Turbine Development History

Tocardo’s technology development started in 1999 and saw their first prototype produced in 2005. Since then Tocardo have operated more tidal projects than any other developer and accumulated more running hours than the rest of the sector's major developers combined.

The T1 was the first turbine developed by Tocardo and has been operated and supplying power to the grid longer than any other turbine in the sector, totalling over 10 years.

In 2008 a test and demonstration model of the T-1 turbine was installed in the sluice of the Dutch icon Afsluitdijk near Den Oever and connected to the Dutch grid. In 2013 we took the commercial T-1 turbines for extensive off shore testing in the Wadden Sea where the turbine was attached to a barge and was taken to the Marsdiep, known for its strong tidal currents. The motorized barge acted as floating foundation system that could be powered to simulate even stronger currents. We successfully tested and verified the turbine performance and energy yield and also tested the ability to operate within a local (island) grid .

The T2 comes next in line as a scaled-up version of Tocardo’s T1 architecture producing power ranging from 100 - 250kW. The T2 is to date the sector's most proven turbine with over 30 operational years across 5 turbines.

In 2015 five T2 turbines were successfully installed in the Eastern Scheldt Storm Barrier, forming the world’s largest tidal array. This had a combined peak power output of 1.25MW. Extensive testing, commissioning and optimisation was performed resulting in a fully remotely operated power plant. This site provides one of the highest tidal flows in the world with speeds reaching up to 6m/s. This makes it the perfect proving ground for offshore tidal sites. It also has a low-cost offshore operational burden as the site is easily accessible via the barrier structure it resides on.

Following 8 years of almost continuous operation the turbines demonstrated high reliability with no major turbine failures and accumulating many decades of data. The project proved invaluable for turbine technology and operational advancement and this is reflected in the new generation T3 turbine. In 2023 having generated over 30% of the EU's total tidal power to date, the Oosterschelde 5 turbine array was decomissioned marking a transitioning milestone as Tocardo moves from research & development to commercialisation. This success is highlighted with Tocardo having secured contracts to provide 15MW of turbines for a new project under the UK Government’s Contracts for Difference scheme. This represents 15% of total allocated capacity under this Auction Round.
