The world’s largest planned tidal-stream project to date is the MeyGen project in Scotland’s inhospitable Pentland Firth. Here, ANDRITZ HYDRO Hammerfest, based in Glasgow (UK) and part of ANDRITZ HYDRO in Austria, is supplying three of the four turbines for the initial phase 1a. The project is considered to have the utmost significance for power gener-ation and potentially for the future of sustainable energy supply. The turbines have a capacity of 1.5 megawatts each, and a rotational speed of 14 revolutions per minute. The plan is to have 270 turbines operating in 2020, at a full capacity of 398 MW.
This requires careful engineering, manufacturing and assembly, ensuring the reliable operation and high performance of the deployed technology.

The tidal turbines will be placed in the Inner Sound of the Pentland Firth, in the waters that separate the northern Scottish mainland from Stroma Island. It is home to whales and dolphins and other marine animals and is well known for its tidal streams, which are among the fastest in the world, with speeds of up to 18 kilo-metres per hour. With a suitable water depth of about 30 metres and very high flow velocity of up to five metres per second, it is potentially one of the best spots worldwide for tidal power generation.
