A Falmouth and Penryn based company is taking over the D10 tidal turbine in France.
The D10 was the first grid-connected tidal turbine in the country, initially deployed in 2015.
Located in the Fromveur Passage off the coast of Brittany, it provides clean, sustainable energy to the remote island of Ushant.
The turbine was previously owned by French company Sabella, which went into liquidation in January 2024.
Now Inyanga Marine Energy Group, at Jubilee Wharf, has obtained permission to operate it until August 2028.
The UK-headquartered Inyanga Marine Energy Group, with an office in Brittany, has been managing all offshore operations at the D10 site since 2016.
Diane Dhomé of Inyanga Marine Energy Group said: "All permitting for the D10 turbine has now been renewed.
"We really appreciate the great support our company received from the Brittany Region and the French Administration.
"We have a shared vision for the development of renewable tidal energy."
Since its launch in 2015, the 17-metre high and 10-metre wide D10 tidal turbine has undergone various efficiency improvements.
The technology has been validated and proven to have no negative impact on the local marine environment.
It has been operating continuously since its last deployment, managed by Inyanga, in early 2022.
Richard Parkinson, CEO of Inyanga Marine Energy Group, said: "We have been heavily involved in the offshore operations on the D10 for several years and we were saddened by the bankruptcy of Sabella.
"We are pleased that our takeover of the D10 tidal turbine has now been concluded by the courts and the new deeds are now being drawn up.
"The future is safeguarded for this iconic tidal turbine, which has enjoyed tremendous support from the local community.
"It is another exciting milestone for Inyanga Marine Energy Group as we move towards our ambition of being the world leader in tidal energy."
