250 kW hydrokinetic turbine manufactured in Brittany

Since Fall 2016, a 4 meter hydrokinetic turbine MegaWattBlue is being built. The duct is assembled at the shipyard Chantier Bretagne Sud in Belz. This 4 meter diameter and 6 meter duct length will streamline and speed up the current speed of 40 %. 

The base of the turbine is assembled in Navtis shipyard in Brest and the 250 kW alternator is on test phase at Bernard and Bonnefond Office in St Etienne. 

The tidal turbine will be set with its innovative self-buoyant base during Fall/Winter 2017/2018.

Guinard Energies is pleased to announce its participation at the SEANERGY 2017 show, the 22nd and 23rd March in le Havres. Our team will welcome you and answer all your questions at our stand.

We presented our technology and our power assessment device Poseide at the Euromaritime 2017 show from January 29th, to February 2nd.

POSEIDE achieved an hydrokinetic power assessment campaign in French Guiana

The hydro kinetic power assessment system POSEIDE is just coming back from French Guiana!


It has been successfully deployed to measure the available power around the "Salut" Islands, owned by the CNES : French Spatial Studies Center. The small MegaWattBlue turbine, with its data acquisition system had the chance to enjoy the warm and turbid water coming from the Bresilian stream.

Did you know...? The current around the "Salut" Islands was famous for beeing fatal to the convict of the french penal colony!

The measurment campaign lengthed eight days, from 8th to 16th of november, over the whole tidal range. The mission was led with success by the Guinard team, with help from the French Army 3rd REI (a.k.a "Légion Etrangère"), which provided the nautical support "Anne-Marie", an equipment transportation barge, and its valorous crew.

The POSEIDE system was lowered in water by mean of a small excavator, which shows the particular handiness of the system.

Guinard Energies would like to warmly thank the CNES, which made the mission possible, as well as the men of 3rd REI for their astonishing and valuable support.

The POSEIDE hydro kinetic power assessment system will be ready by the end of 2016, to hopefully drive a new campaign, in Britany, or elsewhere.
