energy off the Welsh coast by 2025, making Wales a UK low carbon economic area for tidal energy," Wright said.
