eolienne Morne-CarriereThe energy transition requires us to change our habits: to adapt energy consumption to production (and no longer only the contrary), to integrate communications technologies, to develop smaller grids (production close to the consumer), and to create viable business models in an open market.

Quadran works in several subjects:

Overseas renewable energy
Quadran has conducted several research programs for production forecasting and energy storage, two technologies which are invaluable to the continued development of wind and solar energy in non-interconnected zones as well as to overcome the 30% limit (legally, intermittent sources of power must not exceed 30% of energy consumption).

Electric vehicles
Electrical vehicles, a fundamental element of tomorrow’s clean transportation, are also a way of storing electricity, coupled with the grid, whose flexibility will be very useful. Quadran is working on an initial project for a solar recharging electric vehicle with 100% independence, to better master the strengths and constraints of this sector.

Quadran is developing, with its partner Comwatt, materials and programs that will optimize how the energy from a solar installation is used at the source, will economize energy, and will use its flexibility. Projects are already in the works, allying communication and the management of energy flows.

Biomasse cogeneration
In Metropolitan France, Guadeloupe, and la Réunion, Quadran is studying projects that will allow local biomass resources, which are currently scarcely used, to be recovered: agricultural waste, sugar cane fiber, or wood waste.

Participative projects, local initiatives

Quadran carries out projects that ally local residents, municipalities, and private partners thanks to legal tools that allow them to actively participate with various levels of risk.

Quadran has numerous years of experience in collaborative projects. We can pilot new and innovative projects with industrial partners, municipalities, engineering and design firms, universities, or research organizations.


A few examples of our innovative projects


EnR'Stock® - Storage and Forecasting
2011-2014 – Financing: BPI, Feder, Centre Region, Loiret Département, Conurbation Authority of Orléans – Partners : Artelia, Mécamidi, Saft, INP Grenoble, Université de La Réunion, EDF SEI
The EnR'Stock® project's goal is to determine the optimal conditions for the creation of a storage installation in the overseas departments, to facilitate the insertion of wind or solar power production into the grid. It uses a mixed technology of PSH (pumped storage hydroelectricity) and a lithium-ion battery. In Grenoble, a pilot demonstration is testing storage piloting strategies and defining an optimum.

Petite Place - Stored wind power
Guadeloupe, commissioning 2015
This project consists in replacing a wind power plant at the end-of-life with a wind power plant with storage in Marie-Galante, Guadeloupe. The storage responds to the 2013 wind power bidbook for cyclone zones. Turbine capacity 2.5 MW. Storage capacity 0.45 MWh. The plant contributes efficiently to the island’s electricity grid.


Désirade - Electric vehicles
Guadeloupe, commissioning 2015 – Financing: Ademe, Region of Guadeloupe, Feder – Partners: Villeneuve Location
This project consists in experimenting with the rental of electric vehicles that are recharged by the sun, independently of the electricity grid in Désirade, Guadeloupe. PV generator of 14 kWp. Dedicated fleet of 6 electric vehicles.


Comwatt - Self-consumption
Numerous installations use the "Indepbox" from Comwatt to manage their energy consumption and maximize their own solar power production. The box automatically selects the best operation configuration.

Rebecca phase 2 - Sugarcane fiber, local biomass
2013-2015 – Financing: Feder – Partners: CIRAD, INRA
The Rebecca project aims to create a cane energy industry in Guadeloupe and to develop biomass cogeneration units that use local resources. It is comprised of a variable selection component (CIRAD, a French public research institution), an agricultural component (INRA, French national institute of agricultural research), and an industrial component (Quadran). The project will eventually result in the creation of a 5 to 15 MW electric biomass power plant.

•  Mont du Pilat wind power plant - Participative wind power
Loire, commissioning 2017
This project is a 20 MW wind turbine farm. The project’s organization is innovative: to carry it out, Quadran created a SAS (French LLC) bringing together 120 shareholder residents of the communities involved, 2 investment clubs, 5 associations, and a SEM (société d’économie mixte, anonymous company held by one or more public powers).

•  La Valasse Ecopole - Public/Private Partnership
Hérault, commissioning 2017 – Partners : SICTOM Pézenas-Agde, Conseil Général de l’Hérault
This project consists in creating a 10,000 ton/year anaerobic digestion unit for household waste within the framework of a public/private partnership, the SEMPER. The project uses an innovative procedure for the collection and recycling of waste.

INNOVATION, a necessity in a changing industry

The electricity sector is undergoing profound changes linked to multiple factors (renewable energy development, the liberalization of markets, environmental problems, the economic crisis, etc.).

•  To create sustainability, we must invent and experiment with new technologies and know-how.
