Enjeux et avantages

PV projects offer the potential to:

Create value for available space and assets:

Payment of rent in return for space on rooftops, in parking lots and on land under long leases

Renovate roofs:

Remove asbestos from fiber-cement roofs, in accordance with best engineering practice, 10-year guarantee

Leverage communication around sustainable development

Have a future stock of zero-energy buildings:

A remarkable strategic benefit in an era of soaring energy prices

No two projects are alike

Our engineering and design department examines and calculates each project according to the landowner's objectives and the site's technical and environmental features.

Enjeux et avantages

Wind energy projects offer the potential to:

Create a local source of energy generation compatible with agricultural and industrial uses, with ease of dismantling

Optimize an inexhaustible, stable and continuous source of renewable energy

Minimize land impact through the use of proven, reliable and mature technologies

Meet local electricity generation needs with a renewable source considered to be the most economical solution, after hydropower

Deliver a technical solution for electrical power production that is both independent of fossil fuels and meets mass or domestic electricity needs

Definition of wind energy

Wind is an energy source that does not deplete over time. Wind energy is the kinetic energy generated by masses of air in movement around the earth. It is an indirect form of solar energy: the sun's rays are absorbed into the atmosphere and produce differences in temperature and pressure. This causes masses of air to circulate and accumulate kinetic energy. A clean and non-polluting energy form, wind power generates neither greenhouse gas emissions nor waste.

Notre offre
  • Farm of 1 – 10 towers
  • Landscape and regional identity requirements met
  • Optimized benefits for the local economy
  • Support for local authorities to create value: creation and widening of forest paths
Enjeux et avantages

Biomass projects offer the potential to:

Create value locally with all operators in the wood sector

Promote shorter circuits by developing the local economy

Recover the region’s wood and forest waste for conversion to energy

Create a secure energy supply locally

Definition of biomass

Biomass is derived from the combustion of plant-based materials, mostly wood, and is used as a primary energy source. Wood energy is suitable for several energy applications, including the production of heat, electricity and biofuels. Significant development potential resides in the available wood energy resources in France, including forests, copses and hedges, wood industry by-products, end-of-life wood, short-rotation coppice (SRC), as well as biofuels (cereals, vegetable oils, agricultural residue, olive pits and more).

Notre offre
  • 10,000 – 30,000 metric tons of biomass inputs by region
  • 0.5 – 20 MW recovered for thermal energy suitable for the end-use needs of consumers
  • Technical and financial partnerships with local operators, including industry, local authorities, urban planners and developers


Enjeux et avantages

Biogas projects offer the potential to:

Create value locally with operators from a range of sectors, including agri-foods, agriculture, local authorities, supermarkets and hypermarkets and waste collection service providers

Generate power from waste, which has become a major financial and regulatory challenge

Diversify market outlets for agricultural crops by producing high-quality agricultural fertilizers

Provide an innovative treatment solution to improve waste management by local and regional authorities

Definition of anaerobic fermentation

Anaerobic fermentation is a process of decomposition of organic material by bacteria under anaerobic conditions (without air) to produce methane gas. The process generates biogas, a renewable energy source mainly composed of methane (CH4) and carbon dioxide (CO2), as well as compost. Biogas can be transformed into heat, electricity and fuel. A renewable energy source, biogas is an economically and environmentally sound option for the treatment of organic waste. It delivers an array of benefits, including diversifying market outlets for crops by the recovery of digestates for fertilizer, and the transformation of liquid manure into fertilizer products. Widely accessible and open to a broad range of operators in agriculture, the agri-food sector and local authorities, biogas can provide heat autonomy for users and deliver environmental benefits in the form of sustainable management of organic waste.
