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.

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.

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.

Dans le cadre du programme d'Electrification Rurale par HYdrolienne Guinard Energies (ERHYGE), Guinard energies et ses partenaires GRET et SM3E ont déployé sur la commune d'Ambatolaona une unité de production d'électricité comprenant une hydrolienne P66, un ensemble photovoltaïque de 4kWc couplés à une solution de stockage sur un parc batteries.

Autorisation Environnementales du PREE 22 janvier 2019

 Le 22 janvier 2019, une délégation du Programme d’Engagement Environnemental s’était rendue sur le site d’Ambatolaona pour constater l’installation et a délivré l’Autorisation Environnementales.

Une délégation de la Direction Générale de l'Energie s'est rendue sur le site d'Ambatolaona le 22 janvier afin de constater le contenu effectif du PREE et délivrer l'Autorisation Environnementale.

 Rappelons que le Programme d'Engagement Environnemental ne s'attache pas seulement à un suivi du milieu animal ou végétal mais s'engage également sur la gestion des équipements (batteries, modules photovoltaïques…) arrivés en fin de vie et le suivi de l'impact de l'arrivée de l'électricité sur la vie du village, et celle de ses habitants.

The MegaWattBlue project is cofunded 35% by the ERDF (European Regional Development Fund) and 10% by Brittany region. This project participates in the marine renewable energy development and the transition to a low-carbon economy. MegaWattBlue is certified by Pôle Mer Bretagne Atlantique.

The study of the environmental impact of the tidal turbine has been assessed since the design and manufacture of the sub-elements to the deployment phase. Installation, operation and maintenance processes have been improved along the project. The project is carried out in partnership with IFREMER and ENSTA Bretagne.

Before its installation in Ria d’Etel, the P154 tidal turbine will undergo a series of tests in open sea environment to optimize its operation under realistic but controlled conditions. These tests are undertaken in collaboration with ENTECH SE Company and ISEN Brest School on the TSM Penzer vessel of Iroise Mer.

The first conclusive tests were conducted during those first weeks of 2019.

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.
