Guinard Energies – 20/10/2019

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.

Visite du ministre de l'énergie sur le site d'Ambatolaona

Dupliquer le projet Ambatoloana

Ce samedi 11 mai 2019, le Ministre de l’Energie de Madagascar, M. Vonjy Andriamanga, accompagné de la délégation du Ministère de l’Energie, de l’Eau et des Hydrocarbures(MEEH) a visité l'installation de production électrique du village d'Ambatoloana.

Le projet a pour but de démontrer la faisabilité opérationnelle d’un système de production d’électricité hybride intégrant des hydroliennes. Pour le MEEH, « il s’agit alors de dupliquer le projet Ambatoloana sur près de quatre-vingt sites sur tout le territoire national dans la mesure où le taux d’électrification est encore au plus bas surtout dans les milieux ruraux », déclare Vonjy Andriamange, ministre de l’Energie.

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.

ADEME supports the Spidhy project

  • Funding of ADEME’s Investments for the future program in the Spidhy project within the framework of the call for projects “Renewable energy, storage and conversion of energy, intelligent electrical systems”
  • SPIDHY: Innovative tidal turbine installation system - Système de Pose Innovante d’Hydrolienne – a simple and economical solution for installation and maintenance of Equipment on the seabed
  • This system will help to reduce the costs renewable marine energy

Guinard Energies is supported by ADEME for the development of its Spidhy project. This innovative tidal turbine installation system allows commissioning and decommissioning of seabed equipment in an autonomous, fast, economical and secured manner.

In existing systems, the commissioning cost of a tidal turbine is comparable to its construction price. Indeed, the mobilization of specific ships with several hundred tons lifting capacities presents a cost sized to offshore marine operation. These OPEX are not adapted to marine renewable energy emerging industry. Focused on reducing the cost of MRE, Guinard Energies has developed an innovative base allowing the immersion of heavy structures on the seabed at a competitive solution.

This design, patented Guinard Energies, under the name « Camel Base » is an innovative self-buoyant base foundation. The two parts of this system can be filled in with water or air for the installation or removal phases. This system has already been successfully tested at a scale 1:16 at IFREMER basin test in 2015 and will be used for the 250 kW Guinard Energies tidal device which will be installed in early 2018 in South Brittany.

Tidal and river turbines are a solution for the future, increasing the share of renewables energies in our energy mix.

Success of Guinard Energies Tidal turbine demonstration

At the Marines Renewables Energies Forum set in Gulf of Morbihan(South Brittany) from 15 April to 3rd June 2017, Guinard Energies, conducted a demonstration of the operation of its MegaWattBlue hydrokinetic turbine in the Gulf of Morbihan. A boat reserved for local representatives and journalists, was able to follow the demonstration as close as possible and observe the power created by this hydro-turbine (300 kW for 8 meter diameter at only 2.5 m/s – the water currents velocity in the gulf can reached 3.6 m/s, ie 7 knots)

Guinard Energies aims to develop all dimensions of hydrokinetic turbines. Marine and river hydrokinetic turbine from 3.5 kW to 20 kW associated with a regulating and converting electricity hybrid system for isolated sites as well as larger sized hydrokinetic turbine up to 1 MW for only 8 meters in diameter and 7 knots of marine current.

A 4-meter diameter tidal turbine to be tested in Ria d’Etel in Morbihan (56) is currently under construction. Installation is planned for the year 2018. Smaller hydrokinetic turbines are under construction to provide a simple and efficient electrification solution for isolated areas around the world.
