In Scotland, the largest tidal power plant with a capacity of 398 MW
In Scotland, the MeyGen project is successfully implementing the deployment of hundreds of underwater tidal generators with a capacity of 1.5 MW each. The project is to be completed in 2020 by connecting the power plant to a unified UK power system.
Four huge turbines have already been manufactured: three generators are made by Andritz Hydro Hammerfest and one by Atlantis Resources. The weight of each generator is about 200 tons. At present, they are assembled on the embankment of the Nigga energy park, from where they will soon be delivered to the installation site on the seabed by a specialized vessel Neptune.
Externally, the tidal generators, due to the three-blade scheme, have much in common with wind turbines . However, the size of the underwater blades is much inferior to the windmills, which is associated with a denser aquatic environment. The turbines are equipped with a swivel mechanism that allows the blades to rotate 180 degrees, thus reacting to changing undercurrents.
Installation of the first four turbines will be the beginning of large-scale project for the deployment of 269 turbines with total capacity of 398 MW, which will be able to provide power to approximately 175,000 homes UK.
