Ampeak Energy is developing the potential of tidal energy through its MeyGen project in Scotland, where underwater turbines are converting the powerful currents of the Pentland Firth into renewable electricity.
Located between mainland Scotland and the island of Stroma, MeyGen benefits from some of the strongest tidal currents in the UK. Its first phase comprises four turbines, each rated at 1.5MW, providing installed capacity of 6MW. The project has been generating electricity since 2018 and passed 50GWh of cumulative generation in 2023.
MeyGen demonstrates how tidal stream technology can operate in demanding offshore conditions and contribute electricity to the grid. The turbines work in a similar way to wind turbines, using moving water to turn blades connected to generators. However, water is considerably denser than air, allowing tidal currents to carry significant energy.
One of the main advantages of tidal power is predictability. Unlike wind and solar generation, tidal movements can be forecast well in advance because they are governed by the gravitational influence of the moon and sun. This creates the potential for tidal energy to complement other renewable sources and support a more balanced electricity supply.
Ampeak’s longer-term plans include developing further phases at MeyGen. The site has potential capacity of up to 398MW, although this represents the wider development opportunity rather than current installed generation. A 59MW second phase has secured Contracts for Difference, with target commissioning dates between 2027 and 2029.
The project is also providing valuable experience in turbine operation, maintenance and offshore infrastructure. Its development includes work on shared subsea electrical connections, which could help improve efficiency as the number of turbines increases.
