SAE unveils world’s largest single-rotor turbineThe turbine and engineering services division of Bristol-based SIMEC Atlantis Energy (SAE), a diversified sustainable-energy generating company, last month unveiled the design for a new 2.0MW tidal-power turbine system that includes the largest and most powerful single-axis turbine available on the commercial market.

The AR2000 next-generation turbine will be capable of accommodating rotor diameters of 20-24m.

It has been in development for over two years and builds on the lessons learned from the AR1500 deployment and operation at the MeyGen project in Scotland — the largest planned tidal-stream project in the world.

SAE ( has invested more than £5 million in the development of the turbine, which is expected to be available for sale to commercial developers in Q4 2019.

The turbine is offered as part of a complete rotor-to-grid tidal generating system, with an array architecture that allows multiple turbines to be connected in parallel.

The AR2000 will feature an innovative electro-mechanical pitch system, 360deg of yaw, upgraded onboard health monitoring and diagnostics systems, and optimised critical-system redundancy.

It will have a 25-year design life, with quarter-life interventions for routine maintenance.

Drew Blaxland, director of turbine and engineering services, said: “The AR2000 marks the culmination of 15 years of investment, relentless experimentation, rigorous testing and sub-sea operation.

“Not only will it be the largest single-rotor turbine in production, it will also be the backbone of a highly efficient and cost-effective generating system capable of deployment in each of our key target markets — the UK, France, the Channel Islands, Asia, Australia and Canada.”

Be seen in all the right places!
