ERHYGE project : a showcase of hydrokinetic turbine solutions in isolated areas

 September 2018, Guinard Energies Nouvelles’ technical team left toward Madagascar to commission its first off-grid energy production facility in rural areas.

In partnership with the NGO Gret, the local grid-operator SM3E, Ademe International and the Malagasy Ministry of Energy, grouped around the ERHYGE project (Rural Electrification by HYdrolienne Guinard Energies), it is in the village of Ambatolaona, crossed by an inlet channel, that the P66 turbine was installed to supply power for the village of 200 inhabitants.

In Madagascar, numerous production facilities in isolated sites have been deployed to provide access to energy, explains Flavien MARTINE of Guinard Energies Nouvelles: “100% photovoltaic off-grid power plant are common in Madagascar, however this configuration requires a large storage bank for the night phase. The Hydrokinetic turbine in a river or a regulated channel shall operate 24/7, hybridized with an extra production source will eventually reduce battery park dimension. That is the real interest of the multi-energy hybrid systems that we offer "

Since 2018, Guinard Energies Nouvelles has marketed other solutions similar to that of Ambatolaona. For instance that Nouragues research center in french Guyana or recently in Togo.

An operating survey in close collaboration with the inhabitants of the village

 In 2 years of operation, the P66 turbine installed on an existing bridge in the village was exposed to  harsh local environment conditions as indicated by Nicolas Ruiz, from Guinard Energies Nouvelles: “This showcase installation has enabled us to accumulate the operating hours of our hydrokinetic turbine and thus capitalized on this feedback in order to further improve the performance and reliability of our products "

Moreover since the installation in 2018, an association of inhabitants has been formed to take care of the operating survey, the invoicing of the village's electricity consumption or even minor maintenance work tasks (solar panels cleaning, electrical devices checking, turbine overhauling, etc.).

Fidèle, an inhabitant of the village, was also trained by the Brest company during the installation. He is now liable for weekly operating data recording and assume maintenance and interventions on cutting-edge electrical devices.

As mentioned by Fetra ANDRIANANTOANDRO, NGO Gret : « The inhabitants have made the facility their own and contribute more to its sustainability not only by paying for power service. »

Madagascar, a country with a high potential for river kinetic turbine

As part of the ERHYGE project, one of the main purpose was to carry out an assessment of the hydro-kinetic potential of the island. Thus, 80 villages, from the east coast to the far southern part of the country were analyzed. This enabled the mapping of potential kinetic turbine compatible sites in Madagascar.

A new order for Togo

Gbandidi electrification rural Project

At the beginning of 2020, German company Reusch Energietechnick, specialized in hydroelectric power plants, contacted Guinard Energies Nouvelles – Acti group to take part of a renewable and decentralized electricity production project in Togo.

Led by the consortium CIREG (Climate Information for Integrated Renewable Electricity Generation), the project aims to deploy a semi-mobile container, repositionable in a few hours, integrating a hybrid power plant composed of a hydrokinetic turbine, a photovoltaic set and a battery bank. After visiting different villages along the Mono River, Gbandidi in Agbétiko canton was elected both for the match between its energy potential and the needs of its inhabitants.



The production unit will be composed of a floating Poseide 66 hydrokinetic turbine positioned on the river by a swerve arm, a C66.2.6 Hybrid converter, a 7 kWp photovoltaic set and a 30 kWh battery bank. The energy will be used by inhabitants for daily needs such as powering refrigerators, freezers, electric devices or charging mobile phones.


A project in the DNA of the company

With its experience in Hydrokinetic turbine-hybrid production units in isolated areas in Africa and South America, it is quite simply that the company from Brest (France) have agreed to provide its expertise and solutions for this project. After the first hybrid unit of Madagascar has been commissionned since september 2018, various projects including French Guiana in 2019, this new order confirms the growing interest in Hydrokinetic turbines as part of rural electrification solutions.



The P66 hydrokinetic turbine, the floatting and mooring system with the electrical converter will be sent to Germany to the headquarters of Reusch Energietechnick by mid september to be assembled in a containerized solution. Prior to be sent to Togo at the end of October ...

And commissioned right away.

Deployment in South America of the Guinard Energies tidal turbine

Une installation hydrolienne au milieu de la forêt amazonienne !

For the last few weeks, the Guinard Energies team has been preparing in its workshops all the equipment for a future hybrid off-grid installation. This future installation will aim to provide the energy of the CNRS Nouragues Scientific Station in French Guiana.

Until today, the scientific station was powered from a photovoltaic installation. A generator provided the necessary complement to the power of high-consumption devices such as the COPAS (scientific device observation of the canopy, editor's note).

For several years, the CNRS has been involved in setting up and operating renewable electricity generation solutions and has therefore decided to take advantage of the restoration of the photovoltaic system to integrate a tidal turbine production. After a call for projects, the Guinard Energies solution was chosen. The P66 river version will be installed on a mono-float inked in a stream of current located opposite the camp.

Une collaboration multi-entreprises / laboratoires.

The photovoltaic installation will be realized by the company AES of Kourou with the installation of new modules on the ground. The C66 converter developed by Guinard Energies and Entech SE will manage the tidal and photovoltaic production to ensure continuity of service and management of optimal battery cycles.

This unique installation in this particular environment that is the Amazonian forest will be monitored and monitored permanently by the G2ELAB design office that will collect and analyze all the information from the sensors (weather, current speed, presence,. ..) and data retrieved from the conversion equipment. The objective is to realize a model of hybrid tidal and photovoltaic production unit design for remote sites.

Currently, the Guinard Energies team is preparing all the equipment in order to send it by cargo to the port of Dégrad des Cannes in French Guiana and then forwarded to the installation site by the CNRS teams.

The planned installation in early December will become the only tidal power generating unit operating in French Guiana.

One year of operation for the installation of Ambatoloana

A first in Madagascar

On September 20, 2018, the Guinard Energies engineering team connected the village of Ambatoloana to the hydro-electric and photovoltaic 100% autonomous and decarbonated hybrid installation.

For a year, the 250 inhabitants of the small Malagasy village are connected to this micro-grid and thus benefit from clean and reliable electricity.

It is in the evening, at nightfall, that the supply of electricity is most visible. Little by little light bulbs come on in the small houses and at the time when the activity stopped to give place to the silence, today the life continues in the evening, the schoolchildren can thus study, the grocery stores remain open later.

This project funded by Ademe International and rich in a partnership with the NGO Gret proves to be a great success and shows that today, the contribution of tidal turbine in off-grid facilities has a real interest as explained by Flavien, an engineer at Guinard Energies: "Off-grid 100% photovoltaic installations are common in Madagascar, but this configuration requires a large storage tank to cope with the night phase. regulated channel will operate 24/24 which in addition to the additional production input will also reduce the battery, it is the real interest of multi-energy hybrid systems that we offer "


After one year of operation, for Fetra, project manager at the NGO Gret, no hazards are to be reported and the system works very well, followed and maintained by Fidèle, a resident of the village: "In terms of exploitation, one person from the village formed by Guinard Energies on the technique and the operator on the management is enough to manage the tidal stream Ambatolaona, which proves its simplicity of operation, which is never the case in off-grid installations In Madagascar, this technology not only electrifies all households in the village, which is already a goal, but its robustness also allows for the multiplication of income-generating activities. "

Currently, Guinard Energies and GRET are working on new rural electrification projects in Madagascar. Several sites have been appraised and technical studies are underway to deploy similar systems in more than a dozen villages.

Guinard Energies hydrokinetic turbine range

Guinard Energies designs and manufactures a range of high performance turbines dedicated to estuaries and very low head streams. Thanks to the swivelling duct, the Guinard Energies tidal turbines recover twice more power than other turbines of the same size. Turbine installation does not require heavy civil engineering. Due to their compactness, the hydrokinetic turbine could be set near the consumer location.

Guinard Energies team has chosen to gradually improve their turbine and its power capacity. The product range starts with the P66 - 3.5 kW turbine (66cm diameter), already deployed on several sites in France and abroad. The P154 – 20 kW turbine (154cm diameter) will be deployed in Ria d’Etel during the first semester 2019. This demonstrator turbine has been built and assembled in the naval shipyard of Navtis in the context of MegaWattBlue project.

Installation of P66 In French Guyana

Guinard Energies has carried out demonstrations of its P66 tidal turbine, in Brest harbor last weeks.This hydrokinetic turbine will be deployed very soon in French Guiana.

The P66 turbine, 3.5 kW, will provide electricity to a CNRS research station, which is now powered by a genset. The inverter developed by Guinard Energies will manage the hybrid production system from renewables energies – photovoltaics panels, the P66 turbine and batteries, will provide electricity to the station in an optimum way.

Easy operation

The choice of materials and its small size simplify installation and maintenance operations. Those advantages will allow the hydrokinetic turbine to be exported to isolated areas, devoid of infrastructure. The turbine requires 1.50 m water depth and starts from 1.2 m/s of current speed.
