Saying it is the world’s first multi-turbine tidal marine hydrokinetic (MHK) energy project, tidal power developer Atlantis Resources officially unveiled one of the massive turbines for the 6-MW MeyGen Phase 1A project today at Nigg Energy Park in Scotland.
The 1.5-MW Andritz Hydro Hammerfest horizontal-axis tidal turbine unveiled today is about 15 m in height, can reach rated power at 3 m/s flow-speed and has active pitch, full-yaw capability in its 18-m-rotor diameter.
MeyGen Phase 1A is the first build-out phase of the MeyGen Tidal Energy Project in the Inner Sound of Pentland Firth. Edinburgh-based MeyGen Ltd. holds all of the assets of the project and is the entity that has entered into all contracts with suppliers in relation to the project.
When completed, the tidal MHK project will have four 1.5-MW turbines; one Atlantis and three Andritz Hydro Hammerfest turbines. When deployed, the units will be fully-submerged and have a minimum of 8 m clearance to the sea surface at lowest astronomical tide.
Meygen Ltd. said it remains on track to deliver first power to the grid later this year.
In June, the project successfully connected to the 33-kV Ness of Quoys distribution network in Caithness following the successful installation of one of the longest underground 33-kV power export cables in the UK by network operator Scottish Hydro Electric.
The connection required more than 24 km of distribution network upgrades, along with infrastructure upgrades at two substations, according to Scottish Hydro Electric.
Atlantis Chief Executive, Tim Cornelius, said, “This is the day the tidal power industry announced itself as the most exciting new asset class of renewable, sustainable generation in the UK’s future energy mix.”
Ocean Energy Europe Chief Executive, Remi Gruet, said, “The MeyGen farm is an important pathfinder for the sector and will further prove the viability of tidal energy as an investment opportunity.”
Meygen Ltd. said once constructed, Phase 1A will run for about 25 years, at which point “it is proposed that it will be decommissioned.” But, the company maintains it is holding open the option to re-energize the project.
