Ampeak Energy’s MeyGen tidal energy project in Scotland’s Pentland Firth is demonstrating the potential of predictable marine power, with the site offering development capacity of up to 398MW and an established operational record.
Located between the north-east coast of Scotland and the island of Stroma, MeyGen occupies a 3.5km site where strong tidal currents create conditions for electricity generation. The location was identified by Ampeak Energy in 2007 following an assessment of global tidal resources, with the company subsequently developing the project.
MeyGen is divided into several development phases, with the first 6MW phase comprising four turbines, each with a capacity of 1.5MW. The turbines have been operating since March 2018, providing an operational base for the development of larger tidal energy arrays.
The first phase has generated more than 51GWh of renewable electricity, demonstrating the technical feasibility of connecting multiple tidal turbines to the electricity network. The project has also provided operational experience in turbine installation, maintenance, subsea cabling and the management of equipment in challenging marine conditions.
The turbines are mounted on substantial gravity foundations on the seabed and use underwater rotors to convert the movement of tidal water into electricity. Their operation is designed to accommodate the changing direction of tidal flows, allowing generation during both incoming and outgoing tides.
The wider MeyGen site has consented development potential of up to 398MW, making it one of the largest planned tidal stream projects globally. Its second phase comprises 59MW and has secured Contracts for Difference across allocation rounds four, five and six, with commissioning targets spanning 2027 to 2029.
Further development could increase the site’s generating capacity towards its full potential, although future phases remain subject to commercial and development considerations.
Tidal energy offers a different generation profile from wind and solar because tidal movements follow predictable astronomical cycles. This allows electricity production to be forecast well in advance, providing a potential source of renewable generation that can complement other technologies within the electricity system.
