D10 power curve certified by Bureau Veritas

December 1st, 2022

Sabella has taken another important step towards the large-scale marketing of its turbines by obtaining certification of the power curve of its D10 turbine, immersed off Ushant, in the Fromveur Passage.

This certification, carried out in accordance with the IEC standard (which sets out the rules applicable to electrical production equipment), confirms the turbine’s production performance according to the different current speeds encountered at the Fromveur site.
Specific measurements were carried out this summer under conditions that allowed the machine’s production to be validated, and in compliance with specific constraints, particularly in terms of current speed. Bureau Veritas was thus able to certify the production curves, but also the instruments used for the measurements and their correct calibration.

After the successful re-launch of the D10 turbine at the beginning of April 2022 and its reconnection to the Ushant island electricity grid, the turbine has been injecting electricity for 8 months now. This has made it possible to cover up to 49% of the island’s electricity consumption, thus demonstrating the reality of the decarbonisation process initiated by Ushant island.
