The AR1500 tidal turbine , located at the MeyGen site in Scotland, recorded its highest monthly production since entering operation . During March 2025, it reached 372 MWh of electricity generated exclusively by natural tidal flow.
According to Proteus Marine Renewables, the unit operated with an average availability of 95% during the first quarter of the year. This efficiency enabled it to supply clean energy to hundreds of British homes, consolidating tidal energy as a stable option within the United Kingdom’s renewable energy mix.
Series 1 technology still in force
While the industry’s attention is focused on Series 2 developments, which will include the upcoming AR3000 turbines, the current Series 1 technology demonstrates unquestionable technical solidity. The AR1500 , in operation since 2017, is a horizontal-axis turbine with full yaw control and variable-pitch blades, capable of generating up to 1.5 MW at flow speeds of three meters per second.
This performance reaffirms the relevance of the infrastructure already deployed and highlights the system’s capacity for continuous evolution.
Series 1 tidal turbine performance still in force
The operational success is attributed to the collaborative work of MeyGen, SAE, and Proteus Marine Renewables, which has demonstrated that tidal generation is viable on an industrial scale and can also compete in reliability with other renewable technologies . The collaboration between these entities has been key to maintaining and improving the equipment’s performance both offshore and in coastal maintenance operations.
For its part, Proteus Marine Renewables is advancing new developments and recently secured a seat on the board of directors of Ocean Energy Europe, strengthening its role as a central player in the growth of the European marine energy sector.
With record numbers and a clear roadmap toward new technological implementations, the MeyGen project continues to position itself as a global benchmark in tidal energy utilization.
